Unable to detect Pulse Width Trigger via API (detectable via PicoScope App)
I am trying to setup a pulse width trigger in a Python code environment. The pulse width trigger works find with the PicoScope Application as shown in attachment. But with the API the trigger is not working as expected. The code is below:
Is there something wrong with the trigger setup in the code ?
Code: Select all
lower = sample_count_for_2us
upper = sample_count_for_5us
ps5000aSetPulseWidthQualifierProperties(chandle, lower, upper, PS5000A_PW_TYPE_IN_RANGE)
conds = [PS5000A_CONDITION(PICO_CHANNEL_A, PS5000A_CONDITION_TRUE),
PS5000A_CONDITION(PICO_CHANNEL_B, PS5000A_CONDITION_DONT_CARE),
PS5000A_CONDITION(PICO_EXTERNAL, PS5000A_CONDITION_DONT_CARE)]
ps5000aSetPulseWidthQualifierConditions(chandle, (PS5000A_CONDITION*3)(*conds), 3, PS5000A_CLEAR)
direc = [PS5000A_DIRECTION(trigger_channel, PS5000A_FALLING, PS5000A_LEVEL)]
ps5000aSetPulseWidthQualifierDirections(chandle, (PS5000A_DIRECTION * 1)(*direc), 1)
