Start Level / Stop Level
Defines the RF level sweep range by setting the start and end values.
See Chapter 6.2.1, "Correlating Parameters in Sweep Mode", on page 164.
Remote command:
[:SOURce<hw>]:POWer:STARt on page 634
[:SOURce<hw>]:POWer:STOP on page 634
Spacing
Indicates that the level step intervals are linearly (straight proportional) distributed, i.e.
intervals are of equal size.
Set the step size with the parameter "Step".
Remote command:
n.a.
Step
Applies to "RF Level Sweep" mode.
Sets the step width for the RF level sweep steps logarithmically in dB.
Remote command:
[:SOURce<hw>]:SWEep:POWer:STEP[:LOGarithmic] on page 647
Setting Characteristics
Selects additional quality characteristics to optimize the behavior of the RF signal level
for the corresponding 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.
