Test Setup with BCI
When using a clamp injection and common mode impedance requirements
cannot be met at the AE side, it is necessary that the common mode
impedance of the AE is less than or equal to the common mode impedance
of the EUT port being tested. If not, measures shall be taken, e.g. by using
decoupling at the AE port, to satisfy this condition.
By means of an extra current probe, inserted in between the injection clamp
and the EUT, the current resulting from the inducted voltage shall be
monitored. If the current exeeds the short circuit value I
max
given below, the
test generator level shall reduced until the measured current is equal to the
I
max
value.
