Step - Level Sweep
Sets the step width for the individual sweep steps. This entry is effective for all sweep
modes.
With the level sweep, the logarithmic step width is a constant fraction of the current
level. This fraction is added to the current level. The logarithmic step width is entered in
dB.
Remote command:
[:SOURce<hw>]:SWEep:POWer:STEP[:LOGarithmic]

Dwell Time - Level Sweep
Enters the dwell time and determines the duration of the individual sweep steps.
The "Dwell Time" set by the user is used as the step time of the sweep. The effective

Note:
It is recommended to switch off the display update for optimum sweep performance
especially with short dwell times (see
Chapter 5.2.3.7, "Display Update" , on page 100).
