WVR6100, WVR7000, and WVR7100 Specifications and Performance Verification

This test uses a cable clone to simulate cable. This verifies that the waveform
rasterizer can receive signals that have passed through long cables.

1.

Press FACTORY, and then press the DISPLAY SELECT 4 button.

2.

Press STATUS to display the status screen in tile 4.

3.

Press and hold STATUS to display the pop-up menu, and then select Video
Session. Press STATUS again to remove the pop-up menu.

4.

Connect a cable to an output from 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 the other end of the second cable to either of the SDI Input A
connectors on the waveform rasterizer.

8.

Terminate the other SDI Input A connector.

9.

On the TG2000 HDVG1, set the output to the SDI Matrix signal.

10.

You should see a stable picture and waveform on the waveform rasterizer
display. All the CRC parameters on the Status screen should read Valid.

11.

Connect additional sections of the HD Cable Clone into the signal path to
find the longest length of “cable” that does not generate any CRC errors in a
10 second period.

12.

Add the HD Cable Clone section lengths to get the total length in meters of
Belden 8281 cable. Divide by 4 to calculate the attenuation in dB at
750 MHz.

13.

Record the value in the test record.

14.

Repeat the test using SDI Input B on the waveform rasterizer.

15.

Record this level in the test record.
