CALCulate<1|2>:MARKer<1...4>:FUNCtion:HARMonics:LIST?
This command reads out the list of harmonics. The first value is the absolute power of the first
harmonic in the unit set via UNIT. The other values are relative to the carrier signal and are output
in dB.
The numeric values are output, separated by commas. The number corresponds to that of the
harmonics to be measured, which are defined with
CALC:MARK:FUNC:HARM:NHARM
.
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:LIST?"
’Outputs the three measured harmonics, separated by commas.
