SENSe:FREQuency Subsystem R&S ESCI
1166.6004.12 6.168 E-1
SENSe:FREQuency 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<1|2>:]FREQuency:CENTer 0 to f
max
This command defines the receiver frequency or the center frequency in analyzer mode.
Example: "FREQ:CENT 100MHz"
Characteristics: *RST value: f
max
/2 with f
max
= maximum frequency
SCPI: conforming
Mode: all
[SENSe<1|2>:]FREQuency:CENTer:STEP 0 to f
max
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: conforming
Mode: all
[SENSe<1|2>:]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.
Parameters:
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
