Report Number: SZ0310027 FCC ID: RPZAIR85031033 December 15, 2003 LAB CODE: 200577-0 Page7 Rev. 00 SECTION 1 FCC (LINE CONDUCTED & RADIATED EMISSION) MEASUREMENT PROCEDURE (PRELIMINARY LINE CONDUCTED EMISSION TEST) 1) The equipment was set up as per the test configuration to simulate typical actual usage per the user’s manual. When the EUT is a tabletop system, a wooden table with a height of 0.8 meters is used and is placed on the ground plane as per ANSI C63.4 (see Test Facility for the dimensions of the ground plane used). When the EUT is a floor-standing equipment, it is placed on the ground plane which has a 3-12 mm non-conductive covering to insulate the EUT from the ground plane. 2) Support equipment, if needed, was placed as per ANSI C63.4. 3) All I/O cables were positioned to simulate typical actual usage as per ANSI C63.4. 4) The EUT received DC power from PC, and PC received AC power through a Line Impedance Stabilization Network (LISN) which supplied power source and was grounded to the ground plane. 5) All support equipments received AC power from a second LISN supplying power, if any. 6) The EUT test program was started. Emissions were measured on each current carrying line of the EUT using a spectrum Analyzer / Receiver connected to the LISN powering the EUT. The LISN has two monitoring points: Line 1 (Hot Side) and Line 2 (Neutral Side). Two scans were taken: one with Line 1 connected to Analyzer / Receiver and Line 2 connected to a 50 ohm load; the second scan had Line 1 connected to a 50 ohm load and Line 2 connected to the Analyzer / Receiver. 7) Analyzer / Receiver scanned from 150kHz to 30MHz for emissions in each of the test modes. 8) During the above scans, the emissions were maximized by cable manipulation. 9) The following test mode…
