Save triggered data from 2 modules

[RyanC]

I am using SignalExpress (3.0) with USB cDAQ-9172, a NI9203 current and NI9201 voltage module.  After Acquiring data (continuously), I am using a software trigger on the 9203 current signal to analyze and save the triggered data (collected from all 8 channels on 9203).  However, I am not able to save the data from 9201 voltage module?  It looks like the software trigger only accepts a single module input (I think).  As shown in the attachment "trigger Input.jpg" I can only select 1 module as the input for the software trigger (either the current module or the voltage module)

Is there any way to trigger on a single channel and then save data from both modules?

Thanks!

Hey Ryan!

You can actually do all of this in one DAQmx Acquire step.  There is a tab in the Acquire step where you can specify your triggering.  Then there is a recording options tab up at the top where you can choose to save your data when the logging starts to a TDMS file that can be read in excel.

Thank you for the suggestion.  I was using a "Save to ASCII" step to save this as an Excel file.  I have not tried reading TDMS files in Excel before.  This might be the best approach.  I'll have to try this.

Thanks!
