Span
In "RF Frequency Sweep" mode, sets the span of the frequency sweep range.
See Chapter 7.2.1, "Correlating parameters in sweep mode", on page 181.
Remote command:
[:SOURce<hw>]:FREQuency:SPAN on page 647
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.
In "RF Frequency Sweep" mode and Sweep Type > Ramp, the parameter automati-
cally distributes the step intervals linearly.
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"
The spacing depends on the selected sweep type.
●
Sweep Type > Step
Takes the frequency value entered as absolute value in Hz.
●
Option: R&S SMAB-B28
Sweep Type > Ramp
Generates a synthesized continuous analog frequency sweep for
the duration set with the parameter Sweep Time.
"Logarithmic"
(Sweep Type > Step only)
Takes the value entered as a logarithmic value, i.e. as a constant
fraction of the current frequency in %.
Remote command:
RF frequency sweep:
[:SOURce<hw>]:SWEep[:FREQuency]:SPACing on page 704
RF combined sweep: n.a.
LF frequency sweep:
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:SPACing on page 664
Step Linear/Step Logarithmic
In "RF/LF Frequency Sweep" mode, sets the step width for the individual frequency
sweep steps. The value is added at each sweep step to the current frequency.
Depending on the current Spacing, you can enter either an absolute or logarithmic step
width.
This parameter is only available for Sweep Type > Step.
See Chapter 7.2.1, "Correlating parameters in sweep mode", on page 181.
"Step Linear"
The step width is a constant value in Hz.
