Measuring Method And Waveforms; Mcu Cd Pcb : Test Point - Denon RCD-M38 Service Manual

MEASURING METHOD AND WAVEFORMS

To check the waveforms, the GND (-) probe of the oscilloscope to specified reference voltage.
(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.
• Point q ～ Q7 is measured with the point shown below.
