The equipment was set up as per the test configuration to simulate typical actual usage per the user's manual. The EUT is placed on a wooden table with a height of 0.8 meters is used and is placed on the ground plane as per ANSI C63.10: 2013. 2. Support equipment, if needed, was placed as per ANSI C63.10: 2013. 3. All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10: 2013. 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 Remark: EUT was tested at AC 120V and 240V, only the worst result of AC 120V was reported.
