Selects the channel for which the captured data is analyzed in "Harmonic" mode. Har-
monic measurements can be performed on all channels simultaneously. The results
are indicated by different colored bars and numbers, corresponding to the channel but-
ton color.

Scale
Switches the scale for the measured harmonic levels between logarithmic (dB) and lin-
ear (percent). The values are relative to the level measured for the fundamental fre-
quency.
