4.4 SYSTEM TEST CONFIGURATION
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 1000MHz. The resolution is 1 MHz or greater
for frequencies above 1000MHz. 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 (according to KDB 896810 D02 SDoC FAQ v01r01) of
the highest fundamental frequency or to 40 GHz, whichever is lower.

From 30 MHz to 1GHz test procedure as below:
The Product was placed on the non-conductive turntable 0.8 m above the ground at a chamber.
Set the spectrum analyzer/receiver in Peak detector, Max Hold mode, and 120 kHz RBW. Record the
maximum field strength of all the pre-scan process in the full band when the antenna is varied between
1~4 m in both horizontal and vertical, and the turntable is rotated from 0 to 360 degrees.
3) For each frequency whose maximum record was higher or close to limit, measure its QP value: vary the
antenna’s height and rotate the turntable from 0 to 360 degrees to find the height and degree where
Product radiated the maximum emission, then set the test frequency analyzer/receiver to QP Detector
and specified bandwidth with Maximum Hold Mode, and record the maximum value.
2. Above 1GHz test procedure as below:
1) The Product was placed on the non-conductive turntable 0.8 m above the ground at a chamber.
2) Set the spectrum analyzer/receiver in Peak detector, Max Hold mode, and 1MHz RBW. Record the
maximum field strength of all the pre-scan process in the full band when the antenna is varied in both
horizontal and vertical, and the turntable is rotated from 0 to 360 degrees.
3) For each frequency whose maximum record was higher or close to limit, measure its AV value: rotate the
turntable from 0 to 360 degrees to find the degree where Product radiated the maximum emission, then
set the test frequency analyzer/receiver to AV value and specified bandwidth with Maximum Hold Mode,
and record the maximum value.

Remark:
1. As shown in this section, for frequencies above 1GHz, the field strength limits are based on average limits.
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. So, only the peak measurements were
shown in the report.
2. N/A, since there are not any ancillary equipments connected to the radio equipment. The Radiated Emission
test is only applicable to ancillary equipment not incorporated in the radio equipment and intended to be
measured on a stand-alone basis, as declared by the manufacturer.

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 4.3.2 for details.
Test Procedures:
1) The Product was placed on a nonconductive table 0.8 m above the horizontal ground reference plane,
and 0.4 m from the vertical ground reference plane, and connected to the main through Line Impedance
Stability Network (L.I.S.N).
2) The RBW of the receiver was set at 9 kHz in 150 kHz ~ 30MHz with Peak and AVG detector in Max Hold
mode. Run the receiver’s pre-scan to record the maximum disturbance generated from Product in all
power lines in the full band.
3) For each frequency whose maximum record was higher or close to limit, measure its QP and AVG values
and record.
Equipment Used:
Refer to section 3 for details.
Test Result:
Pass
