PRODUCT OVERVIEW

VIAVI Solutions’ Timing Extension Module (TEM) helps network operators maintain precise synchronization which results in an excellent Customer Experience. Together with the T-BERD/MTS-5800, the field-optimized TEM delivers industry-leading accuracy to field portable timing and synchronization measurements.  It features a modern 72 channel GNSS antenna input and an extremely accurate Rubidium based miniature atomic clock (MAC) to ensure nanosecond-precise measurements even when a satellite signal is not present and the module is running in holdover.


Features

  • Perform one-way delay measurements that help you root out asymmetric network delays

  • Conduct field PTP Time Error measurements that allow you to confirm the stability and accuracy of your PTP Boundary Clocks

  • Precisely measure PTP PDV to pre-qualify or troubleshoot non-PTP-aware networks

  • Qualify GNSS antenna installations by evaluating satellite signal strength and eliminating antenna faults

  • Troubleshoot the accuracy of equipment 1 PPS output signals with 1 PPS wander analysis

  • Measure T1 and E1 jitter and wander

  • Verifies Ethernet and IP one-way delay network latency

  • Confirms frequency, phase, and time synchronization with near-lab grade accuracy in the field

  • Proves out GNSS antenna installations and faults

  • Supports multiple GNSS constellations including GPS, GLONASS, BeiDou, SBAS, and QZSS

  • Enable fast and accurate satellite acquisition with a modern 72 channel GNSS receiver

  • Supports multiple 1 PPS and 10 Mhz inputs and disciplined outputs

  • Performs 1588v2 (PTP) measurements including nanosecond-accurate PDV and time measurements

  • PTP grand master (PRTC) emulation

  • Nanosecond accurate one-way delay 1/10 GE measurements
