SDI serial output amplitude
WVR8200 and WVR8300 Specifications and Performance Verification
10. Record the value in the test record. Acceptable performance is 20 dB or
greater.
11. Starting from step 3, repeat the test for the SDI B input (Front Panel Input
1B).
12. Option 2SDI only: Repeat this procedure for the Slot 2 SDI A (front panel
Input 2A) and SDI B (front panel Input 2B) inputs starting at step 3.
This completes the SDI Input Equalization Range checks.
This test verifies that the Serial Output signal amplitudes are within specifications.
All instruments have an SDI OUT signal output on the mainframe rear panel.
The content of this signal is determined by the Config> Outputs> SDI Output
setting. In addition, each SDI interface card provides two serial outputs. All
three serial outputs should be checked for proper amplitude. If this intrument is
installed with Option 2SDI, check all five outputs.
Mainframe serial output check (all models).
1. Set the waveform rasterizer to the Factory Preset.
2. Connect the TG700 or TG8000 DVG7 SIGNAL 1 output to the Slot 1 SDI A
input on the waveform rasterizer.
3. Set the DVG7 to provide a 525 270 Mb/s 100% color bar signal.
4. Input 1A should be selected on the waveform rasterizer. You should see a
stable color bar picture and waveform display.
5. Install the TCA75 adapter in the test oscilloscope CH 1 input. Connect the
waveform rasterizer mainframe SDI OUT to the oscilloscope CH 1 input.
6. Set the test oscilloscope as follows:
