Can AI_start.vi be configured or modified to provide a one pulse output per analog sample? Or is there a better VI to use? I'd like to do a buffered analog capture and provide one DO port pulse per sample to trigger a high-speed camera.
Yes, you will be able to obtain this behavior. The signal you will need to use is the analog input sample clock, which is referred to in LabVIEW as the STARTSCAN signal. The following KnowledgeBase explains how to use Route Signal.vi to output this signal on PFI 7:
