Lab. & Engineering 3. Conducted Emission Test 3.1 EUT Setup The measurement was performed in the secreen room of test site, using the setup in accordance with ANSI C€63.4—1992 conducted emission measurement procedure. The EUT was connected with RS—232 cable to Input of Host Computer. The hostcomputer was placed on the center and back edge ofthe test table. The printer, modem were placed on one side of the host computer with the Monitor and EUT on the other side. The rear of the host computer and all support equipments were flushed with the rear and sides of the tabletop. The keyboard was placed in front of the host computer, flushed with the front of the tabletop. The mouse was placed flushed with the back of the keyboard. Spacing between the peripherals was approximately 10 centimeters. 3.2 Test Equipment Setup The spectrum analyzer was configured during the conduction test in as follows: Start Frequency . . . . . . . . . . l l l l e e e e es 450kHz Stop Frequency . . . . . . . . . . l . 2 l e 2 e e es 30MHz Resolution Bandwidth . . . . . . . . . . . . . . ..

QP 3.3 Test Procedure During the conducted emission test, the host computer power cord was connected to the auxiliary outlet ofthe LISN1 and all other peripherals power cords were connected to the multiple outlet adapter of the LISN2. Maximizing procedure was performed on the six (6) highest emissions to ensure EUT compliance using 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 (less than —4dBuV). Quasi—peak readings are distinguished with a "QP". The conducted emission test was performed with EUT exercise program loaded, and the emissions were scanned between 0.45MHz to 30MHz on the LINE side and NEUTRAL side, herein referred to as L and N, respectively. The final test data for this test configuration is recorded in the table listed under section 3.5 of this report. Report No.: THRU—FO30116B FCC Part 15 Class B Test Report Page 10 of 13

Lab. & Engineering 3.4 Summary of Test Results According to the data in section 3.5, the EUT complied with the FCC Part 15 Class B standards, and had the worst margin reading of: —12.3dB at 0.603MHz in the LINE side with Toshba Corporation AC Adaptor, Model PA2444U AC Adaptor 3.5 Conducted Emission Test Data Line Conducted Emission FCC Part15 Class B Frequency Amplitude Detector Phase Limit Margin (MHz) (dBuV) Qp/Ave/Peak Line/Neutral (dBuV/m) (uV/m) (dB) 0.544 31.4 QP N 48.0 250 —16.6 0.603 35.7 QP N 48.0 250 —12.3 0.743 33.4 QP N 48.0 250 —14.6 0.834 33.6 QP N 48.0 250 —14.4 0.901 33.9 QP H 48.0 250 —14.1 1.024 33.8 QP H 48.0 250 —14.2 1.843 35.1 QP H 48.0 250 —12.9 2.498 36.2 QP H 48.0 250 —11.8 19.218 33.1 QP H 48.0 250 —14.9 20.643 33.2 QP H 48.0 250 —14.8 21.946 35.6 QP H 48.0 250 —12.4 25.418 35.3 QP H 48.0 250 —12.7 3.6 Plot of Conducted Emission Test Data Plot(s) of conducted emission test data for the Toshba Corporration AC Adaptor, Model PA2444U AC Adaptor is presented in Appendix A of this report as reference.

Lab. & Engineering 4. Radiated Emission Test 4.1 EUT Setup The radiated emission tests were performed in the open area test site, using the setup in accordance with ANSI C63.4—1992 radiated emission measurement procedure. The VGA monitor with EUT and all peripherals were place on the test table same as section 3.1.. Spacing between the peripherals was approximately 10 centimeters. 4.2 Test Equipment Setup During the radiated emission test, the EMI test receiver was set with the following configurations: Start Frequency . . . . . . . . . . l . .2 l e 2 e . es 30MHz Stop Frequency . . . . . . . . . . l . 2 l e 2 e e es 1000MHz IF Bandwidth . . . . . l l l l e e e e e s 120kHz Sweep Time . . . . . . . . . . l l l k e e e e e e es 1O0msec Detector Mode . . . . . . . . . l 2 l e e e e e e . QP 4.3 Test Procedure For the radiated emission test, the host computer and all support equipments power cords was connected to the AC floor outlet. Maximizing procedure was performed on the six (6) highest emissions to verify that the EUT complied with all installation combination. The radiated emission test was performed with EUT exercise program loaded, and the emissions were scanned between 30MHz to 1000MHz. At each frequency, the EUT was rotated 360 degrees, and the antenna was raised and lowered from 1 to 4 meters in order to determine the maximum emission levels. Measurements were taken using both HORIZONTAL and VERTICAL antenna polarization. The final test data for this test configuration is recorded in the table listed under section 4.6 of this report. 4.4 Corrected Amplitude and Margin Calculation The Corrected Amplitude is calculated by adding the antenna and cable Correction Factor from the Indicated Amplitude reading. The basic equation is as follows: Corrected Amplitude = Indicated Amplitude + Antenna Factor + Cable Factor The Margin column of the data table in section 4.6 indicates the degree of compliance with the applicable limit. The equation for margin calculation is as follows: Margin = Corrected Amplitude — Applicable Limit Report No.: THRU—FO30116B FCC Part 15 Class B Test Report Page 12 of 13

Lab. & Engineering 4.5 Summary of Test Results According to the data in section 4.6, the EUT complied with the FCC Part 15 Class B standards, and had the worst margin of: —3.5dB at 60.448 MHz in the HORIZONTAL polarization at an antenna—to—EUT distance of 3 meters. 4.6 Radiated Emission Test Result Data Indicated Antenna Table Correction Corre.cted FCC Part15 Class B Factor |Amplitude Freq.
