For "Envelope Voltage Reference > Vcc", sets the minimum and maximum values of
the supply voltage V

Example:
Envelope Voltage Reference = V
V Offset = 0 mV

V Max = 1 V = 0 dBV
cc
Gain = 3 dB
V Max [dBV] - Gain [dB] = V
cc
V Max = 0 dBV - 3 dB = -3 dBV = 0.708 V

Power Offset ← PA characteristics
Indicates an enabled power offset, for example to compensate power attenuation
because of cable lengths.
The displayed value is applied as level offset to the generated RF signal and considers
the following settings:
●
"RF > RF Level > Level > Offset"
●
"RF > RF Level > UCOR"
