EYE-PATTERN SIGNAL – JITTER MEASUREMENT

Measure the signal on the input of the Signal processor
using an

analog

oscilloscope. Please find the exact

measuring point in your Service Manual.

See below examples of the signal. Amplitude should read at
least 700mVpp using SBC444A.

good

bad

If the oscilloscope shows a signal like the ‘bad’ one, and/or
the amplitude decreases within 1 minute - the CD drive has
to be replaced.

6

CD DRIVE – LASER CURRENT MEASUREMENT

The laser current can be measured as a voltage drop on a
resistor. The resistor is marked in every Service Manual.
The value depends on the type of CD drive.

Use SBC444A (CD-DA) for measurement.

7

CD DRIVE – OFFSET MEASUREMENT

The photodiodes of the CD-drive may have an offset. These
offsets have to be compensated by the signal processor.
High offsets can lead to poor playability of some CDs
(skipping tracks).

To measure the offset values, start the

Service Test

Program

- section “Focus Test” without a CD.

The offsets can be measured with a DC Millivoltmeter
directly on the connector (see drawing below). Pin
numbering varies from drive to drive.

The values from diode A-D should read 0±10mV.
Diodes E and F are less critical.

If one of the offsets is higher than ±10mV the CD drive has
to be replaced. Otherwise replace the Signal Processor.
