Overview of BCI Test Setup

When using clamp injection, the AE setup shall present the common mode impedance as
required in 6.2.1 as closely as possible (see Annex H). Each AE used with clamp injection
shall represent the functional installation conditions as closely as possible. To approximate
the required common mode impedance the following measures need to be taken.
– Each AE, used with clamp injection, shall be placed on an insulating support 0,1 m above
the reference ground plane.
– The clamp shall be placed on the cable to be tested. The clamp shall be supplied with the
test generator level previously established during the level setting procedure.
– During a test, a ground connection shall be made from the screen of the input port of the
current injection clamp or from the earth bar of the EM clamp, to the reference ground
plane (see Figures 14 and 15).
– A decoupling network shall be installed on each cable between the EUT and AE except
the cable under test.
– All cables connected to each AE, other than those being connected to the EUT, shall be
provided with decoupling networks, see 6.2.5 and Figure 5.
– The decoupling networks connected to each AE (except those on cables between the EUT
and AE) shall be applied no further than 0,3 m from the AE (distance: L2). The cable(s)
between the AE and the decoupling network(s) or in between the AE and the injection
clamp shall not be bundled nor wrapped and shall be kept at a height of 30 mm or more
above the reference ground plane (Figure 5).
– At one end of the cable under test is the EUT, and at the opposite end is the AE. Multiple
CDNs can be connected to the EUT and to the AE; however, only one CDN on each of the
EUT and AE shall be terminated in 50 :. The termination of the CDN shall be chosen
according to the priority in 7.5.
– When several clamps are used, the injection is carried out on each cable selected for
testing one by one. The cables which are selected for testing with the injection clamp but
not actually exercised shall be decoupled in accordance with 6.2.5.

When using clamp injection, and the common mode impedance requirements cannot be met at the AE side, it is necessary that the common mode impedance of the AE be 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 a CDN-M1 or 150 : resistor from the AE to ground) at the AE port to satisfy this condition and to prevent resonances. In this procedure, only the relevant differences with those measures mentioned in 7.6 are given.

– Each AE and EUT used with clamp injection shall represent the functional installation
conditions as closely as possible, e.g. the EUT shall either be connected to the reference
ground plane or placed on an insulating support (see Figures 14 and 15).

– By means of a current monitoring probe (having low insertion loss), inserted in between
the injection clamp and the EUT, the current resulting from the induced voltage (set
according to 6.4.1) shall be monitored. If the current exceeds the nominal circuit value
Imax given below, the test generator level shall be reduced until the measured current is
equal to the Imax value:
