5. 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 Implementation Regulation for the Voluntary Control of Radio

Interference by Data Processing Equipment and Electronic Office Machines, Section 3.1. The EUT was

placed on a nonmetallic stand in a shielded room 0.8 meters above the ground plane as shown in section 5.3.

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

determine the position producing maximum conducted emissions.

5.2. 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.

6. Test of Radiated Emission Radiated emissions from 30 MHz to 2,000 MHz were measured with a bandwidth of 120 kHz for 30 MHz to

1000 MHz and 1 MHz for above 1GHz according to the methods defines in implementation Regulation for the

Voluntary Control of Radio Interference by Data Processing Equipment and Electronic Office Machines. The

EUT was placed on a nonmetallic stand, 0.8 meter above the ground plane, as shown in section 6.3. The

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

positions producing maximum radiated emissions.

6.2. Test Procedures

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

b. The EUT was set 3/10 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.

h. For testing above 1GHz, the emission level of the EUT in peak mode was 20dB lower than average limit

(that means the emission level in peak mode also complies with the limit in average mode), then testing

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

average mode again and reported.
