The Tektronix VX1405 is a 5-slot horizontal VXI mainframe engineered to integrate high-performance VXIbus instrumentation into benchtop test systems. This C-size mainframe delivers full VXIbus Specification Rev 1.3 compliance and supports both message-based and register-based modules through a high-power backplane architecture designed for optimal cooling and module accessibility.
Technical Specifications
• Form factor: Benchtop, horizontal 5-slot, C-size VXI mainframe
• VXIbus compliance: Full implementation of VXIbus Specification Rev 1.3
• Backplane: Two 96-pin VXIbus connectors (P1 and P2) per slot with signal timing, noise, crosstalk, termination, driving, and loading specifications per VXIbus Standard
• Module compatibility: C-size and smaller VXI modules
• Power input: Maximum 250V RMS between supply conductors or between supply conductor and ground
• Construction: Rugged aluminum chassis
– Key Features
• High-power backplane supporting comprehensive VXI resource access across all five slots
• Horizontal slot configuration optimized for thermal management and module insertion/removal
• Support for both external IEEE-488 controllers and embedded Slot 0 controller modules such as the Tektronix/CDS VX4544
• Full VXIbus connectors on each slot enabling point-to-point and daisy-chain module interconnection
– Typical Applications
The VX1405 serves as a platform for automated test, measurement, and data acquisition systems requiring modular instrument integration. It accommodates mixed instrument configurations including multimeters, digitizers, switches, and RF/microwave modules within a single integrated chassis.
– Compatibility & Integration
The mainframe integrates VXIbus modules via dual 96-pin connectors per slot and communicates with system controllers through HP-IB and RS-232 interfaces when equipped with a compatible controller module. Message-based instruments are typically controlled via SCPI commands through GPIB or RS-232 of a VXI controller. Protective grounding is essential; module covers must remain installed during operation and should only be removed by qualified service personnel.
