FieldDAQ Filtering

Last Modified: May 2, 2019

The FD-11601, FD-11603, FD-11605, FD-11634, and FD-11637 can use 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. Use the AI.Filter.Enable DAQmx Channel property to enable or disable a filter. You can then specify the center or cutoff frequency (AI.Filter.Freq), the filter order (AI.Filter.Order), and choose a Brickwall, Butterworth, or Comb filter response (AI.Filter.Response). The filter selection applies to all channels on a bank.

Refer to your device user guide for additional information on filtering.
