WFM5200 Waveform Monitor Specifications and Performance Verification
waveform monitor that has 3 Gb/s CRC check capability. Input 1A should
be selected.
19. A 4-tile display consisting of waveform, video session status, picture, and
audio level bars should appear. Check that:
a. The waveform display shows a stable YPbPr parade, with all three
components present and each being 700 mVp-p.
b. The Video Session screen indicates "OK" for CRC errors.
c. A full field color bar waveform appears in the Picture display.
d. Audio bars appear for Channels 1-4 (nominally at –20 dBFS), if the audio
option is present.
e. The lower left corner readout indicates "1080p 59.94".
20. On the second waveform monitor, check that a color bar signal is being
received and that no CRC errors are present.
21. Record Pass or Fail for SDI 1A, 3Gb/s in the test record.
22. Repeat steps 19 and 20 above for the SDI 1B input. Record Pass or Fail
for SDI 1B, 3 Gb/s in the test record.
23. Repeat this entire procedure for SDI Input 2A and SDI Input 2B.
Waveform Signal Path Stuck Bit Test.
1. Connect a 1.5 Gb/s 1080i 59.94 10-bit shallow ramp matrix signal from the
HDVG7 module to the SDI 1A input of the instrument under test. (The
shallow ramp matrix signal can be found under the LINEARITY button).
2. Set the waveform monitor to Factory Presets. (See page 32, Restore the
Factory Presets.) A YPbPr parade should be displayed in Tile 1.
3. Turn off the Pb waveform:
a. Press and hold the WFM button to display the waveform menu.
b. Select Pb.
c. Use the SEL button to select Off.
d. Press the WFM button to close the menu.
4. Press and hold the Display Select button to expand the waveform tile to full
screen.
5. Inspect the Y and Pr waveforms. Each should contain a series of equally
spaced shallow ramps. Each ramp should increase monotonically. Stuck
