Multiple P eak Search and Marker List F or Harmonic Distortion Measurement
Harmonic components can be read (to 5 digits resolution) by moving
the marker to each harmonic . The marker and seven sub-markers
can be moved to peaks automatically . Amplitude and frequency of
all markers on the trace are read at the same time . The following
procedure displays the value of the fundamental and the harmonics:
