This test checks the jitter noise floor of the waveform monitor. Since some jitter
may be introduced by the signal source, you may need to characterize the
TG2000 output jitter with an oscilloscope. Most DVG1 modules have an output
noise floor in the 200 ps range.
1.
Press FACTORY.
2.
Connect the DVG1 upper output to SDI A input.
3.
Set the DVG1 to generate a 525--270 100% Color Bars signal.
4.
Press EYE. (If there is no EYE button, press and hold MEAS, and then
select Display Type > Eye Display.)
5.
Press <, and then select Jitter1 HP Filter > 100 Hz.
6.
Check that the jitter readout indicates approximately 250 ps (0.07 UI),
depending on TG2000 output jitter.
7.
Enter Pass or Fail in the test record for SD Jitter Readout Noise.
8.
Proceed to the next step if option PHY is present. Otherwise skip to step 18.
9.
Press FULL.
10.
Press <, and then select Display Type > Jitter Display.
11.
Press <, and then select Jitter1 HP Filter > 100 Hz.
12.
Press the DISPLAY SELECT 1 button briefly to close the menu.
13.
Press 5X GAIN.
14.
Measure the amplitude of the jitter waveform using the graticule or cursors.
15.
Using the graticule or the cursors, measure the jitter amplitude.
16.
Check that the jitter amplitude is approximately 250 ps (0.07 UI), depending
on the TG2000 output jitter.
17.
Enter Pass or Fail in the test record for SD Jitter Waveform Noise.
