Jitter Vibration (Option
EYE or PHY)
This test shows
if there is excessive sensitivity to vibration.
1. Disconnect the HDST1 and set the instrument on a flat surface, with the top
cover in place.
2. Connect an HDVG1 output to WVR SDI A input.
3. Terminate the other SDI A connector with a 75 Ω SDI terminator.
4. Set the HDVG1 to generate a 1080i 59.94 100% Color Bars signal.
5. Press the left arrow key and then select Jitter1 HP Filter > 100 Hz.
6. If the jitter readout is not displayed, press the left arrow key and then select
Jitter Meter > Meter & Readout.
7. Plac
e a sheet of paper on the top cover to protect the surface, and and then
drop a BNC barrel connector onto the middle of the top cover from a height of
5 cm (2 inches) while watching the jitter readout.
8. Check that the jitter readout does not jump more than 0.4 UI.
9. EnterPassorFailinthetestrecord.
HD Recovered Sine-wave
Fidelity (Options EYE or
PHY)
This test checks that the HD recovered clock signal has no fidelity issues (such a s
stuck bits), after it has been filtered into a sine-wave and digitized.
1. Press FACTORY.
2. Connect an HDVG1 output to the SDI A input. Set the HDVG1 to generate a
1080i 59.94 100% Color Bars signal.
3. Terminate the other SDI A connector with a 75 Ω SDI terminator.
4. Press CONFIG, and then select Utilities > Calibration. Press SEL to start
calibration.
5. Press the up and dow n arrow keys to navigate to the end of the list of
Calibration Cases, highlighting Eye Recovered C lock Test. Press SEL to
begin this test.
6. Press the DISPLAY SELECT 1 button, and and then press FULL to view the
sine wave. Check that it is smooth and undistorted. There should be one
cycle displayed.
7. Press GAIN 5X and VAR. Use the GENERAL knob to adjust the gain to x10.
8. Check the waveform. There should be no discontinuities or jagged edges. Use
the VERTICAL knob to view the entire waveform.
9. Record Pass or fail in the test record.
10. Press the DISPLAY SELECT 4 button to return to the Calibration menu.
11. Press and hold STATUS, and then select Exit to exit calibration mode.
