VeEX announced the availability of a GPS-synchronized one-way latency measurement for its TX300 test set. The new option is designed to measure the end-to-end traffic delay between two geographically separated TX300 test sets, synchronized via GPS, to independently report the exact frame delay in the forward and return paths. Combined with its multi-stream throughput test functions, the TX300 solution s intended to ensure that all classes of service meet their SLA requirements.
