The GT-1CF 2M Transmission Performance Analyzer is primarily used to measure the bit error rate of communication line data transmission and analyze the causes of line faults. It conveniently performs transmission parameter measurements for 2M systems and N×64K channels, as well as routine maintenance testing.
