3. Test of Conducted Powerline

Conducted Emissions were measured from 150 kHz to 30 MHz with a bandwidth of 9 kHz and return leads

of the EUT according to the methods defined in European Standard EN 301 489-17. The EUT was placed

on a nonmetallic stand in a shielded room 0.8 meters above the ground plane as shown in section 2.2.

The interface cables and equipment positioning were varied within limits of reasonable applications to

determine the position producing maximum conducted emissions.

3.1. Test Procedures

a. The EUT was placed on a desk 0.8 meters height from the metal ground plane and 0.4 meter from

the conducting wall of the shielding room and it was kept at least 0.8 meters from any other

grounded conducting surface.

b. Connect EUT to the power mains through a line impedance stabilization network (LISN).

c. All the support units are connect to the other LISN.

d. The LISN provides 50 ohm coupling impedance for the measuring instrument.

e. The CISPR states that a 50 ohm , 50 microhenry LISN should be used.

f. Both sides of AC line were checked for maximum conducted interference.

g. The frequency range from 150 kHz to 30 MHz was searched

h. Set the test-receiver system to Peak Detect Function and Specified Bandwidth with Maximum Hold

Mode.

3.2. Typical Test Setup Layout of Conducted Powerline

3.3. Conducted Emission Requirement

The equipment under test EUT）shall meet the limits in table 1and 3 or 2 and 4,as applicable,

including the average limit and the quasi-peak limit when using,repectively, an average detector

receiver and quasi-peak detector receiver and measured in accordance with the methods

described in clause 9. Either the voltage limits or the current limits in table 3 or 4, as applicable,

shall be met except for the measurement method of C.1.3 where both limits shall be met. If the

average limit is met when using a qusai-peak decetor reciver, the EUT shall be deemeed to meet

both limits and measurement with the average detector receiver is unnecessary.

If the reading of the measuring receiver shows fluctuations close to the limit, the reading shall be

observed for at least 15 s at each measurement frequency, the higher reading shall be recorded

with the exception of any brief isolated hith reading which shall be ignored.

4. Test of Radiated Emission

Radiated emissions from 30 MHz to 1000 MHz were measured with a bandwidth of 120 kHz according to

the methods defines in European Standard EN 301 489-17. The EUT was placed on a nonmetallic

stand in the open-field site, 0.8 meter above the ground plane, as shown in section 3.2. The interface

cables and equipment positions were varied within limits of reasonable applications to determine the

positions producing maximum radiated emissions.

4.1. Test Procedures

a. The EUT was placed on a rotatable table top 0.8 meter above ground.

b. The EUT was set 10 meters from the interference receiving antenna which was mounted on

the top of a variable height antenna tower.

c. The table was rotated 360 degrees to determine the position of the highest radiation.

d. The antenna is a half wave dipole and its height is varied between one meter and four meters

above ground to find the maximum value of the field strength both horizontal polarization and

vertical polarization of the antenna are set to make the measurement.

e. For each suspected emission the EUT was arranged to its worst case and then tune the

antenna tower (from 1 M to 4 M) and turn table (from 0 degree to 360 degrees) to find the

maximum reading.

f. Set the test-receiver system to Peak Detect Function and specified bandwidth with Maximum

Hold Mode.

g. If the emission level of the EUT in peak mode was 3 dB lower than the limit specified, then

testing will be stopped and peak values of EUT will be reported, otherwise, the emissions

which do not have 3 dB margin will be repeated one by one using the quasi-peak method and

reported.
