I'm using the Quarto as a PID bias controller for an optical modulator. To get an error signal for the PID loop, I need to sample a photodiode with the Quarto's ADC at a specific (triggered) time. This ADC rate is nominally 25kSamp/sec, but needs to be synchronized with another signal source that is the master clock for the system. Is there a way to do this?
The only thing I can think of is to use an interrupt trigger routing to enable the ADC for one sample and then immediately disable the ADC until the next trigger event. I'm not sure that will be fast enough, so I'm reaching out to see if there's a better way to do this.
