Lin Math C=A
Subtracts Trace B from Trace A point by point, then stores the results in Trace C in linear units. If
Trace A is in View On mode, this function is continuous and occurs every sweep. Results of the
subtraction are referenced to 0 dB. This often requires a reference level adjustment. For exam-
ple, if the reference level is set at –40 dBm, Trace A is at –50 dBm, and Trace B is at –55 dBm,
the C=A–B function places Trace C at –5 dB. Because this is off screen, the reference level will
need to be adjusted.
