Maximum symbol rate

Symbol rate is limited only by the measurement

span; that is, the entire signal must fit within the

analyzer’s currently selected frequency span.

Example: with raised-cosine filtering

Max symbol rate*= frequency span

1 + α

*Maximum symbol rate doubled for VSB

modulation format

Measurement results (formats other than FSK)
