Viavi C5TEM-R

Together with the T-BERD®/MTS-5800 family, the field-optimized TEM delivers industry-leading accuracy to field portable timing and synchronization measurements. It features a GNSS antenna and a miniature atomic clock (MAC) to ensure nanosecond accurate measurements even when a satellite signal is not present and the module is running in holdover. 

With a T-BERD/MTS 5800 and a TEM, you can: 

• Perform one-way delay measurements that help you root out asymmetric network delays 
• Precisely measure PTP one-way delay, constant time error (cTE), dynamic time error (dTE) using wander analysis with ITU masks and maximum time error max |TE| 
• Measure Floor Packet Percentile (FPP) of the Sync PDV packets to ensure PTP PDV is within limits for recovering frequency 
• Qualify GNSS antenna installations by evaluating satellite signal strength and viewing 360° sky plot either instantly or over a 24 hour period 
• Troubleshoot the accuracy of equipment 1 PPS output signals with 1 PPS wander analysis 
• Measure T1 and E1 jitter and wander 
• Measure PTP Frequency accuracy using a Floor Package Percentile (FPP) analysis
