The Keysight E1465A is a C-size, 1-slot VXI module that implements a 16×16 two-wire relay matrix switch for signal routing in automated test systems. Each crosspoint switches both high and low using electromechanical relays, delivering low signal distortion across a wide range of applications. The module accepts channel lists downloaded to onboard memory, streamlining complex routing configurations. Expansion capability allows interconnection with E1466A and E1467A modules via chaining cables to create larger matrices up to 32×32, making it suitable for scaled test architectures.
