Good Day All.
I have a Picotech 2202 USB Oscilliscope, but I am having problems.
When I am using my Main PC with the Oscilliscope I can not use the earth clamp on my probe otherwise my computer powers down.
I understand the problems I am having are down to ground loops, from my computer and my bench power supply.
I have tried having the mains cable on my PC and bench power supply going to the same master socket, and I have tried sockets other side of the room with the same problem.
The only way I can get around the at this point in time is be using a old dell C400 (800mhz) laptop.
But I really need and would like to be able to use my main pc and bench power supply with my Oscilliscope.
From reading around the internet it seems I need something called "galvanic isolation"
Can anyone advice what I can do about this.
Thanks for your time.
Best Regards.
