Spacing
In "RF and LF Frequency Sweep" mode, "Spacing " selects the mode for calculating
the frequency interval, which increases or decreases the current frequency at each
step.
To determine the step size, select the parameter Step Linear/Step Logarithmic.
In "RF Combined Sweep" mode, the parameter indicates that the step intervals are lin-
early (straight proportional) distributed, i.e. the intervals have the same size. The fre-
quency / level range and the Dwell Time time determine the calculated step size.
"Linear"
Takes the frequency value entered as absolute value in Hz.
"Logarithmic"
Takes the value entered as a logarithmic value, i.e. as a constant
fraction of the current frequency in %.

RF combined sweep: n.a.
LF frequency sweep:

Dwell Time
Defines the duration of the individual sweep steps.
Note: In case of considerable overrun conditions, the R&S SMB100B turns off the
sweep mode.

Trigger Slope
For "Mode = Extern Step/Single", selects the polarity of the active slope of an applied
instrument trigger.
Trigger signal is expected at the Inst Trig connector.
"Positive"
The rising edge of the trigger signal triggers the instrument.
"Negative"
The falling edge of the trigger signal triggers the instrument.
