Example: //Couple step size to span
FREQ:CENT:STEP:LINK SPAN
Manual operation: See " Center Frequency Stepsize " on page 378
[SENSe:]FREQuency:CENTer:STEP:LINK:FACTor <Factor>
This command defines a step size factor if the center frequency step size is coupled to
the span or the resolution bandwidth.
Parameters:
<Factor> 1 to 100 PCT
*RST: 10
Example: //Couple frequency step size to span and define a step size fac-
tor
FREQ:CENT:STEP:LINK SPAN
FREQ:CENT:STEP:LINK:FACT 20PCT
Manual operation: See " Center Frequency Stepsize " on page 378
[SENSe:]FREQuency:OFFSet <Offset>
This command defines a frequency offset.
If this value is not 0 Hz, the application assumes that the input signal was frequency
shifted outside the application. All results of type "frequency" will be corrected for this
shift numerically by the application.
See also " Frequency Offset " on page 379.
Parameters:
<Offset> Range: -100 GHz to 100 GHz
*RST: 0 Hz
Example:
FREQ:OFFS 1GHZ
Manual operation: See " Frequency Offset " on page 379
[SENSe:]FREQuency:SPAN <Span>
This command defines the frequency span.
If you set a span of 0 Hz in the Spectrum application, the R&S FPL1000 starts a mea-
surement in the time domain.
Parameters:
<Span> The minimum span for measurements in the frequency domain
is 10 Hz.
For SEM and spurious emission measurements, the minimum
span is 20 Hz.
Range: 0 Hz to fmax
*RST: Full span
