Tenney Temperature Chamber TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written approval of TIMCO ENGINEERING, 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 75.8oF with a humidity of 69%. 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 POWER LINE CONDUCTED INTERFERENCE: The procedure used was ANSI STAN- DARD C63.4-1992 using a 50uH LISN. Both lines were observed. The bandwidth of the spectrum analyzer was 10kHz with an appro- priate sweep speed. The ambient temperature of the UUT was 75.8oF with a humidity of 69%.

FCC ID: GLE290927 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. CIRCUIT_DESCRIPTION: The UUT is placed in the transmit mode by pulling the trigger, which has two positions. The position determines the code that IC1 produces. The digital code is fed to the Base of the RF output stage Q1. The RF signal originates in the crystal con- trolled oscillator Q2. The output of Q2 is coupled through C6 to the base of Q1 where it is combined with the digital signal. The output of Q2 is fed to the tuned circuit made up of L2/C3/C2. From the capacitive tap on the tuned circuit the RF signal is fed to the low pass filter made up of L1/C1 and then to the antenna. ANTENNA_AND_GROUND_CIRCUITRY This unit makes use of a short, antenna. The antenna is induc- tively coupled. The antenna is self contained, no provision is made for an external antenna. This unit is powered from a 9.0V battery. No ground connection is provided. The unit relies on the ground tract of the printed circuit board. APPLICANT: SUNCON TOYS INDUSTRY LTD.
