GAO Tek Data Transmission Analyzer and E1/T1 BER Tester


Product Description


This data transmission analyzer is designed for frame synchronization code monitoring, CRC monitoring, offline error testing, signal waveform analysis, IP PING testing, offline and online monitoring and ITU-T G.703 error analysis.

The data transmission analyzer and E1/T1 BER tester performs error code testing at the rate of 50 b/s to 2048 kb/s and offers online monitoring for routine maintenance, repair and operations monitoring of communication equipment. It offers a special remote function to perform real time monitoring. This tester has testing functions for G.703, V.24/RS232, V.35, V.36/RS449, X.21, EIA-530/530A, end-to-end testing, voice and frequency measurement, remote loopback testing, E1 pulse mask, and PING testing.

The portable data transmission analyzer is shipped with a large and backlight color TFT LCD. Built-in rechargeable Li-ion battery allows up to 8 hours field operation without external power supply. It supports RJ45 interface and complete TCP/IP protocols with online upgrade available.
