Acquiring a video synchronously with an electrical signal is less trivial than one might think:
I would like to correlate events visible in the video (100 frames per second; FLIR/Teledyne machine vision camera) to events in the electrical signal (50 kHz sampling rate). I would save the video and the electrical signal to two separate files. Post-processing and analyzing the data to correlate the events offline afterwards would not be a problem for me. No need for any real-time signal processing.
The most reliable and precise solution which came to my mind was to generate a pulse (TTL) upon acquiring a video frame and record this pulse synchronously with the electrical signal of real interest.
Is it possible to set up a system of NI software (and maybe hardware) to meet these requirements?
I hope my specification is sufficient to discuss possible solutions.
