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

Measurement results (formats other than FSK)
I-Q measured Time, spectrum (filtered, carrier locked,
symbol locked)
I-Q reference Time, spectrum (ideal, computed from
detected symbols)
I-Q error versus time results Magnitude, phase (I-Q measured versus reference)
Error vector Time, spectrum
(vector difference between measured and reference)
Symbol table and error summary Error vector magnitude is computed at symbol

The following trace formats are available for
measured data and computed ideal reference data,
with complete marker and scaling capabilities, and
automatic grid line adjustment to ideal symbol or
constellation states.
