Note
•
Center frequency and span settings automatically
change according to start and stop frequency settings,
and vice versa.
•
If the span becomes smaller than the CHBW (channel
bandwidth) in the ACPR or OCBW measurement
(page82), the warning “Span is less than CHBW!”
appears in the command window.
