Connection diagram for random jitter calibration (M8040A)

Parameters in Expert Mode

• Transitions: The number of transitions (0 to 1 or 1 to 0) used for the

jitter measurement.

• Stop Jitter: The final jitter value for the calibration procedure.
• Jitter Step Size: The difference value of set jitter between two jitter

measurements.
