Command
[:SENSe]:FREQuency:CENTer <freq>
[:SENSe]:FREQuency:CENTer?
Example Set Center Frequency to 50 MHz:
:FREQ:CENT 50 MHz
Increment 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 it is equivalent to :FREQ:RF:CENT
–
For I/Q input it is equivalent to :FREQ:IQ:CENT
–
For External Mixer it is equivalent to :FREQ:EMIX:CENT
Preset and Max values are dependent 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
Preset Depends on instrument maximum frequency, mode, measurement, and selected input
See "Center Frequency Presets" on page 1130, "RF Center Freq" on page 1132, "Ext Mix Center Freq"
on page 1133, "I/Q Center Freq" on page 1133, and "VXT Models with Radio Heads/CIU Frequency
Range" on page 1132
State Saved Saved in instrument state
Min/Max Depends on instrument maximum frequency, mode, measurement, and selected input
See "Center Frequency Presets" on page 1130, "RF Center Freq" on page 1132, "I/Q Center Freq" on
page 1133, and "VXT Models with Radio Heads/CIU Frequency Range" on page 1132
