MEASURING METHOD AND WAVEFORMS
To check the waveforms, the GND (-) probe of the oscilloscope to specied reference voltage.
(Except for lnner SW, TRVSW)
Measuring Disc: CD/TCD-784
CD-R/TCD-R082W
CD-RW/TCD-W082W
(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.
