R&S SMA100B - Harmonic Filter; Level Range

77User Manual 1178.3834.02 ─ 09
"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.
"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.
Note: The R&S SMA100B supports this characteristic at frequencies
above 52 MHz. If you select the setting at lower frequencies
(≤52 MHz), the instrument reports a settings conflict.
"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.

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.

Level Range
Shows the interruption-free range of the level that you can use in the currently selected
mode.
