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.

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 "5. Test mode" (page 19~26).
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.
