Procedure:
1.
Keep the set horizontal.
(
If
the set is not horizontal, this adjustment cannot be )
performed due to the gravity against the 2-axis device.
2.
Insert disc (YEDS-18) and press [> PLA Y button.
3.
Connect oscilloscope to
TP
(FEO) and
TP
(VC)
on
BD
board.
4.
Adjustment RV101
on
BD
board so
that
the
waveform
is as shown in the figure below. (focus gain adjustment)
VOLT/DIV:
lOOmV
TIME/DIV:
2mS
• Incorrent Examples

5.
Connect oscilloscope to
TP
(TEO) and
TP

on
BD
board.
6.
Adjusted MV102
on
BD
board so
that
the
waveform
is
as
shown
the
figure below. (tracking gain adjustment)
VOLT/DIV:
