VeEX® introduces '1PPS Clock Phase Analysis' for Mobile Backhaul tester.

VeEX, a global leader in Telecom and CATV test solutions, today announced the introduction of the new Clock Phase Analysis for its TX130M+ test set.

With the growing deployment of 4G/LTE networks worldwide, 1PPS Phase Analysis has fast become one of the most important clock recovery tests for eNodeB installation and maintenance applications. In particular, any phase alignment or difference between a reference clock (e.g. local GPS reference) and the 1PPS signal recovered by the PTP edge clock at the base station or small cell site is absolutely critical.

Forming an integral part of the TX130M+ Clock Wander Analysis option, the 1PPS phase analysis feature quickly verifies that the timing accuracy complies with the ±1.5µs phase error (time error) acceptance limit defined for LTE-TDD and LTE-Advanced deployments. This feature is also useful to adjust edge clock offsets in order to compensate for cable length and related equipment-induced delays.

Furthermore, Mobile operators faced with these demanding and stringent network timing requirements now have a handheld, field portable tester capable of conducting long-term synchronization performance tests, including Absolute Phase Error (accuracy) and Wander (stability) in a single test, reducing overall test time onsite.

This functionality is available to existing Clock Wander Analysis customers who update to software version v1.11.0-0 and will be available for demonstration during the upcoming "2013 Telcordia-NIST-ATIS Workshop on Synchronization in Telecommunication Systems" - San Jose, CA, April 16-18.
