4.2.2 TEST PROCEDURES
Procedure of Preliminary Test
For measurement of the disturbance voltage the equipment under test (EUT) is connected to
the power supply mains and any other extended network via one or more artificial network(s).
An EUT, whether intended to be grounded or not, and which is to be used on a table is
configured as follows:
the power supply mains and any other extended network via one or more artificial network(s).
An EUT, whether intended to be grounded or not, and which is to be used on a table is
configured as follows:
– Either the bottom or the rear of the EUT shall be at a controlled distance of 40 cm from a
reference ground plane. This ground plane is normally the wall or floor of a shielded room. It
may also be a grounded metal plane of at least 2 m by 2 m. This is physically accomplished as
follows:
reference ground plane. This ground plane is normally the wall or floor of a shielded room. It
may also be a grounded metal plane of at least 2 m by 2 m. This is physically accomplished as
follows:
1) place the EUT on a table of non-conducting material which is at least 80 cm high. Place the
EUT so that it is 40 cm from the wall of the shielded room, or
EUT so that it is 40 cm from the wall of the shielded room, or
2) place the EUT on a table of non-conducting material which is 40 cm high so that the
bottom of the EUT is 40 cm above the ground plane;
bottom of the EUT is 40 cm above the ground plane;
– All other conductive surfaces of the EUT shall be at least 80 cm from the reference ground
plane;

– The ANs are placed on the floor that one side of the AN housings is 40 cm from the
vertical reference ground plane and other metallic parts;
vertical reference ground plane and other metallic parts;
– Interconnecting cables that hang closer than 40 cm to the ground plane shall be folded
back and forth forming a bundle 30 cm to 40 cm long, hanging approximately in the middle
between the ground plane and the table.
back and forth forming a bundle 30 cm to 40 cm long, hanging approximately in the middle
between the ground plane and the table.
– I/O cables that are connected to a peripheral shall be bundled in the centre. The end of the
cable may be terminated if required using correct terminating impedance. The total length
shall not exceed 1 m.
The test mode(s) described in Item 2.4 were scanned during the preliminary test. After the
preliminary scan, we found the test mode described in Item 2.4 producing the highest
emission level. The EUT configuration and cable configuration of the above highest emission
cable may be terminated if required using correct terminating impedance. The total length
shall not exceed 1 m.
