OPERATIONAL DESCRIPTION EXCERPT FROM TEST REPORT This RF transmitter works with a battery voltage of 3V. A single lithium battery of type CR2032 will be used. The microcomputer (I001) monitors the transmitter keypad buttons and generates the corresponding data word when a button is pressed. To meet high security require- ments, the data word is encoded using an 64 bit encryption algorithm. The transmitter identification data is stored in a non-volatile memory (EEPROM) I003. The data word is sent to the final transmitter (a stage of IC002) in a serial pulse form, Manchester encoded. The pulse train switches the RF power amplifier on and off. The RF emission is independent of the data content of the switched carrier which has a duty cycle of 0.5 during the pulse trains without considering the breaks between two subsequent pulse trains of an actuation. The transmitter antenna is realized in the form of a magnetic loop. The transmission freqeuncy of 315 MHz is generated by a quartz stabilized PLL oscillator which is also part of IC002.

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 81oF with a humidity of 60%.

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. RULES:2.1033(b)(4) CIRCUIT DESCRIPTION This RF transmitter works with a battery voltage of 3V.
