Report No.: UNIA22110312ER-61

3.3 TEST PROCEDURE
1. 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.

1. Measurement distance is 3m. 2. For the measurement range up to 30MHz in the following plots the field strength result from 3m. 3. Distance measurement are extrapolated to 300m and 30m distance respectively, by 40dB/decade.
According to part 15.31(f)(2), per antenna factor scaling. 4. Measurements below 1000MHz are performed with a peak detector and compared to average limits.
Measurements with an average detector are not required. Note: For battery operated equipment, the equipment tests shall be performed using a new battery.
