Power Main Port Conducted Emissions

2.1 Configuration and Procedure

2.1.1 EUT Configuration

The EUT was set up on the non-conductive table that is 1.0 by 1.5 meter, 80cm above

ground. The wall was 40cm to the rear of the EUT.

Power to the EUT was provided through the LISN. The impedance vs. frequency

characteristic of the LISN is complied with the limit of standards used.

Both lines (neutral and hot) were connected to the LISN in series at testing. A

coaxial-type connector which provides one 50 ohms impedance termination was connected to
the test instrument. The excess length of the power cord was folded back and forth at the center
of the lead to form a bundle 30cm to 40cm in length.

Any changes made to the configuration or modifications made to EUT during testing,

are noted in the following test record.

If EUT has an extra auxiliary AC outlet which can provide power to an external

monitor, all measurements will be made with the monitor power from EUT-mounted AC outlet
and then from floor-mounted AC outlet.

2.1.2 Test Procedure

The system was set up as described above, with the EMI diagnostic software running.

The main power line conducted EMI tests were run on both hot and neutral conductors of the
power cord and the results were recorded. The effect of varying the position of the interface
cables has been investigated to find the configuration that produces maximum emission.

At the frequencies where the peak values of the emissions were higher than 6dß below

the applicable limits, the emissions were also measured with the quasi-peak detectors. At the
frequencies where the quasi-peak values of the emissions were higher than 6dß below the
applicable average limits, the emissions were also measured with the average detectors.

The highest emissions were analyzed in details by operating the spectrum analyzer in

fixed tuned mode to determine the nature of the emissions and to provide information which
could be useful in reducing their amplitude.

Radiated Disturbance Emissions

3.1 Configuration and Procedure

3.1.1 EUT Configuration

The equipment under test was set up on a non-conductive table 80cm above ground,

on a open field or chamber. The excess length of the power cord was folded back and forth at the
center of the lead to form a bundle 30cm to 40cm in length.

Any changes made to the configuration, or modifications made to the EUT, during

testing are noted in the following test record.

If EUT has an extra auxiliary AC outlet which can provide power to an external

monitor, all measurements will be made with the monitor power from EUT-mounted AC outlet
and then from floor-mounted AC outlet.

3.1.2 Test Procedure

The system was set up as described above, with the EMI diagnostic software running.

The maximum emission was measured by varying the height of antenna and then by rotating the
turntable. Both polarization of antenna, horizontal and vertical, were measured.

The highest emissions between 30 MHz to 1000 MHz were analyzed in details by operating

the spectrum analyzer and/or EMI receiver in quasi-peak mode to determine the precise amplitude of
the emissions. While doing so, the interconnecting cables and major parts of the system were moved
around, the antenna height was varied between one and four meters, its polarization was varied
between vertical and horizontal, and the turntable was slowly rotated, to maximize the emission.

Appendix

4.1 Appendix A: Measurement Procedure for Main Power Port Conducted Emissions

The measurements are performed in a 3.5m x 3.4m x 2.5m shielded room, which referred

as Conduction 01 test site, or a 3m x 3m x 2.3m test site, which referred as Conduction 02 test
site. The EUT was placed on non-conduction 1.0m x 1.5m table, which is 0.8 meters above an
earth-grounded.

Power to the EUT was provided through the LISN which has the Impedance

(50ohm/50uH) vs. Frequency Characteristic in accordance with the standard. Power to the
LISNs were filtered to eliminate ambient signal interference and these filters were bonded to the
ground plane. Peripheral equipment required to provide a functional system (support equipment)
for EUT testing was powered from the second LISN through a ganged, metal power outlet box
which is bonded to the ground plane at the LISN.

If the EUT is supplied with a flexible power cord, the power cord length in excess of the

distance separating the EUT from the LISN shall be folded back and forth at the center of the
lead so as to form a bundle not exceeding 40cm in length. If the EUT is provided with a
permanently coiled power cord, bundling of the cord is not required. If the EUT is supplied
without a power cord, the EUT shall be connected to the LISN by a power cord of the type
specified by the manufacturer which shall not be longer than 1 meter. The excess power cord
shall be bundled as described above. If a non-flexible power cord is provided with the EUT, it
shall be cut to the length necessary to attach the EUT to the LISN and shall not be bundled.

The interconnecting cables were arranged and moved to get the maximum measurement.

Both the line of power cord, hot and neutral, were measured.

The highest emissions were analyzed in details by operating the spectrum analyzer in

fixed tuned mode to determine the nature of the emissions and to provide information which
could be useful in reducing their amplitude.

4.2 Appendix B: Test Procedure for Radiated Emissions

Preliminary Measurements in the Anechoic Chamber

The radiated emissions are initially measured in the anechoic chamber at a measurement

distance of 3 meters. Desktop EUT are placed on a wooden stand 0.8 meter in height. The
measurement antenna is 3 meters from the EUT. The test setup in anechoic chamber is the same as
open site. The turntable rotated 360

°C. The antenna height is varied from 1-2.5m. The primary

objective of the radiated measurements in the anechoic chamber is to identify the frequency spectrum
in the absence of the electromagnetic environment existing on the open test site. The frequencies can
then be pre-selected on the open test site to obtain the corresponding amplitude. The initial scan is
made with the spectrum analyzer in automatic sweep mode. The spectrum peaks are then measured
manually to determine the exact frequencies.

Measurements on the Open Site or Chamber

The radiated emissions test will then be repeated on the open site or chamber to measure

the amplitudes accurately and without the multiple reflections existing in the shielded room. The
EUT and support equipments are set up on the turntable. Desktop EUT are set up on a wooden
stand 0.8 meter above the ground.

For the initial measurements, the receiving antenna is varied from 1-4 meter height and is

changed in the vertical plane from vertical to horizontal polarization at each frequency. Both
reading are recorded with the quasi-peak detector with 120KHz bandwidth. For frequency
between 30 MHz and 1000MHz, the reading is recorded with peak detector or quasi-peak
detector.

At the highest amplitudes observed, the EUT is rotated in the horizontal plane while changing

the antenna polarization in the vertical plane to maximize the reading. The interconnecting cables
were arranged and moved to get the maximum measurement. Once the maximum reading is
obtained, the antenna elevation and polarization will be varied between specified limits to maximize
the readings.
