Remote command:
:OUTPut<hw>:AFIXed:RANGe:LOWer? on page 887
:OUTPut<hw>:AFIXed:RANGe:UPPer? on page 887
Readjust
Recalculates and adjusts the internal switch positions of the RF chain according to the
current level.
In "Sample & Hold" or "Sample & On" mode, the function also triggers a new sample
process. During the recalculation, the output level is blanked briefly.
Remote command:
[:SOURce<hw>]:POWer:ALC:SONCe on page 1190
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 1193
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 SMW RF output is not changed.
See Chapter 8.4.4.1, "Displayed RF Frequency and Level Values with Downstream
Instruments", on page 472.
Remote command:
[:SOURce<hw>]:POWer[:LEVel][:IMMediate]:OFFSet on page 1196
User Variation
Defines and activates a user-defined step width for varying the RF frequency or RF
level with the rotary knob.
If disabled, the step width varies in steps of one unit at the cursor position.
Variation Active ← User Variation
Activates the set user-defined step width.
Remote command:
[:SOURce<hw>]:FREQuency:STEP:MODE on page 1132
