"Uninterrupted"
Suppresses blanking at level transitions. Frequency transitions can
lead to an RF level blanking due to hardware specific switching
points.
This mode reduces the dynamic range of the instrument. The step
attenuator is fixed.
Note:
Do not use the mode "I/Q Modulator > Optimization Mode > High
Quality" in combination with the modes "RF Level > Setting Charac-
teristics > Uninterrupted/Strictly Monotone".
The high quality I/Q optimization leads to RF signal interruption. The
requirements of the RF level modes "Uninterrupted" and "Strictly
Monotone" can not be fulfilled.
"Strictly Monotone"
Executes signal level changes monotonically increasing or decreas-
ing.
The setting makes sure that increasing the level value exclusively
results in an increased output level, and vice versa.
All electronic switches, which might affect the monotonicity are fixed.
The operation mode is useful for applications using level searching
algorithms which rely on a strictly monotonous behavior.
"Constant-VSWR"
Suppresses output impedance variations at the RF output connector,
due to changed level settings.
"User"
Indicates that a setting has been modified in the expert mode. The
expert mode is a protected function, that requires protection level 2
password.
Remote command:
[:SOURce<hw>]:POWer:LBEHaviour
Level Range
Shows the interruption-free range of the level that you can use in the currently selected
mode.
Remote command:
[:SOURce<hw>]:POWer:RANGe:LOWer?
[:SOURce<hw>]:POWer:RANGe:UPPer?

List Mode Settings
The "List Mode" dialog contains all the functions and settings for creating and handling
lists with RF frequency/level pairs for generating the RF signal based on these values.
Access:
► Select "RF" > "Sweep/List" > "List mode".
The dialog contains parameters for configuring the list mode processing, entering
list mode data and transferring data files from or to the instrument.
