TEM V2 Timing Module

The rapid, dynamic adaptation and coordination of Radio Access Networks (RAN) will require more accurate synchronization from one generation to the next.  The VIAVI TEM V2 helps network operators maintain precise synchronization which results in an excellent customer experience, even as the ITU-T has tightened timing accuracy targets.

Together with T-BERD/MTS-5800 or OneAdvisor 800, the field-optimized TEM V2 delivers industry-leading accuracy to field portable timing and synchronization measurements.  It features a multi-band 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.

Highlights

With a T-BERD/MTS-5800/OneAdvisor 800 and TEM V2 combination, you can:

  • Improve time accuracy measurements with multi-band satellite receiver
  • Conduct field PTP Time Error measurements that allow you to confirm the stability and accuracy of Class C PTP Boundary Clocks
  • Enjoy best-in-class holdover time and pristine reference signals with highly stable Rubidium oscillators
  • Perform one-way delay measurements that help you root out asymmetric network delays
  • 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 to +/-5 ns (1-sigma)
  • Measure T1 and E1 jitter and wander

Benefits

  • Excellent Customer Experience; tightly synchronized wireless networks result in fewer dropped calls, and improved subscriber speeds.
  • Convenience; with its compact design, the TEM V2 is an extension to the T-BERD/MTS 5800 or OneAdvisor 800, which eliminates the need to carry a second test set for synchronization
  • Accuracy; long-term nanosecond accuracy even when operating in holdover with exceptional satellite reception

Key Features

  • 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
  • Multi-band 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
  • GNSS 1PPS pulse accuracy to +/-5 ns (1-sigma)
  • RF-48 conforming to G.703 specifications for 1PPS and Time of Day input
  • BITS/SETS Clock Input
