NEUTRON EMC LAB. FCC ID: ELVMTBA 3. System Test Configuration 3-1. EUT Configuration The EUT configuration for testing is installed on RF field strength measurement to meet the Commissions requirement and operating in a manner which intends to maximize its emission characteristics in a continuous normal application. 3-2. EUT Exercise The EUT (Transmitter) was operated continuously in its normal operating mode for the pur- pose of the measurements. 3-3. Test Procedure 3-3-1. Conducted Emissions (Not applicable in this report) 3-3-2. Radiated Emissions The EUT is a placed on as turn table which is 1.0m above ground plane. The turn table 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 po- larization of receiving antenna both horizontal and vertical. In order to find out the max. emission, the relative positions of this hand-held transmitter(EUT) was rotated through three orthogonal axes according to the requirements in Section 13.1.4.1 of ANSI C63.4-1992. Radiated emissions from the EUT measured in the frequency range between 30 MHz and 1000MHz were made with a Spectrum Analyzer, HP Model 8568B, us- ing CISPR Quasi-Peak detector mode and appropriate broadband linearly polarized antenna or Peak detector mode and a duty cycle correction factor corrected for the average value of the emission. Radiated emissions measurement for frequency above 1000MHz were made with a Test Receiver, R&S model ESMI, plus a Pre-amplifier R&S model ESMI-Z7 , and a Horn Antenna, EMCO model 3115 to measure its Peak Detector Mode level and correct it with the duty cycle correction factor. 6/22

(6) Radiated emissions measured in frequency range from 30 MHz to 1000 MHz were made with an instrument using Peak detector mode and a duty cycle correct factor cor- rected for the average value of the emission shown in AV column。Example of calcula- tion for actual field strength express in average value is exhibited in paragraph (B) of 6-2. Field Strength Calculation in this test report. (7) Radiated emissions measured in frequency above 1000MHz were made with a Test Receiver, R&S model ESMI, plus a Pre-amplifier R&S model ESMI-Z7, and a Horn An- tenna, EMCO model 3115 .

Field Strength Calculation The field strength is calculated by adding the Antenna Factor and Cable Factor and subtracting the Amplifier Gain and Duty Cycle Correction Factor(if any) from the measured reading. The basic equa- tion with a sample calculation is as follows: FS = RA + AF + CL - AG - DFC Where FS = Field Strength RA = Receiver Amplitude AF = Antenna Factor (1) CL = Cable Attenuation Factor (Cable Loss) (1) AG = Amplifier Gain (1) DFC = Duty Cycle Correction Factor (2) Remark : (1) The Correction Factor = AF + CL - AG, as shown in the data tables' Correction Factor col- umn. (2) DFC is available only for radiated emissions measurement(s) in frequency above 1000MHz. (A). Example of Calculation for frequency over 1000MHz: Assume a Receiver Reading of 23.7 dBuV is obtained with an Antenna Factor of 17.0 dB and a Cable Factor of 25.0 dB and Pre-Amplifier Gain of 20 dB. Then: 1. The Correction Factor will be calculated by Correction Factor = AF + CL - AG = 13.3 + 10.0 - 15.0= 8.3 (dB) as shown in the data tables' Ant./CL CF column. 2. The Field Strength will be calculated by FS = RA + Correction Factor = 23.7+8.3 = 32 (dBuV/m). (B). Example of Calculation for frequency range between 30MHz and 1GHz: Assume a Receiver Reading of 73.7 dBuV is obtained with an Antenna Factor of 7.2 dB and a Cable Factor of 1.1 dB and Duty Cycle Correction Factor Calculated as - 7.6dB. Then: 1. The Correction Factor will be calculated by Correction Factor = AF + CL = 7.2 + 1.1 = 8.3 (dB) as shown in the data tables' Ant./CL CF column. 2. The Field Strength will be calculated by FS = RA + Ant./CL CF+ Duty Cycle CF = 31.3 + 8.3 −7.6 = 32 (dBuV/m). FS is the value shown in the data tables' Actual FS column and RA is the value shown in the data tables' Reading column. The 32 dBuV/m value was mathematically converted to its corre spooning level in uV/m as: Log-1 【(32.0dBuV/m)/20 】＝ 39.8 (uV/m) 16/22

Duty Cycle of a Pulse Train T(P) The periodic of a pulse train measured as 100 ms : ( refer to Attachment A.) In accordance with 15.35(C) of FCC, the max allowable pulse train is 0.1 s T(P) = 100ms 2. Total Duration of EUT at active state(high level state) The max T(on) within 0.1 s = 20 x 1.155 + 17 x 0.3666 = 29.3322ms 3. The duty cycle correction factor then calculated as the follows ： Factor = 20 ㏒[ T(on) / T(P) ] = 20 ㏒(29.3322/100) = -10.65 (dB) 4. Detail informations refer to Attachment A. 17/22

Supplementary Information for Section 15.231(C) Requirements 7.1 Bandwidth requirement The center frequency fc is 433.92Mhz (point 3), according to the Rules, section 15.231(C), the Bandwidth of Center Frequency at-20dB should be calculated as following: 433.92 X 0.0025 = 1.0848(MHz) So, the Upper /Lower frequencies should be specified as : f(U) = fc + ∆ f/2 = 433.92 + 0.5424 = 434.46(MHz) (point 5) f(L) = fc - ∆ f/2 = 433.92 – 0.5424 = 433.377 (MHz) (point 1) The measured frequencies at -20dB Bandwidth of Fundamental are f (point 4) and f (point 2) as shown in the spectrum graphic above. Either f (point 4) or f(point 2) located within the band of frequency between f(L) =433.377 MHz and f(U) = 434.46 MHz. So, it is complacence with the requirements. 18/22
