[SENSe:]FREQuency:CENTer <Frequency>
This command defines the center frequency of the R&S FPC.
In the spectrum application, the command also defines the frequency for time domain
measurements (span = 0).
Parameters:
<Frequency> <numeric value>
Refer to the datasheet for details on the frequency range of your
R&S FPC.
*RST: fmax/2 with fmax = maximum frequency
Default unit: Hz
Example: //Define center frequency
FREQ:CENT 100MHZ
[SENSe:]FREQuency:CENTer:STEP
<StepSize>
This command defines the center frequency step size.
Prerequisites for this command
●
Turn off step size coupling ([SENSe:]FREQuency:CENTer:STEP:LINK).
Parameters:
<StepSize> <numeric value>
Range: 1 Hz to fmax
*RST: – (AUTO 0.1*SPAN is switched on)
Default unit: Hz
Example: //Define a CF step size
FREQ:CENT:STEP:LINK OFF
FREQ:CENT:STEP 10MHZ
[SENSe:]FREQuency:CENTer:STEP:LINK <StepSizeCoupling>
This command selects the center frequency step size mode.
For time domain measurements, the command couples the step size to the resolution
bandwidth.
Parameters:
<StepSizeCoupling> CENTer
Step size equals the current center frequency.
DIVTen
Couple the step size to the span (10 %).
OFF
Turn off the coupling (manual step size).
You can define a manual step size with [SENSe:]FREQuency:
CENTer:STEP.
*RST: DIVTen
