VeEX TX150E+ Handheld SDH/PDH Test Set

SDH network testing simplified

The TX150/E+ is a compact and ruggedized tester for installing, commissioning and troubleshooting SDH, SONET, PDH, T-Carrier and G.703 64k Codirectional networks. Configuration of the test setup is simplified by the color touch-screen, test system block diagram and intuitive menu structure and shortcuts. Electrical and optical signal levels, alarms, errors, overhead byte analysis and generation, histogram, and other test criteria and results can be quickly accessed with a stylus. The TX150/E+ supports SDH/SONET, PDH, DS3 and DS1 signal mapping and multiplexing structures making it suitable for a global customer base. In addition, ITU performance measurements, E3/E1/DS3/DS1 pulse mask analysis, complete error/alarm injection, APS, Service Disruption, Tandem Connection Monitoring, Pointers, Trace Identifiers, >2000 test results storage and field changeable LiIon battery are all packed into this field friendly unit weighing in at less than 1kg. The TX150/E+ is also the industry’s first handheld SDH/SONET/PDH/T-Carrier Analyzer to offer Triple Play service verification functions on the standard Ethernet LAN interface. The unit can be remote controlled for monitoring applications and other offsite or remote tasks.

The TX150+ is available in two hardware versions – TX150+/TX150E+ (red) and TX150+/TX150E+. Before downloading software from the links on this page, identify the correct hardware of your unit by the color of the plus "+" sign on the front LED panel.
