User Manual 1321.0950.02 ─ 07

[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
as the x-axis deviation per division and settings affecting the amplitude of the measure-
ments.

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.
