MEASURING METHOD AND WAVEFORMS
To check the waveforms on the Main board, connect the GND (-) probe of the oscilloscope to the specified reference volt-
age.
Except for lnner SW, TRVSW
Measuring Disc :
CD/TCD-784
CD-R/TCD-R082W
CD-RW/TCD-W082W
(It is recommended to use extension wires between the probe and test points.)
• When watching the HF waveform, use the extending wire as short as possible.
• When the HF waveform is noisy or the eye-pattern is unidentifiable, replace the Traverse Unit.
• For points
q
to
Q5
, take measurements at the points shown in the diagram below.
