What is the simplest way of enabling IEPE excitation on my NI-4472 device

[MiamiVipul]

I have seen numerous examples in Traditional/DAQmx on how to enable IEPE excitation. I need to know the simplest way of enabling a single channel ICP excitation of NI-4472 DSA device. May be even a simpler example with DAQmx would help.

Here's a link ot the DSA Support page:

http://www.ni.com/support/dsa/default.htm

On it, there is a link to a KB which talks about setting IEPE in DAQmx and even your specific use case of only on a single channel.  Hopefully this gets you where you needs to be.

if you have the sound and vibration toolkit look at this popup. If it is too complicated just strip out what you don't need.

That helps for LabVIEW, but what about working with the NI-DAQmx API (nicaiu.dll) directly with text language calls?

Anybody know how to toggle IEPE power on and off using only DAQmx API calls?  I have tried the following sequence (parameters omitted) but it doesn't quite get it.  No errors on any of the returns but no power switch either.  Is there something else that has to be done?

DAQmxCreateTask
DAQmxCreateAIAccelChan (set excSource and excValue)
DAQmxCfgSampClkTiming (get error on commit w/o this)
DAQmxTaskControl (commit)
DAQmxClearTask

Thanks,

Cancel that.  Got it sorted out.
