[SENSe:]FREQuency:CENTer:STEP:AUTO <State>
This command couples or decouples the center frequency step size to the span.
In time domain (zero span) measurements, the center frequency is coupled to the
RBW.
Parameters:
<State> ON | OFF | 0 | 1
*RST: 1
Example:
FREQ:CENT:STEP:AUTO ON
Activates the coupling of the step size to the span.
[SENSe:]FREQuency:CENTer:STEP:LINK <CouplingType>
This command couples and decouples the center frequency step size to the span or
the resolution bandwidth.
Parameters:
<CouplingType> SPAN | RBW | OFF
SPAN
Couples the step size to the span. Available for measurements
in the frequency domain.
RBW
Couples the step size to the resolution bandwidth. Available for
measurements in the time domain.
