Modifications None Test Exercise (e.g software description, test signal, etc.) The DUT was placed in continuous transmit mode of operation. Applicable Standards TIA 603, FCC CFR 47 Parts 2 and 74 Applicant: AVTRONICS FCC ID: Y3I-AVTQUADBP6 Report: A\AVTRONICS\2768FT10\2768FT10TestReport.doc Page 6 of 16 TEST PROCEDURES Power Line Conducted Interference: The procedure used was TIA 603 using a 50uH LISN. Both lines were observed with the UUT transmitting. The bandwidth of the spectrum analyzer was 10 kHz with an appropriate sweep speed. Bandwidth 20 dB: The measurements were made with the spectrum analyzer's resolution bandwidth (RBW) = 1 MHz and the video bandwidth (VBW) = 3 MHz and the span set as shown on plot. Power Output: For a device with a fixed antenna, RF power is measured as ERP as the antenna is permanently attached. The substitution method was used as described in TIA-603- C. Antenna Conducted Emissions: The RBW = 100 kHz, VBW = 300 kHz and the span set to 10.0 MHz and the spectrum was scanned from 30 MHz to the 10 th Harmonic of the fundamental. Above 1 GHz the resolution bandwidth was 1 MHz and the VBW = 3 MHz and the span to 50 MHz. Radiation Interference: The test procedure used was TIA 603 using an Agilent spectrum receiver with pre-selector. The bandwidth (RBW) of the spectrum TIA 603 receiver was 100 kHz up to 1 GHz and 1 MHz above 1 GHz with an appropriate sweep speed. The VBW above 1 GHz was 3 MHz. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The ambient temperature of the UUT was 76F with a humidity of 55%.
