ISDS205B 5 in 1 Multifunctional PC USB Digital Virtual Oscilloscope + Spectrum Analyzer + Data Recorder + DDS + Sweep 20M 48MS/s

Received quickly and looks well built... The disk supplied with software is blank, so for that they loose 1 star....When set up, no complaints. I am perfectly happy with it...No point going into detail, it just works...

I have used the device now with a desktop PC running Windows 7 and also on a rather old laptop running Windows XP. To my surprise and delight the software supplied with the unit installed first time and without any issues on both machines. I have used the device in oscilloscope, spectrum analyser and sweep modes, on both machines. It took some time to puzzle out how to operate the unit but it was worth the struggle. For example, the setting of the "auto" button on the "oscilloscope" tab has to be correct for the spectrum analyser function (on a different tab) to behave itself. I have used the unit in spectrum analyser mode to look at the RF output of a small transmitter on 7 MHz and also, in sweep mode, to analyse the performance of a home-made Chebyshev filter. If the instructions were more comprehensive, I would have given this device 5 stars as it is very good value for money.
