• GNSS Receiver — A receiver within the TEM Module that receives timing and
location information from one or more GNSS satellites via a connected GNSS
Antenna. The receiver processes the signals received from the satellites within a
GNSS constellation in order to provide high accuracy timing.
• GPS — Global Positioning System. Used throughout this manual to refer to a
literal GPS system (used globally).
• SBAS — Satellite Based Augmentation Systems. Systems that are used in
combination with GPS, GLONASS, or BeiDou navigation systems to enhance the
availability of GNSS satellites during surveys conducted in areas with poor satel-
lite visibility.
• TEM — Timing Expansion Module. The module can optionally be connected to
the back of the T-BERD ⁄ MTS 5800 to support testing using a Global Navigation
Satellite System (GNSS) based clock or other precise sources.
• Viavi Ethernet test set — A test set marketed by Viavi and designed to transmit
an Acterna Test Packet (ATP) payload. These packets carry a time stamp used to
calculate a variety of test results. The FST-2802 TestPad, the SmartClass
Ethernet tester, the HST with an Ethernet SIM, the T-BERD/MTS 8000 Transport
Module, the T-BERD/MTS 6000A MSAM, and the T-BERD ⁄ MTS 5800 can all be
configured to transmit and analyze ATP payloads, and can be used in end-to-end
and loopback configurations during testing.

This is the user manual for the T-BERD ⁄ MTS 5800 Timing Expansion Module (TEM).
It provides basic instructions for connecting the TEM to your 5800v2 test instrument,
connecting a GNSS antenna to the TEM Module (when deriving timing from GNSS
satellites), setting up the TEM Module to provide high accuracy timing, TEM specifica-
tions, and contact information for Viavi’s Technical Assistance Center (TAC). Read this
manual carefully before connecting the TEM Module to your instrument.
Use this manual in conjunction with the following manuals:
• T-BERD/MTS/SC Getting Started Guide. This guide provides an overview of the
connectors provided on the T-BERD / MTS 5800, instructions for connecting to
the circuit you are testing, and specifications for the T-BERD / MTS 5800
hard-
ware components.
• T-BERD/MTS/SC Ethernet and Fibre Channel Testing Guide. The manual
provides detailed instructions for testing on all supported networks. It also
explains how to run key scripts and describes each of the available test results.
• T-BERD/MTS/SC SONET, SDH, OTN and PDH Testing Manual for the
T-BERD 5800, SC 4800, MSAM, and CSAM. The manual provides detailed
instructions for testing on each of the listed networks.
