READ Subsystem
Remarks: The first value (for the fundamental) is measured in
dBm; the remaining harmonics are measured in dBc. If
fewer than ten harmonics are measured, zero is
returned for any harmonic not measured. The
harmonic amplitude precision for SCPI and the display
is two decimal places.

Return Harmonic N Amplitude

:READ:HARMonics:AMPLitude[n]?
Returns the amplitude of harmonic number n, measured in dBc from
the fundamental, or in dBm if n=1.
Range: –180 dBm to 70 dBm
Default Unit: dBc (from fundamental); dBm (n=1)
Remarks: The harmonic amplitude precision for SCPI and the
display is two decimal places.

Return % Total Harmonic Distortion

:READ:HARMonics[:DISTortion]?
Returns the computed total harmonic distortion as a percentage.
Range: 0 to float64
Default Unit: %
Remarks: The total harmonic distortion precision for SCPI and
the display is three significant digits.
