Dso-2090 Usb Oscilloscope

Recommended Posts

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 (:P), 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!

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

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. :thumbs-up:

 

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 :D
