The NI 9202 uses a combination of analog and digital filtering to provide an accurate representation of in-band signals while rejecting out-of-band signals. The filters discriminate between signals based on the frequency range, or bandwidth, of the signal. IN NI-DAQmx, you use the AI.Filter.Enable attribute/property to configure a channel to be used for filtering. You can then specify the center or cutoff frequency (AI.Filter.Freq), the filter order (AI.Filter.Order), and choose a Comb filter response (AI.Filter.Response).
Refer to the NI 9202 Datasheet for additional details on filtering for this device.
