Hi, it's actually been five years since I did my last a fifty dollar? uh eBay Oscilloscope Video I've done uh, two of them and how to get a 50 Buck uh analog Crow on this digital rubbish on eBay for 50 bucks I Thought we'd do it again and see if we can actually get it. This comes about on the EV blog Forum where a beginner posted today that uh, they were tossing up between a Hitachi V uh Triple Two oscilloscope and a Tektronics R465 like you know, old school like early 70s vintage. both over 100 bucks and it's like okay, but anyway I Thought: let's see what we can find. Yes, sorry, this is going to be eBay Us: Okay, it's totally different.

much harder to find them here in Australia or in other countries or whatever possibly but sorry. I've gotta pick a country we're going to go into. uh, oscilloscopes and Vector Scopes category. Um, it's still got vectoscopes.

Anyway, they set it up like decades ago and it's It's stuck around ever since and they've changed the format now. I'm not a fan of this format down here anyway. Condition: What we want is used. You could actually sometimes you can miss Scopes if you choose a particular category or any item.

this refers to any item on eBay Some people won't put use, they'll actually put broken because there might be some legal liability in selling it or stuff like that. But we'll just go with uh used Scope Okay, and especially like it. It's probably better to try and get it from like, at least a competent uh used test equipment dealer or something like that. but usually you're going to pay a lot more.

Um, and of course I've mentioned you've got to set up eBay watch list. If you can't find anything, you're at least from doing these sorts of searches, you'll know various Search terms that you can set up and get email watch lists. That's how I get all my Bargains on eBay that's how everyone scores their Bargains on eBay usually is. uh by setting up keyword watch list, then you can not only set up keywords, but price filter as well, location searches and all that sort of stuff.

so you know shipping's too expensive. You can only search like locally so you can go pick it up. No we have to just choose Buy It Now or Best Offer or Oxen. We can't do multiple Uh ones so we'll just select them all at the moment.

But price, let's go a hundred bucks maximum. Let's see what we can get right off the bat here. A Techtronix TDS 320. now these are famous like failing and if they fail it's usually like they're hard to fix.

Push clear power on self-test pass 100 Meg Joby dual Channel looks in good Nick and that is 500 Meg samples per second so that easily meets the Nyquist uh sample rate. They're dated now but still a very usable scope. Once again, you'll have to search for like sold prices recently sold prices to see what they go for that's already got two bids on it. Okay, so you're probably not going to get that for your 50 bucks anyway.

let's move along like you don't want one of these old non-linear systems vintage stuff. Now you don't want any of that that tested. And Power on Tektronix 320 me there's there's once again, you might bid on these and you might use some sniping software to get these at the last second. I Know a lot of people hate them, but I use them myself.

I use Just Snipe. Um, it's just the one I've always used for like decades now. 24.65 Oh, look at that. That will get a lot of bids.

These are to 2465s are incredibly popular. It's just come on a few hours ago I think they've put it up for six days, but uh yeah, so you won't. You won't get that one you're possibly looking for. You know you're more non-mainstream Uh Brands Usually you might get your Hitachis, you might get your GW in sticks, You might get your uh Kika suis something like that.

Price and shipping lowest first. Okay, so look at this not available What that's a Kenwood for a dollar free pickup from Spokane Washington No I don't know whether or not that's a fake account or whether or not what's going on there. now that's that's dodgy as so uh yeah I Don't go for that. Okay, just to make this quick.

so I'm going to select the Buy It Now option. Okay, as I said, we might be missing out on Bargains by actually, uh, doing this. but let's just let's just go, shall we? We've only got the parts now. This is really annoying, but this is what you get when you search by the lowest price first.

How I don't know where people bother selling these things for like you know, 15 bucks and stuff like that Like it's just. it's just not worth your time to photograph and list it and everything else? Nope. I Probably should have put a minimum on there, but once again, you can miss. Bargains Yeah, this is just getting silly now, but we are looking for 50 bucks so if you want your Bargains you've got to do the time.

Oh there's so much crap on eBay us I'm on the 10th page. Now here's a leader: dual Trace Jobby for 25 bucks. That's a really old one but state of Ohio let you might go pick that up or something for 25 bucks. Yeah, you can get better.

We really need to sort by Price not by sort, by price, by shipping. they've actually removed it. You used to have the option that you can do just by price. So annoying.

Go into just go back to Best Match because we actually we're getting oscilloscopes here. Okay here's a kikasui right cos 50 60. my first uh oscilloscope was the Kikasui COS 5020. It was the 20 megahertz version.

These are excellent Scopes right? this is the 60 megahertz uh Dual tie base. In fact, at three channels because it's got a uh, you can use the external trigger as another. Channel I better stay near the power button there. but otherwise Ryan looks.

Got the Vernier for the delayed time base. they only show one Trace there it turns on but don't know how it works. It's the standard. either they do and they're bullshitting or whether or not they just generally have no clue what this thing is.

You know, there's this seller. There's a techtronix434 that's just like storage scope that's so old. honestly I wouldn't touch that. Okay, let's search for specific ones.

Let's search for Hitachi and digital storage. Now that's ancient those ancient digital story Scopes they're not worth it. Really? is a pre-owned 40 bucks like you might be able to pick pick up that, right? Nobody's going to bid on it. That one's actually quite nice.

Yeah, that's the VC 6020. Not oh, non-stop Oh, that's got storage. It's not hugely old in the schema things. Yeah, you can see uh, sorry I can't move my cursor, but you can see that the main time base is in X Y mode.

So that's why it's getting the dot. So and like this person obviously has no idea how to use it, or if they do, they're trying to hide the fact that It's got no trait. Yeah, that that's all you get. but heck, for 40 bucks, right? if you bid on that, especially if you can pick it up if you're in Michigan for example, because you'd definitely pick that up for 40 bucks.

No worries, Like you know, you may not pay postage for that. Perhaps if you're really looking to save cost, then yeah, you want to actually go and pick it up. But here here's a: Hitachi V Triple Two Oscilloscope. Now this could be the one that the uh person on the Forum was talking about.

Excellent scope. This was my first oscilloscope that I used at uh, my first job. Excellent. Great sharp tray.

Sort of beautiful. Very reliable, Very simple. It's only 20 megahertz. Uh, dual.

Channel You can get like 60 Mega, 40 and 60 megahertz versions. Excellent working condition. It shows both tracers there. It's a hundred bucks.

Would you pay a hundred bucks for it? Yeah, probably not. That's a little bit pricey I think. but there's one. There's a Hitachi part.

they're sold as Parts only and that's got the cursor one. So yeah, that that's got like oh, tracking cursors and everything it I would take a chance on that because look, it's all all the on-screen stuff is working that's obviously just picking up noise that effectively. Works 50 megahertz dual Channel with curses and tracking? Oh 69 bucks? Yeah, celebration. Not a guaranteed.

There you go: Displays, waveforms, some of the controls might need cleaning. Yeah, includes, but no probs. that's that's not bad at all. but yeah, that could be better.

V212 20 megahertz dual channel that that looks in good Nick that's your basic dual Channel 20 megahertz scope once again, 60 bucks You Could argue? You know there could be, you know, a better value, a better bang per Buck elsewhere that's old I wouldn't touch it these older Hitachi ones. No, you can get better. There's a VR 1050 that's 50 megahertz uh dual channel uh Joby Once again another one here. 50 bucks as is read Parts only but it shows dual traces there so it looks like you can still get uh, he's dreaming and 249 bucks it looks like you can.

You could certainly get a nice Hitachi for like 50 bucks. well under 100 bucks you can get five of them for 400 bucks. There you go. Whoa, what's a scope? Master Wow.

I've never seen that before. Isn't that fascinating? That's rare as ends up if you have one of those. but yeah, you wouldn't buy it 40 bucks. You might have a go, but you know there's a Hitachi uh digital score storage one.

Unfortunately, this is not going to have the real-time bandwidth. uh yeah, I don't know, but you'll probably find that doesn't meet the Nyquist sampling rate and its equivalent time sampling only these older school digital ones I wouldn't touch them but that looks in pretty good Nick but they don't show it powered on or anything so nah, tell him he's dreaming. 28 They have to be taking the piss. 2 800 US dollars for a vintage four Channel Um a storage? Come on? No no no no no no no no Oh well.

I just sort of my highest price. and these are funny. These are hilarious I Think they're serious? Oh my goodness. Now Searching for specific Brands like GW Instec uh for example, uh, like a really good brand that a lot of people don't know in here.

Um, jeez, uh, there's some real real pricey ones. Let's uh, let's go back by. uh Lois First, shall we? GW Instec digitizing scope for 109 or best offer, right? So so you're offer 99 bucks, 15 bucks standard shipping Springfield Ohio Aha, there you go. It's only 100 Meg samples per second so you know you're only going to get like, you know, 20 megahertz like, you know, effective, um real time, uh, bandwidth? but if that, but that looks like is that digital only? Yeah, that looks is digitizing I Don't think it's an analog Skype but oh geez, like if you can pick that up for 99 bucks I get like, oh, you know you'd be tempted.

That's it. It's still useful I've never ever used one I Don't know what the UI is like. Well what's what's wrong with the back? there. a bit of case, uh is damaged and stuff like that in working order it says but they don't show it.

but you know, like if you're after a digitizing scope with like 20 meg but you know it could be slow as a wet week. you just don't know. but still right and cheap. Um, here's a here's a nice one.

This is Uh I I actually put this uh to the Uh person on the Forum who was looking uh for a scope because look right because they were considering the same price point they were consider in a tech um scope. So I actually Linked In this one and for 150 Yankee bucks right? and free local pickup from Florida right? So it looks like I don't know. It looks like they don't ship it right so it might be only free local pickup. It's a more modern model working where like it's got full delayed uh time base and on-screen curses and everything.

Four available right? So they've got a whole bunch of them. Um, you know, probably from like a school somewhere that were just you know, uh, tossing them out. They got in some auction lot, but here's one over here. This person knows what they're doing right.

You can tell by the screenshot right? because the screenshot's got all the it looks like it's got the uh, zoomed uh waveform on there, right? No, that's not a digital oscilloscope. that's a um analog. That's an analog scope with uh, digital readout and cursors. But once again, 140 bucks.

they've got two of them available. They obviously work that looks a bit blurrier as the camera doing that. can't be a hundred percent sure there. but not a bad scope at all.

useful. And here's where you can start getting right a name brand because GW and Stick are a name brand. You can get one of their older model digital and digital. Scopes 150 Meg Offer them 150 if he can go pick it up.

Good working condition. more than 10 available. Yeah, they've got a whole Job Lot They they got like a pallet load of these from a school or something. GDs 820c that's on.

Look at GDs A20c 150 Meg that's got 125k memory 150 Meg 250 Meg bandwidth Receive color or monochrome display. Is this The color on mono doesn't matter. 20 Sampling rate. It doesn't.

What's the real-time sample rate on this thing? they're they're advertising as as a thing that where the the equivalent time sampling? it's not. You don't want equivalent time sampling. What is its actual sample rate? It's got to only be like 20 meg samples per second. No 100 100 Meg sample per second maximum.

But once again, you can get your 20 you know, 30 Meg bandwidth or whatever on that. No problem. Offer them you know 150 bucks or something and see if they take it. They've got more than 10 available so they probably willing.

They just want to clear these things out right from Toy arcade with 52 000 feedback. So you're definitely going to get it. It's definitely going to work right. It's got an older, clunky interface but geez like yeah.

150 Meg bandwidth? Uh, dual Channel digital scope I go with 100 Meg sample per second and Sample rate I I could argue 195 bucks? Yeah, a bit pricey but off from 150. oh we're getting them from Israel now or the finest beat up stuff it comes from Israel if if you're old school eBay you'll know what I'm talking about now. I've done videos on this before. uh HP like a 54 645 D still a very capable.

It's a mixed signal scope and it's it's 200 box. An excellent useful scope and uh, you know you can do it. You can do it yourself. Um, logic analyzer probes, mixed signal scope.

Does this sound like we've got dual tracers there? Uh, that's just a poor photo. What you'll get just that you don't get anything else. Um, but it Powers up it guaranteed. work in right.

pulled from a working environment. sometimes it's BS other times it's It's not this. This looks pretty genuine. I'd say E-Tech resale right? they said with 15 000 feedback.

the vibe is good so I just say yeah they just couldn't be bothered. Their photos aren't that great, just the contrast in the photos but it looks like it. It powers on for 200 bucks. Do we have any? Phillips Skypes Uh, not really.

Once again, I'm sorting by Price here and I've done a video on a really nice scope which is the tektronics. Uh, Triple Two Five, for example, goes down to 500 microvolts per division. Beautiful. Um, but once again, you know they're older.

They can have problems. but look, look what? I Found like more than 10 available in working conditions. Plural? Um, 99 bucks or make an offer? Are you kidding me for a tech? Triple two? five? Yes please. from surplus electronics Miami 3 400 Feedback right? They're obviously a professional.

test equipment. Merchant Uh, Merchant Make an offer, right? They might not all look like that, Perhaps. But and once again, they only show like a single trace on there. So geez, Imagine, if you're in Miami you pick one of those up for like, make an offer and for 80 bucks, they've got more than 10 available.

They'd probably take 80 bucks for it. I'll take two for 150, please. and then you double your chances of getting a working one or you keep one for spares anyway. I Don't want this video to be hugely lengthy, but as you can see, like you can pick up some potentially good, really useful functional.

Scopes Yes, you can get the 50 scope. It is it. It is still possible they've got make an offer there. offer them 150 like they've already reduced the price from 229 to 195 because a digital scope is going to be much more useful of course than an analog one even.

And it's I Said this on the Forum even and advanced analog one. You know with your dual time bases and your high bandwidth and everything else. I Would rather have a really low end digital one so they can do single shot capture, then have a you know, a top of the line bells and whistles. uh 2246? you know? Tech Um, you know, bells and whistles? uh scope.

The digital storage is more useful, but you know, if you're on a real budget. um, then you can easily pick up something useful for under 100 bucks. Easy even even for that 50 bucks. But once again, you don't have to go on eBay you can go on Craigslist or whatever similar thing here in Australia might have.

Gumtree For example, you might try auction houses and stuff like that. leave the name of your favorite like auction House down below. Here in Australia we've got Mannheim Grayson lines which isn't as good as it used to be and uh, there's some other Uh ones as well. in the US there's probably tons of them, but unfortunately, often at those Uh auction places are you going to be bidding against the professional test equipment.

People like the arcade here that get you know like they've got more than 10, right? They had at least 17 of these and they bought a whole palette load of this because the school was updating their Scopes and they all work. You know you might have to buy a pallet Worth or something like that so you're usually not going to pick up your onesies twosies often from these auction houses, but as I said, as nice as these like 2465 analog Scopes are from Tech and a lot of the tech, you can get a lot of the 300 series for example. As good as they are, they often have long-term failure modes um, and there's whole repair groups out there if you want to repair them. but generally you know if you're a beginner, you just want a scope that works.

So look for one, look for a listing that has you know the Dual Channel showing up or as you saw if it just has a DOT look for the controls to see if it's in XY mode or something like that and generally well, at least you know the EHT sections working out. you know 95 of the time it's you know it's going to be uh working. if you can like see a trace I would avoid like really ancient ones like this uh for example, although you know they're okay but like they're probably only going to give you uh, trouble and then you could argue that uh well, you know, do you get something like a really cheap digital one like this or for what? 350 US Dollars You can get a modern Rigo one, can't you? Unless inflation has caused them to go up like you know, so you don't want to pay too much, you can get one for way less than half what you'd get a modern scope for. Then again, you could argue the modern scope is like huge better bang per Buck than something like this for example.

But I reckon if you could pick up something like that for 150 bucks, you know that's a winner chicken dinner anyway. Um, leave your thoughts and comments down below. I Hope you found that video useful. If you did, please give it a big thumbs up and remember the EV blog Forum always linked down below Test Equipment section: best on the interwebs and yeah, that's where everyone addicted to, uh, test gear is on the EV blog.

Forum So there you go anyway. Catch you next time. Foreign.
