Range

Default

<value> Real 9kHz to 3GHz 100MHz

Explanation  When <value> is set in "Number" form, the default unit is Hz. Besides, <value>

can also be set in "Number + Unit" form; for example, 4MHz.

 After the start frequency is set, you can rotate the knob to modify the start

frequency at the current step. At this point, you can query or set the current step

using the [:SOURce]:SWEep:STEP:STARt:FREQuency:STEP command.

Return Format The query returns the start frequency of the sweep. For example, 4.00000000MHz.

Example

:SWE:STEP:STAR:FREQ 4MHz

:SWE:STEP:STAR:FREQ?
