FCC ID: JDR ROSS01 TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written approval of TIMCO ENGINEERING, INC. The UUT was transmit- ting a test signal during the testing. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a prese- lector. 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 up to 1.0GHz and 1.0MHz with a video BW of 1.0MHz above 1.0GHz. For frequencies above 1.0GHz measurements were made at a distance of 1.0 meter and adjusted for 3 meters. The ambient temperature of the UUT was 74.3oF with a humidity of 69%. 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 POWER LINE CONDUCTED INTERFERENCE: The procedure used was ANSI STAN- DARD C63.4-1992 using a 50uH LISN. Both lines were observed. The bandwidth of the spectrum analyzer was 10kHz with an appro- priate sweep speed. The ambient temperature of the UUT was 74.3oF with a humidity of 69%. ANSI STANDARD C63.4-1992 10.1.7 MEASUREMENT PROCEDURES: The UUT was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The UUT was placed in the center of the table (1.5m side). The table used for radiated measurements is capable of continuous rotation. The measurements were made at 1.0 meter with the antenna being moved around to find the highest emission. 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. FCC ID: JDR ROSS01 REPORT NO.: T:\CUS\R\ROSTRA\ROS452U9\ROS452U9.RPT PAGE #: 2 CIRCUIT DESCRIPTION: The 10.5GHz transmitter is a short range obstacle sensor for automo- biles. Its range of use is expected to be 10 to 15 feet. This unit is a low power OBSTACLE SENSOR operating in the 10,500- 10,550MHz band. ANTENNA & GROUND: This unit uses a horn antenna. The antenna is self contained and there is no provision for connecting an external antenna. No ground connection is provided. The only ground used is the ground track on the PC board.
