To check the waveforms on the FEP, the GND (-) probe of
the oscilloscope to "VHALF" point.
(Except for lnner SW, TRVSW)
NOTES
Measuring Disc: DVD/VT502 or TDV-520A

(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.
• ~ points have the certain test points shown below.
