Center Frequency
In "RF Frequency Sweep" mode, sets the RF center frequency.
See Chapter 8.7.2.1, "Correlating Parameters in Sweep Mode", on page 501.
Remote command:
[:SOURce<hw>]:FREQuency:CENTer on page 1131
Span
In "RF Frequency Sweep" mode, sets the span of the frequency sweep range.
See Chapter 8.7.2.1, "Correlating Parameters in Sweep Mode", on page 501.
Remote command:
[:SOURce<hw>]:FREQuency:SPAN on page 1131
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 %.
Remote command:
RF frequency sweep:
[:SOURce<hw>]:SWEep[:FREQuency]:SPACing on page 1211
RF combined sweep: n.a.
LF frequency sweep:
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:SPACing on page 1163
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.
