Servo Monitor (Part No. 01E20845S01)
|. Purpose
DS-L mechanism built-in 3DE-7886R performs digital signal processing in the insideof Digital Servo LSI
and the outside alignment circuit builds in to this Digital Servo LSI and each alignments are automatic.
This DT Mech. Servo Monitor is jig for the automatic alignment circuitry.
Please refer to the following list for the reference;
1. LED indicates the alignment.
2. Diagnosis of automatic alignment.
3. LED indicates a failure item for easy failure analysis of servo circuitry.

3DE-7886R
lll. Operating Specifications
The automatic adjustment operations of the 3DE-7886R are performed by output of the commands of the various
-adjustment
items
from
the
main
microprocessor.
Adjustments
are
performed
in
response
to
these
commands
by
the
digital
servo
LSI.
This
servo
monitor
jig
receives
the
signal
returned
to
the
main
microprocessor
from
the
digital
servo
LSI
and
causes
the
LED
to
light
or
go
off.
The
adjustment
condition
(of
either
completed
or
not
yet
completed)
of
the
various
adjustment
items
can
be
checked
using
the
lighting
condition
of
this
LED.
The following test discs are required for the good/fault judgment:
1. A-BEX TCD-721 (6th track - 1.2mm) : Scratch test disc
2. A-BEX TCD-782 : Signal test disc
Measures to be Taken Corresponding
1. When a LED other than FAGC or TAGC lights, perform the fault causation analysis using the fault diagnosis chart
according to the LED indication.
2. When only the FAGC or TAGC LED turn on a lights (indicating that the focus / tracking fine gain adjustment is
not completed) , perform the focus / tracking servo gain adjustment. If the value is within the specification, the
adjustment is normal.

Measurements
A. RF Signal Level Measurement
The main beam of the returning light is received by the photodiode and the output voltage is obtained by current-voltage
conversion of A+B+C+D.
1. Block Diagram
Sample player Oscilloscope
2. Measurement Method
(a). Connect the ground terminal of the oscilloscope VRO (TA2066F (IC2102), pin 20) and measure the RFO signal
(of TA2066F (1C2102), pin 21).
(b). Play the first track of the measurement disc A-BEX TCD-782.
(c). Read the peak-to-peak value of the waveform.
Specification: 1.2+0.3, -0.2V
* When the value is outside of the specification (i.e., not good), check TA2066F (C2102) and the pick-up.
B. Jitter Measurement
The standard deviation of the pulse width when a trigger is applied to the rising edge of the 3T component of the RF signal.
1. Block Diagram
Sample player Jitter meter
2. Measurement Method
(a). Connect the ground terminal of the jitter meter to VRO (TA2066F (1C2102), pin 20) and measure the RFO signal
(of TA2Z066F (IC2102), pin 21).
(b). Play the first track of the measurement disc A-BEX TCD-782.
(c). Read the indicated value of the jitter meter.
Specification: 25nS or less
* When the value is outside of the specification, check TA2066F (IC2102) and the pick-up.
