MEASure:SIGNal:AMPL? {<phase = 0 | 1 | 2> }, {<unit = 0 | 1>} [,{<harmonic = 0-63>}]
Request for amplitude of defined harmonic of defined input signal.
Parameters: phase (0=L1, 1=L2, 2=L3), unit (0=U, 1=I) and harmonic number
Answer: amplitude of harmonic (all harmonics if last parameter omitted)
MEASure:SIGNal:PHASe? {<phase = 0 | 1 | 2> }, {<unit = 0 | 1>} [,{<harmonic = 0-63>}]
Request for phase of defined harmonic of defined input signal.
Parameters: phase (0=L1, 1=L2, 2=L3), unit (0=U, 1=I) and harmonic number
Answer: phase of harmonic (all harmonics if last parameter omitted)
MEASure:SIGNal:SAMPle? {<phase = 0 | 1 | 2> }, {<unit = 0 | 1>}
Request for raw samples of defined input signal.
Signal data are always actual - not influenced by next subcommand HOLD.
Parameters: phase (0=L1, 1=L2, 2=L3) and unit (0=U, 1=I)
Answer: raw samples of defined signal separated by spaces. Each sample is an integer value.
Quantity of these integers is equal to points of FFT (max. / typically 128).
MEASure:SIGNal:HOLD
Command for storing actual values of signals in all 6 measured channels into memory = holding data
actual in time of sending this command. This command influences only next command used for
reading amplitudes of holded samples. Reading values is not clearing or refreshing registers ... it
means new HOLD command has to be used for new data.
MEASure:SIGNal:AMPLitude? {<phase = 0 | 1 | 2> }, {<unit = 0 | 1>}
Request for amplitude of samples of defined input signal - holded in memory by HOLD command.
Parameters: phase (0=L1, 1=L2, 2=L3) and unit (0=U, 1=I)
Answer: samples of defined signal separated by spaces [in values Amperes or Volts].
Each sample is in exponential format: +#.#####E+##
Quantity of these samples is equal to points of FFT (max. / typically 128).

5.13.2 Harmonic Limitation

Harmonics Measurement Limitation system enables to limit calculation of measured values only from
defined number of harmonics.
Local configuration
Measurement / Harm. Meas Mode with possible values:
FUNDAMENTAL_ONLY, FIRST_X_HARMONICS, ALL_63_HARMONICS
Measurement / Harm. Meas Limit with possible values 2 - 63 (for 128 pt. FFT).
Remote interface commands
MEASure:HARM?
Request for harmonic measurement limitation system mode.
Answer:
0 = ALL_HARMONICS, 1 = FUNDAMENTAL_ONLY, 2 = FIRST_X_HARMONICS
MEASure:HARM {<mode=0-2>}
Setting of harmonic measurement limitation system mode.
Parameter: mode (
0 = ALL_HARMONICS, 1 = FUNDAMENTAL_ONLY, 2 = FIRST_X_HARMONICS)
MEASure:HARM:LIMit?
Request for user defined max. harmonic used for calculations.
Answer: harmonic number (2 - 63)
MEASure:HARM:LIMit {<X=2-63>}
Setting of user defined max. harmonic used for calculations.
Parameter: harmonic number (2 - 63)
