IFR Aeroflex STD-7000 ARINC Bus Controller

The IFR Aeroflex STD-7000 ARINC Bus Controller is a programmable device that generates, receives, and monitors ARINC 429 and ARINC 453 bus traffic for avionics test applications. Part of the Standard Digital Interface System (SDIS), the STD-7000 works with an Operator Terminal to simulate bus conditions, validate system responses, and verify data integrity through real-time CRT display and analysis. It serves as the central control element for ARINC 700 series test configurations, interfacing with Units Under Test through discrete signal monitoring and bus command activation.

– Technical Specifications

• Six programmable high/low speed ARINC 429 I/O buses
• Three programmable very high speed ARINC 453 I/O buses
• One IFR I/O bus for auxiliary test equipment interface
• One IEEE Standard 488-1978 (GPIB) bus for external ATE Controller integration
• One EIA RS232C bus for Operator Terminal interface
• CRT display with dedicated CRT interface
• 16-key numeric keypad for operator input

– Key Features

• Programmable control of serial bus communications across ARINC 700 series avionics systems
• Simultaneous generation and reception of ARINC 429/453 data
• Real-time data display enabling rapid system integrity verification
• Discrete signal monitoring for Unit Under Test performance assessment
• Modular architecture with dedicated Bus Logic Input, Bus Analog Input, ARINC 429 Bus Output, VHS Output, CPU, I/O, EPROM, and RAM memory boards

– Typical Applications

• Commercial aircraft avionics equipment testing and validation
• ARINC bus protocol compliance verification
• Discrete control and monitoring of avionics subsystems
• Integration with automated test environments via GPIB interface

– Compatibility & Integration

The STD-7000 supports ARINC 429 (twisted pair balanced differential signaling) and ARINC 453 Very High Speed Bus standards. ARINC 453 originally served as a general-purpose data bus in weather radar products including ARINC 708 and 708A implementations. IEEE 488-1978 connectivity enables seamless operation within larger automatic test equipment systems.
