emission limits in these three bands are based on measurements employing an average detector, 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.

6.1.3 Measurement Procedure and Data
a. For below 1GHz, the EUT was placed on the top of a rotating table 0.8 meters above the ground at
a 3 or 10 meter semi-anechoic chamber. The table was rotated 360 degrees to determine the position
of the highest radiation.
b. For above 1GHz, the EUT was placed on the top of a rotating table 1.5 meters above the ground at
a 3 meter fully-anechoic chamber. The table was rotated 360 degrees to determine the position of the
highest radiation.
c. The EUT was set 3 or 10 meters away from the interference-receiving antenna, which was
mounted on the top of a variable-height antenna tower.
d. 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.
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 1 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. Test the EUT in the lowest channel, the middle channel, the Highest channel.
i. The radiation measurements are performed in X, Y, Z axis positioning for Transmitting mode, and
found the X axis positioning which it is the worst case.
j. Repeat above procedures until all frequencies measured was complete.
Remark 1: Level= Read Level+ Cable Loss+ Antenna Factor- Preamp Factor
Remark 2: 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. For the emissions
whose peak level is lower than the average limit, only the peak measurement is shown in the report.

6.2.3 Measurement Procedure and Data

a 3 or 10 meter semi-anechoic chamber. The table was rotated 360 degrees to determine the position
of the highest radiation.
b. For above 1GHz, the EUT was placed on the top of a rotating table 1.5 meters above the ground at
a 3 meter fully-anechoic chamber. The table was rotated 360 degrees to determine the position of the
highest radiation.
c. The EUT was set 3 or 10 meters away from the interference-receiving antenna, which was
mounted on the top of a variable-height antenna tower.
d. 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.
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 1 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. Test the EUT in the lowest channel, the middle channel, the Highest channel.
i. The radiation measurements are performed in X, Y, Z axis positioning for Transmitting mode, and
found the X axis positioning which it is the worst case.
j. Repeat above procedures until all frequencies measured was complete.
Remark:
1) For emission below 1GHz, through pre-scan found the worst case is the lowest channel. Only the
worst case is recorded in the report.
2) The field strength is calculated by adding the Antenna Factor, Cable Factor & Preamplifier. The
basic equation with a sample calculation is as follows:
Final Test Level =Receiver Reading + Antenna Factor + Cable Factor – Preamplifier Factor
3) Scan from 9kHz to 25GHz, the disturbance above 18GHz and below 30MHz was very low. The
points marked on above plots are the highest emissions could be found when testing, so only above
points had been displayed. The amplitude of spurious emissions from the radiator which are
attenuated more than 20dB below the limit need not be reported.
4) 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. For the emissions whose peak level is
lower than the average limit, only the peak measurement is shown in the report.
