2M Transmission Analyzers 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, NX64K communication channels.
Major Features
●English menu, Large screen, Easy operation.
●Multitask operation (It is allowed to conduct a test while browsing
previous records).
●Test results can be stored, and kept in memory in the event of
power failure.                                                                                                               
●The instrument can be powered on or off at certain times for testing purpose.         
●Column diagram analysis of alarms and error codes.                                               
●Software updating online
Major Functions
●Service-interrupted error code testing;
●Framing and non-framing signals generation and reception;
●2 Mbit/s non-framingÿ error code performance testing;
●2 Mbit/s framing NX64kbit/s channel error code performance testing;
●Performance testing of bit error, coding error, frame error, CRC error and E bit error;
●Alarm testing of signal loss, AIS alarm, frame remote alarm, multiframe remote alarm,
out-of-frame, and out-of-pattern synchronism;     
●Frequency swing testing;                                                                                                
●Through mode;  
●G. 821/G. 826/M. 2100   error code performance analysis; 
●Two clock options (internal and picking-up);
