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.
SCPI command:
[:SOURce<hw>]:SWEep:POWer:STEP[:LOGarithmic] on page 701
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 net
dwell time is shorter, reduced by the setting time. This setting time may be greater than
the time specified in the data sheet.
Note:
It is recommended to switch off the GUI update for optimum sweep performance espe-
cially with short dwell times (see chapter 5.2.3.5, "Gui Update", on page 115).
SCPI command:
[:SOURce<hw>]:SWEep:POWer:DWELl on page 698
