Finding the Overshoot and Undershoot of Each Aberration Region
The overshoot and undershoot of each region are calculated by taking the difference between the maximum
and minimum trace value of each aberration region and the local state level. Local state level being
(Low = pre-transition
High = post-transition) in a positive transition, and
(High = pre-transition
Low = post-transition) in a negative transition.
Tips for Improving Pulse Measurement Results
•
Set the reference level as close to the top of the trace as possible.
•
Use trace averaging.
•
For custom or irregular pulses, use a user defined top reference level (S2) instead of auto detection.
•
Use single sweep and sweep once buttons to take measurements one at a time.
