The Merlin MVXI1465 (E1465A) is a C-size, 1-slot VXI module that implements a 16×16 two-wire relay matrix switch for signal routing in modular test systems. Register-based control enables downloadable channel lists into onboard memory, while daisy-chain expansion via chaining cables supports creation of larger matrixes up to 3072 crosspoints in a full 13-slot E1401B mainframe. Each crosspoint switches both high and low, making it suitable for multi-channel signal conditioning and routing in automated test environments.
