Issue Details

I have a NI 9218 and I want to acquire a IEPE sensor from the channel one and then I want to use the another one to perform an analog input acquisition.
Can I use the module with the excitation only on one channel?

Solution

To use this module in this way you must create one task using two different instance of DAQmx Create Virtual Channel.vi.
You can set the first channel for IEPE acquisition, with excitation, and the other one for a normal analog input as showed in the attached snippet.
