Equipment required
1) Oscilloscope: single trace or dual trace, bandwidth of 100 MHz
or more, (input impedance of 10 Mohms or higher)
(1) Video level adjustment (DVD board)
<Purpose>
To align the video output signal level with the NTSC standard. If
not adjusted correctly, luminance of the video output signal may be
too bright or too dark.
Connection
Adjustment procedure:
1)
Connect an oscilloscope to the VIDEO OUT terminal.
2)
Adjust the video output signal level to 1.0
±
0.05 Vp-p.
(2) S-terminal video level check
<Purpose>
To check the S-terminal video output signal for the correct level. If
the S-terminal video output is not correct, picture will not appear
even when the monitor TV is connected to the S-terminal cable.
Connection
Adjustment procedure:
1)
Connect an oscilloscope to the S-VIDEO OUT terminal.
2)
Confirm that the S-Y level is 1.0
±
0.1 Vp-p.
3)
Connect an oscilloscope to the S-VIDEO OUT (S-C) terminal.
4)
Confirm that the S-C burst signal level is 286
±
80 mVp-p.
