MEASURING METHOD AND WAVEFORMS
To check the waveforms on the FEP, the GND (
-
) probe of
the oscilloscope to “VHALF” point.
(Except for lnner SW, TRVSW)
Measuring Disc: DVD/VT502 or TDV-520A
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.
~ points have the certain test points shown below.

(テストポイントとプローブ間に延長ワイヤを使用するの
がより良い方法です。
HF 波形を観測する場合、できるだけ短い延長ワイヤを
使用してください。
