3.1.49 Differential A minus B (A-B (N)) curve
Right click on the curve’s handle to show the differential A minus B curve.
3.1.50 Changing display filtering
Modify the display filters at any time during testing or when editing later to remove unwanted noise from the
recording.
Note, this will not affect the raw data recording (hardware filters) and the display filters can be
changed/disabled at any time!!
