RF combined sweep:
[:SOURce<hw>]:COMBined:POWer:STARt on page 1214
[:SOURce<hw>]:COMBined:POWer:STOP on page 1214
Step Count
In "RF Combined Mode", defines the number of sweeps to be executed in Mode > Sin-
gle.
To start the sweep cycles, select Execute Single.
Remote command:
[:SOURce<hw>]:SWEep:COMBined:COUNt on page 1215
Spacing
Indicates that the instrument distributes the level steps linearly (straight proportional),
i.e. the level steps have the same size.
To determine the step size, use the parameter Step.
Remote command:
n.a.
Step
Sets the step width for the RF level sweep in dB.
The "RF level sweep" mode increases or decreases the level value linearly by the set
value.
Remote command:
[:SOURce<hw>]:SWEep:POWer:STEP[:LOGarithmic] on page 1210
Setting Characteristics
Selects additional quality characteristics to optimize the behavior of the RF signal level
for the specific application.
"Auto"
Sets the RF output level automatically according to the selected
mode.
In this mode, the instrument provides the highest dynamic range and
fastest setting times, as specified in the data sheet.
The RF signal is shortly blanked when the step attenuator is switch-
ing.
"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.
