External Trigger Amplitude

[spri]

I am using an external trigger pulse to start outputs on AnalogOut and DigitalOut pins using the python SDK.  The Trigger Pins on the AD2 are so sensitive that they interpret slight jostles of the wire as a trigger pulse -- so my outputs start unexpectedly. There are functions to qualify the trigger on AnalogIn (hysterisis, lengthcondition, etc)  to wait for the right signal -- how do I do something similar for the Analog and Digital Out Triggers (because they seem to only have SlopeSet functions)? 

Also, is it possible to have the same external trigger line act as both a 'Start' and 'Stop' for a pin?

Hi @spri

The trigger IOs are basically digital lines with 0/3.3V logic and input threshold around 1.5V. There is no filtering available for these. Make sure the lines are driven properly, are not left floating. You could try adding pulldown resistor of about 10k.
The trigger can only start an instrument, stop is not available.
