:FREQuency:CENTer
Supported All Models
[:SOURce]:FREQuency:CENTer <num>[<freq_suffix>]|UP|DOWN
[:SOURce]:FREQuency:CENTer? [MAXimum|MINimum]
This command sets the center frequency for a step sweep. The center frequency symmetrically divides
the selected frequency span and is coupled to the start and stop frequency settings. The frequency
range and reset values are dependent on the signal generator model and option number.
The query returns the start and stop frequencies if the optional MAXimum or MINimum are used.
Example
:FREQ:CENT .5 GHz
The preceding example sets the center frequency for a sweep to .5 GHz.

[:SOURce]:FREQuency:CHANnels:BAND?
This command sets the frequency of the signal generator by specifying a frequency channel band. The
frequency channel state must be enabled for this command to work. See
“:FREQuency:CHANnels[:STATe]” on page 35.
