Need an O Scope, don't have a lot of room?

$40 and you can go 100mhz

http://www.saelig.com/product/PSPC017.htm

and grab the DS1102E 100 MHz 2-Channel Digital Oscilloscope for $399

i love this scope! would of liked to had the Logic Analyzer Version.

Another good cheap $50 logic "Sniffer":

http://gadgetfactory.net/logicsniffer/

Capture 50MHz+ waveforms on 32 channels
200Msps captures up to 100MHz waveforms on 16 channels
100Msps captures up to 50MHz waveforms on 32 channels

16 buffered channels, 5volt tolerant
 
Yes the DS1102E is a nice 100M scope.

Although I do like the SDS6062 because of the larger screen, and I can plug in a VGA monitor if I want. That helps when doing XY mode stuff, you don't have to zoom and scroll you can just see the whole screen.

Have you ever used both? I was looking at the Rigol, but the deeper buffers and ability to go battery op on the Owon are making rethink that plan in spite of the lower bandwidth.
 
I think you'd have to be crazy to not go for the 100mhz one for an extra $40. I've got the DS1052E and it's a great scope.

Many people don't know this but the low-end Agilent scopes are actually rebadged Rigol units.

Yes, I was aware Agilent used Rigol for their low end scopes.

My problem is that while the Rigol's got better bandwidth and sampling rate, it's buffers are much smaller (and, if you put it into 1 Gs/s, it can only store 16K samples, instead of the 1M it can do at 500s/s and lower)

Also, for $ 60, the Owon has a battery, so you can more easily get it near the equipment without one more cord to trip over, AND the display is bigger.

It's clearly lesser than the Rigol in the sampling rate and bandwidth, but the other factors give me pause.
 
Well I certainly never expected this thread to become and intelligent conversation, my bad. :)

But yes there are pluses and minus.

I know there are alot of people on the fence about getting a scope, and while they may find a good CRT one on ebay shipping can get expensive. Not to mention the 1'x2' desk space they take.

I mentioned it because it will cover the majority of things, and it's price point is pretty good. Oh and the battery option is nice since alot of folks don't have a bench to test on, and running another cord can be a PITA especially if you need that extra cord to run a light so you can see inside a cabinet.

Not saying my eyesight is bad (yet) but the bigger screen is a plus for me.

I think I'm leaning toward the Owon right now as much for the display as the battery - my eyesight IS getting bad (just got my first bifocals)

Thanks!
 
I would recommend NOT buying a Rigol scope. I have used 3 different Rigol scopes at work and they were all cheap junk. The feature set is great for the money, but they are not rugged. They wear out quickly from normal and careful use. Plus the probes are questionable from day one. If you want to use them occasionally they might be ok. But i would never buy one for daily use.

I've never used an Owon scope, so can't comment plus or minus. Some people like them. I don't recall ever hearing anything bad about them.


YMMV...
 
if i was a full on electronics shop, doing day to day repair and design work utilizing scopes/logic analyzers, etc, I would not be using anything under 2/3K .

ie, its like taking your car to the auto dealer to be fixed, they use a 10K Snap On Scan tool, not your cheapy $100 OBD Scanner from Autozone.

I did talk to the Rigol rep @ Dayton Hamfest, and I did voice my displease with the fact there is no "battery" option, he then kindly pointed me to there "higher" end products (cost upwords to 2K+)
 
It wouldn't be difficult to modify it so a battery could be used but I don't see what the problem is with having a power cord. Surely it's more convenient to plug it in than to have to worry about flat batteries all the time.
 
Kevin,

Did you see the Tektronix TDS-210 on CL for $200?
 
Kevin,

Yes I did. We've got a Ton of those here at work. I've used them for Vector stuff on occasion, but don't really care for the resolution. Plus I find it hard for me to see the signal on a grey scale screen. It's a nice scope for that price, just doesn't have the functions I'm wanting.
 
I'm curious - what is a good, basic scope for someone wanting to get into PCB repair? It sounds like the Owon would be sufficient, but I'm curious as to what is 'recommended'.

I realize that the question I'm asking is somewhat open-ended... I'm moreso looking for a quick primer on "what's good and what's not" in relation to PCB repair (of mostly golden-era boards - nintendo, atari, williams and atari/cinematronic vectors).

I've got a lot of boards that I'm wanting to learn how to fix and don't have a 2K-3K budget.

Any input here is appreciated!

To start with, get a good multimeter and a logic probe. The MM will tell you whether the voltages are right, and whether two points are actually connected or not, and the probe will tell you if the logic is moving or not, and thats a LOT of what you need right there. The scope comes in when you need to know whether the power is wavering, or if you need to look at audio signals, or (with a multi channel scope) whether two things are happening at the same time or not.

If you really haven't done any electronics work, don't start with a scope, is all I'm saying.

Loud and clear. Thanks for the advice.
 
Get a logic probe with audio beeps. MUCH more useful than a plain one.
