Thank you for your response. Is it possible to generate notch filters around 60hz in normal capture mode? I didn’t see that capability built in (I.e. filtering down that low).

I created a Math function (i.e. Band stop filter on a signal in WaveForms that I'm measuring) to filter out 60 hz heating system humming being picked up by a microphone that I'm observing. I'd like to record that signal while playing content into the microphone, but under the "Record to File" option, I'm only able to select the Waveform Channels, or Filtered versions of those signals. I used the Math function because the Channel specific filter options did not filter down to the 60 hz area. Is there a way to record the processed signal via the Math function to file? or even better, a way to use the built in Filter functions to filter down that low? Those show up as options to record! thank you
