:HARMonic[:UPPer] <NRf>
[:SENSe[1]]:DISTortion:HARMonic[:UPPer] <NRf> Set last harmonic included in measurement
Parameters <NRf> = 2 to 64 Set last harmonic
Query :HARMonic? Query last harmonic
Description This command controls the number of harmonics included in the distortion
calculation. The number of harmonics acts like a low-pass filter, allowing
only the second harmonic through harmonic <n> to affect the calculated
distortion.
The harmonics setting has no effect on THD+n or SINAD measurements,
and sending this command generates a -221 Settings Conflict Error. The
harmonic value may be queried, however.
:SFILter <name>
[:SENSe[1]]:DISTortion:SFILter <name> Select the shaping filter for distortion
calculation
Parameters <name> = NONE No filter, flat response
C C Message Weighting filter
CCITT CCITT filter
CCIRARM CCIR/ARM filter
A “A” Weighting filter
CCIR CCIR filter
Query :SFILter? Query filter choice
Description This command selects the shaping filter, if any, to apply to the measured
waveform.
