RTCA DO-160 – Section 19.0 – Induced Signal Susceptibility
This test determines whether the equipment interconnect circuit configuration will accept a level of induced voltages caused by the installation environment.
This section relates specifically to interfering signals related to the power frequency and its harmonics, audio frequency signals, and electrical transients that are generated by other on-board equipment or systems and coupled to sensitive circuits within the EUT through its interconnecting wiring.
Power leads tested under Section 18 are exempt from this test.
DO-160 is a standard for environmental test on avionics equipment published by RTCA, the Radio Technical Commission for Aeronautics. The DO 160 G was amended and now all guideline inside it are replaced by the DO 357.
