1.6 Calibration of Measuring Instrument
 The measuring equipment, which was utilized in performing the tests documented herein, has
 been calibrated in accordance with the manufacturers recommendations for utilizing calibration
 equipments, which is traceable to recognized national standards.
 Espectially, all antenna for measurement is calibrated in accordance with the requirements of C63.5
 (Version : 2006).


1.7 Measurement Uncertainty

 The measurement uncertainties shown below were calculated in accordance with the requirements
 of ANSI C63.4-2014.
 All measurement uncertainty values are shown with a coverage factor of k = 2 to indicate a 95 %
 level of confidence. The measurement data shown herein meets or exceeds the UCISPR measurement
 uncertainty values specified in CISPR 16-4-2 and, thus, can be compared directly to specified limits to
 determine compliance.

3. DESCRIPTION OF TEST

3.1 Measurement of Conducted Emission

 The test procedure was in accordance with ANSI C63.4-2014, Clause 7.3

 a. The EUT was placed 0.4 meters from the conducting wall of the shielded room with EUT being
    connected to the power mains through a line impedance stabilization network (LISN).
    If the EUT is connected to the PC through USB, the AC power-line adapter of the PC is directly
    connected to a line impedance stabilization network (LISN).
    Other support units were connected to the power mains through another LISN. The two LISNs provide
    50 Ohm/ 50uH of coupling impedance for the measuring instrument.
 b. Both conducted lines are measured in Quasi-Peak and Average mode, including the worst-case
    data points for each tested configuration.
 c. The frequency range from 150 kHz to 30 MHz was searched.

3.2 Measurement of Radiated Emission

 The test procedure was in accordance with ANSI C63.4-2014, Clause 8.3

 a. The EUT was placed on the top of a turn table 0.8 meters above the ground at a semi-anechoic chamber.
    The table was rotated 360 degrees to determine the position of the highest radiation.
 b. The EUT was set 3 m away from the interference-receiving antenna, which was mounted on
    the top of a variable-height antenna tower.
 c. The antenna height is varied from 1 m to 4 m above the ground to determine the maximum
    value of the field strength. Both horizontal and vertical polarizations of the antenna are set to
    make the measurement.
 d. For each suspected emission, the EUT was arranged to its worst case and then the antenna
    was tuned to heights from 1 m to 4 m and the turn table was turned from 0 degrees to 360
    degrees to find the maximum reading.
 e. The test-receiver system was set to Quasi-Peak detect function and specified bandwidth with
    maximum hold mode when the test frequency is below 1 GHz.
 f. The test-receiver system was set to Peak and Average detect function and specified
   bandwidth with maximum hold mode when the test frequency is above 1 GHz.
 g. Place the measurement antenna away from each area of the EUT determined to be a source of
    emissions at the specified measurement distance, while keeping the measurement antenna aimed
    at the source of emissions at each frequency of significant emissions, with polarization oriented
    for maximum response.(1 GHz to 40 GHz)
