GAO-1AS/1BS/1CS 2M Transmission analyzer is mainly used for measuring bit error rate and analyzing the line fault and reason. It could easily accomplish transmission parameters measurement for N×64k channel of2M system and daily maintenance test. GAO-1CS 2M transmission analyzer could test for digital channel of 2M bit/s interface and digital channel of V.24 / V.28 / RS232 / V.35 / V.36?RS499 / X.21 / RS485 / EIA530 / EIA530A / codirectional 64kbit/s interface.
