IVR IA Report No.: 160928001301 3. DESCRIPTION OF TEST 3.1. Evaluation Procedure The measurement procedures described in the American National Standard for Methods of Measurement of Radio—Noise Emission from Low—Voltage Electrical Equipment in the Range of 9kHz to 18GHz (ANSI C€63.4—2014) was used in the measurement of the Ultra—elegant Gigabit IP Phone FCC ID: T2C—T48S. DBViatiOn fFOM ME@SUF@MENt DFOGEUUT@..................cll ces e en emmemmeenmnemernmnnemernence ... NONn€ 3.2. AC Line Conducted Emissions The line—conducted facility is located inside an 8x4‘x4‘ shielded enclosure. A 1m x 2m wooden table 80cm high is placed 40¢m away from the vertical wall and 8Ocm away from the sidewall of the shielded room. Two 10kHz—30MHz, 500/50uH Line—Impedance Stabilization Networks (LISNs) are bonded to the shielded room floor. Power to the LISNsis filtered by external high—current high—insertion loss power line filters. These filters attenuate ambient signal noise from entering the measurement lines. These filters are also bonded to the shielded enclosure. The EUT is powered from one LISN and the support equipment is powered from the second LISN. If the EUT is a DC—powered device, power will be derived from the source power supply it normally will be powered from and this supply line(s) will be connected to the second LISN. All interconnecting cables more than 1 meter were shortened to a 1 meter length by non—inductive bundling (serpentine fashion) and draped over the back edge of the test table. All cables were at least 40cm above the horizontalreference ground—plane. Power cables for support equipment were routed down to the second LISN while ensuring that that cables were not draped over the second LISN. Sufficient time for the EUT, support equipment, and test equipment was allowed in order for them to warm up to their normal operating condition. The RF output of the LISN was connected to the receiver and exploratory measurements were made to determine the frequencies producing the maximum emission from the EUT. The receiver was scanned from 150 kHz to 30 MHz. The detector function was set to peak mode for exploratory measurements while the bandwidth of the analyzer was set to 9 kHz. The EUT, support equipment, and interconnecting cables were arranged and manipulated to maximize each emission. Each emission was also maximized by varying: power lines, the mode of operation or resolution, clock or data exchange speed, serolling H pattern to the EUT and/or support equipment whichever determined the worst—case emission. Once the worst case emissions have been identified, the one EUT cable configuration/arrangement and mode of operation that produced these emissions are used for final measurements on the same test site. Line conducted emissions test results are shown in Section 6.2. FCC ID: T2C—T488 Page Number: 9 of 27

IVR IA Report No.: 160928001301 3.3. Radiated Emissions The radiated test facilities consisted of an indoor 3 meter semi—anechoic chamber used for final measurements and exploratory measurements, when necessary. The measurement area is contained within the semi—anechoic chamber which is shielded from any ambient interference. For measurements above 1GHz absorbers are arranged on the floor between the turn table and the antenna mast in such a way so as to maximize the reduction of reflections. For measurements below 1GHz, the absorbers are removed. An MF Model 210SS turntable is used for radiated measurement. It is a continuously rotatable, remote controlled, metallic turntable and 2 meters (6.56 ft.) in diameter. The turn table is flush with the raised floor of the chamber in order to maintain its function as a ground plane. An 80em high PVC support structure is placed on top of the turntable. For all measurements, the spectrum was scanned through all EUT azimuths and from 1 to 4 meter receive antenna height using a broadband antenna from 30 MHz up to the upper frequency shown in 15.33(b)(1) depending on the highest frequency generated or used in the device or on which the device operates or tunes. For frequencies above 1GHz, linearly polarized double ridge horn antennas were used. For frequencies below 30 MHz, a calibrated loop antenna was used. When exploratory measurements were necessary, they were performed at 1 meter test distance inside the semi—anechoic chamber using broadband antennas, broadband amplifiers, and spectrum analyzers to determine the frequencies and modes producing the maximum emissions. Sufficient time for the EUT, support equipment, and test equipment was allowed in order for them to warm up to their normal operating condition. The test set—up was placed on top of the 0.8 meter high, 1 x 1.5 meter table. The EUT, support equipment, and interconnecting cables were arranged and manipulated to maximize each emission. Appropriate precaution was taken to ensure that all emissions from the EUT were maximized and investigated. The system configuration, mode of operation, if applicable, turntable azimuth, and receive antenna height was noted for each frequency found. Final measurements were made in the semi—anechoic chamber using calibrated, linearly polarized broadband and horn antennas. The test setup was configured to the setup that produced the worst case emissions. The spectrum analyzer was set to investigate all frequencies required for testing to compare the highest radiated disturbances with respect to the specified limits. The turntable containing the EUT was rotated through 360 degrees and the height of the receive antenna was varied 1 to 4 meters and stopped at the azimuth and height producing the maximum emission. Each emission was maximized by changing the orientation of the EUT through three orthogonal planes and changing the polarity of the receive antenna, whichever produced the worst—case emissions. According to 3B beam—width of horn antenna, the horn antenna should be always directed to the EUT when rising height. FCC ID: T2C—T488 Page Number: 10 of 27
