– Key Features
• Dual independent ports eliminate protocol switching overhead
• Selectable bus frequencies and word update rates optimize testing flexibility
• Programmable breakpoints capture anomalies and failure conditions
• 40,960-word history buffer preserves transient events for root-cause analysis
• Dynamic transmit capability generates complex signal patterns for system validation
– Typical Applications
• Line maintenance and troubleshooting of avionics databus systems
• Benchtop verification of aircraft data communication interfaces
• MRO integration testing and hand-off validation
• Field ramp diagnostics and fault isolation
– Compatibility & Integration
Standard interfaces include RS-232C and 12-bit DAC for external device control and data export. Optional GPIB (IEEE-488) port enables automated test station integration.
