Report # R0206144Rpt Page 16 of 27 15.247 Test Report AMBIT Microsystems Corporation FCC ID: MCLAIRMPI350 11 - SPURIOUS RADIATED EMISSION 11.1 Measurement Uncertainty All measurements involve certain levels of uncertainties, especially in field of EMC. The factors contributing to uncertainties are spectrum analyzer, cable loss, antenna factor calibration, antenna directivity, antenna factor variation with height, antenna phase center variation, antenna factor frequency interpolation, measurement distance variation, site imperfections, mismatch (average), and system repeatability. Based on NIS 81, The Treatment of Uncertainty in EMC Measurements, the best estimate of the uncertainty of a radiation emissions measurement at BACL is +4.0 dB. 11.2 EUT Setup The radiated emission tests were performed in the open area 3-meter test site, using the setup in accordance with the ANSI C63.4-2000. The specification used was the FCC 15 Subpart C limits. The EUT was installed in the notebook. The notebook was put on the center back edge of the test table. The spacing between the peripherals was 10 centimeters. External I/O cables were draped along the edge of the test table and bundle when necessary. The host PC system was connected with 120Vac/60Hz power source. 11.3 Spectrum Analyzer Setup According to FCC Rules, 47 CFR 15.33 (a) (1), the system was tested to 25GHz. During the radiated emission test, the spectrum analyzer was set with the following configurations:

Start Frequency ........................................................... 30 MHz Stop Frequency ........................................................... 25GHz Sweep Speed ............................................................... Auto IF Bandwidth .............................................................. 1 MHz Video Bandwidth ........................................................ 1 MHz Quasi-Peak Adapter Bandwidth.................................. 120 kHz Quasi-Peak Adapter Mode.......................................... Normal Resolution Bandwidth................................................. 1MHz Report # R0206144Rpt Page 17 of 27 15.247 Test Report AMBIT Microsystems Corporation FCC ID: MCLAIRMPI350 11.4 Test Procedure For the radiated emissions test, the Host PC system power cord was connected to the AC floor outlet since the power supply used in the EUT did not provide an accessory power outlet. Maximizing procedure was performed on the six (6) highest emissions to ensure EUT compliance is with all installation combinations. All data was recorded in the peak detection mode. Quasi-peak readings was performed only when an emission was found to be marginal (within -4 dBV of specification limits), and are distinguished with a "Qp" in the data table. 11.5 Corrected Amplitude & Margin Calculation The Corrected Amplitude is calculated by adding the Antenna Factor and Cable Factor, and subtracting the Amplifier Gain from the Amplitude reading. The basic equation is as follows:

Corr. Ampl. = Indicated Reading + Antenna Factor + Cable Factor - Amplifier Gain The Margin column of the following data tables indicates the degree of compliance with the applicable limit. For example, a margin of -7dBV means the emission is 7dBV below the maximum limit for Subpart C. The equation for margin calculation is as follows:

Margin = Corr. Ampl. Subpart C Limit Report # R0206144Rpt Page 18 of 27 15.247 Test Report AMBIT Microsystems Corporation FCC ID: MCLAIRMPI350 11.6 Summary of Test Results According to the data in section 11.7, the EUT complied with the FCC Title 47, Part 15, Subpart C, section 15.205, 15.207 and 15.247, and had the worst margin of:

Report # R0206144Rpt Page 25 of 27 15.247 Test Report AMBIT Microsystems Corporation FCC ID: MCLAIRMPI350 12 - CONDUCTED EMISSIONS 12.1 Measurement Uncertainty All measurements involve certain levels of uncertainties, especially in field of EMC. The factors contributing to uncertainties are spectrum analyzer, cable loss, and LISN. Based on NIS 81, The Treatment of Uncertainty in EMC Measurements, the best estimate of the uncertainty of any conducted emissions measurement at BACL is +2.4 dB. 12.2 EUT Setup The measurement was performed at the Open Area Test Site, using the same setup per ANSI C63.4-2000 measurement procedure. The specification used was FCC 15 Subpart C limits. The EUT was installed in the notebook. The notebook was put on the center back edge of the test table. The spacing between the peripherals was 10 centimeters. External I/O cables were draped along the edge of the test table and bundle when necessary. The host PC system was connected with 120Vac/60Hz power source. 12.3 Spectrum Analyzer Setup The spectrum analyzer was set with the following configurations during the conduction test:

Start Frequency............................................................................... 450 kHz Stop Frequency............................................................................... 30 MHz Sweep Speed................................................................................... Auto IF Bandwidth.................................................................................. 10 kHz Video Bandwidth............................................................................ 10 kHz Quasi-Peak Adapter Bandwidth ..................................................... 9 kHz Quasi-Peak Adapter Mode.............................................................. Normal 12.4 Test Procedure During the conducted emission test, the power cord of the host system was connected to the auxiliary outlet of the first LISN. Maximizing procedure was performed on the six (6) highest emissions of each modes tested to ensure EUT is compliant with all installation combination. All data was recorded in the peak detection mode. Quasi-peak readings were only performed when an emission was found to be marginal (within -4 dBV of specification limits). Quasi-peak readings are distinguished with a "Qp".
