The display is disabled when list mode is running, see Chapter 7, "List and sweep
mode", on page 171.
Remote command:
[:SOURce<hw>]:POWer:POWer on page 687
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 686
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 SMA100B RF output is not
changed.
See "RF frequency and level display with a downstream instrument" on page 66.
Remote command:
[:SOURce<hw>]:POWer[:LEVel][:IMMediate]:OFFSet on page 689
Setting Characteristics
Selects additional quality characteristics to optimize the behavior of the RF signal level
for the specific application.
"Auto"
Sets the RF output level automatically according to the selected
mode.
In this mode, the instrument provides the highest dynamic range and
fastest setting times, as specified in the data sheet.
The RF signal is shortly blanked when the step attenuator is switch-
ing.
