BER Testers

GAO Tek provides a large selection of high-quality and cost-effective BER testers. Bit error rate testers (BERT) are designed to measure the number of errors in a data transmission system. A data transmission system is any piece of equipment that takes in data and outputs the data, possibly transforming it in the process, or it may be a communications link that passes the data from one location to another. The number of errors can be reported as a simple count of bits in error or as a ratio of bits in error to total bits checked. This ratio is commonly referred to as the Bit Error Rate. GAO Tek’s BER testers are easy-to-use devices that are vital for validating or certifying digital designs. They allow users to quickly and accurately test cables and diagnose signal problems in the field. The devices are used to generate and check a variety of bit patterns as they provide easy adjustment and validation of transceivers. Given the advanced features and functions, GAO Tek’s effective and reliable BER testers are the perfect solution for any telecommunication technician or engineer.

Functions of BER Testers

Bit Error Rate Testers are designed for testing synchronous serial communications equipment, communications links and radio telemetry systems. GAO Tek’s BER testers generate a test data stream that is passed through the data transmission system. The BERTs then checks that data stream against a reference data stream and detects any errors introduced by the system under test. They detect bits in error and missed bits (also called bit slips). Basically, the testers measure BER by transmitting a pseudo random bit sequence, and comparing the received sequence with an error-free replica generated at the receiver. The BER testers are basic tools for digital communications measurements.

Features

The devices feature self-check and keyboard testing, extensive error and alarm generation, detection and indication. They provide smart menu navigation and have a large color LCD screen allowing test results to be displayed clearly. Test results can be downloaded or printed via included software. BER testers are cost-effective devices that are well-constructed and very light in weight. GAO Tek’s BER testers are ideal devices for fast problem resolution, E1 PCM line access, maintenance and acceptance testing.

Applications and Industries

The BER testers allow the most accurate and efficient design verification, characterization, compliance and manufacturing test of high-speed communication ports for today's ASICs, components, modules and line-cards in the semiconductor, computer, storage, and communication industry.
