2M Transmission Analyzer is a multi-functional and full- featured digital transmission system test device, designed for the installation test, engineering check and acceptance, daily maintenance of digital networks, mainly performing channel test, alarm analysis, fault finding and signaling analysis. In addition, this instrument further provides various protocol converters with one-way and bi-directional bit error test function. These capabilities
make it ideal for field use.
