The test and application are submitted for a Periodic Intentional Radiator under Part 15.231 of the FCC Rules and Regulations. The Equipment Under Test was the Key Fob Transmitter. All measurements herein were performed according to the 1992 version of ANSI C63.4. The measurement equipment conforms to ANSI C63.2 Specifications for Electromagnetic Noise and field Strength Instrumentation. Calibration checks are made periodically to verify proper performance of the measuring instrumentation. All measurements are performed at Washington Laboratories, Ltd. test center in Gaithersburg, MD. Site description and site attenuation data have been placed on file with the FCC's Sampling and Measurements Branch at the FCC laboratory in Columbia, MD. Washington Laboratories, Ltd. has been accepted by the FCC and approved by NIST NVLAP (NVLAP Lab Code: 200066-0) as an independent FCC test laboratory. All results reported herein relate only to the equipment tested. The measurement uncertainty of the data contained herein is ± 2.3 dB. Refer to Appendix A for Statement of Measurement Uncertainty. This report shall not be used to claim product endorsement by NVLAP or any agency of the US Government. 1.1Summary The Ness Security Systems Key Fob Transmitter complies with the limits for a Periodic Intentional Radiator under Part 15.231 of the FCC Rules and Regulations. 2.0Description of Equipment Under Test (EUT) The Ness Security Systems Key Fob Transmitter (EUT) is part of a home security alarm system and used to arm and disarm a security alarm system. The low-power transmitter operates at 303.85 MHz. This unit is used in conjunction with the Ness Security Systems Security Guard 3, FCC ID: O2K-SG3-304 (concurrent application). The unit is powered via a 2016 Lithium battery. 2.1On-board Oscillators The Ness Security Systems Key Fob Transmitter contains a 4MHz oscillator and a 303.85 SAW oscillator. Ness Security Products FCC ID: O2K-MK304 WLL Project #: 5678X 2 3.0Test Configuration To complete the test configuration required by the FCC, the transmitter was tested in all three orthogonal planes. All testing was performed with a fresh battery installed in the unit. 3.1Testing Algorithm The transmitter was modified, for testing purposes only, to continuously transmit a modulated carrier wave. The system was tested in all three orthogonal planes. Worst case emissions are recorded in the data tables. 3.2Radiated Emissions Testing The EUT was placed on an 80 cm high 1 x 1.5 meters non-conductive motorized turntable for radiated testing on a 3 meter open field test site. The emissions from the EUT w ere measured continuously at every azimuth by rotating the turntable. Biconilog and horn broadband antennas w ere mounted on an antenna mast to determine the height of maximum emissions. The height of the antenna was varied between 1 and 4 meters. The peripherals were placed on the table in accordance with ANSI C63.4-1992. Both the horizontal and vertical field components were measured. The output from the antenna was connected, via a preamplifier, to the input of the spectrum analyzer. The detector function was set to peak. For emissions below 1 GHz, the measurement bandwidth on the spectrum analyzer system was set to at least 120 kHz, with all post-detector filtering no less than 10 times the measurement bandwidth. For emissions above 1 GHz, the measurement bandwidth on the spectrum analyzer system was set to at least 1 MHz, with all post-detector filtering no less than 10 times the measurement bandwidth. 3.2.1Radiated Data Reduction and Reporting To convert the raw spectrum analyzer radiated data into a form that can be compared with the FCC limits, it is necessary to account for various calibration factors that are supplied with the anten…
