The display has been disabled for security reasons, see Annotation Frequency and
Annotation Amplitude .

The display is disabled when list mode is running, see " State - List Mode "

Remote command:
[:SOURce<hw>]:POWer:POWer
on page 529
Note: The SCPI command
[:SOURce<hw>]:POWer[:LEVel][:IMMediate][:
AMPLitude]
sets the level of the "Level" display, that is the level containing offset.
Limit - RF Level
Sets an upper limit for the RF output power.
You can use it to protect your DUT from damage due to high input power. If you enter
an RF level above this value, the instrument limits the output power to this specified
value, and generates a warning message.
However, the level indication in the status bar is not affected.
Note: The limit value is always effective, regardless of whether you work with "NRP-Z
Power Control" or not.
The value is not affected by an instrument preset (PRESET key),
*RST
and the "Save/
Recall" function. It is influenced only by the Factory Preset and the factory value is
equal to maximum level.
Remote command:
[:SOURce<hw>]:POWer:LIMit[:AMPLitude]
on page 527
Offset (Level)
Sets the level offset relative to the RF level.
The level offset of a downstream instrument (for example an attenuator or amplifier) is
entered.
The entry does not change the value of the RF level at the RF output. It only changes
the RF level displayed in the display header. The value of the RF level in the header
corresponds to the level at the output of the downstream instrument.
Remote command:
[:SOURce<hw>]:POWer[:LEVel][:IMMediate]:OFFSet

Power Resolution
Selects the resolution for the level settings.
