An Update. First the good: I found out my triggers were not being set in the first place. I resolved that by: 1. I was not calling TriggerChannelDirections. I was told I didn't need to, but I think that was back when I was doing a pure pwq instead of a window pwq. With a window pwq, you definitely n...

Martyn, I think this explanation will suffice as it's actually pretty simple. But if not let me know. The trigger signal will nominally be sitting at either 0V or 24V. When I want a trigger, the signal will invert for 0.5 ms. So if it's already low, it will pulse to 24V. Or if it's already high, the...

Update: So first of all, I am now aware that what I want is actually a pulse width window trigger, because I care about the voltage level. A normal pulse width uses the threshold as the CENTER of the signal, and will trigger on a pulse deviating from that. There is supposedly some hysteresis, which ...

Is this still true and does it apply to 4000a? I can't find a pwq channel in the ps4000a programming guide.

Using PicoScope 4444 (uses the 4000a library) & the python wrappers I want to trigger when channel C has a pulse width of 0.3-0.7 ms, and I want to do that whether the pulse is inverted (so 24V -> 0V -> 24V) or noninverted (0V -> 24V -> 0V) Everything works except that as soon as I run the program, ...

Where did you FIND setup.py? I seriously can't find it in the SDK folders

Hitesh, that is not very helpful for anyone else who wants to do something similar.
