BCI(Bulk Current Injection) Test Features Bulk current injection into wire. Capable of evaluating individual noise intrusion into low impedance circuit. Detail ｏｆ　Ｔｅｓｔ　Ｍｅｔｈｏｄ 　Table1 Detail of Test Method Variation Frequency Injection Current Modulation All terminals at once, each wire harness branch and each circuit (open collector circuit, feedback circuit for voltage and current, each GND). 1～400MHz Lump sum input：200mA Individual input：160mA ＣＷ，ＡＭ Test Bench Preparation Test bench shall be basically equal to actual vehicle setting, facilities used for testing shall be as follows. Carry out the test in standard conditions and at standard voltages, unless otherwise specified. (1)Simulator Use a simulator to monitor the state of specimen actuation and to apply a proper load equivalent to that on the vehicle. The configuration of the simulator shall meet the specifications of each specimen. Use a simulator to which countermeasures (such as insertion of ferrite core, storage into shield case, use of optical fiber for communication line with monitor portion) are implemented to have resistance against electromagnetic interference. Sub wire harness Use a sub-wire harness to connect the specimen, simulator and the power supply. The type and diameter of the cable for the sub-wire harness shall be equivalent to that on the vehicle. If there are some other specifications for a particular specimen, follow the specifications. (a) If W/H is protected from noise using shielding wire etc., incorporate the condition in the test bench. (b) The length of the sub-W/H shall be the same as in the actual vehicle. Otherwise, artificial network (AN) may be connected 1 to 1.5 m from the test specimen to reduce the effect due to interference between power supplies. (3)Artificial network; AN The power shall be supplied to the specimen through the artificial network (AN) with the circuit configuration shown in Fig. 1. The impedance characteristics shall not deviate more than 20
