6.1.3 Measurement Procedure and Data
1) The mains terminal disturbance voltage test was conducted in a shielded room.
2) The EUT was connected to AC power source through a LISN 1 (Line Impedance Stabilization
Network) which provides a 50ohm/50µH + 5ohm linear impedance. The power cables of all other
units of the EUT were connected to a second LISN 2, which was bonded to the ground reference
plane in the same way as the LISN 1 for the unit being measured. A multiple socket outlet strip was
used to connect multiple power cables to a single LISN provided the rating of the LISN was not
exceeded.
3) The tabletop EUT was placed upon a non-metallic table 0.8m above the ground reference plane.
And for floor-standing arrangement, the EUT was placed on the horizontal ground reference plane,
4) The test was performed with a vertical ground reference plane. The rear of the EUT shall be 0.4 m
from the vertical ground reference plane. The vertical ground reference plane was bonded to the
horizontal ground reference plane. The LISN 1 was placed 0.8 m from the boundary of the unit under
test and bonded to a ground reference plane for LISNs mounted on top of the ground reference
plane. This distance was between the closest points of the LISN 1 and the EUT. All other units of the
EUT and associated equipment was at least 0.8 m from the LISN 2.
5) In order to find the maximum emission, the relative positions of equipment and all of the interface
cables must be changed according to ANSI C63.10 on conducted measurement.

6.2.3 Measurement Procedure and Data
Test Procedure: a. The EUT was placed on the top of a rotating table 0.8 meters above the
ground at a 3 meter semi-anechoic chamber(30MHz-1000MHz) and 3 meter
semi-anechoic chamber(9kHz-30MHz). The table was rotated 360 degrees to
determine the position of the highest radiation.
b. The EUT was set 10 meters(30MHz-1000MHz) and 10 meter (9kHz-30MHz)
away from the interference-receiving antenna, which was mounted on the top
of a variable-height antenna tower.
c. Above 30MHz: The Analyzer/Receiver scanned from 30MHz to 1000MHz.The
antenna height is varied from one meter to four meters above the ground to
determine the maximum value of the field strength. Both horizontal and
vertical polarizations of the antenna are set to make the measurement.
d. Below 30MHz: The Analyzer/Receiver scanned from 9kHz to 30MHz.The
antenna height is 2 meters above the ground to determine the maximum

Report No.: SZEM190301137601
Page: 14 of 17
value of the field strength.
e. For each suspected emission, the EUT was arranged to its worst case and
then the antenna was tuned to heights from 1 meter to 4 meters (for the test
frequency of below 30MHz, the antenna was tuned to heights 2 meter) and
the rotatable table was turned from 0 degrees to 360 degrees to find the
maximum reading.
f. The test-receiver system was set to Peak Detect Function and Specified
Bandwidth with Maximum Hold Mode.
g. If the emission level of the EUT in peak mode was 10dB lower than the limit
specified, then testing could be stopped and the peak values of the EUT
would be reported. Otherwise the emissions that did not have 10dB margin
would be re-tested one by one using peak, quasi-peak or average method as
specified and then reported in a data sheet.
h. Repeat above procedures until all frequencies measured was complete.
i. Measurement Requirement:
1)This product belongs to non-ISM equipment, the field strength limit is 15uV/m at
300 meter distance.
2)Limit: 20log(15uV/m) +20log (300/3) =23.52+40=63.52dBuV/m at 3 meters
distance.
