CD ELECTRICAL MEASUREMENT

· Perform the measurement after the machine enters the test mode. · Place the CD mechanism horizontally level. · Equipment and tools required Measuring equipment: Oscilloscope (Use the probe of 10:1) Digital Multimeter (Use it in the DC Volt range.) Jitter meter (Kikusui 6235 or equivalent) Test disc: TCD-782 ATD-001

1. RF Waveform Check
1) 2) 3) Connect an oscilloscope to test point (IC101 4pin, RF), (IC101 11pin, Vref). Play back the 2nd track of the TCD-782. Check to see that the RF waveform has the maximum amplitude and the center of the wedge waveform has the clear blank.

2. Jitter Check
1) While an oscilloscope is kept connected in the same test point as in the 2. RF Waveform Check, connect the output terminal of an oscilloscope to the input terminal of a jitter meter. Set the VOLT range selector of an oscilloscope to 500 mV range or lower. Play back the 2nd track of the TCD-782. Check to see that a jitter meter indicates 40.0 ns or less.
