Hi I was just shooting the review of this new sequent 5,000 X-series scope. It's a One gig. It's their new entry into the One Gigahertz scope market and I was actually doing an Excel comparison table between these either between all the various one gig scopes on the market. as usual I kind of got carried away in it and I spent more and more time and I thought hey, this had probably be better as rather than just putting it somewhere in that one hour long review video I thought I'd do a separate video actually comparing and looking at the different one Gigahertz bandwidth oscilloscopes on the market and see how they stack up.

So let's take a look. I'll show you my spreadsheet. please forgive me I have weaponized man flu at the moment I'm going to try and to hold it together. that's why the windows tiny and I'm gone all right.

So we have the Siglent 5000 X-series brand new. we have the Reigle 7000. although it's not a one gig scope I do actually have one here and I know it's another sort of cost equivalent one for at least up to 500 megahertz bandwidth. so I thought I'd include it anyway and they do.

Rygel do have a new an MSO 8000 series coming soon. There's a photo of it on the website, but I don't think there's any details about it yet and it's going beyond 1 gig. So maybe yeah, might have to update the spreadsheet when that one comes out. but I've got absolutely no information on that.

so at the moment Rygel's not in the one gig scope market. Then we've got the The Road and Schwarz RTM 3000 series of three double O 4 which is not to be confused with the RTB 2000 which is incredibly popular, lower cost cope. this one is a model up from that and you'll notice that it actually has the X 10 auto probe like the active probe power interfaces on here. that's why I included it in this as well as it goes to one gig whereas the RTB 2 Doublet 2000 series doesn't.

So the RTM 3000 series and we've got the Keysight 3000 X-series touch model which I have here in the lab and you've seen countless times and also at the Keysight 4000 series as well I thought I'd include them because this is like a bigger touchscreen it's you know it's got a few extra bells and whistles, but it's quite similar to the 3000 as we'll see and then Tektronix have of course just released like yesterday was it I Think it's yesterday or today Yankee Time released the new 3-series mixed domain oscilloscope and also the new four series as two extra models below the five and the six series they introduced. So they're going in this new series thing which is great. Now the three series is actually a mixed domain or MDO oscilloscope. You can see it's got the RF spectrum analyzer input down here and this scope has now replaced the MDO 3000.

I Think they might have or will be discontinuing the MDO 4000 as well, but I'm not entirely sure Anyway, yes, so that's a four channel plus spectrum analyzer and it looks to be based on essentially identical hardware cuz all the specs are pretty much the same as the MDO 3000. So I believe the front end and all the other acquisition and hardware stuff is exactly the same. So they've just repackaged it, put it in a bigger screen. They've got the now touch user interface with the with the new series interface GUI Thing that they are started with the Series 5, so just to standardize across the range I Think that's a smart move, but anyway, it's a shame that they didn't redesign the hardware.

so apart from the bigger screen looks to be identical. And then we have the new 4 series mixed domain oscilloscope. It's got the what they call a flex channel or whatever. exactly the same as the 5 and the 6 series.

It can accommodate either an analog channel or various active probes and current probes and voltage probes and also a logic analyzer as well. So if you want the logic analyzer and this, you have to sacrifice one of the channels. And that's been one of my criticisms of the 5 V series when it originally came out. and Zaca the same thing here on the 4 except the 4 series.

a little bit physically smaller than the 5 series, which is good because the 5 series, is absolutely enormous and it's only got 6 channels instead of 8, which up to 8 that you can get on the 5 and the 6 Series And it's not a mix domain so it doesn't have the spectrum analyzer input so it's just a regular MSO and then the Wave Surfer 3000 from Lacroix that was their lowest cost one current one gig option, although you know you don't hear much about Lacroix scopes that I do marketing very well. Alright, so let's go into this spreadsheet that I've compiled. You can see that the different scopes are across here. Siglent Rygar wrote in Schwartz Keys like 3,000 4,000, the new three and four series text and the Lacroix in the same order that I just opened the data sheets there.

I've got prices for various options are starting from 200 Meg 350, 500 and up to one gig if those options are available in that scope range. And what the extras cost: the arbiter, waveform generator, logic analyzer options the serial decoders I've got sample raid I've got member max memory depth I've got the type of display on it I've got information about the lowest of vertical range you've got the ADCs I've got the fast Fourier transform I've got the gated FFT I've got the update rate maximum update rate bode plot spelt whether it has Bo plot functionality, spectrum analyzer of course only the MDA is going to have that zone triggering segment and memory mass testing and some details and the ARB gene whether it's got the para now is this function which seems popular these days, the accuracy of the time base for those playing along at home, and whether or not Scott Color intensity display if you are an aficionado of the color graded display and peat detect and also maybe some sample rates down here. so let's take a look at let's go through each one of these options. this could take a while now.

let's cut right to the chase because that's the title of the video. A one gig bandwidth scope. The new Seagal in SDS 5,000 X-series is the cheapest one gig bandwidth scope you can currently get brand-new that you can currently get on the market and will go into brand new versus used at the end of this video. so stick around.

So this is a base model with no options now. Sometimes all these prices they're all in US dollars and they will vary drastically between regions or could depends on whether or not they've got bundles and specials some of them do which will mention briefly and yeah like it and often you can deal with, deal with the salesperson. they might throw in some options just to get the sale on a big high ticket one gig Skype so I you know I wouldn't be bar I wouldn't be spending like in a 14 or 15 grand here on a scope and then not asking them to throw in a few options I'm you know I'm sure they would. So as you can see the segment by far the cheapest is said almost 70 300 Yankee bucks Rygel don't have an option yet.

The new MSO 8,000 I Expect it to be priced probably similarly because well as Sigil it and Rygel are battling out that sort of, you know, entry-level market. even her one gigs not entry-level but in terms of entry-level manufacturers, they're not the top three or four now. I'll come back to the road and Schwartz in a minute. The Keysight 3000 t is 11 thousand two hundred dollars for just the base model.

The Keysight 4000 X is fourteen thousand dollars, so you're paying a lot more for that bigger screen. I Don't think there's a huge amount difference otherwise dual channel option or whatever, but there's not a huge amount difference between those and there might be a critical difference depending on your application and of course, any recommendations I'm making this video obviously are going to be contingent upon your particular requirements. Sometimes you may not go for the best value for money some particular scope in here they may only be one option because it's got the particular feature or spec that you actually want and none of the others do. So I can't possibly go.

this spreadsheet would be I don't know more than 100 rows long if I went in there and like did absolutely every conceivable option inside the scope and be horrific. So almost 15 grand for the 4000 X-series That's pretty pricey, but hey, the new Tektronix 3 series. Here is the thing with the new Tektronix 3 & 4 series. They really don't want you to know what these scopes cost and probably for a reason.

I think they have published on their some of their pre-release teaser marketing material starts from and and things like that, you know. But really these prices they I could not find prices publicly. Anywhere you go to the Tektronix website, you have to fill out this silly option quote form and you send it away with all the different options you want and I will have a sales rep contact you bugger off like seriously like come on, it's ridiculous. Anyway, so I could not get any prices on the the new four series.

I haven't got a series series, huh? But somebody on the Eevblog forum actually pinched some prices from the new Arc website before it went live and I think these prices are confirmed here for the three series as a base model I think their base model options are 5000 and almost 10 grand and then almost 13 and then 15 grand for the one gig one. So you know, pricier or the same price as the Keysight 4000 and that's not surprising cuz Tech and Keysight consider themselves main competitors so they're obviously going to be price matching in the various categories. That's just they've been doing that for decade. But I Of course, expect the new four series because it's a much higher spec to scope to be pricier than this.

And by the way, the 3-series MDO it's not an MD. Oh, when you buy it, it's just a DSO It doesn't come with the logic analyzer and it most importantly doesn't come with the spectrum analyzer option. You have to buy that separately. I Don't have a price on the spectrum analyzer option probably similar to the em the old MDO 3000 pricing and the Lacroix are pricing here from 4700 up to 10 grand.

so I'll just let you have a look at those now. let's go back to the road. and Schwarz They've actually got these prices work. Some of these were on special on various websites, so these were either trade prices where I could find them.

but Rohde & Schwarz I believe up until the end of this year. So pretty much yeah from here on out they are offering. but I Believe it's only on the 1 gig model where you can get all the options fully loaded included for one price. and this does vary to the buy regions.

The US I think is slightly different to the EU and other places around the world. and stuff like that, it's all the weird geographical pricing crap. Anyway, obviously if price is your only object and you want a brand new scope with 1 gig bandwidth as a bare minimum, obviously the Siglent is the clear winner here. There's just like it beats all the others by like 2,700 bucks.

So yeah, but I'll go into that later when we look at used things and stuff like that. But I reckon out of all these, by the way, if I've highlighted something green on here, it means I think it's a stand out and if I've highlighted something red I think it's particularly bad. Not necessarily a showstopper, but it's something you really want to think about before you have a look at the scope. I think that the RTM 3000 from Rohde & Schwarz at a width of a fade paper under 10 grand.

That is probably the best value for money in terms of like extra stuff you get like will go down to the different things down here. but I think that is the value for money we're not at the moment. depends on your location, depends on your bundles you can get and deals you can do and stuff like that because it's a 10 bit scope and that's really, really nice. so that's that's worth paying the extra for.

But hey, if you're strapped for cash on a new scope, the Siglent after that if you are really keen on the keysight and there's several reasons to be keen on it. Still, even though it's quite old in the tooth, it's There is a fairly significant difference between the 3000 and the 4000 series here. And as I said, unless it's got something very specific that you need, they're almost identical scopes. They set the for thousands physically.

bigger, has a bigger screen, but the resolution doesn't change. Look down here: 800 by 600 screen 7 8 and a half inch versus 12.1 inch. Great. It's bigger, but it doesn't gain you any extra real estate for viewing your waveform.

So yeah, you know I'd Unless you needed the 4000, I'd be probably still looking at the 3000 and the new Tech 3 series Mdo at 15 grand base. Once again, traditional tech price in its you know, it's sky high, it's the most expensive of the group, and the 4 series is going to be above that again. So unless you're really got moist at the thought of having a tech scope on your bench at a one gig one then, well, they're very pricy options. They just don't seem to do pricing and value for money that well.

but you know they're no doubt good scopes. But you know, well as we'll see down here, there's a few red bits, so go into that. and the Lacroix 3000 at 10 grand I would much rather have the Rohde Schwarz are compared to the Lacroix at that. I Don't think there's any contest there, so the Lacroix is I Think it's probably out of this unless you're a Lacroix fanboy In which case, that's fine.

It's gonna be a good scope, no doubt. but technically the most expensive on the lefts list in terms of serial decode options is their own Schwarz But notice, as I said, they do, will now bundle it together all in one and you get everything including the power analysis options and and flex. And you know, Canvas and all the all the serial options. Every single option on the scope fully loaded.

So yeah, that's that's real good market employee I Like that. Speaking of market employers, Rohde & Schwarz, the reason why the RTP 2000 series is very popular at the moment, It's not because it's a great scope, but because when they initially released it, they did this awesome deal I think it was like two and a half grand and then included full bandwidth, full options and everything. and they only released like 500 of them and everyone on the EU Vblog forum and everywhere else just snapped him up like that. It was like half price.

It was crazy. and you know you don't see Tektronix just releasing new scopes today. You don't see any, you know, launch day deals or anything like that. to get people excited, people just go.

Ah yeah, it's just like the 5-series but it's a little bit cheaper and me. but of course the siglent include the serial decodes as a stand, all the basic ones as a standard option and the Rygel's are included as well. The Rygaards actually got a bundle special at the moment. they didn't didn't normally include these, but yet they include them at the moment.

So these are the special bundled prices and they'll even throw in I Believe they throw in the herb gen, don't they? yep included they throwing the ARB gen as well. All the others are optional. Our general Eve maybe not, maybe the Rhoden Schwartz gives you all. Check it out.

I Do come on I Spend enough time on this as it is. so one of the reasons why the new Rygar 7000 didn't get people very excited. even though they've got their own new chipset than one of the big players and got their own ASIC the front-end ASIC and the acquisition ship their own custom ASIC So they're one of the bigger players now in that respect, but they just didn't price it right. it was.

It was just too pricey and really like me, you know, are you going to pick the you know? if you're after a 350 mega you gonna pick the right girl 7000 over the RTM 3000 and the most expensive our our waveform Jen was the Keysight 4000 at just over a thousand bucks. but it is Joule as opposed to a single but wave Jen but it comes free with the chipset. They put like five bucks worth of parts in it and they charge like a thousand bucks for it. It's the same with the Tektronix Mdo or the original series to get the spectrum analyzer.

in that I I think I analyzed it once. it's probably estimated the price. It's probably less than 50 bucks in parts because it's a very simplistic front head design. But yeah, anyway, they want to charge it a couple of grand for it or something.

Yeah, now in terms of sample rate, none of them really suck here. I Did mark the Tektronix em do three series as I read because even though it's five gig, if you're using the one gig bandwidth, then it's a you only get two point five gig samples per second. so it's interleaved so you have to have that. So technically, that's the worst of the bunch the other ones of course will have when you put on another channel.

But the MBO three Series I believe does it when you don't even enable the other channels. it's just at the sample rate. Oh, it's at the bandwidth that you require. So yeah, at the higher sample rate.

so Matt and the Lacroix here is no standout at Foggy samples per second, but it's more than enough for a one gig bandwidth, so no problems. The winner here was the Rygel with 10 gig samples per second. As I said, most of these were in live with the second or subsequent channels turned on. Now the maximum memory depth.

The new play is the Siglent and the Rygaards. They've really been pushing this area they have for like a decade now or something. They're both 250 Meg samples as standard, although the Rygel 7000 can go to 500 make samples if you really need that anyway. The RTM 3000 is no slouch at 80 of course and the Tektronix are three series a 10 Meg that's you know, it's enough open in the 4 series has got a lot of memory as you'd expect, and the Lacroix he's got 20.

That's more than enough as well. Now of course, the losers in this group and one of the biggest obstacles for buying a keysight now is that they still use that same mega zoom for ASIC which is what eight nine years old? eight years old at least. so it's very old they haven't updated. it's got the four Meg samples maximum and a lot of people don't worry about the sample rate.

it's more than enough and these are still great scopes. but if sample memories your thing, yeah, you want to think twice about the keysight And as far as the display goes, the standouts: Other new Tektronix, three and four series scopes. they've got full HD 1920 by 1080 and screens. They're all the models in this shootout are touchscreen so no worries there.

and most of them got like gesture II type man. So definitely the standouts there in terms of resolution. It's absolutely brilliant and I believe none of these increase screen resolution when you hook on an external screen either, which is a oh it's a real shame. you know, be nice whack on an external screen, get full HD on your I goalies, Sieglin or whatever or your keysight.

but now they don't do it anyway. The losers here are still the key side actually. I should actually mark those as red because they're still only 800 by 600. although the Keysight 4000 series is the biggest screen physically biggest if you don't count the real super expensive Tech 4 series which is might be priced out of this shoot out anyway.

the others are 1024 by 600 is popular across three of them and the road and Schwarz beats that by having 1280 by 800. So the road and Schwarz is the nest next best display option after the keysight jobbies. Now a vertical front end is a bit tricky and you've really got to read. go into the data sheets on this and take a look at the frame fine print.

Well, let's have a look at this sequence data sheet, shall we? and and see what this caveat is. Yeah, it's got 500 micro volts per division and they'll plaster that over the Bla specs. But what they don't tell you is you don't get your one gig bandwidth that you paid for. you only get 200 Meg bandwidth So little Asterix You see this little asterisks: double asterisks double asterisks.

Let's go down here below: 1 millivolt per division. the bandwidth is limited to 200 megahertz, so that 500 micro volts per division doesn't But yeah, that's only for the 350 mega model for the 500 Meg and the 1 gig model. Basically, they're all limited below 2.4 5 millivolts per division I Don't know why that exact number. That seems a bit weird.

Anyway, at the bandwidth is limited to 200 megahertz. So basically you've got to go to the 4 or 5 millivolts per division whichever it uses before you'll get your full 500 Meg or one gig bandwidth trap for young players. So the Rye goal I believe has 1 millivolt over the full bandwidth. Please correct me if I'm wrong and I'll update the spreadsheet I might make it publicly available, maybe and we can add to it anyway.

Um, the Rhoden Schwartz is the stand-out It's the only one that gets green because it has a true 500 micro volt range over the full bandwidth and it does it with a 10 bit convertor. So if you want you know probably the best front end bandwidth option, you probably can't pick the road. and Schwartz they're the new 3 Series are MDO that's 1 millivolt over the bandwidth. They believe the 4 Series has a 500 micro volt range, but it's just software magnified.

1 millivolts or 2 millivolts I think yeah, it's the datasheet. Seems unclear about that. Oh yes, they claim to have the industry's leading vertical resolution, but but which is a 12 bit converter by the way. And as you saw there, if you want the highest resolution, the new Tech 4 Series is the best way to go 12 bit converter.

But yeah, pay through the nose room part. If you go into the datasheet, you're going to read carefully. It's only 12 bits at the 3.1 gig sample per second. If you go to the full sample rate there, you drop back to 8 bits.

Thank you very much. And by the way, all the Scopes I believe have the high res boxcar average on on here is a given. so I didn't really include that on the spreadsheet and there you go. Note: 500 micro volts per division is a 2 times digital zoom of 1 millivolt per division or a full-time zoom of 2 millivolts division.

Depending upon instrument settings, that's a bit. it's bit airy-fairy is what instrument settings they don't tell you. hence why I've put it in here mag of 1 millivolt or 2 millivolts. so I like now it's going on there.

if you do, let us know if you actually played with one and the Lacroix is 1 millivolt across the range I believe So the ADC As I said, the rodent two standouts are the Rohde & Schwarz and the Tech Four series. but Tech's four series is like double the price I think of the road and Schwartz for the same bandwidth. So if you're looking for a decent better than 8 bit converter their own Swartz is probably a best-of It's probably the only option really, unless you want to spring for the 4 series now. FFT The two stand outs here are the key sites once again, even though they're only 64k point FFT S which is buried by the two mega and 1 Meg of the siglent and Rygel respectively their hardware based FFT so they're really quick and I've done a video on this but I guess if you want pure resolution I think the stand out is the siglent the ROI goals not far behind it 1 Meg the road and Schwarz it doesn't actually say I couldn't find it in Danish eat I think I knew at one stage maybe it's in that FFT video I did, but not sure, but it's better that I believe it's better than the key side the Tech 3 series I Couldn't find it in datasheet, but of course it has the separate spectrum analyzer option, but I couldn't find the FFT number of points the 4 series oh I left it out.

No, there's actually nothing in there that tells you the number of points in the 4 series one either and the Lacroix has 1 Meg. So yeah, but I still think if you want like, probably the fastest updating FFT and it's almost certainly going to be the I think it's going to be the keysight. Serious, because it does hardware decoding these secret claims to do hardware decoding as well, but I haven't compared real speed on those. so I don't know.

it could be really schmick. it could be the absolute standout there. the new siglent don't know and then gated FFT the only one that has there. or I think the Lacroix might have it, but I haven't got one to play with I'm not sure whether or not it's available.

gated function is available on the FFT or not on the math function. but anyway, the keysight do deliberately have this and they're the only ones who are have it really. So if you need to gate what that means is time gating, so on the screen, you can just choose a particular part of the waveform and just get the Fft on just those parts and that can be handy for many circumstances. So I think the key sites really the only one that has that now Update rate.

This one's really tricky now. I can have a whole table of update rates and you really need to if you want to compare scopes like properly, because the banner spec is just the maximum update rate and usually that'll be only achievable on one or a couple of the time based optimized time based settings depending on the sample rate and the memory depth and all that sort of stuff. But of course this - even after eight or nine years. the mega Zoom for ASIC in the keysight 3000 and 4000 still does the business.

Still the winner at one Meg update Speed: the Rygel's the next-best at 600 k. The siglent the new siglent at a hundred and ten k is actually worse. It's slower than the than the model down from that. So I don't know what that like.

Why? Completely weird. So the road and Schwartz are put in red here is 64 K Update: Technically it's the smallest maximum, but it's a really fast and responsive scope so I wouldn't unless you're really desperate and for that I wouldn't rule out the road and Schwartz just based on that. So yeah, I put in red because technically is smallest. but I think the like the trickiest in this that I the the Lacroix is 130 K so it's fine.

and the Tektronix, three and four series. These are the trickiest because look at the four series. that's not a typo. that's not a hundred K to 500k.

That's 100 100 waveform updates per second on their brand new architecture they've been working on for years. On normal mode, if you turn the scope on use in normal mode, it's a hundred waveform updates per second. At best. it's a slow as a wet week.

Unbelievable. Even the lower three series is better with 50,000 waveform updates per second minimum. Now it doesn't tell you that in the Tektronix four series manual here it just says greater than 500 thousand waveform updates per second, which sounds fair. Fantastic.

But I Have been informed that it's actually, but that is in its what's that mode called that, the super acquisition mode which you deliberately have to switch on and then you get bugger-all sample memory with it. and then you'll get your five hundred thousand waveform updates per second maximum. But I've been informed that it's only a hundred in normal mode. not a hundred K a hundred? Correct me if I'm wrong.

Yes, here it is Fast. AK Technology High Speed Way to debug a design problem your first in digital Phosphor technology with Fast AK They've had this for like twenty years. have they now provide you as fast insight in the real operation? Instant waveform capture a greater than 500,000 waveforms per second, so it effectively implies it there. but they hide it in the specifications because they're probably too embarrassed to admit how slow it is if you don't turn on the far stack mode.

and of course you drop the memory when you do that. And text scopes have done this for no notes when he is now on something long time. so that is terrible. Muriel for their brand-new architecture, That's absolutely shocking.

Next is that bode plot which seems to be all the rage. Own keysight started it just and then Siglent copied them and everyone's got it. But you'll notice the new siglent, the new siglent. it does not have it.

whereas the other lower model signal cig, let's have the bode plot function. Why? why doesn't thing you want to have it? By the way, the new siglent, the ARB generator is not built-in You have to buy the external box for it and it plugs in via USB cable which is really annoying is just another thing to get lost or whatever. But yeah, it doesn't have it. Why um, right there.

I Goal: Parently doesn't have it. The road and Schwartz does have it. and in fact, the road ish force is probably one of the best specified scopes out of this whole lot. If you look at the specs, they go to town on everything as we'll see a bit later and they specifically say it does up to 500 points per decade in the bode plot so that's really fine Plot in that's fantastic.

The key side have is it has it. I don't know what their I think it's fairly coarse, it's nowhere near that and the three and four series does not have it. They're brand new flagship scope you know, just released does have a bode plot functionality when everyone else seems to be doing it and Lucroy not no-show and spectrum analyzer. That goes without saying the M do is the only game in town, the Tech 3-series empty oats, the only one who has a real spectrum analyzer, segmented memory and here's where often you have to read into the details now I Think no the new Tech series.

The brand New Tech Series 3m do because it's based on the heart same harbor as the old MDO 3000. It does not have segmented memory. This is basic stuff the Four series does, but anyway doesn't have it. but you have to look at the dead time and not all manufacturers specify the dead time.

That's the gap between when it's busy processing all the data it doesn't have time to capture anymore. it's got to store it and then and if you're any of your glitch or anything happens during that time that you're trying to churn that could you could potentially trigger on, you'll miss that trigger. So the standouts here is the Rhoden Schwartz It's got a 200 nanosecond dead time. The new C Glint has 2 microseconds rygel they don't specify it.

The key sites are a bit better than the Sieglin at 1 microsecond dead time check doesn't 3 doesn't have it and 200 nanoseconds. Oh, actually that should be green. Yes, the new keysight 4 Series matches, but it matches the road and Schwarz RTM 3000 and the Lacroix has at 1 microsecond. Yeah, same as the key side mask testing which has been on the key site for like 8 or 9 years now.

I Think they're the first to do, but they first know they weren't the first to do my mask testing but on a like a low-end Louis end scope they were and it's built into the hardware. But look once again the New Tech scopes. This is incredible. Neither of them have basic mask testing functionality that's terrible mural, the Lacroix has it and the mask testing.

The Siglent claims to be hardware based as well, but they don't give a figure for how fast it is whereas Keysight really talked up there how we're based mass testing 270,000 mast tests per second. Oh, it's blind his speed. If you need to do production mass testing, that's what mass testing is usually for. If you've got a particular waveform in a product that you're measuring on the production floor, for example, you usually automate this kind of stuff where you could do it standalone, but yet.

So if you've got a you're loading a reference waveform from a good product and then you'll put the mask of the errors around what the limits that are acceptable. and then the oscilloscope will simply go pass/fail and live and count the number of photos and and stuff like that. Very handy, almost essential for any sort of production engineering test environment. stuff like that.

And the AB Genja really have to go into the individual spec. I Got tired of looking at the individual specs here and I think there's a standout ad and I haven't got a consistent format. sorry for my daughter I Think them. Wiener In terms of highest frequency, out is the new Tech Series 4 Bit Man and you know the Tech series it is 6.

The 3 series. Yes, the 3 series has a knob. June Of course it does. There we go, there's the specs I forgot to include that.

Sorry. I'll just put yes. Ok, there you go. Who can update that later? There's no clear stand.

now. you wouldn't buy a scope based on you might if you had a requirement specific as I said, like a production test environment, you didn't want a separate box something like that. then you know you generate an arbitrary waveform or something like that, or just a basic sine squared triangle under software control with the only the one interface and the one instrument. then yeah, you know.

but I think they're all pretty much gonna do the job and that's why I didn't mark anyone as green because there's no real standout or no loser. Their power analysis mode the new cichlid is the only one out of a lot it seems to be. You know the in thing, it's been around. Care I think Keysight might have started I think and everyone's everyone now has power analysis building where you can hook it up, moldy channels up your power supplies, your current sensors and it can measure the efficiency, air power supply, and all sorts of whiz-bang stuff.

It's usually a very expensive, vast software option, but as I said, you buy the road and schwarz up here with all the options. You get the power analysis option which is normally like a grand or two. And of course manufacturers know that that is a specific function that a lot of people might need. and they ooh, milk that cash cow for that option on the power analysis.

Yeah. Time base accuracy I Thought I Throw that in there. The standouts are actually the the lower-cost ones a cichlid and the Rye goals down here, but the rodent Schwartz is also right down there at 2.5 ppm. The worst: I Didn't mark them red because there's not particularly bad.

The key sites that take three series empty I Think the 4000 series has external clock input, doesn't it? so you can take it from your lab. 10 megahertz reference. Anyway, the new 3 Series MDO hasn't got a great oscillator if four series is pretty good and the Lacroix is met as well. But yeah, these three of the standouts.

but you know it's nice to have a low ppm an oscillator I Think they should all spring for it in this price category. Talking about a one gig scope, come on, include er, you know, a 1 or 2 ppm oscillator in, you know, temperature compensated oscillator please. But of course some manufacturers like our siglent. They actually specify 1 ppm for 12 months, but over 10 years it drifts to through it.

Could they only guarantee 3.5 ppm over the 10 years? A lot of the other manufacturers don't specify that, so yes, so there might be very conservative. So the key sites and little croizon and the text may actually be much better than what they order. Not the tech, but the Lacroix at 10 ppm might actually be much better than that. but they may actually be aging that over a long period of time and not telling you.

probably over the calibration cycle which could which is often not 2 or 3 years for these scopes. some are only one year cow cycle though and for you color intensity display A fanboys the which ones don't have it. the RTM 3000 doesn't have I'm not a I'm not a fan of the color intensity display. some people are the keysight's don't have it, the new texts do, the Lacroix doesn't so that's important to you.

Knock yourself out now. Pig Detect This is interesting because it's like one of the main modes of an oscilloscope. and like, you go into the main acquisition mode and you'll have normal sample mode, you'll have average in sample mode, you'll have the high res you no, no increased number of bits, arrays, boxcar averaging mode and you have peak detect and there's one of them that doesn't have it and that is the Lacroix although I think Lacroix might be a bit infamous for not having a peak detect mode and I don't know why. Anyway, the standouts here are the Keysight at 250 picoseconds oh no, sorry and the 4 series tech at two hundred picoseconds, but the others aren't far behind a four hundred Suns mer.

The tech 3 series MDO is not that great at 1.5 nano. And to round this off, as I said the road and Schwarz actually really specify things a lot somewhat deeper than the other manufacturers are doing. They actually specify the maximum bitrate for the serial decoders 10 May, 25, 6, and 2 respectively. I Couldn't find anything similar for the other decoder, so if you know that information or you've tested it yourself, I can update the spreadsheet, but anyway, that's a that's a man thing unless you're dealing with specific high speed bus interfaces in that case as I Always recommend when you're especially when you're paying this sort of money when you're paying multi thousands of dollars up to 5 digits for an oscilloscope.

That's a lot of coin and so you should be getting a demo model from them and try it out on your specific application case. You might find you'll come a gutter because you needed to measure 3 megabits per second. can rate are and it didn't do it at only you know or you might find yeah you buy then you whiz-bang new marketed to the Hilt for series it does Everything includes the kitchen sink you might find it doesn't do the sample rate decoding or it doesn't have mass testing that you need it and you just didn't think of that or it's got a slow waveform update in normal mode or whatever. So anyway, as you can see over this whole thing, there's like there's no real clear stand outs.

You can count up the number of greens, but that's just my opinion. It might be a showstopper for you if it doesn't have something or things like that, so the key side has a lot of green there. But it's got some downside which may be crippling with the memory. For example, your mass testing.

You don't have that segmented memory, if that's a thing for you. Well, you can rule out the new 3. Series Just release yesterday. no thank you.

And if you need power analysis, the you see glints not going to do it and like stuff like that. So anyway, I as I said, if I went through and every specification and drilled in and detailed, it be more than a hundred items, Hundred and fifty items long or something. That's crazy. So I can't possibly cover everything here but this.

If there's something you want specifically added, then I can take a look at it all, send me an email and tell me what the figures are on a Wacom in the spreadsheet. I might make this available as a googly public googly spreadsheet perhaps. so you'll have to wait for my art review of the year. New Siglent SDS 5000 It's been slow progress.

It's a very blond, boring video and there's no I I Found a few bugs in it and and things like that which is common but it's okay. but it is the cheapest brand new scope on the market. so if you really knew that one gig bandwidth yeah it's the cheaper stays at cheapest 500. Meg yeah it's the cheapest 500.

Meg Oh no no. if you want to, if you're after a 500 Meg's scope, there are other models on the market that will just go to 500 like the RAI goal here. So I think GW in stick to a 500 mega and so yeah, there's that. That's a different thing I was focusing on one gig scopes here even though I did include the Rye goal.

but yeah, have a look at the road and Schwarz bundles if you're interested in the road. Schwarz because I think that with all the options bundled together, they've done that for different scopes. They've also done that for the RTB mm but only certain bandwidth models or something like that. Anyway, it's kind of complicated.

They've got these new bundle deals. rygel a bundling cuz there's sales I think have been not great on the new Reigai 7000. they just didn't It's not a bad scope but they just didn't price it. You know they really priced it at the high end the the equivalents you know.

Would you rather have the Reigai MSO seven thousand Eleven grand or the 10 bit rodents Schwartz With the bigger screen and everything and the better front end and stuff, it's probably. It's probably a no-brainer there, so you know it all comes down to from where you don't want value for money whether you want a specific specification for your particular requirements. And yeah, so I can't recommend everything. Even the old Keysight surprisingly actually holds up well.

it's not the cheapest thing on the market I Think they gonna probably gonna have to start discounting fairly soon unless they got a new scope on the way which I have no idea about. but anyway, it's long overdue. the Mega Zoom for ASIC that's got me a Mega Zoom 5 ASIC out there. come on first person to get info on the new any new keysight scope or the mega zoom 5 ASIC wins the Internet So although I haven't played with them, I have briefly played on my second Channel I played with a 5 Series tech trying to scope at the trade show.

Nothing really there stands out apart from the big screen and potentially the 12 bit converter on the 4 series of course. but that's got to be a killer price. it's just not in the same ballpark as the other one gig bandwidth and I think one or two of these go up to 1.5 gig. the new full series does and I think one of the others goes up to 1.5 gig as yeah, the I think the 4000 X might go up to one and a half gig.

So if you knew the extra bandwidth and all of them now including the siglent, they've got I think a nine hundred and something dollar one gig active probe. I've also got that here I might do like a little active probe shootout cuz I think I've got three active, one gig or 1.5 gig after you probes here. So I might do a separate video on that if you want me to give it a video a thumbs up or comment down below. do both because engagement, you know.

YouTube But let's say that you wanted a one gig scope and that was the thing that you wanted. You wanted a one gig bandwidth. reasonably modern digital scope. none that analog rubbish.

You wanted a digital one. Well, yeah, you can spend your seventy three hundred bucks on the siglent, but if you just need that requirement and you don't mind buying a secondhand or refurbished, then there's better value to be had in secondhand or refurbished for these high bandwidth scopes. I Think let's have a look. Alright, so let's open a new browser.

Let's go to ebay. the US ebay. I've not logged in although it seems to know who I am. Maybe I should have cleared my cookies.

there's that 121 GW and some thermal labels. Anyway, let's just go. Let's just like there's many I've done videos on how to search for oscilloscopes on eBay But yeah, let's just go one gigahertz oscilloscope like this and see what we can pick up. Here we go: 800 bucks, one gig for gig samples per second.

Good Tektronix There you go right. Pre-owned or best offer? Buy it now. So if you're just one one gig. Bandwidth in use, good condition pulled from a working environment.

Celery's Reseller Ii So it's a reseller. don't know if it's a test equipment reseller to have to look at their. what you do is you go into this store and then you have a look at their categories. Visit store.

You don't just look at their feedback. you have a look at. yeah, look their categories. Ashley: Kevin George What What? Dramat are These are the they must be their agents.

They must be names I assume their names of their agents who get secondhand stuff. So this is probably one of those professional eBay merchants. They've got a big stuff. If that's the case, it's going to David Let's see what Dave's got Dave's obviously getting what and a friend could tip.

What? what sent or mail system? Oh, is that one of those my or envelope printers I Think that's one of those envelope franking postal Franken machines or whatever. Anyway, there you go. So eight hundred bucks? Buy it Now It's probably no. it's likely to work.

Shows the waveforms. You have a look at the waveforms and see if there they got it hooked up to a sample waveform. Now you go. You might have to take their word for it, but anyway, it's worth a shot.

Freight Under bucks compared to eight grand, right? If you just need the one gig bandwidth, we know we know chicken dinner and should we even go through that There you go. Under a grand. Buy it now like and we can actually go down here And we could. we could search by.

I Wouldn't recommend searching by sample rate because a lot of people don't fill in those forms and you can miss bargains. I Got I'm getting into an eBay to Toriel now. Anyway, let's have a look at us sold and and completed items with that one gig. 400 by parts only Parts only pre-owned but yeah, look you can get them for is that pre-owned Is that working? But anyway, you can get these puppies for under a thousand but under eight of like for 800 bucks or best offer, Work it even.

That's reasonable. Ah, that's shipping to the Yeah: I Don't think it knows I'm in a straw. that's probably us shipping but that's it. Like if you just need the one gig bandwidth, what's the hand tech one? Giga It's one gig sample Ii labeled wrong sponsored posts from Hong Kong.

Give me a break. there's another tech Tds Oh no yeah, these are like really, there's a like 20 25 year-old scopes or whatever. but still they're You know if they're working for under a grand, they're gonna they gonna get you your one gig bandwidth. You spend more on the probes and you will.

You'll have to sort for secondhand probes and also Keysight. Keysight's got their own refurbished store so oscilloscopes and vector scopes and these are guaranteed by Keysight. They actually sell a lot of refurbished gear on here and maximum bandwidth. one one, one gig.

Let's take a look. they Lacroix I know I hit the wrong category. Don't shop Keysight on Ebay? There we go. I hit the category anyway.

they've got I'm not sure if the manufacturers have their own store on here but I guess I'd have been going for a long time and if you ask them they will discount. You don't necessarily have to pay the price on even though it's already discounted. From there it is from 16 grand to 8200 though they'll possibly make it, they're all best offers. Make an offer and ask them if they can throw in some options and I've heard on the Eevblog for them that they do throw in options.

so there you go so we can search 1 gigahertz Sylla scope. Just a broad search if you're serious, should go in there. 7 grand. There's the Msox3104t maybe don't quote me on that upgradeable or the new 6.

look at this series for 11 grand. Wow If you're gonna buy say the new Tektronix 3 series or this at 20 upgradeable to six gig 20 gig samples per second for channels, the Infinity Vision 6000 X is much higher sample rate and everything so that's a really specky high-end scope there. and it's just yeah. Wow And see, it's got even the options.

It's got segments of memory. It's got the memory upgrade. it's got the MSO It's got the advanced math Dmm, Whoop-dee-doo and remote. Our MLS remote I think so it's got these options and ask them if you need a specific another specific option just ask him are 30 days warranty.

There you go. Tested and calibrated, tested, all calibrated, whichever one I guess Lee Yeah Anyway, factory guaranteed from keysight. so yeah. absolutely fantastic and that's you can probably get that for 10 grand or under if you ask them.

I think if you put in a bid, you'd probably get that. So what would you get? the new? you know, much like seriously, why would you get one of these new ones unless you really wanted a new scope, Why would you get one of these new Tech's or even one of the new key sites here when you can buy a refurbished one but they've only got one so if you're lucky person out there who'll nab that, then good on ya. So anyway, that was a hugely long video. Thanks for staying with me.

If you got a right to the end, you can see why I wanted to pull this out because I knew this would be long. so I pulled it out from here I Go video which is already probably gonna be close to an hour long or something. So anyway, that'll come soon. but I'm I'm slow at the moment I got video just not motivated with the flu anyway.

Um yeah, hope you liked the video if you did. give it a big thumbs up as always, discuss and down below and let me know if you did. Almost certainly guaranteed it. I've got something wrong on here or I haven't got the best options.

Let us know in the comments. Catch you next time.
