Basic Function Commands
Frequency Subsystem ([:SOURce])
[:SOURce]:FREQuency:SPAN? [MAXimum|MINimum]
This command sets the length of the frequency range for a step sweep. Span setting is symmetrically
divided by the selected center frequency and is coupled to the start and stop frequency settings. The
span range is dependent on the signal generator model and option number.
Example
:FREQ:SPAN 100MHz
The preceding example sets the frequency span to 100 megahertz.
*RST 0.0000000000000E00

:FREQuency:STARt
Supported All Models
[:SOURce]:FREQuency:STARt <value><unit>
[:SOURce]:FREQuency:STARt?
This command sets the first frequency point in a step sweep.
*RST The preset value is model/option dependent. Refer to the instrument’s Data Sheet.
Range The range is model/option dependent. Refer to the instrument’s Data Sheet.
