Engineering Test Report No. 36460-01 Measurement of RF Emissions from a Model 1A5510CLT1D Transmitter 1.0 INTRODUCTION: 1.1 Description of Test Item - This document represents the results of the series of radio interference measurements performed on a Transmitter, Model No.1A5510CLT1D Transmitter, no serial number was assigned, (hereinafter referred to as the test item). The test item was designed to transmit at approximately 315.0MHz using an internal antenna. The test item was manufactured and submitted for testing by Chamberlain Manufacturing located in Elmhurst, IL. 1.2 Purpose - The test series was performed to determine if the test item meets the conducted and radiated RF emission requirements of the FCC "Code of Federal Regulations" Title 47, Part 15, Subpart C, Sections 15.231 for Intentional Radiators. Testing was performed in accordance with ANSI C63.4- 2004. 1.3 Deviations, Additions and Exclusions - There were no deviations, additions to, or exclusions from the test specification during this test series. 1.4 Applicable Documents - The following documents of the exact issue designated form part of this document to the extent specified herein: - Federal Communications Commission "Code of Federal Regulations", Title 47, Part 15, Subpart C, dated 1 October 2005 - ANSI C63.4-2004, "American National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz" 1.5 Subcontractor Identification - This series of tests was performed by Elite Electronic Engineering Incorporated of Downers Grove, Illinois. The laboratory is accredited by the National Institute of Standards and Technology (NIST) under the National Voluntary Laboratory Accreditation Program (NVLAP). NVLAP Lab Code: 100278-0. 1.6 Laboratory Conditions The temperature at the time of the test was 21.3oC and the relative humidity was 22%. 2.0 TEST ITEM SET-UP AND OPERATION: The test item is a Transmitter, Part No.1A5510CLT1D. A block diagram of the test item set-up is shown as Figure 1. 2.1 Power Input - The test item obtained 9VDC from a 9VDC battery. Page 4 of 17

Engineering Test Report No. 36460-01 2.2 Grounding - Since the test item was powered with 9VDC from a 9VDC internal battery, it was ungrounded during the tests. 2.3 Peripheral Equipment - The test item has no peripheral equipment. 2.4 Interconnect Cables - The test item has no interconnect cables or ports. 2.5 Operational Mode - For all tests the test item and all peripheral equipment were placed on an 80cm high non-conductive stand. The transmit button of the test item was held down during testing thereby setting the unit to transmit continuously. The transmitting mechanism automatically deactivated when the transmit button was released. The battery voltage was periodically checked to ensure proper operation. The test was performed with the test item transmitting at 315.0MHz. 2.6 Test Item Modifications - No modifications were required for compliance to the FCC Part 15C requirements. 3.0 TEST EQUIPMENT: 3.1 Test Equipment List - A list of the test equipment used can be found on Table I. All equipment was calibrated per the instruction manuals supplied by the manufacturer. 3.2 Calibration Traceability - Test equipment is maintained and calibrated on a regular basis. All calibrations are traceable to the National Institute of Standards and Technology (NIST). 3.3 Measurement Uncertainty - All measurements are an estimate of their true value. The measurement uncertainty characterizes, with a specified confidence level, the spread of values which may be possible for a given measurement system. 4.0 REQUIREMENTS, PROCEDURES AND RESULTS: 4.1 Powerline Conducted Emissions - 4.1.1 Requirements –Since the test item was powered by internal batteries, no conducted emissions tests were performed. 4.2 Duty Cycle Factor Measurements - 4.2.1 Procedures - The duty cycle factor is used to convert peak detected readings to average readings. This factor is computed from the time domain trace of the pulse modulation signal. With the transmitter set up to transmit for maximum pulse density, the time domain trace is displayed on the spectrum analyzer. This trace is obtained by tuning center frequency to the transmitter frequency and then setting a zero span width with 10msec/div. The amplitude settings are adjusted so that the on/off transitions clear the 4th division from the bottom of the display. The markers are set at the beginning and end of a word period. If the word period exceeds 100 msec the word period is set to Page 5 of 17

Engineering Test Report No. 36460-01 100 msec. The on-time and off-time are then measured. The on-time is total time signal level exceeds the 4th division. Off-time is time under for the word period. The duty cycle is then computed as the (On- time/ word period) where the word period = (On-time + Off-time). 4.2.2 Results - A representative plot of the duty cycle is shown on data page 12. Since the transmitter uses a rolling code, the duty cycle correction factor used was calculated based on the average case. The following average case information was supplied by Chamberlain Manufacturing: An average ON time is used because of the ever changing rolling code. For 100 msec period: 1msec average sync pulse (50% of the time the sync pulse is 0.5msec and 50% of the time the sync pulse is 1.5msec) 20 digits for a total time of 40 msec, but only half of them are ON (oscillator running) for an average of 20 msec. 59msec average blanktime The total is 100msec. 20 log 21/100 = -13.5 With the test item transmitting at 315.0MHz, the average case duty cycle correction factor would be -13.5dB. 4.3 Radiated Measurements - 4.3.1 Requirements - The test item must comply with the requirements of FCC "Code of Federal Regulations Title 47", Part 15, Subpart C, Section 15.205 et seq. Paragraph 15.231(b) has the following radiated emission limits: Fundamental Field Strength Frequency Field Intensity Harmonics and MHz _ uV/m @ 3 meters Spurious @ 3 meters 260 to 470 3,750 to 12,500* 375 to 1,250* * - Linear Interpolation For 315.0MHz, the limit at the fundamental is 6041.7uV/m @ 3m and the limit on the harmonics is 604.2uV/m @ 3m. In addition, emissions appearing in the Restricted Bands of Operation listed in paragraph 15.205(a) shall not exceed the general requirements shown in paragraph 15.209. Page 6 of 17

Engineering Test Report No. 36460-01 4.3.2 Procedures - Open field measurements were performed in a 32ft. x 20ft. x 14ft. high shielded enclosure. The shielded enclosure prevents emissions from other sources, such as radio and TV stations from interfering with the measurements. All powerlines and signal lines entering the enclosure pass through filters on the enclosure wall. The powerline filters prevent extraneous signals from entering the enclosure on these leads. A preliminary radiated emissions test was performed to determine the emission characteristics of the test item. For the preliminary test, a broadband measuring antenna was positioned at a 3 meter distance from the test item. The entire frequency range from 30MHz to 5.0GHz was investigated using a peak detector function. The data was then processed by the computer to calculate equivalent field intensity. The final open field emission tests were then manually performed over the frequency range of 30MHz to 5.0GHz. Between 30MHz and 1000MHz, a bilog antenna was used as the pick-up device. A broadband double ridged waveguide antenna was used as the pick-up device for all frequencies above 1GHz. All significant broadband and narrowband signals were measured and recorded. The peak detected levels were converted to average levels using a duty cycle factor which was computed from the pulse train. To ensure that maximum or worst case, emission levels were measured, the following steps were taken: (1) The test item was rotated so that all of its sides were exposed to the receiving antenna. (2) Since the measuring antenna is linearly polarized, both horizontal and vertical field components were measured. (3) The measuring antenna was raised and lowered from 1 to 4 meters for each antenna polarization to maximize the readings. (4) For hand-held or body-worn devices, the test item was rotated through three orthogonal axes to determine which orientation produces the highest emission relative to the limit. 4.3.3 Results - The preliminary plots, with the test item transmitting at 315.0MHz, are presented on data pages 13 and 14. The plots are presented for a reference only, and are not used to determine compliance. The final open area radiated levels, with the test item transmitting at 315.0MHz, are presented on data page 15. As can be seen from the data, all emissions measured from the test item were within the Page 7 of 17

Engineering Test Report No. 36460-01 specification limits. The emissions level closet to the limit (worst case) occurred at 1575MHz. The emissions level at this frequency was 4.6dB within the limit. See data page 15 for details. Photographs of the test configuration which yielded the highest fundamental radiated emission levels are shown on Figure 2. 4.4 Occupied Bandwidth Measurements - 4.4.1 Requirement - In accordance with paragraph 15.231(c), all emissions within 20dB of the peak amplitude level of the center frequency are required to be within a band less than 0.25% of the center frequency wide. 4.4.2 Procedures - The test item was placed on an 80cm high non-conductive stand. The unit was set to transmit continuously. With an antenna positioned nearby, occupied bandwidth emissions were displayed on the spectrum analyzer. The resolution bandwidth was set to 30 kHz and span was set to 2 MHz. The frequency spectrum near the fundamental was plotted. 4.4.3 Results - The plot of the emissions near the fundamental frequency are presented on data page 16. As can be seen from this data page, the transmitter met the occupied bandwidth requirements. In addition, the 99% emission bandwidth measured 240 kHz when using the analyzer’s special function key with the measurement BW set to 30 kHz. 5.0 CONCLUSIONS: It was determined that the Chamberlain Manufacturing Transmitter, Part No. 1A5510CLT1D, no serial number assigned, did fully meet the radiated emission requirements of the FCC "Code of Federal Regulations" Title 47, Part 15, Subpart C, Section 15.205 et seq. for Intentional Radiators, when tested per ANSI C63.4-2004. 6.0 CERTIFICATION: Elite Electronic Engineering Incorporated certifies that the information contained in this report was obtained under conditions which meet or exceed those specified in the test specifications.
