Remote Command
[:SENSe]:FREQuency:CENTer <freq>
[:SENSe]:FREQuency:CENTer?
Example Set Center Frequency to 50 MHz:
:FREQ:CENT 50 MHz
Increment the Center Frequency by the value of CF Step:
:FREQ:CENT UP
Return the current value of Center Frequency:
:FREQ:CENT?
Notes Sets the RF, External Mixing or I/Q Center Frequency depending on the selected input:
–
For RF input, equivalent to :FREQ:RF:CENT
–
For I/Q input, equivalent to :FREQ:IQ:CENT
–
For External Mixer, equivalent to :FREQ:EMIX:CENT
Preset and Max values depend on Hardware Options
If no terminator (for example, MHz) is sent, the terminator Hz is used. If a terminator with unit other
than frequency is used, an invalid suffix error message is generated
Dependencies Not available in MSR, LTE-Advanced FDD/TDD and 5G NR Modes
Preset Depends on instrument maximum frequency, mode, measurement, and selected input
See "Center Frequency Presets" on page 254 and "RF Center Freq" on page 256 and "Ext Mix Center
Freq" on page 257 and "I/Q Center Freq" on page 258 and "VXT Models with Radio Heads/CIU
Frequency Range" on page 256
State Saved Saved in instrument state
Min/Max Depends on instrument maximum frequency, mode, measurement, and selected input
See "Center Frequency Presets" on page 254 and "RF Center Freq" on page 256 and "I/Q Center
Freq" on page 258 and "VXT Models with Radio Heads/CIU Frequency Range" on page 256
