Generate voltage with a trigger configure

[haiyueli]

Hi, everyone

I want to ask a general question about the data generation process.

I used "DAQmx start digital edge" to configure the task to start generate voltage on a falling edge of a digital signal in my application.  My trigger is a pulse train with a trigger freqeuncy 10Hz. Does the generation process stop at the rising edge? Or This is just effective when the first pulse appears and then the signal is generated continuously?

Thanks!

haiyueli,

With a DAQmx Start Digital Edge Trigger you will start your generation once the trigger condition is met (in this case the falling edge). It will not stop on the rising edge. It will keep running until the task stops, whether that be you stopping it or a finite generation.

What you are referencing sounds more like a Pause Trigger (example).
