2 — SYSTEM TEST CONFIGURATION
2.1 Justification
The system was configured for testing in a typical fashion (as normally used by a typical user).

The following /O ports were provided by the motherboard: two serial ports, one parallel port, two USB
port, one PS/2 keyboard port, one PS/2 mouse port, one floppy interface connector, and one IDE interface
connectors. The CD—ROM drive provideds the audio out jack and the Network card provide the AUX,
BNC and RJ45 TP connector.

The parallel port (LPT1), two serial ports (COM! and COM2), PS/2 mouse and keyboard ports, two USB
ports, TP port, BNC port, and audio jack were also tested along with a 200 Watt power supply.

Since the fundamental frequency is the same with all processor speeds, 66MHz BUS in this case, the EUT
was tested with the Intel Pentium® II 333MHz CPU to represent worst case results.

The BUS and processor speeds were achieved by installing the appropriate processor and changing the
jumper settings on the motherboard. Following is the supported BUS and processor speeds:
        Intel Pentium® II:
        66 MHz BUS for 333MHz processor.


2.2 EUT Exercise Software
The EUT exercising program used during radiated and conducted testing was designed to exercise the
various system components in a manner similar to a typical use. The software, GWBASIC 2Modem,
contained on the hard drive, is started in a DOS window under the Windows 95 operating system. Once
loaded, the program sequentially exercises each system component.

The sequence used is as follows:

    1) Lines of Hs scrolis across the VGA monitor
    2) The printer outputs Hs
    3) The two modems receive Hs
    4) Send a signal to the two USB cables, which were terminated by a 100 ohms resistor.

The complete cycle takes approximately 5 — 10 seconds and the process is continuously repeated.


2.3 Special Accessories
As shown in section 2.5, all interface cables used for compliance testing are shielded as normally supplied
by INMAC, Y.C. Cable, Monster Cable and from their respective support equipment manufacturers. The
printer, the modem and VGA monitor featured shielded metal connectors.


2.4 Block Diagram

There is not block diagram available at the time of testing.
The system has only one full speed. In the full—speed mode, the 14.3MHz crystal on the motherboard drives
the frequency synthesizer to produce the 66MHz BUS clock to the CPU and other components on the
motherboard. Internally, the CPU is running at 333MHz.

3 — CONDUCTED EMISSIONS TEST DATA
3.1 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 mcasurement at BACL is +2.4 dB.


3.2 EUT Setup
The measurement was performed at the Open Area Test Site, using the same setup per ANSI C63.4 — 1992
measurement procedure. Specification used was with the FCC Class B limits.

The EUT was connected to a 110 VAC / 60 Hz power source and it was placed center and the back edge of
the test table. The VGA monitor and the tape were placed on one side of EUT, printer and the modem
were on the other side. A pair of speakers was placed directly in front of the printer and the modem. The
rear of the EUT and peripherals were placed flushed with the rear of the tabletop.

The keyboard was placed directly in front of the EUT, flushed with the front of the tabletop. The PS/2
mouse and the joystick were place next to the keyboard on one side, the Microphone was on the other side.
The mouse was flushed with the back of the keyboard.

The spacing between the peripherals was 10 centimeters.

Input / Output cables were draped over edge ofthe test table and bundle when necessary.


3.3 Spectrum Analyzer Setup

The spectrum analyzer was set with the following configurations during the conducted emission test:

     Start Frequency...
     Stop Frequency
     Sweep Speed ..
     IF Bandwidth..
     Video Bandwidth
     Quasi—Peak Adapter B      dth ...
     Quasi—Peak Adapter Mode ...........


3.4 Test Procedure

During the conducted emission test, the EUT power cord was connected to the auxtliary outlet ofthe first
LISN with the VGA monitor and all support equipment power cords connected to the second.

Since the fundamental frequency ii g the same with all processor speeds, 66MHz BUS in this case, the EUT
was tested using the Intel Pentium® II 333 MHz CPU with the PREMIO (TG—2006—B) 200 Watt power
supply to represent worst case results for the final qualification test. Therefore, these results were used for
final test data recorded in the table listed under section 3.6 of this report.

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 —4 dBuV). Quasi—peak readings are
distinguished with a "Qp".

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.


4.2 EUT Setup

The radiated emission tests were performed in the open area 3 metertest site, using the setup in accordance
with the ANSI €63.4 — 1992. The specification used was the FCC Class B limits.

The EUT was connected to a 110 VAC / 60 Hz power source and it was placed center and the back edge of
the test table. The VGA monitor and the tape were placed on one side of EUT, printer and the modem
were on the other side. A pair of speakers was placed directly in front of the printer and the modem. The
rear of the EUT and peripherals were placed flushed with the rear of the tabletop.
The keyboard was placed directly in front of the EUT, flushed with the front of the tabletop. The PS/2
mouse and the joystick were place next to the keyboard on one side, the Microphone was on the other side.
The mouse was flushed with the back of the keyboard.
The spacing between the peripherals was 10 centimeters.

Input / Output cables were draped over edge of the test table and bundle when necessary.


4.3 Spectrum Analyzer Setup
According to FCC Rules, 47 CFR 15.33, since the internal processor speed operates between 108—500
MHz, the system was tested to 2000 MHz.

During the radiated emission test, the spectrum analyzer was set with the following configurations:

                        Start Frequency ...
                        Stop Frequency
                        Sweep Speed ....

4.4 Test Procedure
For the radiated emissionstest, both the EUT and VGA monitor and all support equipment power cords
was connected to the AC floor outlet since the power supply (TG—2006—B) 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 (less than —4 dBuV), and are distinguished
with a "Qp" in the data table.
Since the fundamental frequency ii g the same with all processor speeds, 66MHz BUS in this case, the EUT
was tested using the Intel Pentium® II 333 MHz CPU at 66 MHz BUS speed to represent worst case results
for the final qualification test. . Therefore, these results were used for final test data recorded in the table
listed under section 4.7 of this report as reference.
The parallel port (LPT1}, two serial ports (COM1 and COM2), two USB ports, TP port, BNC port, PS/2
mouse and keyboard ports were also tested.


4.5 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 —7dBuV means the emission is 7dBuV below the maximum limit for
Class B. The equation for margin calculation is as follows:

        Margin = Corr, Ampl. — Class B Limit


4.6 Summary of Test Results
According to the data in section 4.7, the EUT complied with the FCC Class B standards and these test
results is deemed satisfactory evidence of compliance with ICES—003 ofthe Canadian Interference—
Causing Equipment Regulations, and had the worst margin of.


        —9.4 dBuV at 312.05 MHz in the Vertical polarization with the Intel Pentium® II 333 MHz CPU at
        66 MHz BUS.


        —8.4 dBuV at 312.05 MHz in the Vertical polarization with the Intel Pentium® II 333 MHz CPU at
        66 MHz BUS — After Maximize procedure.
