L2MK9310Security Device Transmitter

APPLICANT: OMEGA RESEARCH AND DEVELOPMENT FCC ID: L2MK9310 RULES:2.1033 (b) (4) CIRCUIT DESCRIPTION This unit is a low power security transmitter. The oscillator is a LC lumped element oscillator made up of C2, VC, L,L2, and Q1. The inductor is printed on the printed circuit board. The digital codes are generated by manually pushing on the keys of the device which cause integrated circuit IC1 (HCS200) to be activated.The codes modulate the RF carrier at the base of Q1. The unit is completely self contained and is powered by a 12 Volt battery. The calculations for duty cycle are shown else where in the report and is 43.8%. ANTENNA AND GROUND: This unit uses a printed circuit board inductor as the antenna. There is no provision for an external antenna. OMEGA RESEARCH & DEVELOPMENT, INC.

RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a prese- lector. The bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100KHz and the video bandwidth was 300KHz. The ambient temperature of the UUT was 99oF with a humidity of 30%. APPLICANT: OMEGA RESEARCH & DEVELOPMENT FCC ID: L2MK9310 REPORT #: T:\CUS\O\OMEGA\213U0\213U0.RPT PAGE #: 1 TEST PROCEDURES CONTD. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was estab- lished by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor sup- plied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m ANSI STANDARD C63.4-1992 10.1.7 MEASUREMENT PROCEDURES: The UUT was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The UUT was placed in the center of the table. The table used for radiat- ed measurements is capable of continuous rotation. The spectrum was scanned from 30 MHz to 10th harmonic of the fundamental. Peak readings were taken in three (3) orthogonal planes and the high- est readings were converted to average readings based on the duration of "ON" time. Measurements were made by TIMCO ENGINEERING INC. at the registered open field test site located at 849 N.W. State Road 45, Newberry, Fl 32669. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and vertical planes.
