Return values:
<Harmonics> Returns one value for every harmonic.
The first value is the absolute power of the first harmonic. The
unit is variable.
The other values are power levels relative to the first harmonic.
The unit for these is dB.
14.5.11.5 Example: Measuring the Harmonic Distortion
//-------------Configuring the Measurement-------------
*RST
//Resets the instrument.
INIT:CONT OFF
//Turns on single sweep mode.
CALC:MARK:FUNC:HARM ON
//Turns on the harmonic distortion measurement.
CALC:MARK:FUNC:HARM:NHAR 3
//Defines three harmonics to be found.
CALC:MARK:FUNC:HARM:BAND:AUTO OFF
//Turns off automatic bandwidth selection.
CALC:MARK:FUNC:HARM:PRES
//Determines the ideal configuration.
//-------------Performing the Measurement-------------------
INIT;*WAI
//Initiates the measurement and finishes the sweep.
//-------------Retrieving the Results------------------------
CALC:MARK:FUNC:HARM:LIST?
//Queries the position of the harmonics.
CALC:MARK:FUNC:HARM:DIST? TOT
//Queries the total harmonic distortion.
