18B6.3 TEST PROCEDURES
26BProcedure of Preliminary Test
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 3-12
mm non-conductive covering to insulate the EUT from the ground plane.
All I/O cables were positioned to simulate typical actual usage as per ANSI C63.4.
All support equipment power received from a second LISN.
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.
The Receiver scanned from 9 kHz to 30MHz for emissions in each of the test modes.
During the above scans, the emissions were maximized by cable manipulation.
The test mode(s) described in Item 3.1 were scanned during the preliminary test.
After the preliminary scan, we found the test mode described in Item 3.1 producing the
highest emission level.
The EUT configuration and worse cable configuration of the above highest emission
levels were recorded for reference of the final test.
27BProcedure of Final Test
EUT and support equipment were set up on the test bench as per the configuration with
highest emission level in the preliminary test.
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.
The test data of the worst-case condition(s) was recorded.

23B7.3 TEST PROCEDURES
28BProcedure of Preliminary Test
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 3-12 mm
non-conductive covering to insulate the EUT from the ground plane.
Support equipment, if needed, was placed as per ANSI C63.4.
All I/O cables were positioned to simulate typical usage as per ANSI C63.4.
Mains cables, telephone lines or other connections to auxiliary equipment located
outside the test are shall drape to the floor, be fitted with ferrite clamps or ferrite tubes
placed on the floor at the point where the cable reaches the floor and then routed to the
place where they leave the turntable. No extension cords shall be used to mains
receptacle.
The antenna was placed at 3 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.
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.
The test mode(s) described in Item 3.1 were scanned during the preliminary test:
After the preliminary scan, we found the test mode described in Item 3.1 producing the
highest emission level.
The EUT and worse cable configuration, antenna position, polarization and turntable
position of the above highest emission level were recorded for the final test.
When measuring emissions above 1GHz, the frequencies of maximum emission shall be
determined by manually positioning the antenna close to the EUT and by moving the
antenna over all sides of the EUT while observing a spectral display. It will be advantageous
to have prior knowledge of the frequencies of emissions above 1GHz.If the EUT is a device
with dimensions approximately equal to that of the measurement antenna beam width, the
measurement antenna shall be aligned with the EUT.

Procedure of Final Test
EUT and support equipment were set up on the turntable as per the configuration with
highest emission level in the preliminary test.
The Analyzer / Receiver scanned from 30MHz to 1000MHz. Emissions were scanned
and 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.
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.
For the measurement above 1GHz, use the cable, EUT arrangement, and mode of
operation determined in the exploratory testing to produce the emission that has the highest
amplitude relative to the limit.
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 antenna in
the “cone of radiation” from that area and pointed at the area both in azimuth and elevation,
with polarization oriented for maximum response.
The antenna may have to be higher or lower than the EUT, depending on the EUT’s size
and mounting height, but the antenna should be restricted to a range of height of from 1m to
4m above the ground or reference ground plane.
If the transmission line for the measurement antenna restricts its range of height and
polarization, the steps needed to ensure the correct measurement of the maximum
emissions, shall be described in detail in the report of the measurements.
1) using the procedures above to measure with peak detector function, if the result comply
with the average limit specified by the appropriate regulation, record the EUT
arrangement, mode of operation, and cable positions used for final radiated emission
measurement , this can be done with either diagrams or photographs.
2) Set the detector function of the measuring instrument to average mode, using the
procedures above and remeasure only those emissions that complied with the peak
limits but exceeded the average limits.
Recorded at least the six highest emissions.
