¡ô General

RY-4100A Series  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, N¡Á64K communication channels.

¡ô Major Features

 ¡¤English menu. Large screen. Easy operation.

 ¡¤Multitask operation (It is allowed to conduct a test while browsing previous records).

 ¡¤As many as 9 test settings and 20 groups of test results can be stored, and kept in memory in the event of power failure. .

 ¡¤Communication with a PC is available to allow test data storage, analysis and printing to be carried out on the PC, or directly connected to a micro printer.

 ¡¤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.
