Figure 1: BCI test setup and the injection probe. The injection probe is a current transformer through which the wiring harness which forms the secondary winding of the device under test DUT is passed. Immunity tests are carried out by varying the test severity level and frequency 1 MHz — MHz of the induced disturbance. The disturbance is an amplitude modulated AM , narrowband, continuous wave CW carrier signal. The ISO standard specifies two BCI test methods: the substitution open-loop , and current monitoring closed-loop probe methods.

This document specifies harness excitation test methods and procedures for determining the immunity of electronic components of passenger cars and commercial vehicles regardless of the propulsion system e. The bulk current injection BCI test method is based on current injection into the wiring harness using a current probe as a transformer where the harness forms the secondary winding. The tubular wave coupler TWC test method is based on a wave coupling into the wiring harness using the directional coupler principle.

It is best suited to small with respect to wavelength and shielded device under test DUT , since in these cases the dominating coupling mechanism is via the harness.
