Multiple sampling - different frequency

Solved!
Go to solution

How can I read data from 8 analog input voltage channels using the DAQmx, specifying different sample frequency for each channel?

When I open DAQ assistant, I can choose only one sampling frequence for all the channel.

But for example, if I would like to use 8 signals on the same vi for different purposes, using different sampling frequency, how do I do it? Will I need to use 3 DAQ assistant one for each channel?

Hi simo,

 

you should use just one sample rate for all channels (usually the highest needed or possible) and decimate the signals as needed…

Thank you!

How can I decimate the individual signals?

Hi simo,

 

there are several functions in the Signal processing functions palette…
