Just bought a DSO-2090 USB oscilloscope.



I hope to turn my laptop into my oscilloscope. It's a bit of a gamble as there isn't much information on the internet. It's made in China and looking at the specification would appear to meet my needs.

The software package is excellent and I should be able to get very good screenshots of waveforms and monitor DC levels over time.

If anyone out there has one or used one I would be very interested to hear your views.

You're the reviewer (), I say you review this product! I'm rather interested in this, actually.

If "the management" think it fits in and they want a review they can have one!

Yea now you have to buy another expensive machine to test that device with to make sure it ok before you can use it...

Hey how much was that? I have a lowly 10MHz digital handheld scope without a PC interface... handy for troubleshooting and developing, but rubbish for recording data lol

I have purchased it from Ebay at £102.00 inc. p&p.

I'll let you all know what I think when I get it.

Pics of it in action !

The DSO-2090 came today and I had a very quick look just to conform that it was working.



Its bigger than it looks at about 8 x 4 inches.



Comes with two switch selectable X1/X10 probes which initially appear to be of quite good quality.



Software, user manual and USB lead. Note that it needs two free USB ports.



Software loaded smoothly with no problems at all. The above screenshot shows the 2V 1kHz calibration signal on both channels.



The above shows some 50Hz ripple on a small Ac adaptor.

Like I said I haven't had a real chance to play with it yet but would appear to do what I want and I am very pleased.

If you have any questions then please ask and I will try to answer them.

Regards

Paul

Interesting... any good for video applications (colourspace vector etc?)

I am not very well up on video and the theory behind it. This unit is the lowest specification of the range, suited my needs, with a 40MHz bandwidth and 100MS/s sampling rate. Don't know whether that helps?

Should be very handy for what you are planning on using it for.

Looks like it should be pretty accurate from the calibration signals.

looks like a lot of scope for the money

10MS/s certainly seems fast enough for some PSU analysis, and two channels will come in handy

Do you have access to a normal bench scope to compare it to?

Yes. I have an Iwatsu SS-7804 40MHz Dual Channel.

Hey guys, I just happened to see this thread and I'll add some input for anyone that's interested.

I got this scope a while back and the software that comes with it is pretty good. Here are some screenshots:

Here's the cal signal from the oscope itself.


Rise time.


FFT.



What I really like about the scope is that it came with a Visual Basic SDK to work with. With that, you have access to all the raw data you could ever need, and you write custom programs to do ANYTHING. Oh, and it also comes with Labview and VC++ project.

Well I hope this was helpful!
