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.
2.
Press the DISPLAY SELECT 4 button.
3.
Press STATUS to display the status screen in tile 4.
4.
Press and hold STATUS to display the pop-up menu, and then select Video
Session.
5.
Connect a cable to the Normal output from the TG2000 DVG (not the Opt
S1 output). Typically the Normal output is the top BNC on the DVG1
module.
6.
Connect the other end of the cable to the Faraday Cable clone.
7.
Connect a second cable to the other port of the cable clone.
8.
Connect the other end of the second cable to either of the SDI Input A
connectors on the waveform rasterizer.
9.
Terminate the other SDI Input A connector.
10.
Set the cable clone for minimum cable length, that is, all switches to the
“out” position.
11.
On the TG2000 DVG1, set the output to the SDI Matrix signal.
12.
You should see a stable picture and waveform on the waveform rasterizer
display. All the EDH parameters on the Status screen should read Valid.
13.
Adjust the cable clone to find the longest length of “cable” that does not
generate any EDH errors in a 10 second period.
14.
Divide the length of Belden 8281 cable by 10 to calculate the attenuation in
dB at 135 MHz.
15.
Record the value in the test record.
16.
Repeat the test using SDI Input B on the waveform rasterizer.
17.
Record this level in the test record.
