7 Report No.: Page 7 of 36 2 Laboratory Information 2.1 Accreditations & Endorsements US Federal Communications Commission TUV Rheinland of North America located at 2305 Mission College Blvd, Suite 105, Santa Clara, CA 95054, is recognized by the commission for performing testing services for the general public on a fee basis. This laboratory test facilities have been fully described in reports submitted to and accepted by the FCC (Registration No US5251). The laboratory scope of accreditation includes: Title 47 CFR Parts 15 and 18. The accreditation is updated every 3 years NIST / NVLAP TUV Rheinland of North America is accredited by the National Voluntary Laboratory Accreditation Program, which is administered under the auspices of the National Institute of Standards and Technology. The laboratory has been assessed and accredited in accordance with ISO Standard 17025:2005 (Lab Code: ). The scope of laboratory accreditation includes emission and immunity testing. The accreditation is updated annually Industry Canada Registration No.: 2932D-1. The 10 meter Semi-Anechoic Chamber has been accepted by Industry Canada to perform testing to 3 and 10 meters based on the test procedures described in ANSI C Japan VCCI The Voluntary Control Council for Interference by Information Technology Equipment (VCCI) is a group that consists of Information Technology Equipment (ITE) manufacturers and EMC test laboratories. The purpose of the Council is to take voluntary control measures against electromagnetic interference from Information Technology Equipment, and thereby contribute to the development of a socially beneficial and responsible state of affairs in the realm of Information Technology Equipment in Japan. TUV Rheinland of North America at 1279 Quarry Ln, Pleasanton, CA has been assessed and approved in accordance with the Regulations for Voluntary Control Measures. (Registration Nos. R-2366, C-2585, C-2586, T-1635) Acceptance by Mutual Recognition Arrangement The United States has an established agreement with specific countries under the Asia Pacific Laboratory Accreditation Corporation (APLAC) Mutual Recognition Arrangement.

8 Report No.: Page 8 of Test Facilities Test facilities are located at 1279 Quarry Lane, Pleasanton, California 94566, U.S.A. and 2305 Mission College, Santa Clara, 95054, U.S.A. (Santa Clara is the Pleasanton Annex). Emission Test Facility The Semi-Anechoic chamber and AC Line Conducted measurement facility used to collect the radiated and conducted data has been constructed in accordance with ANSI C63.7:1992. The site has been measured in accordance with and verified to comply with the theoretical normalized site attenuation requirements of ANSI C63.4:2003, at test distances of 3 and 10 meters. This site has been described in reports dated November 1st, 2006, submitted to the FCC, and accepted by letter dated November 28, The site is listed with the FCC and accredited by NVLAP (Lab Code ). Immunity Test Facility ESD, EFT, Surge, PQF: These tests are performed in an environmentally controlled room with a 3.7m x 3.7m x 3.175mm thick aluminum floor connected to PE ground. For ESD testing, tabletop equipment is placed on an insulated mat with a surface resistivity of 10 9 Ohms/square on a 1.6m x 0.8m x 0.8m high non-conductive table with a 3.175mm aluminum top (Horizontal Coupling Plane). The HCP is connected to the main ground plane via a low impedance ground strap through two 470 kω resistors. The Vertical Coupling Plane consists of an aluminum plate 50cm x 50cm x 3.175mm thick. The VCP is connected to the main ground plane via a low impedance ground strap through two 470 kω resistors. For each of the other tests, the HCP is removed. RF Field Immunity testing is performed in a 10m semi-anechoic chamber with absorber added to floor. RF Conducted and Magnetic Field Immunity testing is performed on a 4.9m x 3.7m x 3.175mm thick aluminum ground plane which is connected to one end of the anechoic chamber. All test areas allow a minimum distance of 1 meter from the EUT to walls or conducting objects
9 Report No.: Page 9 of Measurement Uncertainty Two types of measurement uncertainty are expressed in this report, per ISO Guide To The Expression Of Uncertainty In Measurement, 1 st Edition, The Combined Standard Uncertainty is the standard uncertainty of the result of a measurement when that result is obtained from the values of a number of other quantities, equal to the positive square root of a sum of terms, the terms being the variances or co-variances of these other quantities weighted according to how the measurement result varies with changes in these quantities. The term standard uncertainty is the result of a measurement expressed as a standard deviation. The Expanded Uncertainty defines an interval about the result of a measurement that may be expected to encompass a large fraction of the distribution of values that could reasonably be attributed to the measurand. The fraction may be viewed as the coverage probability or level of confidence of the interval. Sample Calculation radiated & conducted emissions The field strength is calculated by subtracting the Amplifier Gain and adding the Cable Loss and Antenna Correction Factor to the measured reading. The basic equation is as follows: Field Strength (dbµv/m) = RAW - AMP + CBL + ACF Where: RAW = Measured level before correction (dbµv) AMP = Amplifier Gain (db) CBL = Cable Loss (db) ACF = Antenna Correction Factor (db/m) dbµv / m 20 µv/m = 10 Sample radiated emissions 30 MHz Measurement +Antenna Factor Amplifier Gain+Cable loss=radiated Emissions (dbuv/m) 25 dbuv/m db 20 db db = 23.5 dbuv/m
10 Report No.: Page 10 of 36 Table 1: Summary of Uncertainties - Emissions U lab U cispr Radiated 10m 30 MHz 1,000 MHz 3.2 db 5.2 db Table 2: Measurement Uncertainty Immunity The estimated combined standard uncertainty for ESD immunity measurements is ± 4.1%. The estimated combined standard uncertainty for radiated immunity measurements is ± 2.05 db. The expanded uncertainty at a level of 95% confidence is obtained by multiplying the combined standard uncertainty by a coverage factor of 2. Compliance criteria are not based on measurement uncertainty. 2.4 Calibration Traceability All measurement instrumentation is traceable to the National Institute of Standards and Technology (NIST). Measurement method complies with ANSI/NCSL Z and ISO Standard 17025:2005. Equipment calibration records are kept on file at the test facility. 2.5 Measurement Equipment Used Equipment Manufacturer Model # Serial/Inst # EMI Receiver (Receiver Section) EMI Receiver (RF Filter Section) 9 khz 1 GHz Ant.
