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 can save 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
