Looking for O-scope suggestions / reviews

[ScaleRobotics]

Here are a couple short beginners buyers guide/tutorial on oscilloscopes. I chose the cheaper one (25 mhz), and I have been pretty happy with it. Also, it doesn't use much space in the work room. The price was good too.

These might be too much for beginners, but maybe they will be useful to others.

Thanks for the links.

So how do you like the Owon scope? How long have you had it? Anything you dislike about it?
Does it seem well made, and like it might actually last for a decade or two?
I've had some really poor luck in the last few years with low priced imported (china) equipment, so I'm a little leary about some of that stuff these days. I know some of it is good quality and a great value, but there's also a lot of horrible junk out there too and I've owned some of it...

I've been thinking about my past, present, and possible future uses for a scope, and if I can get a new scope to last for 20 years, then it will probably be the last one I ever buy... because by then I'll be 70, and as quickly as my eyesight is failing I imagine my electronics career will be over by then unless they start making the parts way bigger again..

I got my first scope in 1974 (an ancient Dumont, packed full of vacuum tubes and had a 4" round screen) and I used it for 4 years.
I got my second scope in 1978 and I used it for 11 years.
I got my 3rd scope in 1989 and have used it for 21 years (so far)
I want my next one to last *at least* 40 years.

Thanks for your input!

I have a nice desktop digital scope with a color LCD, but I use my Velleman handheld scope far more often. In fact, I probably use it 95% of the time that I don't need dual signal display. The convenience of the small size is well worth it. The newer ones have better resolution, but even the older low res models are very helpful.

Steve,
It seems you will be hard pressed to find ANY electronic equipment last 20 years these days, regardless of the origin.

FWIW, I also have a cheap Owon, and it's fine. I got one with the battery, but because of the Velleman I've never used it unplugged. It is not as good as the Tek's, but far better than the 80's B&K crt it replaced. Plus, it's so cheap that even if you do have to replace it in 10 years, you'll get a better one and still spend less than the current cost of a name-brand.

I have had it for about a year now. It seems pretty well built to me. I only use it occasionally. I think you will love how compact it is compared to the tube scopes, and you can lift it with a pinky easily, compared to a dislocation on the older scopes...

I am far from an advanced user. Much more of a beginner, so you probably want some more input about it and it's capabilities. I previously had one of the Fluke portable scopes (older model 95?). I really like having separate colors for each channel like on the Owon. I can't seem to get their USB software to download the image to work, but it might be my lovely Vista, and not a fault of the scope. I have not really needed it yet, but I thought it would be cool, especially to share on the forum if the need arose.

I could see getting many more years out of it, as long as there are no unexpected smoking components. But I guess you never really know. I looked for a review on the Owon, but had trouble finding any.

The BK you mention seems to have about 4x the sampling rate, and many more features. But it is over twice the price. Probably a slightly better build to.

Thanks Norm, I was tempted by the digital/analog 2522C. Just couldn't quite squeeze $1200 out of my wallet. I was tempted also by the (full digital) Agilent 1002A, which was also $1200.

But it's a done deal now. I read the users manuals and whatever reviews I could locate for every scope I could find for < $1200 USD.
Agilent, Owon, Rigol, Techtronics, and B&K all had offerings that tempted me

In the end I decided to go with the B&K 2534 for $719.
When it gets here, I'll give a full report.

Thanks to everyone for your input!

The UPS man brought me a pile of new toys last week.
Got myself a Fluke 287 "True RMS" voltmeter, which so far I think I'm gonna like a lot but I need more time to play with it and learn all of it's features.

I also got a Aven "Digital Mighty Scope", in hopes that it would help me see some of those SMD parts I work with. It's a neat item. The software is a little quirky but it's OK. I think it will be a handy tool. Even with a 10x loupe it's tough for me to read the numbers on a 0603 resistor, but the mighty scope makes it REAL easy. Here's a screen shot of the thing at near max magnification.

You can sure see those tiny little solder balls around the pins. That board needs a good scrubbing! The resistor in the lower right corner is 0603 and I can actually read the value. Woohoo!
Kind of pricey at nearly $200 but I think it'll be a handy tool.

The 3rd item is my new B&K 2534 O-scope.
I'm afraid I'm not very happy about it so far, but in the spirit of fairness I'm going to contact B&K and give them a chance to redeem themselves before I post my review. We'll see how it goes.

Mmm. my work bench has that New Equipment Smell. I love it.

I'm unimpressed. The LCD screen is all filthy dirty on the backside of the glass, the cooling fan howls when it's cold, and the controls just don't really work very well.

Here's my review...
http://www.weirdstuffwemake.com/swee...anewscope.html

I haven't got any response to my email to B&K a few days ago. (??WTF??)
Digikey was good enough to respond though and sent me an RMA number so I can send this junk back.

The search for a decent scope continues. I don't know whether to drop my price range and try one of the REALLY cheap chinese scopes (I've really had my fill of cheap chinese trash), or up my price range and try and find something more... professional.

But the B&K didn't cut it so now I have to start all over again. Sigh...

I was able to get the software for the OWON scope working with Windows 98.

Here is an image. It had a little more resolution before I jpg'd it:




After reading Byte_Butcher's review of the B&K, I like my scope even more!

[Archangel]

Steve,
If you don't make it in the hand crafted goodies market, you might try Consumer Reports, Great review of that scope.

Walter,
You are doing a great job of making me think about that OWON scope, You got win98se to recognise it ? I just bought an HP1006 cheapo laser printer that is supposed to work, to no avail, won't set up as USB, and that's all it is. Maybe time to donate my old Tecktronics RM31A to The Smithsonion, all 80 pounds of it. . . Thing is I bet the OWON won't keep the shop warm at night like my RM31A does

One possible nice feature of the USB/PC scope or perhaps any USB enabled scope (Like that screen cap from the Owon Scope) is the ability to view it on a large screen monitor. Could make life easier on someone with vision impairment........

Steve, Thanks for the review.... I just noticed that the B-K scope also has a USB. Is it able to display the scope on the PC monitor?

-Bob

[Byte_Butcher]

Bob,
Yes, the B&K is supposed to be able to display to a computer screen also. And I believe you can control it from the computer. There was some a software disk from "COMSOFT" for that purpose. I never got that far in my testing. It's boxed up now and ready to go away.

I DID use the "print" button a few times, which worked good. It prints a BMP screen shot to a USB storage device. That worked great, but I didn't get around to trying a direct 'scope to computer connection.

Walter, I'm glad you got the USB working on the Owon. It's getting more tempting all the time.
