2.2 Description of EUT
The C4-CORE5 is a home entertainment controller, used to control home entertainment and home automation which features five independent audio outputs ­ three digital coaxial, three unbalanced stereo analog, one HDMI Out, wireless Zigbee and Z-wave communications, IR, serial, contacts and relays, and IP control. It also features a USB 3.0 connection for connection to external hard drives and a gigabit LAN port. It is powered via the AC mains and an internal 100-240Vac, 50/60Hz power supply.
The highest internal clocks or internal clock frequency on the EUT is the 2.4 GHz Zigbee wireless clock, and the internal system clock of 1.6 GHz.
This report covers the circuitry of the device subject to FCC Part 15, Subpart C. The circuitry of the device subject to FCC Part 15 Subpart B was found to be compliant and is covered under a separate Compliance Test Services test report.

5.5 §15.247(d) Spurious Emissions
5.5.1 Conducted Spurious Emissions
The frequency range from the lowest frequency generated or used in the device to the tenth harmonic of the highest fundamental frequency was investigated to measure any antenna-conducted emissions. The table show the measurement data from spurious emissions noted across the frequency range when transmitting at the lowest frequency, middle frequency and upper frequency. Shown below are plots with the EUT tuned to the upper and lower channels. These demonstrate compliance with the provisions of this section at the band edges. The emissions must be attenuated 30 dB below the highest power spectral density level measured within the authorized band as measured with a 100 kHz RBW. The highest power measured power spectral density was 2.3 dBm; therefore, the criteria is 2.3 ­ 30 = -27.7 dBm. Result Conducted spurious emissions were attenuated 30 dB or more below the fundamental; therefore, the EUT complies with the specification.

5.5.2 Radiated Spurious Emissions in the Restricted Bands of §15.205
The frequency range from the lowest frequency generated or used in the device to the tenth harmonic of the highest fundamental emissions was investigated to measure any radiated emissions in the restricted bands. The following tables show measurements of any emissions that fell into the restricted bands of §15.205. The tables show the worst-case emissions measured from the EUT. For frequencies above 18.0 GHz, a measurement distance of 1 meter was used. The noise floor was a minimum of 6 dB below the limits. The emissions in the restricted bans must meet the limits specified in §15.209. Tabular data for each of the spurious emissions is shown below for each of the units. Plots of the band edges are also shown.

Result All emissions in the restricted bands of §15.205 met the limits specified in §15.209; therefore, the EUT complies with the specification.

5.6 §15.247(e) Maximum Average Power Spectral Density

The maximum average power spectral density conducted from the intentional radiator of the antenna shall

not be greater than 8 dBm in any 3 kHz band during any time interval of continuous transmission. Results of this testing are summarized.
