Data Communication Test - Timing Synchronization Tester - Shenzhen TopSynce Electronic Technology Co., Ltd

Product Overview

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 – to ensure that Ethernet systems are robust against varying transmission delays and other effects that can significantly disrupt the precise transfer of timing.

These ITU-T standards also form the foundation of timing requirements for new Open Radio Access Networks, and are inherently required for O-RAN compliance.

The Paragon-neo is the latest platform from Calnex, providing PTP and SyncE testing of speeds up to 400GbE (Paragon-neo A (PAM4)) or 100GbE Paragon-neo. It’s designed to meet the stringent test requirements of NEMs who are developing, verifying and manufacturing devices against enhanced timing standards such as for ITU-T G.8273.2 Class-C/D Boundary Clocks, O-RAN compliant O-DU and O-RU equipment, and for those designing and deploying 5G networks and systems. What’s more, because high network efficiency and reduced data transmission costs are only possible with highly accurate timing, Paragon-neo offers hardware performance and software test methodologies allowing sub-nanosecond accuracy for the entire test system.

To meet the timing challenges of 5G deployments, Calnex is committed to providing the most advanced, precise and reliable test solutions to make sure your devices and systems deliver the high quality network services of the future. In a changing world, it’s good to know that somethings never change.

Key Features

PTP Field Verifier (PFV)

Analyze PTP protocol for conformance to standards or user defined profiles.
Automatic pass/fail indication – check captured PTP messages against a pre-defined set of rules, with clear pass/fail alerts.

Conformance Test Application

Start testing in seconds – just two clicks to configure crucial standards-defined test sequences.
Automatically generates PTP and ESMC messages, Time Error and SyncE impairments, and applies filters, metrics and masks.

Analyze the Time Error (TE) of, for example, Class-C/D T-Boundary Clocks or Class-B PRTC/Master Clocks.
Apply standards-defined Time Error impairments.
Combine with SyncE and ESMC for complex tests such as Phase Noise Response to SyncE Transient.

PTP Applications

Test hybrid devices simultaneously with PTP Time Error/SyncE wander and measure output packet timing, recovered clocks and SyncE wander with unbeatable test accuracy and repeatability.

Application		Standard
Boundary Clock Testing		ITU-T G.8273.2
Transparent Clock Testing		ITU-T G.8273.3
PTS and APTS Clock Testing		ITU-T G.8273.4

The Calnex Analysis Tool (CAT) provides powerful insight into network and device performance. All your measurement results are now in one place, and you can view multiple graphs simultaneously for easier correlation of your results. Plus, with enhanced graphics, it’s easy to evaluate metrics such as MTIE and TDEV against ITU-T and O-RAN masks.
