The value is not affected by an instrument preset (PRESET key), *RST and the "Save/
Recall" function. This parameter is influenced only by the Factory Preset and its factory
value is equal to the upper limit.
SCPI command:
[:SOURce<hw>]:POWer:LIMit[:AMPLitude] on page 767
Offset (Level) - RF Signal
Sets the level offset relative to the RF level.
The level offset of a downstream instrument (e.g. 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 corre-
sponds to the level at the output of the downstream instrument.
SCPI command:
[:SOURce<hw>]:POWer[:LEVel][:IMMediate]:OFFSet on page 766
Attenuator Settings
The attenuator mode is set in the Attenuator Settings section.
Attenuator Mode - RF Signal
Sets the attenuator mode at the RF output.
The selection of Normal and High Power is only available when the instrument is equip-
ped with the high-power output option (R&S SMU-B31 or R&S SMU-B36).
"Auto"
Standard mode.
The electronically switching attenuator switches with a 5 dB step width
at fixed switching points.
With high-power output option: The entire level range is available. The
level settings are made in the area of the electronically switching attenu-
ator as well as the relay-switched option (longer switchover time, wear).
"Normal"
(Option High Power only)
The level settings are made only in the area of the electronically switching
attenuator. The high level ranges are not available.
This setting is wear-free, as the relays are not switched.
"High Power"
(Option High Power only)
The level settings are made only in the area of the high-power bypass.
Only the high level range is available. The relays are not switched.
