03 Terms and definitions

Vehicle immunity

Apply radiated field to the whole vehicle; monitor on-board electronics.

04 Technical requirements

Setup

Vehicle in anechoic/open-area; antenna applies 20 MHz~18 GHz field at levels (e.g. 30 V/m, 100 V/m).

Monitoring

With engine running/key functions active, monitor comms, instruments, controls for failure/degradation.
