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 160SM8 test system is capable of generating waveforms 1,4 and 5A/5B specified in RTCA/DO-160 Section 22, test level is from 1 to 5 for pins injection test and cable bundle test; in addition, the system also meets the A \ B \ C \ D class EUT pulse injection level defined in GJB 8848-2016, as well as multiple related standards such as MIL-STD-461G CS 117 lightning induction transient conduction sensitivity test.
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, external DC capacitor etc. What’s more, the Corelab software is also available for test remote control, which makes your test easy and convenient.
