Key Features Multi-protocol synchronization validation on a single platform eliminates need for multiple test instruments. Built-in GNSS receiver with holdover ensures continuous timing verification during satellite signal interruptions. Ethernet connectivity supports both twisted-pair and fiber optic transport. Real-time display enables immediate result interpretation during field commissioning and troubleshooting.

Typical Applications Network operators deploy the SyncWatch-110 for 5G timing validation, mobile backhaul synchronization verification, and data center clock distribution audits. Field technicians use it for on-site PTP profile confirmation and SyncE source qualification prior to network integration.

Compatibility & Integration The unit operates with standard Ethernet infrastructure via RJ-45 and SFP connections. Time-of-Day outputs interface with NTP and PTP timing systems. GNSS antenna ports accept standard connectors for rooftop or external antenna placement.
