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)
NOTES
Measuring Disc:
(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.
• P oint q ～ Q3 is measured with the point shown below.
※ Reference voltage of Q3 is GND_D1 Q5 5 , and reference voltage of other point is VC16 Q4 .
