Other Products
The HCT-BERT/T is a handheld E1 transmission analyzer featuring a true-color screen, graphical interface, and fully Chinese operation interface. It is used for field maintenance and analysis of E1/G.703 lines, error code testing of G.703-64K, channel testing of PCM31/30, and audio signal insertion. The HCT-BERT/T is fully functional and easy to operate. It can analyze and display test results according to international standards such as G.821, G.826, and M.2100, and also store, statistically analyze, and evaluate test data based on user requirements, making it a powerful tool for line quality measurement and analysis.
