7.2. 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. 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.

9.3. 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 charging voltage by adapter 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.


9.4. 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.
