MEASURING METHOD AND WAVEFORMS
To check the waveforms on the Main P.W.B., the GND (-) probe of the oscilloscope to "Vref" point.(Except for lnner
SW, TRVSW)
Measuring Disc:
SACD/DAC Test Disc
CD/TCD-784
(It is better to use wires for extending between the probe and test points.)
• When watching the HF waveform, use the extending wire as short as possible.
• When HF waveform is noisy or cannot discriminate the eye-pattern, replace the Traverse Unit after measuring the lop.
•
