Connection:
Procedure:
1. Connect the oscilloscope to the test points TJ503(RFI) and TJ610
1. Connect the oscilloscope to the test points TJ503(RFI) and TJ610
(VBIAS) on the MAIN board.
2. Set a disc. (YEDS-18)
3. Press the >B button.
4. Check the oscilloscope waveform is as shown below.
3. Press the >B button.
4. Check the oscilloscope waveform is as shown below.
A good eye pattern means that the diamond shape (
◊
) in the cen-
ter of the waveform can be clearly distinguished.
RF Signal reference Waveform (Eye Pattern)
To watch the eye pattern, set the oscilloscope to AC range and
increase the vertical sensitivity of the oscilloscope for easy
watch-ing.
increase the vertical sensitivity of the oscilloscope for easy
watch-ing.
5. Stop revolving of the disc motor by pressing the x button.
