BER-1580 Data Transmission Analyzer with Jitter

During the activation of a carrier's 2M line, it is necessary to determine whether the line's bit error rate and alarm indicators meet the activation conditions. In fault localization and handling, it is essential to assess whether there are issues with the line equipment.

The BER-1580 product is suitable for high-end applications such as carrier 2M equipment maintenance, inspection, and testing of frame relay services for major telecom clients. It can perform bit error rate testing at rates from 50b/s to 2048kb/s and supports 2M online testing, making it an indispensable tool for the daily maintenance, inspection, and activation of communication equipment. Supported interfaces include G.703, V.24/RS232, V.35, V.36/RS449, X.21, EIA-530/530A, and RS485/RS422. The BER-1580 also supports 2M jitter transmission/reception testing, 2M synchronous clock testing, and frame relay testing. The instrument features an RJ45 network interface, supports complete TCP/IP protocols, and allows for online upgrades. Its unique remote testing function enables users to perform real-time testing conveniently via software in a Windows Chinese environment.
