In Progress

Layout

A hardware-in-the-loop platform designed to electrically emulate the sensors, actuators, and interfaces used by the flight avionics system. The board combines programmable RTD, thermocouple, pressure-transducer, current-loop, and differential-sensor channels with valve and deployment-load interfaces, ADC and DAC conversion, multi-rail power, Compute Module 5 control, and wired communication interfaces.

Design Focus

  • Reproduce the electrical behavior of multiple flight sensors from one configurable platform
  • Generate low-noise analog outputs across several signal ranges and interface types
  • Keep switching-power and actuator circuitry from coupling into precision emulation channels
  • Support both automated test control and direct bench access
  • Keep the architecture readable enough for another engineer to follow the validation path quickly

Layout is in progress; this page currently focuses on schematic architecture and planned validation flow.
