Hi. I'm new to Signal Express and Labview 2010! We are acquiring voltage vs time data via DAQmx (NI 9215). Is there a way to change the time interval between data points? I think the current value is 1 ms. I have tried to look into recording options but so far I have not figured out a way to do this. Thanks.
This is probably easy but most of us old-schoolers in the LabVIEW forum don't use Signal Express. You might want to post your question over here:
I got curious and it is actually easy:
Add step, Acquire Sgnals, DAQmx Acquire, Analog input, Voltage (or whatever).
In Configuration tab set Acquisition Mode:
For 1 Sample (On Demand): set the sample period directly (it is software timed).
For Continuous or multisamples: Samples to Read / Sample Period = Sample rate (e.g. 100,000 / 10) = 100,000 samples collected over 10 seconds = 10KHz sample rate.
