Overview
The Tektronix 73A-455 is a dual-channel MIL-STD-1553A/B bus simulator module designed for integration into VXIbus-compliant card cages. This module enables comprehensive testing and simulation of MIL-STD-1553 avionics data-bus protocols commonly used in aerospace and defense systems. The 73A-455 provides reliable channel simulation and monitoring for automated test equipment (ATE) environments.
Key Features
- Dual independent MIL-STD-1553A/B bus simulation channels
- VXIbus Specification compliant C-size module
- Transformer-coupled front panel connections (standard and Opt 2N)
- Programmable bus protocol control and data monitoring
- Integrated test and simulation capabilities for avionics applications
- Compatible with Tektronix CDS 73A IAC test systems
Technical Specifications
The module meets industry standards for MIL-STD-1553 bus simulation and operates within VXIbus framework specifications. Optional configuration Opt 2N provides high input impedance (1 MHz) on transformer-coupled outputs for specialized test configurations. The printed circuit board assembly conforms to VXIbus message-based protocol architecture.
