2M BERT Tester

Máy đo kiểm E1 - 2M Transmission Analyzer TLP-3C
Introduction:
The 2M Transmission Analyzer TLP-3C 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 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.
