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 C63.10. 2, Support equipment, if needed, was placed as per ANSI C63.10. 3, All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10. 4, If a EUT received DC power from the USB Port of Notebook PC, the PC's adapter received 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, 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 150 KHz to 30MHz for emissions in each of the test modes. AC Power Conducted Emission Limit For intentional device, according to § 15.207(a) AC Power Conducted Emission Limits is as following Frequency range (MHz) Limit (dBuV) Quasi-peak Average 0.15-0.5 66 to 56* 56 to 46* 0.5-5 56 46 5-30 60 50 * Decreases with the logarithm of the frequency.
