Video and General Performance Verification Procedures
3. Select a 525 270
MB/s 100% color bar signal from the TG2000 DVG1.
4. Connect a VGA to 5x BNC adapter cable to the waveform monitor PIX
MON output.
YPbPr.
5. Set the SD Al
gPixMontoYPbPr:
a. Press the CONFIG button.
b. Select Outputs, SD Anlg PixMon,andthenYPbPr.
6. Set the test oscilloscope to view the waveform. The following oscilloscope
settings normally provide a usable display:

Rising edge
Trigger Level 500 mV
7. Connect the Y/G channel of the VGA to 5x BNC adapter cable to the test
osci
lloscope.
8. Check that the Y waveform is 1 V
p-p
±5%, from sync tip to white level (first
col
or bar).
9. Check that the blanking (black) level is 0 mV ±50 mV.
10. Connect the Pb/B channel of the VGA to 5x BNC adapter cable to the test
oscilloscope.
11. Check that the Pb waveform is 700 mV
p-p
±5%, from the blanking (black)
level to the top of the waveform.
12. Check that the blanking (black) level is 0 mV ±50 mV.
13. Connect the Pr/R channel of the VGA to 5x BNC adapter cable to the test
oscilloscope.
14. Check that the Pr waveform is 700 mV
p-p
±5%, from the blanking (black)
level to the top of the waveform.
15. Check that the blanking (black) level is 0 mV ±50 mV.
16. Record Pass or Fail in the test record.
