3. RADIATED EMISSION

3.1. MEASUREMENT PROCEDURE
 1. The EUT was placed on the top of the turntable 0.8 or 1.5 meter above ground. The phase center of
    the receiving antenna mounted on the top of a height-variable antenna tower was placed 3 meters far
    away from the turntable.
 2. Power on the EUT and all the supporting units. The turntable was rotated by 360 degrees to determine
    the position of the highest radiation.
 3. The height of the broadband receiving antenna was varied between one meter and four meters above
    ground to find the maximum emissions field strength of both horizontal and vertical polarization.
 4. For each suspected emissions, the antenna tower was scan (from 1 M to 4 M) and then the turntable
    was rotated (from 0 degree to 360 degrees) to find the maximum reading.
 5. Set the test-receiver system to Peak or CISPR quasi-peak Detect Function with specified bandwidth
    under Maximum Hold Mode.
 6. For emissions above 1GHz, use 1MHz VBW and RBW for peak reading. Then 1MHz RBW and 10Hz
    VBW for average reading in spectrum analyzer. 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. The measurement antenna may have to
    be higher or lower than the EUT, depending on the radiation pattern of the emission and staying aimed
    at the emission source for receiving the maximum signal. The final measurement antenna elevation
    shall be that which maximizes the emissions. The measurement antenna elevation for maximum
    emissions shall be restricted to a range of heights of from 1 m to 4 m above the ground or reference
    ground plane.
 7. When the radiated emissions limits are expressed in terms of the average value of the emissions, and
    pulsed operation is employed, the measurement field strength shall be determined by averaging over
    one complete pulse train, including blanking intervals, as long as the pulse train does not exceed 0.1
    seconds. As an alternative (provided the transmitter operates for longer than 0.1 seconds) or in cases
    where the pulse train exceeds 0.1 seconds, the measured field strength shall be determined from the
    average absolute voltage during a 0.1 second interval during which the field strength is at its maximum
    values.
 8.If the emissions level of the EUT in peak mode was 3 dB lower than the average limit specified, then
    testing will be stopped and peak values of EUT will be reported, otherwise, the emissions which do not
    have 3 dB margin will be repeated one by one using the quasi-peak method for below 1GHz.
 9. For testing above 1GHz, the emissions level of the EUT in peak mode was lower than average limit
    (that means the emissions level in peak mode also complies with the limit in average mode), then
    testing will be stopped and peak values of EUT will be reported, otherwise, the emissions will be
    measured in average mode again and reported.
 10. In case the emission is lower than 30MHz, loop antenna has to be used for measurement and the
    recorded data should be QP measured by receiver. High - Low scan is not required in this case.

6.3. PRELIMINARY PROCEDURE OF LINE CONDUCTED EMISSION TEST
1. The equipment was set up as per the test configuration to simulate typical actual usage per the user’s
   manual. When 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 (see Test Facility for the dimensions of the ground
   plane used). When the EUT is a floor-standing equipment, it is placed on the ground plane which has a
   3-12 mm non-conductive covering to insulate the EUT from the ground plane.
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. All support equipments received DC 3V/60Hz power from a LISN, if any.
5. The EUT received DC 5V power from adapter which received DC 3V/60Hz power from a LISN.
6. The 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.
8. During the above scans, the emissions were maximized by cable manipulation.
9. The test mode(s) were scanned during the preliminary test.

Then, the EUT configuration and cable configuration of the above highest emission level were recorded for
reference of final testing.

6.4. FINAL PROCEDURE OF LINE CONDUCTED EMISSION TEST
1. EUT and support equipment was set up on the test bench as per step 2 of the preliminary test.
2. A scan was taken on both power lines, Line 1 and Line 2, recording at least the six highest emissions.
   Emission frequency and amplitude were recorded into a computer in which correction factors were
   used to calculate the emission level and compare reading to the applicable limit. If EUT emission level
   was less –2dB to the A.V. limit in Peak mode, then the emission signal was re-checked using Q.P and
   Average detector.
3. The test data of the worst case condition(s) was reported on the Summary Data page.

Note: The EUT is power supplied by AAA battery.
