Calnex Sentinel


Calnex Sentinel is a All-in-one dedicated synchronization tester -  verify static and dynamic time, phase and frequency synchronization performance on your packet network. Sentinel is the field solution for 3G/4G/5G Mobile Backhaul, E911/Critical Infrastructure, Financial Networks and Power Comms. The new Sentinel’s non-invasive Over-The-Air test capability allows you to measure, with precision, the Time Error between eNodeBs or gNodeBs and UTS to ensure they meet the 3GPP standards. Sentinel allows you to easily and thoroughly verify and monitor the synchronization within your datacenter, and prove time/phase accuracy with microsecond precision.


  • Verify Phase, Time and Frequency synchronization 

  • Test 3G/4G/5G and Small Cell deployments at various points in the network, including near to the GrandMaster (GM), and validate network performance to ITU-T limits.

  • Time Error (TE)

  • Time Interval Error (TIE) 

  • MTIE

  • TDEV

  • ESMC Quality Levels 

  • Max 2way TE 

  • Dynamic Time error 

  • Max Packet Selected 2Way TE 

  • SyncE wander Packet Delay Variation (PDV) 

  • Floor Packet Percentage (FPP) Frequency Error
