Remote command:
[:SOURce]:POWer[:LEVel][:IMMediate][:AMPLitude]
Offset
Sets a level offset.
This value represents the level shift of a downstream instrument, as, for example, an
attenuator or an amplifier, and is indicated in the status bar of the display. It does not
change the level at the RF output.
Remote command:
[:SOURce]:POWer[:LEVel][:IMMediate]:OFFSet
Mode
Allows you to optimize the RF output signal for applications, where improved harmonic
distortion or improved wideband noise is required.
"Normal"
In normal mode, the generator provides an RF output signal with high
signal to noise ratio and low distortion, according to the data sheet.
"Low Noise"
This setting forces the generator to optimize the signal to noise ratio.
"Low Distortion"
In this mode, the generator reduces distortions of the RF signal to a
minimum.
Remote command:
Setting Characteristic
Selects the characteristic for the level setting. For some general applications, the
instrument operation can be optimized by choosing one of the predefined level setting
characteristics.
"Auto"
The instrument provides the highest dynamic range and the fastest
setting times according to the data sheet.
The RF signal is shortly blanked during the moment the step attenua-
tor is switched on.
"Uninterrupted Level setting"
Suppresses level blanking at frequency and level changes.
This mode reduces the dynamic range of the instrument. The step
attenuator is fixed.
"Strictly Monotone"
Provides level setting without discontinuities. All electronic switches in
the RF path are clamped. The operation mode is useful for applica-
tions using level searching algorithms.
This mode further reduces the dynamic range of the instrument.
"Constant-VSWR"
Suppresses output impedance variations at the [RF Out] connector
due to switching of the step attenuator. The step attenuator is fixed.
This mode reduces the dynamic range of the instrument.
