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 "

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 "6. Test mode".

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 "

VC" . Please use the point on the + side of C217.
