9.2. MEASUREMENT PROCEDURE
1. The measuring distance of 3m shall be used for measurements. The EUT was placed on the top of a
rotating table 0.8 meter above the ground at a 3 meter semi-anechoic chamber. The table was rotated
360 degrees to determine the position of the highest radiation(Below 1GHz)
2. The measuring distance of 3m shall used for measurements. The EUT was placed on the top of a rotating
table 1.5 meter above the ground at a 3 meter semi-anechoic chamber. The table was rotated 360
degrees to determine the position of the highest radiation(Above 1GHz)
3. The height of the test antenna shall vary between 1m to 4m.Both horizontal and vertical polarization
Of the antenna are set to make the measurement.
4. The initial step in collecting radiated emission data is a receive peak detector mode. Pre-scanning the
measurement frequency range. Significant peaks are then marked and then Quasi Peak detector mode
re-measured.
5. All readings are peak unless otherwise stated QP in column of Note. Peak denoted that the Peak
reading compliance with the QP limits and then QP Mode measurement didn’t perform(Below 1GHz)
6. All readings are Peak mode value unless otherwise stated AVG in column of Note. If the Peak mode
measured value compliance with the Peak limits and lower than AVG Limits, the EUT shall be deemed to
meet Peak & AVG limits and then only Peak mode was measured, but AVG mode didn’t perform.(Above
1GHz)

12.3. 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 AC120V/60Hz power from a LISN, if any.
5. The EUT received DC charging voltage by adapter or PC which received 120V/60Hzpower by 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.
12.4. 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.
