FAQ
- Is the GUXI fully localized?
- The GUXI is designed entirely on domestic chips — 100% localized and self-controllable. Every functional module from the overall architecture down is implemented with mature domestic chips, with design verification ensuring multi-module coordination and synchronization meet requirements — suited to self-controllable avionics ground testing.
- Which signals and buses does the GUXI support?
- With a zero-slot control module + backplane bus + functional modules, the platform integrates 2× GJB289A (1553B), 2× 1394, gigabit Ethernet, 4× CAN, 16× RS422/RS485/RS232 serial, plus 32× AI / 16× AO analog, 20× DI / 28× DO digital, 4× PWM simulation and acquisition each, and 12× PT1000 resistance acquisition and simulation each — combined to suit customized test plans.
- What are the GUXI’s size and environmental ratings?
- The unit is kept within 300×200×200 mm in a portable compact cage chassis. Wide-temperature -40~85℃ components throughout cover the -20~60℃ operating range and 0~85% humidity requirements; vulnerable areas receive conformal coating, with validation performed in a high/low-temperature chamber simulating real environments.
