Import Ber Tester — Buy in Bulk from Supplier in China

The TL3000EVR series bit error rate tester from Beijing Toplink Technology Development Co., Ltd. is a handheld diagnostic instrument designed for field verification of digital communication channels. It supports asynchronous RS-232, synchronous RS-232, synchronous V.35, synchronous TTL-level, and transparent or framed E1 and E2 interfaces, with user-configurable interface rates across all supported standards. The instrument integrates a digital frequency counter with measurement accuracy of 10 ppm, a real-time clock, and automatic test-result logging for later retrieval. Power is provided by a rechargeable lithium battery delivering over four hours of continuous operation, supported by low-power large-scale IC design and efficient power management.

Construction centres on a compact handheld enclosure with Chinese-language LCD and menu-driven interface, aimed at communication engineers requiring portability for site work or business travel. The meter analyses comprehensive error-code performance indices to characterise channel quality, with firmware update capability via online connection to maintain protocol compatibility as standards evolve. No specific dimensions, weight, operating-temperature range, or ingress-protection rating are stated in the source data. The instrument is positioned as suitable for field technicians engaged in installation, commissioning and fault-location tasks on digital transmission networks.

Buyers of the TL3000EVR series typically include telecom equipment installers, network maintenance contractors, railway signalling departments, and broadcast-transmission operators in markets where E1/E2 and serial data interfaces remain prevalent. The device bridges laboratory-grade test capability with battery-powered portability, a combination that reduces truck-roll costs for service providers.
