The EUT is a three button transmitter, and part of a system which connects to a garage door opener. The EUT incorporates an internal antenna which is etched directly into the PCB. Related Submittal(s)/Grant(s) The EUT will be used with a receiver (application already submitted and approved under FCC ID: KJ8SAR-3725GE). FCC ID: KJ8HHT-372BSW SECTION 2 TESTS AND MEASUREMENTS FCC ID: KJ8HHT-372BSW TESTS AND MEASUREMENTS Configuration of Tested System The sample was tested per ANSI C63.4, Methods of Measurement from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz (1992). Conducted and radiated emissions data were taken with the test receiver or spectrum analyzer's resolution bandwidth adjusted to 9 kHz and 120 kHz, respectively. All measurements are peak unless stated otherwise. The video filter associated with the spectrum analyzer was off throughout the evaluation process. Interconnecting cables were manipulated as necessary to maximize emissions. A block diagram of the tested system is shown in Figure 1. Test configuration photographs for spurious and fundamental emissions are shown in Figure 2. Since the EUT is a hand held device, it was placed into a continuous mode of transmit and rotated about all 3 axis to obtain worse case results. All testing was performed with the EUT lying face up, flat on the table. Test Facility Testing was performed at US Tech's measurement facility at 3505 Francis Circle, Alpharetta, GA. This site has been fully described and submitted to the FCC, and accepted in their letter marked 31040/SIT. Additionally this site has also been fully described and submitted to Industry Canada (IC), and has been approved under file number IC2982. Test Equipment Table 2 describes test equipment used to evaluate this product.

The transmitter is a 3 button transmitter. The EUT continues to transmit while each button is being pressed. The EUT ceases transmission almost immediately upon being released and appears to finish the current packet being transmitted. Therefore the longest period of time the transmitter should take to deactivate is a packet length, or 45.75 msec as shown in Figure 3. FCC ID: KJ8HHT-372BSW FIGURE 3 Periodic Operation 15.231(a)(c1) FCC ID: KJ8HHT-372BSW Field Strength of Fundamental Emission (47 CFR 15.231b) Measurements were made using a peak detector. Field strength of the peak fundamental emission is shown in Table 3 and Figure 4. Duty Cycle Correction During 100 msec: Each function key sends a different series of characters, but each packet period (105.75 msec) never exceeds a series of 73* long (350.0 μs) and short (150.0 μs) pulses. Assuming any combination of short or long pulses may be obtained due to encoding the worse case transmit duty cycle would be con…
