They seem to have a nice range of affordable DSO's. $345.00 US will get you the USB-powered Pocket Analyzer. Specs look good for the money.

For under $300 it's a near impossible ask for something that's pre-made.

I have had the parallax usb 'scope for over a year now, and it is a handy little gadget. Santa brought it Christmas before last. Yes it is a little slow, and a 'toy' but I've found myself three or four times no where near a Tektronix, but I had my laptop bag with me, with the USB 'scope in the pocket. It has always shown me what I needed to know, and you can't beat the price.

Looks alright for the money. Very limited though. Some sound cards have a 60KHz bandwidth. You could devise something that's homebuilt and on par for about $50.

i just cant understand why DSO-2100 is cheaper than Pocket Analyzer but have twice better performance

Even while the DSO-2100 is "acclaimed" capable of 100MS/s, it only has a bandwidth of 30MHz. That's DC bandwidth too. Realistically, the bandwidth for measuring say, a sine wave, would be probably much closer to 20MHz. Bitscope Pocket Analyzer's on the other hand can measure sine waves, in some cases beyond 100MHz. With only 25MS/s too! Highly sophisticated software smarts make this possible. The magic's all in the software.

I believe Bitscope to be entirely genuine with these claims. The author strikes me as being more of a scientist than an engineer out to develop something for 50 cents that would cost anyone else $2.

Hi,

I think that the DSO-2100 is a revamp of an old model with parallel port.

See:
http://freenet-homepage.de/kritikus/clicliclic/dso2100.html
http://www.signal.ru/e/oscilloscope/dso2100.htm


The software of the DSO-2100 USB has a basic interface which is almost
the same interface of the model with parallel port.

The same hardware is sold with different brand names.

I don't think that new software updates will be available in the future.

Best regards,

Luciano
