Set Mask Scaling
With mask scaling the mask can be manually enlarged, shrunk, and
moved around. With the logic levels track selected, the mask regions are
bound together, and move together with a fixed amplitude. Position
(pos) gives the timing displacement, and dT gives the delta time offset.
Set Mask Run Control:
The Mask Run Control aligns the mask, switches it on, starts displaying
the number of waveforms, and the number of mask violations per mask
region, and the worst BER per Mask region.
Exit stops the computation, hides the mask, and the violations.

Description

Rise time
Measures the mean
transition-time taken by
the data on the rising edge
of the eye diagram. The
data crosses three
thresholds: lower,
crossover point, upper and
the eye transition.
Note: Rise time is
dependent on the
Transition Time of the
View Tab. The two options
are 10/90 and 20/80.
