For Conducted RF test setup
4.5 SYSTEM TEST CONFIGURATION
For emissions testing, the equipment under test (EUT) setup to transmit continuously to simplify the
measurement methodology. Care was taken to ensure proper power supply voltages during testing. During
testing, radiated emission were performed with the EUT set to transmit at the channel with highest output power
as worst-case scenario. It was powered by a 3.7Vdc rechargeable Li-on battery. Only the worst case data were
recorded in this test report.
The signal is maximized through rotation and placement in the three orthogonal axes. The antenna height and
polarization are varied during the search for maximum signal level. The antenna height is varied from 1 to 4
meters. Radiated emissions are taken at three meters unless the signal level is too low for measurement at that
distance. If necessary, a pre-amplifier is used and/or the test is conducted at a closer distance. Therefore, all
final radiated testing was performed with the EUT in (see table below) orientation.

All readings are extrapolated back to the equivalent three meter reading using inverse scaling with distance.
Analyzer resolution is 100 kHz or greater for frequencies below 1000 MHz. The resolution is 1 MHz or greater
for frequencies above 1000 MHz. The spurious emissions more than 20 dB below the permissible value are not
reported.
Radiated emission measurement were performed from the lowest radio frequency signal generated in the
device which is greater than 9 kHz to the tenth harmonic of the highest fundamental frequency or to 40 GHz,
whichever is lower.

An intentional radiator shall be designed to ensure that no antenna other than that furnished by the
responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna
that uses a unique coupling to the intentional radiator, the manufacturer may design the unit so that a broken
antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is
prohibited.
15.247(b) (4) requirement:
The conducted output power limit specified in paragraph (b) of this section is based on the use of antennas
with directional gains that do not exceed 6 dBi. Except as shown in paragraph (c) of this section, if
transmitting antennas of directional gain greater than 6 dBi are used, the conducted output power from the
intentional radiator shall be reduced below the stated values in paragraphs (b)(1), (b)(2), and (b)(3) of this

Remark:

2. Emission level (dBuV/m) = 20 log Emission level (uV/m).
3. For frequencies above 1000 MHz, the field strength limits are based on average detector, however, the
peak field strength of any emission shall not exceed the maximum permitted average limits, specified
above by more than 20 dB under any condition of modulation.
Test Setup:
Refer to section 4.4.1 for details.
Test Procedures:
1. From 30 MHz to 1GHz test procedure as below:
1) The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter semi-anechoic
camber. The table was rotated 360 degrees to determine the position of the highest radiation.
2) The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top
of a variable-height antenna tower.
3) 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.
4) 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 1 meter) and the rota table table was turned from 0 degrees to 360 degrees to find the maximum
reading.
5) The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold
Mode.
6) 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.
2. Above 1GHz test procedure as below:
1) Different between above is the test site, change from Semi- Anechoic Chamber to fully Anechoic Chamber
and change form table 0.8 meter to 1.5 meter( Above 18GHz the distance is 1 meter and table is 1.5
meter).
2) Test the EUT in the lowest channel ,middle channel, the Highest channel
3) The radiation measurements are performed in X, Y, Z axis positioning for Transmitting mode, and found

Test Setup:
Refer to section 4.4.1 for details.
Test Procedures:
Radiated band edge measurements at 2390 MHz and 2483.5 MHz were made with the unit transmitting in the
low end of the channel range and the high end closest to the restricted bands respectively. The emissions
were made on the 966 Semi-Chamber. Use (resolution bandwidth (RBW) = 1 MHz, video bandwidth (VBW) =
3 MHz for peak levels and RBW = 1 MHz and VBW = 10 Hz or 1/T for average levels).
1. Use radiated spurious emission test procedure described in clause 5.10. The transmitter output (antenna
port) was connected to the test receiver.
2. Set the PK and AV limit line.
3. Record the fundamental emission and emissions out of the band-edge.
4. Determine band-edge compliance as required.
Equipment Used:
Refer to section 3 for details.
Test Result:
Pass

Remark:
1. The lower limit shall apply at the transition frequencies.
2. The limit decreases linearly with the logarithm of the frequency in the range 0.15 to 0.50 MHz.
Test Setup:
Refer to section 4.4.2 for details.
Test Procedures:
Test frequency range :150KHz-30MHz
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 50Ω/50µH + 5Ω 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.
Equipment Used:
Refer to section 3 for details.
