Description

When an aircraft is flying in severe convection environment, it will be frequently affected by lightning stroke, which will generate transient induced voltage or current on circuits and cables of airborne equipment, such phenomenon is called indirect lightning effect. It may make the aircraft get out of control, even bring about fuselage fire and other serious accidents. For safety reasons, the airborne equipment must be designed properly and tested completely to ensure the system and equipment with critical safety function to perform normally and its flight security when the aircraft is influenced by lightning stroke.
The LSS 160SM6 and ETS 160MB test systems are designed according to RTCA/DO-160 Section 22, The LSS 160SM6 is capable of generating waveforms 1,4 and 5A/5B, and ETS 160MB is of waveforms 2, 3 and 6. Both test level are from 1 to 5 for pins injection test and cable bundle test; Additionally, the test system is not only meet the test requirement of lightning induced transients conducted susceptibility in MIL-STD-461G CS117, but also the A/B/C/D EUT pulse injection level requirement in GJB 8848: 2016 is satisfied.
The ETS 160MB test system includes various test auxiliary equipment to make it convenient to conduct tests, such as coupling transformer, power blocking device, transient blocking device, pin injection probe, external DC capacitor etc. What’s more, the Corelab software is also available for test remote control, which makes your test easy and convenient.
