R&S FSQ Remote Control – Description of Commands
6.16.7 SENSe:FREQuency Subsystem
SENSe Subsystem
The SENSe:FREQuency subsystem defines the frequency axis of the active display. The frequency axis
can either be defined via the start/stop frequency or via the center frequency and span.
The measurement windows are selected by SENSe1 (screen A) and SENSe2 (screen B).
[SENSe:]FREQuency:CENTer 0 to fmax
This command defines the center frequency of the R&S FSQ or the measuring frequency for span = 0.
Example: "FREQ:CENT 100MHz"
Characteristics: *RST value: fmax /2 with fmax = maximum frequency
SCPI: conform
Mode: A
[SENSe:]FREQuency:CENTer:STEP 0 to fmax
This command defines the step width of the center frequency.
Example: "FREQ:CENT:STEP 120MHz"
Characteristics: *RST value: - (AUTO 0.1 × SPAN is switched on)
SCPI: conform
Mode: A
[SENSe:]FREQuency:CENTer:STEP:LINK SPAN | RBW | OFF
This command couples the step width of the center frequency to span (span >0) or to the resolution
bandwidth (span = 0) or cancels the couplings.
Parameter: SPAN = Coupling to frequency display range (for span > 0)
RBW = Coupling to resolution bandwidth (for span = 0)
OFF = manual input, no coupling.
Example: "FREQ:CENT:STEP:LINK SPAN"
Characteristics: *RST value: SPAN
SCPI: device-specific
Mode: A
[SENSe:]FREQuency:CENTer:STEP:LINK:FACTor 1 to 100 PCT
This command couples the step width of the center frequency with a factor to the span (span >0) or to
the resolution bandwidth (span = 0).
Example: "FREQ:CENT:STEP:LINK:FACT 20PCT"
Characteristics: *RST value: - (AUTO 0.1 × SPAN is switched on)
SCPI: device-specific
Mode: A
