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] on page 428
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 display update for optimum sweep performance
especially with short dwell times (see Chapter 5.2.3.7, "Display Update", on page 100).
