The EUT is a tabletop system, a wooden table with a height of 0.1 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 AC120V/60Hz 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. 3.4 Test Result PASS All the test modes completed for test. only the worst result of Left(8DPSK High Channel) was reported as below:
