I have a DAQ card NI 9203, and I need to use it to collect data from 4 different instruments. Two of the instruments have a maximum sampling rate of 1 sample/ s and two of them have a maximum sampling rate of 100 samples/ s. Is it possible to use the same card?

Why not sample at the higher frequency ( here 100 Hz) on all four channels??
You can always decimate the slower responding channels, offline

Thank you for your reply. By decimate, do you mean apply filtering?

Decimate (in this case) means discard 99 of 100 samples.
