[SENSe:]FREQuency:CENTer
<CenterFrequency>
This command defines the center frequency of the R&S
ZNH.
In spectrum analyzer mode, the command also defines the measuring frequency for
time domain measurements (span
=
0).
Parameters:
<CenterFrequency> Range:
Depends on the operating mode and is specified in
the data sheet.
*RST:
fmax /2 with fmax = maximum frequency
Default unit: MHz
Example:
FREQ:CENT 100MHz
Defines a center frequency of 100 MHz.
[SENSe:]FREQuency:CENTer:STEP
<Stepsize>
This command defines the center frequency step size.
Parameters:
<Stepsize>
Range:
1 Hz to fmax
*RST:
- (AUTO 0.1*SPAN is switched on)
Default unit: MHz
Example:
FREQ:CENT:STEP 120MHz
Defines a CF step size of 120 MHz.
[SENSe:]FREQuency:CENTer:STEP:LINK
<CouplingState>
This command couples and decouples the center frequency step size to the span.
For time domain measurements, the command couples the step size to the resolution
bandwidth.
Parameters:
<CouplingState>
CENTerf | DIVTen | OFF
CENTerf
Sets the step size equal to the center frequency.
DIVTen
Couples the step size to the span (10 %).
OFF
Turns off the coupling (manual step size).
*RST:
DIVTen
Example:
FREQ:CENT:STEP:LINK DIVT
Couples the step size to 10% of the span.
[SENSe:]FREQuency:SPAN
<FrequencySpan>
This command defines the frequency span.
