3.5 Channel Power Measurement
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 610 and "RF Center Freq" on page 612 and "Ext Mix Center
Freq" on page 613 and "I/Q Center Freq" on page 614 and "VXT Models with Radio Heads/CIU
Frequency Range" on page 612
State Saved Saved in instrument state
Min/Max Depends on instrument maximum frequency, mode, measurement, and selected input
See "Center Frequency Presets" on page 610 and "RF Center Freq" on page 612 and "I/Q Center
Freq" on page 614 and "VXT Models with Radio Heads/CIU Frequency Range" on page 612
