Datasheet

The Tektronix BSX-BertScope series includes interactive link training at data rates up to 32 Gb/s. With the addition of powerful data processing and internal Tx equalization, the Tektronix BSX-BERTScope series supports protocol-based handshaking and synchronization with a device under test (DUT). The Tektronix BSX-BERTScope series Bit Error Rate Tester introduces a receiver test platform capable of supporting emerging 4^th-generation standards and beyond. The BSX-BERTScope series shortens the time to debug the physical layer and link training issues. Additionally, this series of BER testers provides the quickest path to compliance for a broad range of industry standards.

The BSX-BERTScope series memory sequencer implements flexible, indirect access to pattern memory. The pattern memory can support two levels of loop nesting with up to 1 million iterations per loop. To further simplify programming and increase memory efficiency, individual pattern segments can be any size greater than 128 bits. Advancement of the memory sequence can be controlled by software control, external signal, or detector pattern match -- this provides the user with multiple means of controlling handshaking with their test devices.

The Tektronix BSX-BERTScope series contains the following models: the BSX125, the BSX240, and the BSX320.
