ST-2135 E1/Datacom Transmission Analyzer
ST2135 E1/Datacom Transmission Analyzer is one 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 signalling 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.
