2. SYSTEM TEST CONFIGURATION
The tests documented in this report were performed in accordance with ANSI C63.4-2003 and
FCC CFR 47 Part 15 Subpart C.

2.1 EUT Configuration

The EUT configuration for testing is installed on RF field strength measurement to meet the
Commissions requirement and operating in a manner that intends to maximize its emission
characteristics in a continuous normal application.

2.2 EUT Exercise

The calibrated antennas used to sample the radiated field strength are mounted on a non-
conductive, motorized antenna mast 3 or 10 meters from the leading edge of the turntable.

2.3 General Test Procedures

Conducted Emissions The EUT is placed on the turntable, which is 0.8 m above ground plane.
According to the requirements in Section 7.1 of ANSI C63.4-2003.Conducted emissions from the
EUT measured in the frequency range between 0.15 MHz and 30MHz using CISPR Quasi-Peak
detector mode.

Radiated Emissions The EUT is a placed on as turntable, which is 0.8 m above ground plane.
The turntable shall rotate 360 degrees to determine the position of maximum emission level. EUT
is set 3m away from the receiving antenna, which varied from 1m to 4m to find out the highest
emission. And also, each emission was to be maximized by changing the polarization of receiving
antenna both horizontal and vertical. In order to find out the maximum emissions, exploratory
radiated emission measurements were made according to the requirements in Section 13.1.4.1 of
ANSI C63.4-2003.

Report No.: BCT07AR-032E Page 7 of 16

5.4 Test Procedure

Maximizing procedure was performed on the highest emissions to ensure that the EUT complied
with all installation combinations.

1). Configure the EUT according to ANSI C63.4:2003.

2). The EUT was placed on the top of the turntable 0.8 meter above ground.

3). The receiving antenna was placed 3 meters far away from the turntable.

4). The turntable was rotated by 360 degrees to determine the position of the highest radiation.

5). For Spurious Emissions test, The height of the broadband receiving antenna was varied
between one meter and four meters above ground to find the maximum emission field strength
of both horizontal and vertical polarization. For each suspected emission, the antenna tower
was scanned (from 1 M to 4 M) and then the turntable was rotated (from 0 degree to 360
degrees) to find the maximum reading.

6). For Field Strength of Fundamental Emissions test, Positioned the loop antenna with its plane
vertical at the specified distance of 3 meters between its center and the EUT. The center of
the loop antenna is set with 1m above the grounded plane. Then rotated about its vertical axis
for finding out the maximum emission level of the EUT.

Remark: Duty Cycle Correction

Each function key sends a different series of characters, but each packet period (15.65msec)
never exceeds a series of 4 long (1.2msec) and 10 short (0.35msec) pulses. Assuming any
combination of short and long pulses may be obtained due to encoding the worst case
transmit duty cycle would be considered 4x1.2msec+10x0.35msec per 15.65msec =53%
duty cycle. Figure A through C show the characteristics of the pulse train for one of these
functions.

Remark:
--- Means that The emission level of the rest measuring harmonic up to 5GHz are so low below
applicable limit in operation mode, so the result were not recorded.

Remark: The ‘Transd. ‘ in the above table is the Corrected Amplitude calculated by adding the
Antenna Factor and Cable Factor, and subtracting the Amplifier Gain from the
Amplitude reading. The basic equation is as follows:

Transd. = Indicated Reading + Antenna Factor + Cable Factor - Amplifier Gain
