SD Video Tests
NOTE. Do the tests in this section only for waveform rasterizers that support
standard definition signals.
SD SDI Input Level Low
and High
This test uses the serial output with adjustable level to verify that the waveform
rasterizer can accept serial signals of various amplitudes.
1. Press FACTORY.
2. Press the DISPLAY SELECT 4 button.
3. Press and hold STATUS to display the pop-up menu and select Video Session.
Then press STATUS a gain to close the pop-up menu.
4. Connect a cable to the Opt S1 output of the TG2000 DVG1. The Opt S1
output is typically the second BNC from the top of that module.
5. Connect the other end of the cable to one of the SDI Input A connectors on
the waveform rasterizer.
6. Terminate the other SDI Input A connector.
7. On the TG2000 DVG1, set the output to the SDI Matrix signal.
8. You should see a stable picture and waveform on the waveform rasterizer
display. The status screen should display Valid for all the EDH parameters.
9. On the TG2000, adjust the serial amplitude downward to find the lowest level
that does not generate any EDH errors in a 10 second period.
10. Record this level in the test record.
11
.
In
crease the serial amplitude to 115%.
12. If any EDH errors are generated, reduce the amplitude until no errors are
ge
nerated for a 10 second period.
13. Record this level in the test record.
14. Repeat the test using SDI Input B on the waveform rasterizer.
15. Record this level in the test record.
