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 85oF with a humidity of 81%. 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 REPORT #: F:\CUS\T\TOYMAX\TOY207U8.RPT PAGE #: 1 TEST PROCEDURES CONTINUED APPLICANT: TOYMAX INC. FCC ID: NLKTMI9080849T 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: In the transmit mode the momentary switches SW1 & SW2 provide input to the function encoding control - Q1 & Q2. The output of the multi-vibrator modulates the crystal controlled oscillator - Q3. Q3 is connected to the RF Output - Q4. This signal is fed to the antenna via the output filter made up of a tuned circuit containing parts C10, C12, L3 & L4. ANTENNA AND GROUND CIRCUITRY This unit makes use of a external 10" whip antenna. The antenna is inductively coupled. This unit is powered from a 9.0V bat- tery. No ground connection is provided. The unit relies on the ground tract of the printed circuit board.

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: S. S. SANDERS DATE: AUGUST 5, 1998 REPORT #: F:\CUS\T\TOYMAX\TOY207U8.RPT PAGE #: 3 APPLICANT: TOYMAX INC. FCC ID: NLKTMI9080849T NAME OF TEST: Occupied Bandwidth RULES PART NO.: 15.235 REQUIREMENTS: The field strength of any emissions appearing between the band edges and up to 10 kHz above and below the band edges shall be attenuated at least 26 dB below the level of the unmodu- lated carrier or to the general limits of 15.209, whichever permits the higher emission levels. THE GRAPH IN EXHIBIT 11 REPRESENTS THE EMISSIONS TAKEN FOR THIS DE- VICE. METHOD OF MEASUREMENT: A small sample of the transmitter output was fed into the spectrum analyzer and the attached plot was taken. The vertical scale is set to -10 dBm per division. The horizontal scale is set to 5 kHz per division. TEST RES…
