Video and General Performance Verification
1. Press FACTORY,
and then press the DISPLAY SELECT 4 button.
2. Press STATUS to display the status screen in tile 4.
3. Press a nd hold STATUS to display the pop-up menu, and then select Video
Session.
4. Connect a cable to any output on the TG2000 HDVG1.
5. Connect the other end of the cable to the 80 m section of the HD Cable clone.
6. Connect a second cable to the other port of the cable clone section.
7. Connect a cable from the cable clone to one of the SDI Input A connectors.
8. Terminat
e the other SDI Input A connector.
9. Connect an output from the DVG1 to one of the SDI Input B connectors.
10. Terminate the other SDI Input B connector.
11. Set the signal driving SDI Input B to 100% color b ars.
12. Set the time base on the second signal to 1 ppm high.
13. Verify that there are no CRC errors on the SDI A input.
14. Recor
d a Pass or fail as appropriate in the test record.
15. Disconnect the test setup.
Exte
rnal Reference
Formats Supported:
Bi-Level
Check that the device under test can reference to NTSC and PAL while viewing
digital signals.
1. Press FACTORY on the waveform rasterizer.
2. Press E XT to enable external reference mode.
3. Connect a 525/270 color bars signal from the DVG1 module to the SDI A
input of the unit under test and terminate the SDI loop-through connector.
4. Apply an NTSC black signal from the AVG1 output to the Reference input of
the waveform rasterizer. Terminate the othe r Reference input with a precision
termination.
5. Check that the lower-left corner of the waveform rasterizerdisplay shows
the proper standard for the reference.
6. Check that the Waveform and Vector displays are locked.
7. Log either Pass or fail in the test record.
8. Leave test setup as is for the next test.
