FCC ID: BZB32BTH DATE: APRIL 7, 2000 REPORT #: T:\CUS\A\AZDEN\AZD59A0\59A0.RPT PAGE: 1 2.1033(C)(14) The data required by 2.1046 through 2.1057 is submitted below. 2.1046 RF_power_output. ERP was measured by the method described later in this report. The input power to the final stage was measured with a 9.0V supply connected in place of the 1.5V battery. INPUT POWER: FOR 9.0 V OPERATION (8.9V)(0.0059A) = 53.14MilliWatts OUTPUT POWER: FOR 9.0 V OPERATION 15.0 mWATTS ERP R.F.

The test receiver audio bandwidth was <50Hz to >20,000Hz. 2. Apply a 1000Hz tone and adjust the audio generator to produce 10% of the rated system deviation. 3. Measure frequency responce over the frequency range from 100Hz to 20,000Hz. The audio frequency response curve is shown in EXHIBIT # 10. (b) MODULATION LIMITING 2.1049 (c) Occupied_bandwidth: Using TIA/EIA 2.2.10 Accoustic Microphone Sensitivity test procedure to determine if the UUT could be put into modulation limiting and limiting could not be reached, the maximum deviation was only +40KHz. Using this test procedure the frequency of maximum sensitivity was determined to be 500Hz. a.

Since the UUT could not be put into modulation limiting with an acoustic coupling a dummy microphone was used to connect to the UUT and a test procedure similar to TIA/EIA-603 S2.2.11 was used to meas- ure the occupied bandwidth. Plots were made of the frequency of maxi- mum sensitivity, at 10KHz and …
