Supporting Your Changing Environment

As the world prepares for 5G, the levels of synchronization accuracy and speed of data transfer required are increasing exponentially. In response, the ITU-T is enhancing the G.827x series of standards to cover next-generation accuracy requirements for PTP and SyncE synchronization technologies.

Paragon-neo offers hardware performance and software test methodologies allowing picoseconds-level accuracy for the entire test system – essential for validating new devices such as Class C/D Boundary and Slave Clocks.

5G Ready

Highest accuracy for PTP and SyncE testing to new ITU-T 5G synchronization specifications, with speeds up to 100GbE – addressing all 5G enhanced time requirements.

Robust Testing

‘Two-click’ test case driven workflow allows the entire testbed in a box, all controlled simultaneously to ensure accurate, repeatable timing of stimulus, impairment and measurement.


Hardware options for SyncE Jitter to ITU-T G.8262.1 and G.8262, internal and external high accuracy reference options for PRTC testing and a rear expansion slot for further upgrades.

Features and Benefits

Best-in-Class Accuracy
Leveraging years of experience in PTP and SyncE testing, Paragon-neo delivers sub-nanosecond accuracy for key timing measurements.
Easy Configuration
PTP device emulation, Time Error impairment patterns, SyncE Jitter and Wander noise, all automatically controlled.
Real-Time Analysis
Calnex Analysis Tool (CAT) and PTP Field Verifier (PFV) allow real time pass/fail analysis of complex timing metrics and PTP profile conformance, all with one-click report generation.
