TERADYNE Semiconductor Tester Board LA824 LA823

The LA824 and LA823 are both circuit board components used in Teradyne semiconductor test systems, though they serve different purposes. The LA824 is a PCI adapter board primarily designed for signal routing; it is equipped with four-channel bus transceivers and 16-bit bidirectional transceivers. The LA823, by contrast, is classified as an industrial test board or interface card; according to available documentation, it is used for signal conditioning, high-precision measurement, and I/O expansion, featuring multi-channel analog and digital interface capabilities.
