DTA-SDH/155 SDH/PDH Transmission Analyzer

The DTA-SDH/155 transmission analyzer is a palm, graphic, color-LCD SDH/PDH measuring instrument designed for field use in analysis and maintenance of STM-1(155Mbps) and E1(2.048 Mbps) lines. The DTA-SDH/155 has optic and electric port, evaluate and analysis result according to ITU-T G.821, G.826, G.828, G.829, M.2100, M.2101. Its easy operation, light weight, long working hours, low price, may be the ideal solution for field work.
