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 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
Preset Depends on instrument maximum frequency, mode, measurement, and selected input
See "Center Frequency Presets" on page 1808, "RF Center Freq (Remote Command Only)" on page
1810, "Ext Mix Center Freq (Remote Command Only)" on page 1810, "I/Q Center Freq (Remote
Command Only)" on page 1811 and "VXT Models with Radio Heads/CIU Frequency Range" on page

State Saved Saved in instrument state
Min/Max Depends on instrument minimum/maximum frequency, mode, measurement, and selected input
