The Tektronix VX1401 is a C-size VXIbus mainframe engineered for high-speed data acquisition and signal processing in automated test systems, research facilities, and development environments. This 13-slot modular platform integrates VXI instrument modules into compact, configurable test station architectures while maintaining compliance with VXIbus and VMEbus standards.
