"Step Lin" or "Step Log" is displayed depending on whether "Spacing Lin" or "Log" is
selected.
"Step Lin"
With the linear sweep, the step width is a fixed frequency value which
is added to the current frequency. The linear step width is entered in
Hz.
SCPI command:
[:SOURce]:LFOutput:SWEep[:FREQuency]:STEP[:LINear] on page 654
"Step Log"
With the logarithmic sweep, the step width is a constant fraction of the
current frequency. This fraction is added to the current frequency. The
logarithmic step width is entered in %.
SCPI command:
[:SOURce]:LFOutput:SWEep[:FREQuency]:STEP:LOGarithmic on page 654
Dwell Time - LF Sweep
Sets the dwell time. The dwell time 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]:LFOutput:SWEep[:FREQuency]:DWELl on page 651
Trigger Input Slope
Sets the polarity of the active slope of an applied instrument trigger.
This setting affects the INST TRIG input (BNC connector at the rear of the instrument).
"Positive"
The rising edge of the trigger signal is active.
"Negative"
The falling edge of the trigger signal is active.
