(1) Order of harmonic
Results are displayed for each of 64 possible harmonic frequencies. You can restrict
the number of harmonics to be analyzed (see "Display Harmonics, Max No Harmonics"
on page 133).
Remote command:
(determined by suffix <n> in remote command)
(2) Power level of fundamental frequency
The calculated power level at the fundamental frequency. The graphical level results
are indicated in relation to the power level of the fundamental frequency. Thus, this bar
is always at 100 % or 0 dB.
Remote command:
HARMonic:RESult<m>:HARMonics1:ABSMagnitude?
(3+4) Power level of individual harmonics
For each harmonic and each input channel, a colored bar indicates calculated power
level at the selected harmonic frequency, set in relation to the power level of the funda-
mental frequency. The color of the bar corresponds to the color of the input channel.
The brighter colored bar is the current value, while the darker colored bar is the maxi-
mum value in the current measurement.

(5+6) Limit line and check for individual harmonics
If a limit is defined for the individual harmonic, it is indicated in the graphic (see "Limits,
Loaded File" on page 132). If the measured value exceeds the limit line, the back-
ground of the harmonic bar is highlighted red.
