7 Radiated Emissions in restricted frequency bands
Test result: Pass

7.1 Limit
The radiated emissions which fall in the restricted bands, must also comply with the radiated emission
limits specified showed as below:

Frequencies Field Strength Measurement Distance
(MHz) (microvolts/meter) (meters)
0.009 ~ 0.490 2400/F(kHz) 300
0.490 ~ 1.705 24000/F(kHz) 30
1.705 ~ 30.0 30 30
30 ~ 88 100 3
88 ~ 216 150 3
216 ~ 960 200 3
Above 960 500 3

7.2 Measurement Procedure
For Radiated emission below 30MHz:

a) The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meters
chamber room. The table was rotated 360 degrees to determine the position of the highest
radiation.
b) The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on
the top of a variable-height antenna tower.
c) Both X and Y axes of the antenna are set to make the measurement.
d) For each suspected emission, the EUT was arranged to its worst case and the rotatable table was
turned from 0 degrees to 360 degrees to find the maximum reading.
e) The test-receiver system was set to Quasi-Peak Detect Function and Specified Bandwidth with
Maximum Hold Mode.
NOTE:
1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 9kHz at
frequency below 30MHz.

Report No.: 190400902SHA-001

TEST REPORT

For Radiated emission above 30MHz:

a) The EUT was placed on the top of a rotating table 0.8 meters (for 30MHz ~ 1GHz) / 1.5 meters (for
above 1GHz) above the ground at 3 meters chamber room for test. The table was rotated 360
degrees to determine the position of the highest radiation.
b) The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on
the top of a variable-height antenna tower.
c) The height of antenna 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.
d) 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 and the rotatable table was turned from 0 degrees to 360
degrees to find the maximum reading.
e) The test-receiver system was set to peak or quasi-peak detect function and specified bandwidth
with maximum hold mode when the test frequency is below 1 GHz.
f) The test-receiver system was set to peak and average detector function and specified bandwidth
with maximum hold mode when the test frequency is above 1 GHz. If the peak reading value also
meets average limit, measurement with the average detector is unnecessary.

Note:
1. The resolution bandwidth of test receiver/spectrum analyzer is 120kHz for peak or quasi-peak
detection at frequency below 1GHz.
2. The resolution bandwidth of test receiver/spectrum analyzer is 1 MHz at frequency above
1GHz for peak detection above 1GHz.
3. The resolution bandwidth of test receiver/spectrum analyzer is 1 MHz and the video
bandwidth is ≥ 1/T (Duty cycle < 98%) or 3 x RBW (Duty cycle ≥ 98%) for average detection (AV)
at frequency above 1GHz.
4. All modes of operation were investigated and the worst-case emissions are reported.

Remark: 1. Correct Factor = Antenna Factor + Cable Loss (- Amplifier, for higher than 1GHz), the value
was added to Original Receiver Reading by the software automatically.
2. Corrected Reading = Original Receiver Reading + Correct Factor
3. Margin = Limit - Corrected Reading
4. If the PK Corrected Reading is lower than AV limit, the AV test can be elided.

TEST REPORT
Example: Assuming Antenna Factor = 30.20dB/m, Cable Loss = 2.00dB,
Gain of Preamplifier = 32.00dB, Original Receiver Reading = 10.00dBuV,
Limit = 40.00dBuV/m.
Then Correct Factor = 30.20 + 2.00 – 32.00 = 0.20dB/m;
Corrected Reading = 10dBuV + 0.20dB/m = 10.20dBuV/m;
Margin = 40.00dBuV/m - 10.20dBuV/m = 29.80dB.

8.3 Measurement Procedure
Measured levels of ac power-line conducted emission shall be the emission voltages from the voltage
probe, where permitted, or across the 50 Ω LISN port (to which the EUT is connected), where permitted,
terminated into a 50 Ω measuring instrument. All emission voltage and current measurements shall be
made on each current-carrying conductor at the plug end of the EUT power cord by the use of mating
plugs and receptacles on the LISN, if used. Equipment shall be tested with power cords that are normally
supplied or recommended by the manufacturer and that have electrical and shielding characteristics
that are the same as those cords normally supplied or recommended by the manufacturer. For those
measurements using a LISN, the 50 Ω measuring port is terminated by a measuring instrument having
50 Ω input impedance. All other ports are terminated in 50 Ω loads.

Tabletop devices shall be placed on a platform of nominal size 1 m by 1.5 m, raised 80 cm above the
reference ground plane. The vertical conducting plane or wall of an RF-shielded (screened) room shall
be located 40 cm to the rear of the EUT. Floor-standing devices shall be placed either directly on the
reference ground-plane or on insulating material as described in ANSI C63.4. All other surfaces of
tabletop or floor-standing EUTs shall be at least 80 cm from any other grounded conducting surface,
including the case or cases of one or more LISNs.

The bandwidth of the test receiver is set at 9 kHz.

9 Occupied Bandwidth
Test result: Tested

9.1 Limit
None

9.2 Measurement Procedure
The occupied bandwidth was measured using the Spectrum Analyzer.

The span of the analyzer shall be set to capture all products of the modulation process, including the
emission skirts.

The resolution bandwidth (RBW) shall be in the range of 1% to 5% of the occupied bandwidth (OBW)
and video bandwidth (VBW) shall be approximately 3x RBW.

9.3 Test Configuration

EUT Spectrum Analyzer

9.4 The results of Occupied Bandwidth

TEST REPORT

10 Antenna requirement
Requirement:
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.

Result:
EUT has two types of antenna. The PCB antenna is permanently attached. The Pole antenna employs a
unique antenna connector RP-SMA to the intentional radiator. So the EUT can comply with the
provisions of this section.
