Band EDGE test
7.1 Measurement Procedure
The EUT was placed on a styrofoam table which is 1.5m above ground plane.
The measurement procedure at the ban edges was simplified by performing the
measurement in just one plot. Both, the in-band-emission and the unwanted emission were
be encompassed by the span. After trace stabilization, the maximum peak was be
determined by a peak detector and the value was marked by an appropriate limit line. The
second limit line, which is 20dB below the first, marks the limit for the emissions in the
unrestricted band. A maximum-peak-detector marks the highest emission in the
unrestricted band next to the band edge.
The measurements were performed at the lower end of the 2.4GHz band.

Radiated Emission Test
8.1 Measurement Procedure
1. Below 1000MHz, The EUT was placed on a turn table which is 0.8m above ground
plane. And above 1000MHz, The EUT was placed on a styrofoam table which is 1.5m
above ground plane.
2. The EUT was set 3 meters from the interference receiving antenna, which was
mounted on the top of a variable height antenna tower.
3. For each suspected emission, the EUT was arranged to its worst case and then tune
the Antenna tower (From 1m to 4m) and turntable (from 0 degree to 360 degree) to
find the maximum reading. A pre-amp and a high pass filter are used for the test in
order to get better signal level to comply with the guidelines.
4. Set to the maximum power setting and enable the EUT transmit continuously.
5. Final measurement (Above 1GHz): The frequency range will be divided into different
sub ranges depending of the frequency range of the used horn antenna. The EMI
Receiver set to peak and average mode and a resolution bandwidth of 1MHz. The
measurement will be performed in horizontal and vertical polarization of the
measuring antenna and while rotating the EUT in its vertical axis in the range of 0
degree to 360 degree in order to have the antenna inside the cone of radiation.
6. Test Procedure of measurement (For Above 1GHz):
1) Monitor the frequency range at horizontal polarization and move the antenna over
all sides of the EUT(if necessary move the EUT to another orthogonal axis).
2) Change the antenna polarization and repeat 1) with vertical polarization.
3) Make a hardcopy of the spectrum.
4) Measure the frequency of the detected emissions with a lower span and resolution
bandwidth to increase the accuracy and note the frequency value.
5) Change the analyser mode to Clear/ Write and found the cone of emission.
6) Rotate and move the EUT, so that the measuring distance can be enlarged to 3m
and the antenna will be still inside the cone of emission.
7) Measure the level of the detected frequency with the correct resolution bandwidth,
with the antenna polarization and azimuth and the peak and average detector,
which causes the maximum emission.
8) Repeat steps 1) to 7) for the next antenna spot if the EUT is larger than the
antenna beamwidth.

Other harmonics emissions are lower than 20dB below the allowable limit.
Note:
(1) All Readings are Peak Value and AV.
(2) Emission Level= Reading Level+ Probe Factor +Cable Loss.
(3) The average measurement was not performed when the peak measured data
under the limit of average detection.
(4) Measuring frequencies from 1GHz to 25GHz.

9. Antenna requirement
9.1 Limit
Except for special regulations, the Low-power Radio-Frequency Devices must not be
equipped with any jacket for installing an antenna with extension cable. 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 shall be considered sufficient to comply
with the provisions of this section. The manufacture may design the unit so that the user can
replace a broken antenna, but the use of a standard antenna jack or electrical connector is
prohibited.
9.2 Result
The EUT’s antenna, permanent attached antenna, used a Internal antenna, The antenna’s
gain is 0 dBi and meets the requirement.
