MEASURING METHOD AND WAVEFORMS
Measuring Disc:
CD/TCD-784
DVD/VT502 or TDV-520A
BD/ABD-520 or BLX-108
To check the waveforms on the FE/SACD UNIT, the GND (-) probe to "
Q7
VC" point.
q
~
Q6
points have the certain test points shown below.
•
The HF waveform (ATEST) is not normally output. The waveform can be output by setting the test mode. Cancel the
test mode to play a disc. For details, see "7. Test mode" (page 17~24).
Other signals are output.
•
When HF waveform (ATEST) is noisy or cannot discriminate the eye-pattern, replace the Travers Unit after
measuring the IOP.
※
When watching the HF waveform (ATEST), use the extending wire as short as possible.
※
It is better to use wires for extending between the probe and test points.
※
There is no test point at "
Q7
VC" . Please use the point on the + side of C217.
