SDH/PDH Transmission Analyzer with APS Functions

Toronto, Canada - GAO Comm ( recommends its SDH/PDH transmission analyzer for pulse mask analysis, overhead analysis, point analysis and anomaly/defect analysis as well as bit error rate (BER) testing. The analyzer is commonly used in R&D, manufacture, acceptance testing, performance monitoring and maintenance and measurement of SDH/PDH networks and devices.

This SDH/PDH transmission analyzer, model A0020005, features flexible software-definition and simulated LEDs for current and historical error indication. It has various functions including automatic tributary scanning, automatic protection switching (APS), round trip delay measurement, TCM serial monitoring, timing and synchronization testing and real-time optical power testing. Its performance analysis conforms to G.821, G.826, G.828, G.829, ZM.2100 and M.2101 international standards.

This advanced, handheld SDH/PDH transmission analyzer incorporates electrical interfaces for SDH/PDH and optical interfaces for SDH/SONET with completely independent Tx and Rx. It has a large memory capacity to record bit error and alarm events that can be displayed in charts and graphics. Test results can be saved as HTML or TXT format and uploaded to USB disk or a computer for further analysis, reporting and printing.

This SDH/PDH transmission analyzer belongs to GAO's family of E1 BER Testers. This line also includes Portable E1/Datacom Transmission Analyzer which is widely used in R&D, production, installation, verification and maintenance of SDH, PDH, PCM, DTU and Data protocol converter equipment, Handheld E1 Bit Error Rate (BER) Tester which is an ideal device for fast problem resolution, E1 PCM line access, maintenance and acceptance testing and Integrated Data Transmission Analyzer which is used for measuring the error rate of data communication and for the analysis of line faults and their causes for the routine maintenance testing of 2M systems, N×64 k communication channels.
