Solution For BCI Applications

For conducted immunity tests, EMC labs require a test signal source driven at high RF powers and at defined frequencies. Rohde&Schwarz offers a compact solution with a signal generator, an RF solid-state amplifier with power up to 350 W, power sensors, and test software for the frequency range from 4 kHz to 400 MHz.

Your task

Bulk current injection (BCI) is a conducted immunity test method in line with ISO11452-1 and ISO11452-4. A current injection probe is used to induce current (disturbance) in the wiring harness of the device under test (DUT). The ISO11452-4 standard specifies two BCI test methods: the substitution method and the closed loop method.
