Common synchronization reference for high-scale network testing

The Keysight metronome timing system (MTS) provides a common time, frequency, and phase reference across network test platforms. Designed to synchronize large-scale test environments, MTS supports up to 48 chassis using Metronome-STAR topology, including modular XGS systems and standalone appliances such as Keysight Novus ONE PLUS and AresONE. The system distributes synchronization from GNSS, 10 MHz, and other clock sources, delivering nanosecond accuracy across multichassis setups. Compatible with IxOS and other Keysight network test applications, MTS ensures consistent, repeatable timing for validating the real-world performance of Ethernet, time-sensitive networking, 5G, and AI data center networks.
