Sweep voltage range with trigger

[AlexSludds]

Hi everyone,

I have an application where I have a source in my setup which is generating TTL trigger pulses at a rate of roughly 15 per second. The pulses are 16us long and 3.3V.

I want to program my USB-6343 so that one of the analog output channels will step through a list of 100 voltages when each pulse comes in. When the list is finished the output value no longer changes (though pulses may still be generated in the setup).

I am using pyDAQmx if that matters at all.

Thank you for any help you can give!

I'm no help at all on the Python syntax, but the idea will be:

1. Configure a task where timing is set for Finite Sampling and 100 samples.

2. Further configure it to use the source pulses as an external *sample clock* signal, rather than thinking of them as "triggers."
