[SENSe:]FREQuency:CENTer <CenterFrequency>
This command defines the center frequency of the R&S Cable Rider ZPH.
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.
14.6.4.2 Defining the Vertical Axis
The following chapter describes command necessary to define the vertical scale such

CALCulate<1...2>:MARKer<1...6>:FUNCtion:LEVel:ONCE
This command adjusts the reference level to the measured signal power.
This automatic routine makes sure that the signal power level does not overload the
R&S Cable Rider ZPH or limits the dynamic range by too small an S/N ratio.
