An automated system for testing an avionics radio

An automated RF measurement suite tests an avionics radio designed to comply with DO-281A specifications. It combines RF test instrumentation, configurable RF signal paths, Labview™ automation and a proprietary PC-based radio manager. Transmit and receive spectral and time domain measurements are performed in the operating band, as well as simulating interferers and measurements of broadband spurious power up to 1.7GHz. The suite reduces production time by 83% thereby lowering costs. It also tests the radio more thoroughly and avoids human error that is a risk in extensive test plans. The system is configurable so that it can be used for design verification and end-item and board level testing in production. The complete suite is portable and cost-efficient and negates the need to hire additional production engineers and open up additional production lines.
