3.0     SYSTEM TEST CONFIGURATION

3.1     JUSTIFICATION

The EUT was configured for testing in a typical fashion (as a customer would normally use it) by
attaching it to a host PC. This PC had all ofits ports connected to external peripherals.



3.2     EUT EXERCISE SOFTWARE

The EUT exercise program used during radiated and conducted testing has been designed to exercise the
various system components in a manner similar to a typical use. The software, contained on the hard
disk drive, sequentially exercises each system component. 1) an H prints on the monitor, 2) an H prints
on the printer 3) an H is sent to serial ports, 4) a file is read from the floppy diskette, 5) a file is read
from the hard drive and any other hard drive present, 6) a file is read from the CD—ROM drive. In cases
that implement the use of Universail Serial Bus (USB) ports, a looped batch program is initiated to
render a continuous flow of data through the USB ports. The complete cycle takes less than one second
and is repeated continually.    Systems that utilize network cards are connected to a server and are
configured to transmit and receive packets of data continuously. As the keyboard and mouse are strictly
input devices, no data was transmitted to them during test. They are, however, continuously scanned for
data input activity.

3.3     SPECIAL ACCESSORIES

The end user is advised that he/she should use the same type of cables as those mentioned in Table 1 of
this test report.

5.0       CONDUCTED EMISSION DATA

The initial step in collecting conducted data is a spectrum analyzer peak scan of the measurement range.
If the conducted emissions exceed the average limit with the instrument set to the quasi—peak mode,
then measurements are made in the average mode.

The conducted test was performed with the EUT exercise program loaded, and the emissions were
scanned between 150 kHz to 30 MHz on the NEUTRAL SIDE and HOT SIDE, herein referred to as L1
and L2, respectively.

6.1     Field Strength Calculation


The field strength is calculated by adding the Antenna Factor and Cable Factor, and subtracting the
Amplifier Gain (if any) from the measured reading. The basic equation with a sample calculation is as
follows:




                                     FI(dBuV/m)= SAR(dBuV) + SCF(dB/m)
                                             FI =Field Intensity
                                        SAR = Spectrum Analyzer Reading
                                          SCF = Site Correction Factor


The Site Correction Factor (SCF) used in the above equation is determined empirically, and is expressed
in the following equation:

                                  SCF(dB/m) = — PG(dB) + AF(dB/m) + CL(dB)

                                           SCF =Site Correction Factor
                                             PG =Pre—amplifier Gain
                                               AF _= Antenna Factor
                                                 CL =Cable Loss

The field intensity in microvolts per meter can then be determined according to the following equation:

                                                     FI(uV/m)= 1oFI(dBuV/m)/20


For example, assume a signal at a frequency of 125 MHz has a received level measured as 49.3 dBuV.
The total Site Correction Factor (antenna factor plus cable loss minus preamplifier gain) for 125 MHz is
—11.5 dB/m. The actual radiated field strength is calculated as follows:

                                       49.3 dBuV — 11.5 dB =37.8 dBuV/m

                                         10°"42% = 10489 = 77.6 uV/m

                  APPENDIX B: Conducted and Radiated Test Methodology



The power line conducted emission measurements were performed in a Series 81 type shielded enclosure
manufactured by Rayproof. The EUT was assembled on a wooden table 80 centimeters high. Power was fed to the
EUT through a 50 ohm / 50 microhenry Line Impedance Stabilization Network (LISN). The EUT LISN was fed
power through an A.C. filter box on the outside ofthe shielded enclosure. The filter box and EUT LISN housing are
bonded to the ground plane of the shielded enclosure. A second LISN, the peripheral LISN, provides isolation for
the EUT test peripherals. This peripheral LISN was also fed A.C. power. A metal power outlet box, which is bonded
to the ground plane and electrically connected to the peripheral LISN, powers the EUT host peripherals.

The spectrum analyzer was connected to the A.C. line through an isolation transformer. The 50—ohm output of the
EUT LISN was connected to the spectrum analyzer input through a Solar 400 kHz high—pass filter. The filter is used
to prevent overload of the spectrum analyzer from noise below 400 kHz. Conducted emission levels were measured
on each current—carrying line with the spectrum analyzer operating in the CISPR quasi—peak mode (or peak mode if
applicable). The analyzer‘s 6 dB bandwidth was set to 9 kHz. No video filter less than 10 times the resolution
bandwidth was used. Average measurements are performed in linear mode using a 10 kHz resolution bandwidth, a 1
Hz video bandwidth, and by increasing the sweep time in order to obtain a calibrated measurement. The emission
spectrum was scanned from (150/450) kHz to 30 MHz. The highest emission amplitudes relative to the appropriate
limit were measured and have been recorded in this report.




Before final measurements ofradiated emissions were made on the open—field three/ten meter range; the EUT was
scanned indoors at one and three meter distances. This was done in order to determine its emissions spectrum
signature. The physical arrangementof the test system and associated cabling was varied in order to determine the
effect on the EUT‘s emissions in amplitude, direction and frequency. This process was repeated during final radiated
emissions measurements on the open—field range, at each frequency, in order to insure that maximum emission
amplitudes were attained.

Final radiated emissions measurements were made on the three—meter, open—field test site. The EUT was placed on a
nonconductive turntable 0.8 meters above the ground plane. The spectrum was examined from 30 MHz to 1000
MHz.

At each frequency, the EUT was rotated 360 degrees, and the antenna was raised and lowered from one to four
meters in order to determine the maximum emission levels. Measurements were taken using both horizontal and
vertical antenna polarizations, The spectrum analyzer‘s 6 dB bandwidth was set to 120 kHz, and the analyzer was
operated in the CISPR quasi—peak detection mode. No video filter less than 10 times the resolution bandwidth was
used. When any clock exceeds 108 MHz, the EUT was tested between 1 to 2 Gigahertz in peak mode with the
resolution bandwidth set at 1 MHz as stated in ANSI C63.4. The highest emission amplitudes refative to the
appropriate limit were measured and recorded in this report.

Note:   Rhein Tech Laboratories, Inc. has implemented procedures to minimize errors that occur from test
instruments, calibration, procedures, and test setups. Test instrument and calibration errors are documentedfrom
the manufacturer or calibration lab. Other errors have been defined and calculated within the Rhein Tech quality
manual, section 6.1. Rhein Tech implements the following procedures to minimize errors that may occur: yearly as
well as daily calibration methods, technician training, and emphasis to employees on avoiding error.
