R&S ESU
Example:
"CALC:MARK:FUNC:HARM:BAND:AUTO OFF"
'Switches automatic bandwidth expansion off.
Characteristics: *RST value: ON
SCPI: device-specific
Mode: A-F, A-T
CALCulate<1|2>:MARKer<1...4>:FUNCtion:HARMonics:PRESet
This command optimizes the device settings depending on the mode in which the harmonic
measurement was started:
If the harmonic measurement was started in the frequency domain (span > 0), the frequency and the
level of the first harmonic are calculated, from which the measurement list is set up.
If the measurement was started in the time domain (span = 0), the frequency of the first harmonic is
not changed. The level, however, is not calculated.
The function is independent of the marker selection, i.e. the suffix <1|2> or <1...4> of CALCulate
or MARKer is irrelevant.
Example:
"CALC:MARK:FUNC:HARM:PRES"
'Optimizes the device setting for the measurement of harmonics.
Characteristics: *RST value: --
SCPI: device-specific
This command is an event and therefore has no *RST value and no query.
Mode: A-F, A-T
CALCulate<1|2>:MARKer<1...4>:FUNCtion:HARMonics:DISTortion? TOTal
This command queries the results of the total harmonic distortion (THD).
A complete sweep with synchronization to sweep end should be performed between switching on the
function and querying the measured value to obtain a valid query result. This is only possible in the
single-sweep mode.
The function is independent of the marker selection, i.e. the suffix <1|2> or <1...4> of CALCulate
or MARKer is irrelevant.
Example:
"INIT:CONT OFF"
'Switches to single-sweep mode.
"CALC:MARK:FUNC:HARM:NHARM 3"
'Sets the number of harmonics to 3.
"CALC:MARK:FUNC:HARM ON"
'Switches on the measurement of harmonics.
"INIT;*WAI"
'Starts a sweep and waits for the end.
"CALC:MARK:FUNC:HARM:DIST? TOT"
'Outputs the total harmonic distortion in % and dB.
Characteristics: *RST value: --
SCPI: device-specific
Mode: A-F, A-T
