Many DAQ boards do not offer an internal lowpass filter.  One of the most important reasons to need a pre-A/D filter is for anti-aliasing.  If your signal has frequency content above your Nyquist frequency (1/2 your sample rate), that content will want to spill / bleed into your real measurements.

 

When your board doesn't offer internal filtering, and IF your signal has such high-freq content, it's vital to add hardware signal filtering in front of the A/D.  An RC filter is simplest, not the most effective, but sometimes sufficient.  Many other options are available.
