FCC ID Label Sample for FCCID: SZ23520R49_ FCC ID: SZ23520R49

1. Introduction a. Four RC cars can be played individually in same frequency band b. Using Timing sharing for data transmission c. Using 4 different ID to distinguish from 4 different RC cars d. 4 functions including forward, backward, left and right 2. TX (49MHz) TX is supplied by a 9V battery and regulate 5V to the IC GPRC11A-005C. There is a four position selector S5 to select different ID for the TX. In the TX, there are four function keys S1, S2, S3 & S4 to control the RC car (left, right, backward & forward). The modulating signal from IOC1 of GPRC11A-005C will be modulated by carrier frequency 49.86MHz. The modulated signal will be amplified and pass through Q2 & matching network to antenna. The matching network consists of L3, C10 & L4. 3. RX (49MHz) RX is supplied by AAAx3 batteries to the IC GPRC11A-006C. There is a four position selector PDF 文件使用 "pdfFactory" ?用版本?建 www.fineprint.com.cn J1 to select different ID for the RC car. The modulated signal is received by the antenna and demodulated. The demodulated signal will be amplified through Q2 & Q3 to GPRC11A-006C for decoding. The outputs will control two motors driving left & right and forward & backward respectively.] PDF 文件使用 "pdfFactory" ?用版本?建 www.fineprint.com.cn

FCC ID: SZ23520R49 REPORT :THRU-505003 Page 2 of 3 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 100KHZ and the video bandwidth was 300KHZ. The ambient temperature of the UUT was 19ºC with a humidity of 35%. 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. ANSI STANDARD C63.4-1992 12.1.1.1 SUPERREGENERATIVE RECEIVER: A signal Generator was set to the unit under test operating frequency. An un- Modulated continuous wave (CW) signal was radiated at the super regenerative receiver operating frequency to cohere the characteristic broadband emissions from the receiver. 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.
