VXT Models with Radio Heads/CIU Frequency Range
The following table shows the Center Frequency Presets and Range for VXT modes
with Radio Heads/CIU.
Products with Radio Heads/CIU Preset Start frequency Stop frequency
M9421A + CIU 6 GHz 5.9 GHz 12 GHz
M9410A + CIU 6 GHz 5.9 GHz 12 GHz
M9410A + CIU + RRH 25 GHz 24.25 GHz 43.5 GHz
RF Center Freq (Remote Command Only)
Specifies the RF Center Frequency. Sets the Center Frequency to use when the RF
input is selected, even if the RF input is not the input that is selected at the time the
command is sent. Note that the Center Frequency function in the Frequency menu
on the front panel always applies to the currently selected input.
Remote Command
[:SENSe]:FREQuency:RF:CENTer <freq>
[:SENSe]:FREQuency:RF:CENTer?
Example
:FREQ:RF:CENT 30 MHz
:FREQ:RF:CENT?
Notes This command is the same in all Modes, but the parameter is Measurement Global. So, the value is
independent in each Mode and common across all the measurements in the Mode
Dependencies If the electronic/soft attenuator is enabled, any attempt to set Center Frequency such that the Stop
Frequency would be >3.6 GHz fails and results in an advisory message. If the equivalent SCPI
command is sent, this same message is generated as part of a “-221, Settings conflict” warning
Preset See table above
State Saved Saved in instrument state
Min -79.999995 MHz
Max See table above. Basically, instrument maximum frequency - 5 Hz
