At the 2016 Workshop on Synchronization and Timing Systems in San Jose, Ken Hann outlined how, with the right equipment, synchronization delivery and assurance can both be achieved.
Synchronization is a service which deliver Frequency/Phase/Time
Like other services , ways to monitor , test and analyze the quality of the service are needed
Clock Accuracy –Frequency ,phase and time accuracy measurement based on physical signals relative to reference
Clock Analysis - Frequency and phase analysis based on packet timing signals measured relative to reference
PTP Network Analysis - PTP path monitoring / testing
