Hi! In two recent videos, we took a look at the new Rygold HTO 4000 series 12 bit oscilloscope. Now that 8-bit rubbish. but it wasn't exactly a hobbyist friendly price. it was like 26.99 or something like that.

US Dollars Starting from, but as promised, Rygold set in their new 1000 series scope, it's white instead of black I Don't know. Anyway, be over. Um, it's the new HDO 1000 series. It's also 12 bit.

It's a lower sample rate two gigabs per second instead of four gig samples per second. but it's still a 12-bit 4 channel scope. and this one starts at 699 US dollars. So whoa, let's take a look because this is like a serious bit of hardware for a like a hobbyist friendly price.

But of course, just like the Uh 4000 series, it's lacking all of your modern stuff to get the price point down like mixed signal digital uh input, uh tree waveform generator. But if you need 12-bit performance, you can get it for 699 Yankee bucks. You know we'll see here on the EV blog. Don't turn it on, Take it apart.

except I Can't use this because it's a Phillips and it's going to have one of those talks. Rubbish things. Let's go but unlike the 4000 series, um, there's no external wire battery pack connection yet. Looks like they're still using the case because it's still got those moldings in there.

but they don't have the slidy door on there. They've filled that in so they're reusing the case anyway. We still get the 10 megahertz reference out 10 Meg reference here, an external trigger auxiliary out, and you get your LXI Lan your USB device and you still get the HDMI output at this price point. Nice voiding the warranty in 4K resolution.

Oh yeah, and it does lack the 50 ohm input of the 4000 as you'd expect to save cost but still on the silk screen. Come on. Seriously. So what we expect to see in this is the uh, same 12-bit um acquisition ADC and the same uh front end as well.

but uh, not including that uh 50 ohm path and look, Yep, they got the same metal work they just haven't included for the battery because that's where the battery contact was and they've just yeah, they've just added in the extra uh plastic in there in also haven't punched it out or something and of course that's a smart thing to do. You reuse all that I Expect probably a similar main board, but probably a different Fpga. a lower cost Fpga because it probably doesn't have the same grunt as the Big Daddy 4000 series because you know that's it's not exactly cheap. Oops, silly me.

I goofed up the price of this thing. Um, the two Channel version starts at 699. Yeah, it's um, not like you can upgrade it of course from two channels to four channels, they physically would not I'm sure physically. Even though I don't have the two Channel version, they physically would not let you do that.

Anyway, it looks like we've got the same two fan Arrangement here. So yeah, it's all exactly the same I had to leave that sucker off and Yeah Well yeah, it's going to be exactly the same. We've got the same bird that we had before everyone uh, corrected me on the bird as expected. I think this is going to be near identical.

Um, it's got exactly the same heatsink. Arrangement everything's the same I'll definitely take the front end off um and take off this, but the applications process is probably the same I'd say the Fpga they're going to be cut in uh, cost on that and all of your uh power supply that looks exactly the same as well. That's that off the shelf uh module that we uh, saw before, but it doesn't have the battery board in there so they're saving a bit of cost because they went to a bit of effort to, you know, do that and that all cost money to switch in the battery uh option. They got the same board up here for the uh 50 Hertz line uh trigger.

not that 60 Hertz rubbish. Except of course they haven't populated the circuitry up here which was the active uh probe circuitry so they won't have that board uh, physically installed of course. but everything else looks absolutely the same. Well, I'm actually stunned by what I'm seeing here.

It looks like it has exactly the same front end with the 50 ohm path that 800 megahertz bandwidth front end. I Noticed that one of the custom ADC A6 is missing, so that explains half the sample rate. Two gig samples per second instead of force. Obviously, the 180c is handling all four channels here and you'll notice that there's uh, four differential pairs going in there.

So that's how they're getting double the sample rate before. so that's the only thing missing. The Fpga is exactly the same. So this is running the Ultravision 3 architecture.

It looks like oh, but there's only one difference in the uh. memory up here, it's the same uh Rock Chip over here. I'm absolutely shocked there's only 200 Meg Bandwidth Scope has a genuine 800 megahertz front end with the 50 ohm capability and it doesn't even what. This software inside this thing doesn't have the 50 ohm capability, so it's yeah, it's on the front for a reason because it's physically in there I Can't believe this! A hackers are absolutely wetting themselves right about now.

I'm going to take a high-res photo and we'll do some uh, direct comparisons to see if we can see any differences. Wow! I Can't believe it. Check this out. They've used clearly the same PCB It's a different production run as you'll see, but it is the same PCB Obviously they've uh designed this so that they consolidate the PCB on both and it's near identical populated apart from the extra ADC and some stuff for the Uh front panel uh, active probe connections and that's it.

Look I'll get rid of my ugly mug here. Okay, so that you can see it now: I've got two uh two photos. This is the HTO 4000 which is a Brighter Image and I can switch this to the HDO 1000. Okay, and now we can switch back and forth.

So I've done my best to align this, but you'll see there's a few component positional uh, like minor as in their minor in mind, very minorly shifted things as I'll tell you in a minute. Unfortunately with Earth and view if I turn the paint on, it's sort of like sort of like resizes the image there if I've got the paint on. but still, it works. So like, clearly, we're missing the second ADC here.

Okay, right, that's all to do with the Uh front panel active uh probe compensation. So yeah, all of that stuff there, right? This chip here, whatever that is is still missing on both. Uh, and then we've got a little loan I think that was a low noise regulator um from the previous uh, tear down I'd have to watch that again, but that's obviously missing. Then we've got a couple of Uh filter caps missing here.

one's a little three pin Joby So clearly what's going on here is the one uh ADC here which is a custom Rigo uh chipset. That's their 12-bit uh thing, it's got the four pairs in here. the four differential pairs which all come out of here, that goes into there, that goes into there and that goes into there. but that is the only difference.

You'll notice. the Arctic seven. Check out the part number right here. It's exactly the same.

It's exactly the same so they haven't saved any cost there at all. And there's one number difference in the um DDR uh I think it's three or four memory I can't remember which one, but this is a two dp47 and this is a 2 GP 47 and the second line of the number there is exactly the same I have to look up that and put that overlay that uh, later. But uh, as you can see this, uh QR code here is uh, different for these and that's moved from over here. If I move my paint here, you'll notice that the date code down here the 37th week 22 for the Hco 1000.

Okay, that's moved to here. This is the 34th week 22. So this would just be like a natural difference in builds as they're iterating. Um, these things.

and uh, yeah. but I Have no doubt that they're going to consolidate the PCB once they've ironed out all the production. You know, everything's fine and hunky dory. The two Scopes will have absolutely identical boards in them.

Um, except for the chipset here. you got to be kidding me. Now, if you have a look at the front end down here, there is no difference. It's still got look, it's still got the 50 ohm path.

you remember how it goes or so. but yeah, it goes through this relay, goes through that that relay and that's the 50 ohm path. and then it's got the one Meg path which then this is the AC coupling here or DC coupling and it goes through the relay. And then there's the one Meg path and it's the exact same chipset.

Of course, it's the same chipset. That's what I expected. but they're obviously this has this 200 megahertz scope. That's the highest bandwidth they sell in the HDO 1000 series.

It's clearly got an 800 megahertz bandwidth with 50 ohm input termination. This is absolutely identical I Guarantee If you went in there and measured every single component, it would be the same. Wow, this is like a hacker's dream come true. I Think well you've got to Pony up the extra 999 dollars for the four if you want the four channels.

but for that it looks like in theory you get all the same Hardware except one less ADC So your sample rate drops which is not great. If you're talking 800 Meg bandwidth. then you know two gig samples per second for a single Channel and then you lower it. but still you.

This is crazy. Anyway, you'll notice other interesting little things like around here. For example, on the Uh HTO 4000 it's which is a older revision board. They've actually got the voltages 1v0 one V8 1v2.

they've vanished on the newer one, so that's interesting and you'll notice like little small positional changes that I've noticed. Check out over here as I change this. Notice the parts haven't changed, but like that little cap there. Watch that sucker, right it? It's not due to just differences in my camera angle, there's there's a subtle shift in the components.

They've made a subtle to get an extra Trace through. the PCB design is gone I need to like tongue at the right angle Shuffle more a bit this way and I'll be able to fit an extra Trace in there or something. So they've done some shuffling there. Look at that big unpopulated inductor there, which is unpopulated on both, but you'll notice how the silk screen it's it's physically and the pad is expanded.

It's a slightly different footprint and they're still unpopulated. so I don't know if you'll take a look up here at these fan connectors. you'll see that these will actually uh, slightly shift, but it looks like the footprint stayed the same as just the pick and place and it's just reflowed. There's an offset there on the Reflow so it's so.

we've got our JTAG header up here. The uh I think serial uart was here, wasn't it? I haven't probed that yet I might have to probe it I Just cannot believe believe that they use exactly the same front end. It's so I mean you know? Sure. Okay, this spent the NRE on the Uh chip.

The non-recurring engineering is what NRE is. They spent the money developing uh, the chip so you're going to use it in here, right? They're churning these things out by the I don't know I was going to say Millions Not quite. but anyway, they turn them out so I expected them of course because it's the same 12-bit everything's the same, right? and uh, the 1000 only has a 500 microvolt per division front end. but we know on the HTO 4000 was only a software.

Uh Improvement it's not a true 100 microvolt per division front end. so it's exactly the same front end. and it's got the 50 ohm path. Yet this thing in the software does not let you enable a 50 ohm input, but it's there.

It's physically there with an 800 megahertz bandwidth. So if you can somehow hack this thing to try and like fool it into thinking because you just simply copy the firmware and like make it into a like a HDO and it doesn't know the difference, that is a you know, maybe maybe there's like a couple of resistors that set the model somewhere. Maybe. but I don't know I'd I'd have to sit here.

leave it in the comments if you could actually see spot anything I mean I haven't spent a lot of time with this. There's another chip missing in here of course. Um, that's just a regulator. it's it's the same product.

Wow. I Did not expect this to be exactly the same product. The application processor over here is the same, the dram is exactly the same, and they're going to consolidate into the same board. I'm sure in six months time, if you buy the both products, that'll be exactly exactly the same revision boards and everything's hunky-dory But yeah, there's no difference.

Oh my goodness. So what sort of margin are they making on these? I Mean you know they've included all the bells and whistles in this? It's the same Fpga it's got Lake Inland They haven't even haven't even skipped on like the HDMI output or anything like that. They haven't even skipped on the 50. Ohm, it's it's embedded in there, you know, external 10 megahertz reference for example.

they're including all that sort of stuff in this. Bottom line: HDO 1000 It's a really interesting move from Rygold to make. Uh, you know, such powerful Hardware in their low end. Usually everyone we're seeing it time and time again with oscilloscope tear down.

so I'll uh the uh, probably you know they'll move. they'll remove things to um, do this. but it contains the same Hardware as the HDO 4000. just leaving off one ADC chip.

Surprised they even did that. So it's the hardware in oscilloscopes, the chips they go into making up this thing. um, a cost. You know, a relatively so little in terms of the margin of the that they're making on the Uh product.

I Mean obviously the margin's going to be way higher on the HDO 4000 because I Identical. Hardware Apart from the one chip, we're talking dollars. You know, tens of dollars difference in a two thousand dollar different scope. So maybe they're You know they're not making much if any margin on the H I'm sure they're making some right.

They'd be making some margin otherwise they wouldn't do it on the HDO 1000 and they're just making a killing on the HTO 4000. this is unbelievable I Just love doing this. I Could do this all day, but leave it in the comments down below. Um, if you can spot any subtle differences because I am shocked I Think there's going to be quite a few people working on hacking this HDO 1000 series.

Just I mean how much does this 12-bit ADC cost that they're that is the only component missing and the active Uh probe front end is physically missing the board and the connections and the cables and a couple of Parts on the board to enable that and stuff. But come on. so there's no changes under my head there. just disable my head so I can turn that back on.

and yeah, well. there you go. That is a huge like is that the first time in the oscilloscope Market that there's been such a lot a same exact same hardware and board used in a such a price differential. We're talking 699 to 26.99 We're talking a two thousand dollar difference and they haven't changed the front end.

but then again, they that's an amazing thing with front ends these days. they're getting so damn good that you can build an 800 megas, you know, a decent performance 12-bit dynamic range front end like low? not you know, 500 microvolt per division front end? uh, 12-bit uh performance? You know, low noise performance with I you know and you can afford to not even leave off like the 50 ohm thing like I go What? what? Unless they got some plan. maybe this scope is so early to Market that they do plan on adding the 50 ohm capability to that. Wow.

I'm absolutely amazed. So there you go. That's all for this video. I'm not going to analyze it further because I've already done in the Hco uh, 4000 video.

So thoughts and comments down below: just wait until the hack happens. I Uh, somebody, somebody's got to buy one of these and they're going to get to work. And yeah, anyway I might uh try if if I I'll do the uart thing, but I'll leave that to a second Channel video I might see if I can get something out of the uart and stuff like that. but yeah, anyway.

interesting huh? Catch you next time.
