"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.
"High Dyn. Uninterrupted"
R&S SMAB-K724
Provides a linear output power that is uninterrupted over a wide
dynamic range.
"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 on page 631
Mode
Allows you to optimize the RF output signal for applications, where improved harmonic
distortion or improved wideband noise is required.
"Normal"
Generates an RF output signal with high signal to noise ratio as well
as low distortion, according to the data sheet.
"Low Noise"
Optimizes the signal to noise ratio.
"Low Distortion"
Reduces distortion (harmonics) of the RF signal to a minimum.
Remote command:
[:SOURce<hw>]:POWer:LMODe on page 632
Harmonic Filter
Activates low harmonic filter or enables its automatic switching.
"On"
Ensures best low harmonics performance but decreases the level
range.
"Auto"
Applies an automatically selected harmonic filter that fits to the cur-
rent level setting.
Remote command:
:OUTPut<hw>:FILTer:MODE on page 446
Level Range
Shows the interruption-free range of the level that you can use in the currently selected
mode.
