4.1.3 TEST PROCEDURE
a. The EUT was placed 0.8 meters from the horizontal ground plane with EUT being connected
to the power mains through a line impedance stabilization network (LISN). All other support
equipments powered from additional LISN(s). The LISN provide 50 Ohm/ 50uH of coupling
impedance for the measuring instrument.
b. Interconnecting cables that hang closer than 40 cm to the ground plane shall be folded back
and forth in the center forming a bundle 30 to 40 cm long.
c. I/O cables that are not connected to a peripheral shall be bundled in the center. The end of the
cable may be terminated, if required, using the correct terminating impedance. The overall
length shall not exceed 1 m.
d. LISN at least 80 cm from nearest part of EUT chassis.
e. For the actual test configuration, please refer to the related Item –EUT Test Photos.

4.1.6 EUT OPERATING CONDITIONS
The EUT exercise program (EMC.exe) used during radiated and/or conducted emission
measurement was designed to exercise the various system components in a manner similar to a
typical use. The program contained on a PC hard disk and is auto-starting on power-up. Once
loaded, the program sequentially exercises each system component in turn. The sequence used
is:
1. Read (write) from (to) mass storage device (EUT).
2. Send "H" pattern to video port device (Monitor).
3. Send " H " pattern to parallel port device (Printer).
4. Send " H " pattern to serial port device (Modem).
5. Repeated from 2 to 4 continuously.
As the keyboard and mouse are strictly input devices, no data is transmitted to (from) them during
test. They are, however, continuously scanned for data input activity.

4.2.3 TEST PROCEDURE
a. The measuring distance of at 10 m shall be used for measurements at frequency up to 1GHz.
For frequencies above 1GHz, any suitable measuring distance may be used.
b. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3m or 10
meter open area test site. The table was rotated 360 degrees to determine the position of the
highest radiation.
c. The height of the equipment or of the substitution antenna shall be 0.8 m; the height of the test
antenna shall vary between 1 m to 4 m. Both horizontal and vertical polarizations of the
antenna are set to make the measurement.
d. The initial step in collecting radiated emission data is a spectrum analyzer peak detector mode
pre-scanning the measurement frequency range. Significant peaks are then marked and then
Quasi Peak detector mode re-measured.
e. If the Peak Mode measured value compliance with and lower than Quasi Peak Mode Limit, the
EUT shall be deemed to meet QP Limits and then no additional QP Mode measurement
performed.
f. For the actual test configuration, please refer to the related Item –EUT Test Photos.
