Chapter 1 Overview
About the TEM Module
T-BERD/MTS 5800 Timing Expansion Module User Manual
Page 2 22112315, Rev. 004 July 2017
About the TEM Module
The TEM Module provides a stable, highly accurate timing reference for the T-BERD /
MTS 5800v2, and the ability to conduct synchronized timing tests across multiple
instruments with the support of a Global Navigation Satellite System (GNSS) and an
internal rubidium oscillator. This equips technicians and engineers to perform highly
accurate one-way delay testing; timing and synchronization experts to measure time
and phase on systems, particularly wireless systems that require precise synchroniza-
tion; and certification labs to verify timing and synchronization of new equipment and
network configurations. The TEM Module can also be used to provide a stable external
timing reference via the 1PPS and 10MHz output connectors on the module.
Finally, the TEM Module also provides field construction teams with the ability to qualify
GNSS antenna installations by verifying the strength of signals received from specific
satellites and detecting obstructions to the antennas.
Features and capabilities
Features and capabilities of the TEM Module include the following (assuming your
5800v2 instrument is optioned and configured to do so):
•Rubidium Oscillator. The TEM Module is equipped with its own, dedicated
rubidium oscillator which tunes to the frequency of a specified synchronization
source (for example, a GNSS satellite, or an external 1PPS or 10MHz reference
clock). After tuning, the oscillator on the TEM Module can be used as the timing
source when performing measurements that require highly accurate timing, or to
provide an external timing reference to another device.
•Holdover mode. After the TEM Module’s oscillator warms up and is tuned to the
frequency of the synchronization source, it can be placed into holdover mode,
allowing the TEM Module to use its own rubidium oscillator as a stable timing
reference for a period of time while using the connected instrument to perform
tests. After the oscillator is placed into holdover mode, the signal from which
synchronization was obtained can be disconnected.
•GNSS antenna. A GNSS antenna ships with the TEM Module. When connected
to the TEM module, provides the highest accuracy and stability using the
module’s high precision GNSS timing receiver.
•GNSS high precision timing receiver. The TEM Module provides a GNSS high
precision timing receiver, which supports all GNSS frequencies when a GNSS
antenna is connected.
•Supported GNSS Systems. The TEM Module supports GNSS systems for satel-
lite constellations that are available worldwide (GPS and GLOSNASS), and in
specific areas of the world (for example, BeiDou). If they are available, satellites
supporting different GNSS systems can be selected as sources of timing informa-
tion.
•GNSS surveys. You can configure the TEM Module to survey GNSS constella-
tions, obtain position measurements from satellites within the constellation, and
then and then generate accurate coordinates based on the average position
measurement.

What ships with the TEM Module?
T-BERD/MTS 5800 Timing Expansion Module User Manual
July 2017 22112315, Rev. 004 Page 3
•Satellite Based Augmentation Systems (SBAS). SBAS can be used in combina-
tion with GPS, GLONASS, or BeiDou GNSS systems to improve the availability of
satellites during surveys of areas with poor satellite visibility. In the future, QZSS
augmentation will also be supported for satellite constellations in Japan and
Australia.
•Saved GNSS coordinates. If you intend to conduct testing at a particular location
on a routine basis, you cansave the coordinates for the location, and then retrieve
them before testing.
•External Synchronization Sources. In addition to the internal GNSS receiver, you
can configure the TEM Module to use an external BITS/SETS clock, an external 1
Pulse Per Second (PPS signal), or an external 10 MHz signal to tune the
module’s rubidium oscillator.
•Precise one way delay measurements. By synchronizing two 5800v2 test instru-
ments (each with a connected TEM Module), you can use the instruments to
accurately measure one way delay.
•Precision Time Protocol (PTP) Time Error, Asymmetry, and Packet Delay Varia-
tion (PDV) measurements. You can also use a 5800v2 instrument with a TEM
Module to operate as a PTP slave, and measure time errors and PDV against a
PTP Grandmaster or boundary clock.
•Wander analysis. You can use the TEM Module as a highly precise reference
when conducting 1PPS Wander measurements with a 1PPS input signal under
test. You can also use the TEM Module to provide a highly precise timing refer-
ence when conducting DS1/E1, 10MHz/2MHz Clock, and 1GigE Optical Ethernet
wander analysis.
•High precision 1PPS wander analysis. If your TEM Module is optioned to do so,
you can use it to perform highly accurate wander analysis of a 1PPS signal in a
graphical manner by measuring the Time Interval Error (TIE) and calculating the
Maximum Time Interval Error/Time Deviation (MTIE/TDEV) on the module itself.
You can also export TIE data for analysis on a PC using optional O.172 MTIE/
TDEV Offline Analysis software.
•GNSS antenna installation qualification. You can use the TEM Module (with a
connected GNSS antenna) to determine the quality of the signals received from
selected GNSS satellites, and to verify that a stationary antenna has been
installed at the optimal location.
For a comprehensive list of features and capabilities for specific technologies or proto-
cols (for example, Ethernet or SONET), refer to the Testing Manual that shipped with
your instrument or upgrade.
