The signal can be analyzed while being acquired or afterwards in
reanalysis mode. The following tools are available.

Burst averaging (see Using Averaging to Improve Results on page 70).

Measurement windows:

Data – time range defined as percentages of the symbol period, as
explained in Distinguishing Data Points from Transitions on
page 62.

Amplitude – intensity range defined as percentages of the eye
amplitude, as explained in Measurements for Eye Diagrams on
page 258. It is used to compute values like “rise” and “fall” times
and provides the eye height.

Specific optional signal processing algorithms (see Applying Advanced
Signal Processing Algorithms on page 72). Available algorithms depend
on the selected modulation format.

Pattern masks to test the quality of the signal and perform quick
pass/fail analysis (see Using Pattern Masks on page 64).
