6.3. TEST PROCEDURES
(please refer to measurement standard or CCS SOP PA -031)
Procedure of Preliminary Test
l The EUT and Support equipment, if needed, was set up as per the test configuration to simulate
typical 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 C63.4 (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 12 mm non-conductive covering to
insulate the EUT from the ground plane.
l All I/O cables were positioned to simulate typical actual usage as per ANSI C63.4.
l The test equipment EUT installed received AC main power, through a Line Impedance
Stabilization Network (LISN), which supplied power source and was grounded to the ground
plane.
l All support equipment power received from a second LISN.
l The EUT test program was started. Emissions were measured on each current carrying line of
the EUT using an EMI Test Receiver connected to the LISN powering the EUT.
l The Receiver scanned from 150kHz to 30MHz for emissions in each of the test modes.
l During the above scans, the emissions were maximized by cable manipulation.
l The test mode(s) described in Item 3.1 were scanned during the preliminary test.
l After the preliminary scan, we found the test mode described in Item 3.1 producing the highest
emission level.
l The EUT configuration and cable configuration of the above highest emission levels were
recorded for reference of the final test.
Procedure of Final Test
l EUT and support equipment were set up on the test bench as per the configuration with highest
emission level in the preliminary test.
l 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.
l The test data of the worst-case condition(s) was recorded.

7.3. TEST PROCEDURES
(please refer to measurement standard or CCS SOP PA -031)
Procedure of Preliminary Test
l The equipment was set up as per the test configuration to simulate typical usage per the user’s
manual. When the EUT is a tabletop system, a wooden turntable with a height of 0.8 meters is
used which is placed on the ground plane. When the EUT is a floor standing equipment, it is
placed on the ground plane which has a 12 mm non-conductive covering to insulate the EUT
from the ground plane.
l Support equipment, if needed, was placed as per ANSI C63.4.
l All I/O cables were positioned to simulate typical usage as per ANSI C63.4.
l The EUT received AC power source from the outlet socket under the turntable. All support
equipment power received from another socket under the turntable.
l The antenna was placed at 10 meter away from the EUT as stated in ANSI C63.4. The antenna
connected to the Spectrum Analyzer via a cable and at times a pre-amplifier would be used.
l The Analyzer / Receiver quickly scanned from 30MHz to 1000MHz. The EUT test program was
started. Emissions were scanned and measured rotating the EUT to 360 degrees and positioning
the antenna 1 to 4 meters above the ground plane, in both the vertical and the horizontal
polarization, to maximize the emission reading level.
l The test mode(s) described in Item 3.1 were scanned during the preliminary test:
l After the preliminary scan, we found the test mode described in Item 3.1 producing the highest
emission level.
l The EUT and cable configuration, antenna position, polarization and turntable position of the
above highest emission level were recorded for the final test.

measured rotating the EUT to 360 degrees, varying cable placement and positioning the antenna
1 to 4 meters above the ground plane, in both the vertical and the horizontal polarization, to
maximize the emission reading level.
l Recorded at least the six highest emissions. Emission frequency, amplitude, antenna position,
polarization and turntable position were recorded into a computer in which correction factors
were used to calculate the emission level and compare reading to the applicable limit and only
Q.P. reading is presented.
l The test data of the worst-case condition(s) was recorded.
