3 Short-Range Comms & IoT Mode
3.7 ACP Measurement
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 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
Dependencies Not available in the MSR, LTEAFDD, LTEATDD and 5G NR Modes
Preset Depends on instrument maximum frequency, mode, measurement, and selected input
See "Center Frequency Presets" on page 845, "RF Center Freq" on page 847, "Ext Mix Center Freq" on
page 848, "I/Q Center Freq" on page 849 and "VXT Models with Radio Heads/CIU Frequency Range"
on page 847
State Saved Saved in instrument state
Min/Max Depends on instrument maximum frequency, mode, measurement, and selected input
See "Center Frequency Presets" on page 845, "RF Center Freq" on page 847, "I/Q Center Freq" on
page 849 and "VXT Models with Radio Heads/CIU Frequency Range" on page 847
Annotation Center <value> appears in the lower left corner of the display
