Provided below is sample code using the picoscope libps2000A.so API for capturing transient waveform pulses with specified upper and lower thresholds and with pulse width qualifier enabled.

Re: Window trigger with pulse width qualifier

First I coded up the window trigger on Channel A which worked flawlessly. Then I added the code for the pulse width qualifier applicable to ...
