7.12.4 SOURce:FREQuency Subsystem
This subsystem contains the commands used to define the frequency settings for the RF
sources and sweeps.

[:SOURce<hw>]:FREQuency:CENTer <Center>
The command sets the center frequency of the sweep. This setting in combination with
the span setting ([SOURce:]FREQuency:SPAN) defines the sweep range.
This command is linked to the commands [SOURce:]FREQuency:STARt and
[SOURce:]FREQuency:STOP, i.e. changing these values causes the CENTer value to
change, and vice versa:
CENTer = (STARt + STOP)/2
As with the "Frequency" value entered in the header, the OFFSet value is also taken into
consideration with this command. The specified value range is therefore only effective if
OFFSet is set to 0. The value range for other OFFset values can be calculated using
the following formula:
300 kHz + OFFSet ... RF
max
+OFFSet
Parameters:
<Center> float
Range: RFmin to RFmax (depending on model)
Increment: 0.01Hz
*RST: 300MHz
Default unit: Hz
