Amplitude - RF Signal
Sets the RF level of the RF output connector.
The level entered and displayed here corresponds to the level at the RF output, i.e. any
offset entry is not taken into consideration.
Note: The SCPI command SOUR:POW:LEV:IMM:AMPL sets the level of the "Level" dis-
play, i.e. the level containing offset.
SCPI command:
[:SOURce<hw>]:POWer[:LEVel][:IMMediate][:AMPLitude] on page 765
Limit - RF Signal
Sets the level limit.
The value specifies the upper limit of the level at the RF output connector. A message
appears if an attempt is made to set a level above this limit and the level at the RF output
is confined to the upper limit. However, the level indication is not influenced.
