Comments The available default units are:
DBM | DBMW: dB referenced to 1 milliwatt.
V: Volts. This is equivalent to VPK for time-varying waveforms.
VPK: Volts peak
VPP: Volts peak-to-peak
VRMS: Volts RMS
W: Watts
For W, DBM, and DBMW, the amplitude is referenced to the
OUTPut[1]:LOAD
value; they are meaningless and therefore unavailable if OUTPut[1]:LOAD INFinity
is set.
Executable when Initiated: Yes
Coupling Group: None
