Attenuation 10 dB
Start Frequency 0.15 MHz
Stop Frequency 30 MHz
IF Bandwidth 9 KHz
4.1.3. Test Procedures
1. Configure the EUT according to ANSI C63.4. The EUT or host of EUT has to be placed 0.4 meter far
from the conducting wall of the shielding room and at least 80 centimeters from any other
grounded conducting surface.
2. Connect EUT or host of EUT to the power mains through a line impedance stabilization network (LISN).
3. All the support units are connected to the other LISNs. The LISN should provide 50uH/50ohms
coupling impedance.
4. The frequency range from 150 KHz to 30 MHz was searched.
5. Set the test-receiver system to Peak Detect Function and Specified Bandwidth with Maximum Hold
Mode.
6. The measurement has to be done between each power line and ground at the power terminal.

4.1.4. Test Setup Layout
Report No.: FR660211
1. If cables, which hang closer than 40 cm to the horizontal metal groundplane, cannot be shortened
to appropriate length, the excess shall be folded back and forth forming a bundle 30 cm to 40 cm
long.
2. Excess mains cord shall be bundled in the centre or shortened to appropriate length.
3. EUT is connected to one artificial mains network (AMN). All AMNs and ISNs may alternatively be
connected to a vertical reference plane or metal wall.
4. All other units of a system are powered from a second AMN. A multiple outlet strip can be used for
multiple mains cords.
5. AMN and ISN are 80 cm from the EUT and at least 80 cm from other units and other metal planes.
6. Mains cords and signal cables shall be positioned for their entire lengths, as far as possible, at 40 cm
from the vertical reference plane.
7. Cables of hand operated devices, such as keyboards, mouses, etc. shall be placed as for normal
usage.
8. Peripherals shall be placed at a distance of 10 cm from each other and from the controller, except
for the monitor which, if this is an acceptable installation practice, shall be placed directly on the
top of the controller.
9. I/O signal cable intended for external connection.
10. The end of the I/O signal cables which are not connected to an AE may be terminated, if required,
using correct terminating impedance.
11. If used, the current probe shall be placed at 0,1 m from the ISN.

4.5. Radiated Emissions Measurement
4.5.1. Limit
20dBc in any 100 kHz bandwidth outside the operating frequency band. In case the emission fall within
the restricted band specified on 15.205(a), then the 15.209(a) limit in the table below has to be
followed.

4.5.3. Test Procedures
1. Configure the EUT according to ANSI C63.4. The EUT was placed on the top of the turntable 0.8
meter above ground. The phase center of the receiving antenna mounted on the top of a
height-variable antenna tower was placed 3 meters far away from the turntable.
2. Power on the EUT and all the supporting units. The turntable was rotated by 360 degrees to
determine the position of the highest radiation.
3. The height of the broadband receiving antenna was varied between one meter and four meters
above ground to find the maximum emissions field strength of both horizontal and vertical
polarization.
4. For each suspected emissions, the antenna tower was scan (from 1 M to 4 M) and then the turntable
was rotated (from 0 degree to 360 degrees) to find the maximum reading.
Report No.: FR660211
5. Set the test-receiver system to Peak or CISPR quasi-peak Detect Function with specified bandwidth
under Maximum Hold Mode.
6. For emissions above 1GHz, use 1MHz VBW and RBW for peak reading. Then 1MHz RBW and 10Hz VBW
for average reading in spectrum analyzer.
7. When the radiated emissions limits are expressed in terms of the average value of the emissions, and
pulsed operation is employed, the measurement field strength shall be determined by averaging
over one complete pulse train, including blanking intervals, as long as the pulse train does not
exceed 0.1 seconds. As an alternative (provided the transmitter operates for longer than 0.1
seconds) or in cases where the pulse train exceeds 0.1 seconds, the measured field strength shall
be determined from the average absolute voltage during a 0.1 second interval during which the
field strength is at its maximum value.
8. If the emissions level of the EUT in peak mode was 3 dB lower than the average 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 for below 1GHz.
9. For testing above 1GHz, the emissions level of the EUT in peak mode was lower than average limit
(that means the emissions 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.
10. In case the emission is lower than 30MHz, loop antenna has to be used for measurement and the
recorded data should be QP measured by receiver. High – Low scan is not required in this case.
