2 SYSTEM TEST CONFIGURATION
2.1 Operation Environment
Temperature : 23℃
Humidity : 60%
Power supply : DC 3.2V
2.2 Justification
The system was configured in typical fashion (as a customer would normally use it) for testing.
2.3 EUT Exercise Software
The EUT exercise program used during radiated testing was designed to exercise
the various system components in a manner similar to typical use.
The sequence is used:
Operation Mode : Transmitting
2.4 Test Procedure
Tabletop Equipment Radiated Emissions
EUT was placed on a platform of nominal size, 1m by 1.5m, raised 80cm above the conducting ground plane.
Test was made with the antenna positioned in both the horizontal and vertical planes of polarization.
The measurement antenna was varied in height above the conducting ground plane to obtain the maximum signal strength.
The measurement distance was 3m.

3.1 Measurement Uncertainty
Radiated Emission Test
The measurement uncertainty (with a 95% confidence level) for this test was ±3.3dB.
■ The data listed in this test report may exceed the test limit because it does not have enough margin (more than 3.3dB).
□ The data listed in this test report has enough margin, more than 3.3dB.

4 RADIATED EMISSION DATA
The initial step in collecting radiated data was a spectrum analyzer peak scan of the measurement range (30MHz-3300MHz).
The final data was reported in the worst-case emissions.
The minimum margin to the limit is as follows :
Receiver Correction Field
Frequency Reading Factor Strength Limit Margin
(MHz) (dBμV) (dBμV) (dBμV/m) (dBμV/m) (dBμV)
315.00 78.2 -3.8 74.4 75.6 1.2
* quasi-peak mode
The Fundamental Frequency of this equipment is 315MHz. The peak of output level of fundamental frequency was
confirmed at the 315MHz by perfarming the meaurement.
It was corroborated that equipment was within of the tolerance which is prescribed
in the FCC requlation Part 15 Subpart C sec. 15.231 (c).
Since the fundamental frequency is 315MHz, the upper limit could be 315.8 MHz and lower limit could be 314.2MHz.
The measurement result was 315.2MHz when the limit was 315.8MHz and also another measurement result was 314.8 MHz
when the limit was 314.2MHz.

5.1 Field Strength Calculation
The field strength is calculated by adding the Antenna Factor, Cable Factor and Antenna Pad, and subtracting the Amplifier
Gain from the measured reading. The sample calculation is as follows :
FS = RA + AF + CF + AT - AG
where FS = Field Strength
RA = Receiver Amplitude
AF = Antenna Factor
CF = Cable Factor
AT = Antenna Pad
AG = Amplifier Gain
Assume a receiver reading of 78.2 dBμV is obtained. The antenna Factor of 14.0 dB, Cable Factor of 4.5 dB and Antenna
Pad of 6.0 dB is added. The Amplifier Gain of 28.3 dB is subtracted, giving a field strength of 74.4 dBμV/m.
FS = 78.2 + 14.0 + 4.5 + 6.0 – 28.3 = 74.4 dBμV/m
