Operational Description

Applicant: QG33279T27 Circuit Description Q2 the 27.145 MHz crystal oscillator drives the base of Q1 the final/buffer amplifier. Summed into the same base (Q1) is the modulation provided by IC1. The output of Q1 has the matching network consisting of L1, L2, and C1 that limit the harmonic content and affect the proper coupling of the antenna to the output stage. Antenna, Ground, and Power Source The antenna consists of a 45cm long telescoping chrome over brass tubing. There is no external ground connection. The ground is only that of print circuit board. Electric current is supplied by a 9 Volt primary storage cell.

FCC ID: QG33279T27 REPORT #: THRU-404007 Page 2 of 7 TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written approval of Thrulab & Engineering. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4- 1992 using a HEWLETT PACKARD spectrum analyzer with a preselector. 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 100 kHz and the video bandwidth was 300 kHz. The ambient temperature of the UUT was 20ºC with a humidity of 65%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor supplied 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 unit under test was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The table used for radiated measurements is capable of continuous rotation. 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. The situation was similar for the conducted measurement except that the table did not rotate. The EUT was setup as described in ANSIC63.4-1992 with the EUT 40 cm from the vertical ground wall. Not Applicable, battery operated. THRU Lab & Engineering.

TEST PROCEDURE : The procedure used was ANSI STANDARD C63.4-1992. The spectrum was scanned from 30 MHz to 1000 MHz. When an emission was found, the table was rotated to produce the maximum signal strength. The antenna was placed in both the horizontal and vertical planes and the worse case emissions were reported. The UUT was tested in 3 orthogonal planes. TEST RESULTS: THE UNIT DOES MEET THE FCC REQUIREMENTS. PERFORMED BY: K.M CHOI DATE: 04/22/2004 THRU Lab & Engineering.
