8) 9)
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. Support equipment, if needed, was placed as per ANSI C63.4. All I/O cables were positioned to simulate typical actual usage as per ANSI C63.4. The EUT received DC from the PC which received 120VAC/60Hz power through a Line Impedance Stabilization Network (LISN) which supplied power source and was grounded to the ground plane. All support equipments received AC power from a second LISN supplying power of 120VAC/60Hz, if any. 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). 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 an Average detector. Analyzer / Receiver scanned from 150 kHz to 30MHz. The test data of the worst case condition(s) was reported on the Summary Data page. LINE CONDUCTED EMISSION LIMIT

5.2 RADIATED EMISSION TEST PROCEDURE 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 DC from battery. All support equipment received 120VAC/60Hz power from socket under the turntable, if any. 5) The antenna was placed at 3 meters away from the EUT as stated in CISPR 22. The antenna connected to the Analyzer via a cable and at times a pre-amplifier would be used. 6) 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. 7) 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 Q.P/Peak reading is presented. 8) The test data of the worst case condition(s) was reported on the Summary Data page.

VCCI: The 3m Semi-anechoic chamber and Shielded Room (7.5m×4.0m×3.0m) have been registered in Accordance with the Regulations for Voluntary Control Measure with Registration No.: R-2197 and C-2383 respectively. Date of Registration: September 29, 2008. Valid until September 28, 2011. FCC-Registration No.: 556682 The Laboratory has been registered and fully described in a report filed with the (FCC) Federal Communications Commission. The acceptance letter from the FCC is maintained in our files. Registration 556682, June. 27, 2008. Industry Canada (IC) The 3m Semi-anechoic chamber has been registered by Certification and Engineering Bureau of Industry Canada for radio equipment testing with Registration No.: 4620C-1
Instrument Tolerance:
All measuring equipment is in accord with ANSI C63.4 and CISPR 22 requirements that meet industry regulatory agency and accreditation agency requirement.
Ground Plane: Two conductive reference ground planes were used during the Line Conducted Emission, one in vertical and the other in horizontal. The dimensions of these ground planes are as below. The vertical ground plane was placed distancing 40 cm to the rear of the wooden test table on where the EUT and the support equipment were placed during test. The horizontal ground plane projected 50 cm beyond the footprint of the EUT system and distanced 80 cm to the wooden test table. For Radiated Emission Test, one horizontal conductive ground plane extended at least 1m beyond the periphery of the EUT and the largest measuring antenna, and covered the entire area between the EUT and the antenna. It has no holes or gaps having longitudinal dimensions larger than one-tenth of a wavelength at the highest frequency of measurement up to 1GHz.
