Cables and wiring harnesses in automobiles function as antennas
with which many types of transmissions (radio, TV, mobile phone,
Bluetooth, etc.) can disturb or aect electronics in the vehicle. With
the CWS N in a clearly arranged test set-up you can generate
narrow-band interference signals that are induced via BCI current-
injection using the substitution or closed loop method. The BCI
clamp is a current transformer that is positioned around the wiring
harness. In the substitution method, the disturbance signal is calibra-
ted in a dened calibration circuit and the level is saved and used
during the testing. In the closed loop method, the disturbance current
is measured with the internal measurement instrument. The control
algorithm calculates the output signal and controls the disturbance
signal at the required level.
The BCI testing method is used in automotive, military and aerospace
testing to ensure the immunity of individual components in complex
systems.
