Description
The FA command specifies the start frequency value. The start frequency is equal to the center
frequency minus (the span divided by two) (FA = CF − SP/2). Changing the start frequency changes the
center frequency and span.
NOTE The OA parameter only returns the current value to the controller. It does not set
the active function to the start frequency.
