High-Performance Bit Error Rate Tester

Product center
SL3000B Series High-Performance Bit Error Rate Tester
BACK TO PREVIOUS

The SL3000B series High-Performance Bit Error Rate Tester features excellent performance metrics, a rich set of functions, flexible option configurations, and an extremely high level of integration. It provides powerful performance and a wealth of advanced features for the pre-research, design, and production testing of high-speed serial circuit products. The BERT can test and analyze the bit error rate in high-speed wired communication systems and is primarily used to evaluate the performance of electronic channels. It is an essential instrument for the R&D and testing of high-speed communication hardware circuits, widely used in universities, research institutes, communication equipment R&D, and aerospace research fields.

As the operating speeds of digital circuits increase, the signal transmission rates on PCBs, connectors, and back planes are also getting higher, with serial data communication playing a dominant role. Precision-designed -high-speed interconnects such as PCIe/ETH/VPX backplanes and high-speed cables,designed to the strictest perfor mance standards, have become crucial in the current context of widespread demand for high-speed signals in -national defense. The backplane is the communication backbone in embedded systems and must be designed according to strict signal integrity standards to ensure timely and accurate data transmission between modules within the system. As systems move towards supporting higher serial bit rates like 100G-baseKR4/CR4 and PCIe Gen4/5 protocols, high signal integrity is essential for achieving fail-safe operation. To meet the performance expec tations of high-speed transmission, especially for high-speed receivers, receiver tolerance testing is crucial.
