Description
The FB command specifies the stop frequency value. The stop frequency is equal to the center frequency plus the span divided by two (FB = CF + SP/2). Changing the stop 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 stop frequency. |
