This is an application for certification of a transceiver for the onn. Full HD Streaming Device Google TV which has BT BLE function. Previous reports cover classic Bluetooth (230427001SZN-001), 2.4GHz WIFI (230427001SZN-003), and 5GHz WIFI (230427001SZN-004).

2.3 Test Methodology

Measurements were performed according to ANSI C63.10 (2013) and KDB 558074 D01 v05r02. Radiated emission measurements were conducted in a semi-anechoic chamber, and conducted emission measurements were performed in a shield room. Preliminary scans determined worst-case modes. All radiated tests were performed at an antenna-to-EUT distance of 3 meters, unless otherwise specified.

2.4 Test Facility

The Semi-anechoic chamber and shielded room are located at Intertek Testing Services Shenzhen Ltd. Longhua Branch, 101, 201, Building B, No. 308 Wuhe Avenue, Zhangkengjing Community, GuanHu Subdistrict, LongHua District, Shenzhen, P.R. China. This facility is accredited and has been filed with the FCC under File Number: CN1188.

3.0 System Test Configuration

3.1 Justification

For emissions testing, the EUT was set up to transmit continuously to simplify the measurement methodology. Power supply voltages were carefully monitored. Cables were manipulated to produce worst-case emissions. The EUT was powered by DC 5V from an adapter.

For maximizing emissions, the EUT was rotated 360 degrees. The EUT was placed on a turntable 0.8m above the ground for frequencies up to 1GHz and 1.5m above for frequencies above 1GHz. Antenna height and polarization were varied to find the maximum signal level, with antenna height ranging from 1 to 4 meters. Radiated emissions were measured at three meters, or at a closer distance if signal levels were too low. Pre-amplifiers were used as necessary.

All readings were extrapolated to the equivalent three-meter reading using inverse scaling. Analyzer resolution was 100 kHz or greater below 1000 MHz, and 1 MHz or greater above 1000 MHz. Spurious emissions more than 20 dB below the permissible value were not reported. The rear of the unit was flushed with the rear of the table.

Radiated emission measurements covered frequencies from 9 kHz up to the tenth harmonic of the highest fundamental frequency, or 40 GHz, whichever is lower.

3.2 EUT Exercising Software

The EUT exercise program, provided by the client, was used to exercise various system components similarly to typical use, ensuring worst-case configurations were tested. Channel and power controlling software was used to set the operating channel and output power level, which is fixed in the end product's firmware.

4.0 Measurement Results

4.1 Field Strength Calculation

Field strength is calculated by adding the spectrum analyzer reading to factors for preamplifiers, antennas, cables, pulse desensitization, and average factors (if applicable). The formula used is:

FS = RA + AF + CF - AG + PD

Where:

• FS = Field Strength in dBuV/m
• RA = Receiver Amplitude (including preamplifier) in dBuV
• CF = Cable Attenuation Factor in dB
• AF = Antenna Factor in dB
• AG = Amplifier Gain in dB
• PD = Pulse Desensitization in dB

The radiated emission tables may reflect preamplifier gain. An example calculation where the reading does not reflect preamplifier gain is provided:

Example: A receiver reading of 62.0 dBuV, antenna factor of 7.4 dB, and cable factor of 1.6 dB are added. Amplifier gain of 29 dB is subtracted. Pulse desensitization is 0 dB. The net field strength is 42 dBuV/m.

FS = 62.0 + 7.4 + 1.6 - 29.0 + 0 = 42 dBuV/m

This value is converted to µV/m: Level in mV/m = Common Antilogarithm [(42 dBuV/m)/20] = 125.9 µV/m.

4.2 Radiated Spurious Emission

The worst-case radiated spurious emission at 2390.000MHz passed with a margin of 6.1dB.

For electronic filing, worst-case radiated emission configuration photographs are saved in 'radiated photos.pdf'. Simultaneous transmission was considered during testing, and only the worst-case data is recorded.

Radiated Emissions (below 1GHz)

Horizontal Polarity

The graph shows measured electric field strength (QP) for FCC Part 15 Class B across frequencies from 30 MHz to 1 GHz. Specific data points are listed in the table below.

Remark:
1. Corr. = Antenna Factor (dB/m) + Cable Loss (dB)
2. Quasi Peak (dBμV/m) = Corr. (dB/m) + Read Level (dBμV)
3. Margin (dB) = Limit Line (dBμV/m) – Level (dBμV/m)

Vertical Polarity

The graph shows measured electric field strength (QP) for FCC Part 15 Class B across frequencies from 30 MHz to 1 GHz. Specific data points are listed in the table below.

Remark:
1. Corr. = Antenna Factor (dB/m) + Cable Loss (dB)
2. Quasi Peak (dBμV/m) = Corr. (dB/m) + Read Level (dBμV)
3. Margin (dB) = Limit Line (dBμV/m) – Level (dBμV/m)

Horizontal Polarity (Transmitting Channel 0)

Horizontal Polarity (Transmitting Channel 19)

Note: The following table shows radiated emissions for Horizontal Polarization, Transmitting Channel 19.

Vertical Polarity (Transmitting Channel 19)

Vertical Polarity (Transmitting Channel 39)

Note: The following table shows radiated emissions for Vertical Polarity, Transmitting Channel 39.

NOTES:
1. Peak detector is used, RBW=1MHz/VBW=3MHz for peak value and RBW=1MHz / VBW=10Hz for average value.
2. All measurements were made at 3 meters. Radiated emissions not detected at the 3-meter distance were measured at 0.3-meter and an inverse proportional extrapolation was performed to compare the signal level to the 3-meter limit. No other radiated emissions than those reported were detected at a test distance of 0.3-meter.
3. Negative value in the margin column shows emission below limit.
4. Horn antenna used for the emission over 1000MHz.
* Emission within the restricted band meets the requirement of section 15.205. The corresponding limit as per 15.209 is based on Quasi peak limit for frequencies below 1000 MHz and average limit for frequencies over 1000 MHz. The radio frequency emissions above 1GHz also meet corresponding 20dB permitted peak limit with a peak detector function.

10.0 Discussion of Pulse Desensitization

The determination of pulse desensitivity was made in accordance with Hewlett Packard Application Note 150-2, Spectrum Analysis ... Pulsed RF. Pulse desensitivity is not applicable for this device since the transmitter transmits the RF signal continuously.
