[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
Default unit: PCT
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 445
[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 446.
Note: In MSRA/MSRT mode, the setting command is only available for the MSRA/
MSRT Master. For MSRA/MSRT slave applications, only the query command is availa-
ble.
Parameters:
<Offset> Range: -1 THz to 1 THz
*RST: 0 Hz
Default unit: HZ
Example:
FREQ:OFFS 1GHZ
Manual operation: See "Frequency Offset" on page 446
[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 FSW starts a measure-
ment 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
Default unit: Hz
