Adjustment Location:
CD SECTION
CD section adjustments are done automatically in this set.
In case of operation check, confirm that focus bias.
1. Connect the oscilloscope between IC1002 pin
qg
and pin
6
2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01)
3. Press the
4. Confirm that the oscilloscope waveform is as shown in the
figure below. (eye pattern)
A good eye pattern means that the diamond shape ( ) in the
center of the waveform can be clearly distinguished.
• RF signal reference waveform (eye pattern)
Test Point:
RF level :
0.85
±
0.2 Vp-p
VOLT/DIV : 50 mV (10 : 1 probe in use)
TIME/DIV : 500 nS
When observing the eye pattern, set the oscilloscope for AC range
and raise vertical sensitivity.
