How to trigger the DAQ at the start of the chirp signal.

[Saravanakumar]

I am using python to communicate with Signal Generator and MCC DAQ 1602-HS.

I setup the chirp setting in the Signal Generator. Then I turn on. Immediately I turn on the DAQ next line. (using python). I couldn't capture the start of the chirp. The DAQ start capture after sometime. 

The example code DAQ_Set_Trigger() is so complicated for me. I can't understand. Can you please give me code that will trigger the DAQ when chirp signal from signal generator turns on?

I have attached my code below. 

Thank you.

Hello @Saravanakumar

I'll need to know what your "chirp" signal looks like on an oscilloscope.  In particular I'll need to know the amplitude and duration of that signal.

Are you looking to capture the chirp or is that just your trigger?

Thanks,

Jeffrey
