Remarks: In the Above Table, the tighter limit applies at the band edges.

4.4 EUT CONFIGURATION ON MEASUREMENT

4.4.1 FOR POWER LINE

The equipments, which are listed at 4.2, are installed on Conducted Emission Test to meet the

Commission requirement and operating in a manner which tends to maximize its emission

characteristics in a normal application.

The device under test, installed in a representative system as described in section 4.2, was

placed on a non-conductive table whose total height equaled 80 cm. The EUT was powered

through one L.I.S.N. whose the signal output was terminated to the receiver. The other

peripherals were powered from another L.I.S.N. whose the signal output was terminated by 50

Ohms terminator.

4.5 CONDUCTED EMISSION DATA

The measurement range of conducted emission, which is from

0.15 MHz to 30 MHz

, was

investigated. The initial step in collecting conducted data is a spectrum analyzer peak scan of the

measurement range for all the test modes. Then the worst modes were reported the following

data pages.

The final measurement equal to Receiver reading plus a Correction factor when AMN insertion

loss bigger than 0.5dB, the receiver added the correction factor to the reading level automatically.

4.6 OPERATING CONDITIONS OF THE EUT

The exercise program used during conducted emission measurement was designed to exercise

the EUT in a manner similar to a typical use. The exercise sequence is listed as below:

1. Setup the EUT and simulators as shown on 4.2.

2. Turn on the power of all equipments.

3. Boot the Server from Hard Disk and setup the video to windows Server 2003, active all

devices.

4. Adjust to appropriate video resolution.

5. Connect the Far End Network Server and run test program “test.bat “.

6. The EUT exchange the information with the GesTek server via HUB.

7. Active other internal devices such as network function.

8. Run “DVD-Play” & “H.D.D. R/W” & “EMC” test program under windows Server 2003.

9. Server sent “H” pattern to monitor, make the “H” pattern full in the screen.

10. Server sent “H” pattern to parallel and serial port.

11. Repeat above steps.
