TO Test E1 Line And Datacom Interface E1 BER Tester

SAT-1CS  2M Transmission Analyzers, also called E1 BER Tester , is mainly used for measuring of the error rate of data communication and for the analysis of line fault and causes, and very suitable for the parameter measurement and routine maintenance testing of 2M system, N×64K communication channels.SAT-1CS 2M Transmission Analyzers can be used to test the digital channels with 2Mbit/s interfaces and with V.24/V.28/RS232, V.35, V.36, RS449, X.21, RS485, EIA530, EIA530A, and equidirectional 64kbit/s interfaces.
