Radio Standard
A Radio Standard can used to integrate power within specific radio channels.
When a Radio Standard is selected, the Span setting is automatically coupled
to the defined Channel Width for that standard. (Width is the same for all
channels within a standard.) Also, Unit is set to Chan , and CF is set to the
nearest specific Channel defined in the standard.
