The remote commands required to perform these tasks are described in Chap-
ter 11.6.11, "Measuring the Harmonic Distortion", on page 720.

Number of Harmonics
Defines the number of harmonics to be measured. The range is from 1 to 26. Default is
10.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:HARMonics:NHARmonics on page 721
Harmonic Sweep Time
Defines the sweep time for the zero span measurement on each harmonic frequency.
This setting is identical to the normal sweep time for zero span, see also "Sweep Time"
on page 324.
Remote command:
[SENSe:]SWEep:TIME:AUTO on page 775
Harmonic RBW Auto
Enables/disables the automatic adjustment of the resolution bandwidth for Normal
(3dB) (Gaussian) filter types.
The automatic adjustment is carried out according to:
"RBW
n
= RBW
1
* n"
If RBW
n
is not available, the next higher value is used.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:HARMonics:BANDwidth:AUTO
on page 721
Adjust Settings
If harmonic measurement was performed in the frequency domain, a new peak search
is started in the frequency range that was set before starting the harmonic measure-
ment. The center frequency is set to this frequency and the reference level is adjusted
accordingly.
