The value is offset-free and corresponds to the level at the RF connector.
See "RF frequency and level display with a downstream instrument" on page 296.
Note: Suppressed values in the status bar
For security concerns or certain operating modes, you can hide the frequency and
level display in the status bar.
●
The display has been disabled for security reasons.
See:
–
Annotation Frequency
– Annotation Amplitude
The display is disabled when:
–
List mode is running, see Chapter 7.10, "Varying the RF signal in list or sweep
mode" , on page 319.
Remote command:
[:SOURce<hw>]:POWer:POWer
on page 940
Note: The SCPI command
[:SOURce<hw>]:POWer[:LEVel][:IMMediate][:
AMPLitude]
sets the level of the "Level" display.
This means, the level containing offset.
Limit
Sets an upper limit for the RF output power.
You can use this value 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 the warning message:
"Pep value greater than the defined limit." However, the level indication in the status
bar is not affected.
The setting is not affected by an instrument preset ([Preset] key or
*RST
) and the
"Save/Recall" function. It is reset only by factory preset.
Remote command:
[:SOURce<hw>]:POWer:LIMit[:AMPLitude]
on page 938
Offset
Sets a level offset.
This value represents the level shift of a downstream instrument, like, for example, an
attenuator or an amplifier.
The "Level" value displayed in the status bar is the resulting level, as it is at the output
of the downstream instrument. The level at the R&S
SMM100A RF output is not
changed.
See "RF frequency and level display with a downstream instrument" on page 296.
Remote command:
[:SOURce<hw>]:POWer[:LEVel][:IMMediate]:OFFSet
