Product Description

Overview – Portable E1/Datacom Transmission Analyzer

This E1/Datacom transmission analyzer is designed for performing comprehensive analysis, measurement and evaluation of telecom networks. It performs E1 frame data monitoring and analysis, dual E1 channel testing, loop delay, APS delay, pulse measurement, jitter measurement, signal level measurement. It also has many enhanced test functions such as "PCM Simulator", "Mux/Demux", "Drop & Insert" and "Network Tools". It is widely used in R&D, production, installation, verification and maintenance of SDH, PDH, PCM, DTU and Data protocol converter equipment.
