Start Frequency/Stop Frequency
Defines the frequency sweep range by setting the start and end values.
See Chapter 6.2.1, "Correlating parameters in sweep mode", on page 122.
Remote command:
RF frequency sweep:
[:SOURce<hw>]:FREQuency:STARt on page 458
[:SOURce<hw>]:FREQuency:STOP on page 459
RF combined sweep:
[:SOURce<hw>]:COMBined:FREQuency:STARt on page 513
[:SOURce<hw>]:COMBined:FREQuency:STOP on page 514
LF frequency sweep:
[:SOURce<hw>]:LFOutput:FREQuency:STARt on page 466
[:SOURce<hw>]:LFOutput:FREQuency:STOP on page 466
Center Frequency
In "RF Frequency Sweep" mode, sets the RF center frequency.
See Chapter 6.2.1, "Correlating parameters in sweep mode", on page 122.
Remote command:
[:SOURce<hw>]:FREQuency:CENTer on page 458
Span
In "RF Frequency Sweep" mode, sets the span of the frequency sweep range.
See Chapter 6.2.1, "Correlating parameters in sweep mode", on page 122.
Remote command:
[:SOURce<hw>]:FREQuency:SPAN on page 458
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 %.
