Manual operation: See "Number of Harmonics" on page 236
CALCulate<n>:MARKer<m>:FUNCtion:HARMonics:PRESet
This command initiates a measurement to determine the ideal configuration for the har-
monic distortion measurement.
The method depends on the span.
●
Frequency domain (span > 0)
Frequency and level of the first harmonic are determined and used for the mea-
surement list.
●
Time domain (span = 0)
The level of the first harmonic is determined. The frequency remains unchanged.

11.6.11.3 Performing the Measurement
The following commands are required to perform a harmonic distortion measurement:
INITiate<n>[:IMMediate]
on page 629, see Chapter 11.6.1, "Performing Mea-
surements" , on page 626
11.6.11.4 Retrieving Results
The following commands retrieve the results of the harmonic distortion measurement.
CALCulate<n>:MARKer<m>:FUNCtion:HARMonics:DISTortion?
........................................ 722
CALCulate<n>:MARKer<m>:FUNCtion:HARMonics:LIST
...................................................723
CALCulate<n>:MARKer<m>:FUNCtion:HARMonics:DISTortion?
This command queries the total harmonic distortion of the signal.
To get a valid result, you have to perform a complete measurement with synchroniza-
tion to the end of the measurement before reading out the result. This is only possible
for single sweep mode.
