The Tektronix VX4380 is a single-slot VXIbus relay matrix module that provides 256 crosspoints for signal routing and switching within automated test and data acquisition systems. Built around four independent 4×16 two-wire matrix sections, the module delivers flexible configuration options—combining sections to form a 16×16 or 4×64 two-wire matrix. Latching relay technology ensures low-power, low-noise operation across switching applications.
