3 Short-Range Comms & IoT Mode
3.2 Modulation Analysis Measurement
modes are also able to share a Mode Global center frequency value. If this is the
case, the Mode will have a Global tab in its Meas Setup menu.
Remote
Command
[:SENSe]:FREQuency:CENTer <freq>
[:SENSe]:FREQuency:CENTer?
Example
:FREQ:CENT 50 MHz
:FREQ:CENT?
Preset 1 GHz
State Saved Saved in instrument state
Min -79.999995 MHz, unless the Source Mode is set to Tracking, in which case it is limited by the
minimum frequency of the Source
Max Basically, the instrument maximum frequency - 5 Hz. Note that, if the Source Mode is set to Tracking,
the effective instrument maximum frequency may be limited by the source maximum frequency
Status Bits/OPC
dependencies
Non-overlapped
CF Step
Changes the step size for the center frequency.
Remote Command
[:SENSe]:FREQuency:CENTer:STEP[:INCRement] <freq>
[:SENSe]:FREQuency:CENTer:STEP[:INCRement]?
[:SENSe]:FREQuency:CENTer:STEP:AUTO OFF | ON | 0 | 1
[:SENSe]:FREQuency:CENTer:STEP:AUTO?
Example
:FREQ:CENT:STEP 500 MHz
:FREQ:CENT UP
increases the current center frequency value by 500 MHz
:FREQ:CENT:STEP?
:FREQ:CENT:STEP:AUTO ON
:FREQ:CENT:STEP:AUTO?
Notes Preset and Max values are depending on Hardware Options (503, 507, 508, 513, 526)
Dependencies BW, Center frequency
If the electronic/soft attenuator is enabled, any attempt to change the value of the center frequency
>3.6 GHz by pressing the Up-arrow key, 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 Auto
State Saved Saved in instrument state
Min 1 Hz
Max The maximum frequency of the instrument
Status Bits/OPC
dependencies
non-overlapped
