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 988

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 468.

Remote command:

[SENSe:]SWEep:TIME:AUTO on page 1037

Harmonic RBW Auto

Enables/disables the automatic adjustment of the resolution bandwidth for Normal

(3dB) (Gaussian) and 5-Pole filter types.

The automatic adjustment is carried out according to:

"RBW

= RBW

* n"

If RBW

is not available, the next higher value is used.

Remote command:

CALCulate<n>:MARKer<m>:FUNCtion:HARMonics:BANDwidth:AUTO

on page 988

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.
