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.
