5 MEASUREMENT PROCEDURE

5.1 PRELIMINARY 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 C63.4 (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.

2) Support equipment, if needed, was placed as per ANSI C63.4.

3) All I/O cables were positioned to simulate typical actual usage as per ANSI C63.4.

4) The EUT received AC power through a Line Impedance Stabilization Network (LISN) which

supplied power source and was grounded to the ground plane.

5) All support equipment received power from a second LISN supplying power of 110VAC/60Hz,

if any.

6) The EUT 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 150kHz to 30MHz for emissions in each of the test modes.

8) During the above scans, the emissions were maximized by cable manipulation.

9) The following test mode(s) were scanned during the preliminary test:

Mode(s):

1. 1280 × 1024 Resolution 75Hz

2. 1024 × 768 Resolution 75Hz

3. 800 × 600 Resolution 75Hz

10) After the preliminary scan, we found the following test mode producing the highest emission

level.

Mode: 1.

Then, the EUT configuration and cable configuration of the above highest emission level were

recorded for reference of final testing.

5.2 FINAL LINE CONDUCTED EMISSION TEST

1) EUT and support equipment was set up on the test bench as per step 10 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 Q.P. mode, then the

emission signal was re-checked using an Average detector.

3) The test data of the worst case condition(s) was reported on the Summary Data page.

5.3 PRELIMINARY RADIATED 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 turntable with a height of 0.8

meters is used which 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.

2) Support equipment, if needed, was placed as per ANSI C63.4.

3) All I/O cables were positioned to simulate typical actual usage as per ANSI C63.4.

4) The EUT received AC power source from the outlet socket under the turntable. All support

equipment received 110VAC/60Hz power from another socket under the turntable, if any.

5) The antenna was placed at 10 meter away from the EUT as stated in ANSI C63.4. The

antenna connected to the Analyzer via a cable and at times a pre-amplifier would be used.

6) 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.

7) The following test mode(s) were scanned during the preliminary test:

Mode(s):

1. 1280 × 1024 Resolution 75Hz

2. 1024 × 768 Resolution 75Hz

3. 800 × 600 Resolution 75Hz

8) After the preliminary scan, we found the following test mode producing the highest emission

level.

Model: 1.

Then, the EUT and cable configuration, antenna position, polarization and turntable position of the

above highest emission level were recorded for reference of final testing.

5.4 FINAL RADIATED EMISSION TEST

1) EUT and support equipment were set up on the turntable as per step 8 of the preliminary test.

2) 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.

3) 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.

4) The test data of the worst case condition(s) was reported on the Summary Data page.
