3. JITTER CHECK
1) While oscilloscope is kept connected in the same test point as in step2. RF WAVEFORM CHECK, connect the output terminal of an oscilloscope to the input terminal of the jitter meter. 2) Set the VOLT range selector of oscilloscope to 500mV range or below. 3) Play back 2nd track of TCD-782. 4) Check that jitter meter indicates 28.0ns or less.

4. PLAY ABILITY CHECK

5. LASER CURRENT CHECK
* Do not perform this measurement unless the laser is suspected to be defective. 1) Connect digital multi-meter across the resistor R402(10�). 2) Play back the TCD-782 and check the DC voltage value on the digital multimeter. 3) Calculate the laser current (Iop) by dividing the DC voltage across R402 by the resistor value (R402= 10�). Check that the laser current (Iop) is 60mA or less.
