Video and General Performance Verication Procedures
Basic Setup
Use the followi
ng setup for all tests unless otherwise specied.
1. Connect the power cord to the rear of the waveform monitor.
2. Connect an XGA monitor to rear of instrument.
3. Connect the power cord to the AC mains and allow at least 20 minutes for the
waveform monitor to warm up before beginning any procedures.
Instrument Tests
The following procedures ap
ply to all base instruments except where labeled for
specic models. Do all tests except those that exclude your model.
HD SDI Input Level Lo w
andHigh(OptionHD)
This test uses the serial output with adjustable level to verify that the waveform
monitor can accept serial signals of various amplitudes.
1. Set the waveform monitor to the factory presets. (See page 60, Restore the
Factory Presets.)
2. Connect a 75 cable from a TG2000 HDVG1 output (Output 2) to the
HDST1 video input.
3. Connect a 75 cable from the HDST1 STRESS output to the SDI A input on
the waveform monitor.
4. On the TG2000 HDVG1, set the output to the SDI Matrix signal.
5. You should see a stable picture and waveform on the waveform monitor
display. Select a tile, press and hold the STATUS button, and select Video
Session to display the status screen. The status screen should display OK for
Y Chan CRC, C Chan CRC, Y Anc Checksum, and C Anc Checksum errors.
6. Press the STATUS button to close the menu.
7. Press FULL to display the status screen full tile.
8. On the TG2000 HDST1, adjust the serial amplitude downward to nd the
lowest level that does not generate any CRC errors in a 10 second period.
9. Record the HDST1 Amplitude Level in the test record.
10. Increase the HDST1 Amplitude Level to 130 %.
11. If any EDH errors are generated, reduce the amplitude until no errors are
generated for a 1 0 second period.
12. Record the HDST1 Amplitude Level in the test record.
13. Move the input cable from the SDI A input to the SDI B input.
14. Repeat steps 8 through 12 for the SDI B input.
15. Record this level in the test record.
