different sampling rate for daq inputs

[Bgmnt]

i am using daq card 9025.

i wish to take two inputs at different channels but with different sampling frequency..

cani do this using daq assistant ?

or i wud have to use traditional daqmx functions?

could anyone shelp me with one example?

I would sample them both at the higher frequency, then decimate the data for the slower channel.

A 9025 is a cRIO controller.  I don't think that is what you have.  Perhaps you meant a 9205, which is a 32 channel AI module.

All imputs from a single module will have to be read at the same rate.  If you want to run at different frequencies, you will need to have another module.  What I tend to do in similar situations is just read at the fastest rate needed and then just perform an average on the channels that should be at a slower rate.

and what averaging function would that be?

I typically used Mean.vi (does not get any simpler than that).
