a. Conducted Emission
The AMN placed 0,8 m from the boundary of the unit under test and bonded to a
ground reference plane. This distance was between the closest points of the AMN and the EUT.
All other units of the EUT and associated equipment were at least 0,8 m from the AMN. All power was
connected to the system through Artificial Mains Network (AMN). Conducted voltage measurements on
mains lines were made at the output of the AMN.
b. Radiated Emission
Measurements were made in a 10-meter semi-anechoic chamber or Open Area Test Site that
complies to CISPR 16. Preliminary (peak) measurements were performed at an antenna to EUT
separation distance of 10 meter. The EUT was rotated 360° about its azimuth with the receive antenna
located at various heights in horizontal and vertical polarities. Final measurements (quasi-peak) were
then performed by rotating the EUT 360° and adjusting the receive antenna height from 1 to 4 m. All
frequencies were investigated in both horizontal and vertical antenna polarity, where applicable.
c. Harmonic Current
This test consists on the measurement of harmonics components of the input current which may be
produced by equipment having an input current up to and including 16 A per phase, and intended to
be connected to public low-voltage distribution systems. The equipment is tested under specified
conditions of operation.
d. Voltage Fluctuations and Flicker
The test circuit consists of a test supply voltage, reference impedance, the equipment under test and a
flicker meter compliant with IEC 60868. The equipment shall be tested in the condition in which the
manufacturer supplies it.
e. Electrostatic Discharge
The test is intended to demonstrate the immunity of equipment subjected to static electricity discharges
from operators directly and to adjacent objects. The tabletop equipment under test is placed on a wooden
table, 0.8m high, standing on the ground reference plane. A horizontal coupling plane (HCP), 1.6 x 0.8
m, is placed on the table. The EUT and the cables are isolated from the coupling plane by an insulating
support 0.5 mm thick. The floor standing equipment is isolated from the ground reference plane by an
insulating support about 0.1 m thick. The vertical coupling plane (VCP) of dimensions 0.5 m x 0.5 m is
placed parallel to, and positioned at a distance of 0.1 m from, the EUT.
f. Radiated RF Immunity
The test allows estimating of the radiated immunity of electrical and electronic equipment to
electromagnetic disturbances coming from intended radio-frequency (RF) transmitters in the frequency
range 80 MHz to 2500 MHz. The interference is applied on the enclosure of the equipment by using
transmitting antennas.
g. Electrical Fast Transient/Burst immunity
Measurements were made on a ground plane that extends 1-meter minimum beyond all sides of
the system under test. Mains power tests were conducted with the product connected to a
Coupling/Decoupling Network (CDN). I/O lines were tested in a Capacitive Coupling Clamp. One of each
unique interface was tested for a period of one (1) minute per polarity.
h. Surge Immunity
Measurements were made on a ground plane that extends 1-meter minimum beyond all sides of
the system under test. Mains power tests were conducted with the product connected to a
Coupling/Decoupling Network (CDN). I/O lines were tested in a Capacitive Coupling Clamp. One of each
unique interface was tested for a period of one (1) minute per polarity.
i. Conducted RF Immunity
Measurements were made on a ground plane that extends 0.5-meter minimum beyond all sides of the
system under test. The EUT was located 10cm above the reference ground plane and any associated
I/O cables attached to the EUT were located between 30mm and 50mm above the ground plane. The
indicated field was pre-calibrated prior to placement of the system under test.
