[:SENSe]:FREQuency:IQ:CENTer?
Example
:FREQ:IQ:CENT 30 MHz
Notes This command is the same in all Modes, but the parameter is Measurement Global, so the value is
independent in each Mode and common across all the measurements in the Mode
Preset 0 Hz
State Saved Saved in instrument state
Min/Max –/+40.049995 MHz
CF Step
Changes the step size for the "Center Frequency" on page 1128 and start and stop
frequency functions. Once a step size has been selected and the center frequency
function is active, the step keys (and the UP|DOWN parameters for Center Frequency
from remote commands) change the center frequency by the step-size value. The
step size function is useful for finding harmonics and sidebands beyond the current
frequency span of the instrument.
Note that the start and stop frequencies also step by the CF Step value.
Remote Command
[:SENSe]:FREQuency:CENTer:STEP[:INCRement] <freq>
[:SENSe]:FREQuency:CENTer:STEP[:INCRement]?
Example Increase the current center frequency value by 500 MHz:
:FREQ:CENT:STEP 500 MHz
:FREQ:CENT UP
:FREQ:CENT:STEP?
Notes Preset and Max values are depending on Hardware Options
Dependencies Not available in the MSR, LTEAFDD, LTEATDD, 5GNR, and Channel Quality Modes
If the electronic/soft attenuator is enabled, any attempt to change the value of the center frequency
>3.6 GHz by pressing the Up-Arrow key, fails and results in an advisory message. If the equivalent
SCPI command is sent, this same message is generated as part of a “-221, Settings conflict” warning
Couplings When auto-coupled, the center frequency step size is set to 10% of the span
Preset Auto

Min/Max –/+ (the maximum frequency of the instrument). That is, 27 GHz max freq instrument has a CF step
range of +/- 27 GHz. Note that this is the maximum frequency given the current settings of the
instrument, so in External Mixing, for example, it is the maximum frequency of the current mixer band
