Full shielding is provided (ii) The modular transmitter must have buffered modulation/data inputs (if such inputs are provided. All modulation and data inputs are buffered by circuitry on the transmitter chip. (iii) The modular transmitter must have its own power supply regulation. Power supply regulation is provided by circuitry on the transmitter module. Input voltage range is 3.3VDC to 16VDC (iv) The modular transmitter must comply with the antenna and transmission system requirements of §§ 15.203, 15.204(b) and 15.204(c). Module has PC board antenna, or alternate external antenna utilizes special micro coaxial connector (v) The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with Part 15 parameters. Testing was performed with the module extended via cable outside of the host device. (vi) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. If the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. A sample of the host label is provided as an exhibit, showing the FCC identifier of the module. (vii) The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. The module complies fully with the operating requirements of Part 15 section 15.247 as demonstrated in the test report exhibit.

The remaining test sections are the verbatim text from the actual data sheets used during the investigation. These test sections include the test name, the specified test method, a list of the actual test equipment used, documentation photos, results and raw data. No additions, deviations, or exclusions have been made from the standard(s) unless specifically noted. Based on the results of our investigation, we have concluded the product tested complied with the requirements of the standard(s) indicated. The results obtained in this test report pertain only to the item(s) tested. The INTERTEK-Lexington is located at 731 Enterprise Drive, Lexington Kentucky, 40510. The radiated emission test site is a 10-meter semi-anechoic chamber. The chamber meets the characteristics of CISPR 16-1 and ANSI C63.4. For measurements, a remotely controlled flush-mount metal-top turntable is used to rotate the EUT a full 360 degrees. A remote controlled non-conductive antenna mast is used to scan the antenna height from one to four meters. The test site is listed with the FCC under registration number 485103. The test site is listed with Industry Canada under site number IC 2042M-1. 2 Test Summary Page Test full name FCC Reference IC Reference Result 6 Peak Conducted Power § 15.247(b)(3)(4) RSS-247 (5.4)(4) Pass 9 Occupied Bandwidth § 15.247(a)(2) RSS-247 (5.2)(1) RSS-GEN (4.6.1) Pass 14 Conducted Spurious Emissions § 15.247(d) RSS-247 (5.5) Pass 16 Power Spectral Density § 15.247(e) RSS-247 (5.2)(2) Pass 19 Radiated Spurious Emissions (Transmitter) § 15.247(d), § 15.209, and § 15.205 RSS-247 (5.5) Pass 29 AC Powerline Conducted Emissions § 15.107, § 15.207 RSS-Gen (7.2.4) Pass 34 Antenna Requirement per FCC Part 15.203 § 15.203 RSS-Gen (7.1.2) Pass Intertek Report Number: 102216394LEX-001 Issued: 9/2/2015 EMC Report for Opex Corporation on the 2.4GHz Spread Spectrum Transceiver Page 4 of 36 3 Description of Equipment Under Test Equipment Under Test Manufacturer Opex Corporation Model Number 2054710 Serial Number Test Sample 1 Receive Date 8/1/2015 Test Start Date 8/1/2015 Test End Date 8/12/2015 Device Received Condition Good Test Sample Type Production Frequency Band 2405MHz – 2480MHz Mode(s) of Operation Zigbee Modulation Type OFDM Duty Cycle 100% Transmission Control Test commands were…
