High Performance Frequency Dissemination by White Rabbit
The White Rabbit synchronization protocol, on which the new IEEE-1588-2019 High Accuracy PTP profile is based, is usually associated with distributed systems that have very demanding time requirements (sub-nanosecond accuracy and picosecond (ps) precision) for different markets such as: science, defence, finance, telecom (5G), smart grid, broadcast, etc. However, there are numerous applications whose synchronization needs are based on frequency dissemination instead of time distribution and that is why we wanted to analyze the performance of our equipment for these applications.
Timing the Industry by Swabian Instruments
Nowadays, the number of applications with very demanding time synchronization requirements are increasing in markets such as science, defence, finance, telecom (5G), smart grid, broadcast, etc. To meet such demanding specifications, protocols such as White Rabbit (capable of distributing time with sub-nanosecond accuracy and picosecond precision) were developed. However, as accuracy and precision improve, the measuring instruments used to monitor and ensure such performance must improve with them.

With the evolution of advanced networks like 5G, gaining time and frequency distribution becomes a critical yet demanding part of a network infrastructure.
New and developing architectures are challenged to improve network visibility and timestamping accuracy.
Timing the Industry
As the industry evolves, more and more applications with very demanding requirements for time and frequency synchronization are emerging. Examples of this need appear in many sectors such as transport, aeronautical, financial, health and telecommunications.
Many of these applications not only need a reliable, stable, and precise time reference to time stamp the different events that they need to monitor, but they must also distribute this main time source among all the devices that need to be synchronized and monitored with the highest possible precision and accuracy.
