grabbing analog data between 2 external triggers

[ckg]

Hello all,

I have a trigger signal that is not fixed frequency so I do not know the exact amount of samples that I can read from buffer with a known sampling frequency. I need to grab all the analog data between 2 trigger events. How can I do that ? Can anyone give an example python code for that ?

One approach is to connect the trigger signal to the trigger input and to an analog input and enable a CONTINUOUS+BACKGROUND+EXTTRIGGER scan. The first trigger pulse will start a_in_scan. Subsequent start triggers are ignored by the trigger input but will be recorded alongside the analog data. You must interrogate the data to determine when the second, third, fourth, etc., triggers occur.
