Learn how to verify that a PTP system is performing as expected, using the checks that confirm real accuracy. The session covers the measurements that matter, as seen on the LT5600/LT7600 family of test instruments from Leader Electronics: offset from the reference, grandmaster identity and time source, and a view of the redundant network from both sides at once. It also covers measuring the relative skew of an ST 2022-7 pair, so a system that is beginning to drift shows itself early.
