Overview
The Calnex Paragon neo is a PTP and SyncE test platform for interface speeds up to 100GbE. It is intended for network equipment manufacturers developing, verifying and manufacturing devices against enhanced timing standards such as ITU-T G.8273.2 Boundary Clocks and O-RAN compliant O-DU and O-RU equipment, and for those designing and deploying 5G networks.
The instrument emulates PTP timeTransmitter and timeReceiver clocks, applies standards-defined Time Error impairments, and measures output packet timing, recovered clocks and SyncE wander simultaneously. A conformance test application configures standards-defined test sequences and automatically generates PTP and ESMC messages, Time Error and SyncE impairments.
SyncE testing to ITU-T G.8262.1/G.8262 covers wander tolerance, transfer and generation, pull-in, hold-in and pull-out ranges, frequency accuracy, phase transient, jitter tolerance and jitter generation. Results are evaluated in the Calnex Analysis Tool against ITU-T and O-RAN masks.
Key Features
- Calnex Analysis Tool (CAT) for evaluating Time Error, MTIE and TDEV against ITU-T masks
- PTP Field Verifier (PFV) analysis of PTP protocol conformance to standards-based or user-defined profiles
- PTP and SyncE testing at speeds up to 100GbE
- Conformance test application with two-click configuration of standards-defined test sequences
- Emulation of PTP timeTransmitter and timeReceiver clocks with Time Error impairments
- Simultaneous measurement of SyncE wander and PTP Time Error
- SyncE jitter and wander generation and tolerance testing to ITU-T G.8262.1/G.8262
- ESMC (SSM) message generation and decode to ITU-T G.8264
