3.5 Operating Condition of EUT
3.5.1 Setup the EUT and peripherals as shown in Sec. 3.2.

3.5.2 Turn on the power of all equipments and the EUT.

3.5.3 The DTV SG provide a 82dBuV digital signal to the EUT during the
test.

3.5.4 Set the EUT on the test mode and then test.

3.6 Test Procedures
The EUT and peripherals were connected to the power mains through an
Artificial Mains Network (AMN). This provided a 50 ohm coupling impedance
for the measuring equipment.

Both sides of AC line (Line & Neutral) were checked for maximum conducted
interference. In order to find the maximum emission, the relative positions of
equipment and all of the interface cables were changed or manipulated
according to ANSI C63.4:2003 during conducted emission test.

The bandwidth of R&S Test Receiver ESCI was set at 9 kHz.

The frequency range from 150 kHz to 30 MHz was checked.

The test modes were done on conducted disturbance test and all the test results
are listed in Sec. 3.7.

3.7 Test Results
< PASS >

The frequency and amplitude of the highest conducted emission relative to the
limit is reported. All emissions not reported below are too low against the
prescribed limits.

Test Mode Page
AV Output Mode P11
TV Output Mode P12

NOTE 1 – Factor = Cable Loss + AMN Factor.
NOTE 2 – Emission Level = Meter Reading + Factor.
NOTE 3 – “QP” means “Quasi-Peak” values, “AV” means “Average” values.
NOTE 4 – The worst case is for AV Output Mode. The worst emission is
detected at 0.183 MHz (QP Value) with corrected signal level of
54.69 dB (μV) (limit is 64.35 dB (μV)), when the Line of the EUT
is connected to AMN.

88 ~ 216 3 150 43.5
216 ~ 960 3 200 46.0
Above 960 3 500 54.0
NOTE 1 - Emission Level dB (μV/m) = 20 log Emission Level (μV/m)
NOTE 2 - The tighter limit applies at the band edges.
NOTE 3 - Distance refers to the distance in meters between the measuring
instrument antenna and the closed point of any part of the device or
system.
NOTE 4 - The limits shown are based on Quasi-peak value detector below or
equal to 1GHz and Average value detector above 1GHz.
NOTE 5 - Above 1 GHz, the limit on peak emission is 20 dB above the maximum
permitted average emission limit applicable to the EUT.

4.4 Test Configuration
The configuration of the EUT and peripherals are same as those used in
conducted emission test.

Please refer to Sec.3.4.

4.5 Operating Condition of EUT
Same as conducted emission test which is listed in Sec.3.5, except for the test
setup replaced by Sec.4.2.

4.6 Test Procedures
The EUT and peripherals were placed on a FRP turntable that is 0.8 meter
above ground. The FRP turntable rotated 360 degrees to determine the position
of the maximum emission level. The EUT was set 3 meters away from the
receiving antenna, which was mounted on an antenna tower. Broadband
antenna (Calibrated Bilog Antenna) or Horn antenna was used as receiving
antenna. The antenna moved up and down between 1 meter and 4 meters to find
out the maximum emission level. Both horizontal and vertical polarizations of
the antenna were set on measurement. In order to find the maximum emission,
all of the interference cables were manipulated according to ANSI C63.4:2003
requirements during radiated emission test.

The I.F. bandwidth of Test Receiver R&S ESCI was set at 120 kHz below
1GHz and The Spectrum Agilent E7405A was set at 1MHz above 1GHz.

The frequency range from 30 MHz to 5000MHz was checked for all test
modes.

The test modes were done on radiated disturbance test and all the test results are
listed in Sec.4.7.

4.7 Test Results
<PASS>

The frequency and amplitude of the highest radiated emission relative the limit
is reported. All the emissions not reported below are too low against the FCC
limit.

Test Mode Page
AV Mode P17
TV Mode P18

NOTE 1 – Emission Level = Antenna Factor + Cable Loss + Meter
Reading. (< 1GHz)
NOTE 2 – Emission Level = Antenna Factor + Cable Loss – Preamp
Factor + Meter Reading. (> 1GHz)
NOTE 3 – All readings are Quasi-Peak values below or equal to 1GHz,
Peak values and Average values above 1GHz.
NOTE 4 – The emission levels that are 20dB below the official limit are
not reported.
NOTE 5 – 0° was the table front facing the antenna. Degree is calculated
from 0° clockwise facing the antenna.
NOTE 6 – The worst case is for AV Mode. The worst emission at
horizontal polarization was detected at 333.352MHz with
corrected signal level of 41.10 dB (μV/m) (limit is 46.00 dB
(μV/m)), when the antenna was 2.00 m height and the turntable
was at 223°. The worst emission at vertical polarization was
detected at 333.366 MHz with corrected signal level of 41.30
dB (μV/m) (limit is 46.00 dB (μV/m)), when the antenna was
1.00 m height and the turntable was at 147°.

(f) The spectrum was scanned from 30 MHz to more than 4.6 MHz below the
visual carrier frequency, and from more than 7.4 MHz above the visual
carrier frequency to 1000 MHz, and the three highest emissions are
selected under the EUT condition produced the maximum signal level at
each frequency range.

(g) Then, the RF output terminal conducted spurious emission level is
measured under the EUT condition produced the maximum signal level.

7.2 Requirements
FCC Rule Part 15,§15.115 (d)

A TV interface device, including a cable system terminal device, shall
incorporate circuitry to automatically prevent emanations from the device from
exceeding the technical specifications in this part. These circuits shall
be adequate to accomplish their functions when the TV interface device is
presented, if applicable, with video input signal levels in the range of one to five
volts. For devices that contain provisions for an external signal source but do not
contain provisions for the input of an external baseband signal, e.g., some cable
system terminal devices, compliance with the provisions of this paragraph shall
be demonstrated with a radio frequency input signal of 0 to 25 dBmV.
