Tom Roberts of Autonerdz figured out the problem.

RFI was interfering with the usb converter. A grounded tinfoil shield cleared up the signal and stopped the crashing...

I got the new usb converter and PicoScope is no longer locking up and crashing. However, when looking at ignition primary volts & amps the data displayed is scrambled and does not reflect reality. I set the ADC 212/3 to view primary V & A on a vehicle, set up PicoScope 5 to save on trigger, and got ...

I don't think that high voltage is making it out of the ADC 212/3, I think that the parallel to usb doesn't understand the voltage out of range signal that is being sent to it encoded as parallel data. If I understand correctly how it works (and I probably don't :shock: ), the ADC 212/3 is sampling ...

Ok... I've been looking into this further and have come up with some further information. I was able to set the PicoScope back up on an older PC that has both usb and parallel ports. I also noticed that there seemed to be a pattern as to when the PicoScope software would lock up --> it would very co...

Hello Tom -

Yep... that would be me. I'll give you a call. Thanks!

Just to add a little more to my post above...

The exact same problem occurs when using PicoScope R6.0.12.2
