6.3.3 Using Redundant Outputs

This test shows that primary input/output of a channel on the board supports both SD-SDI and HD-SDI standards while the

secondary input/output supports only the SD-SDI standard (due to presence of SD-SDI equalizers and cable drivers on secondary

I/Os).

1. Apply power to the board and connect the USB cable between the board and the computer.

2. Connect output OUTB1 to the WFM 700 channel A input and connect output OUTB2 to the WFM 700 channel B input using

BNC cables.

3. Open the GUI.

4. Select the appropriate GUI settings according to Figure 6-8. For this setting, channel B is transmitting SD-SDI color bars on

both primary and secondary outputs.

5. Press the “Run” button for channel B.

6. Press the “Input” button on the WFM to display either the primary or secondary output.

7. Press the “Stop” button for channel B.

8. Change the GUI settings according to Figure 6-9. For this setting, channel B is transmitting HD-SDI color bars only on the

primary output.

9. Press the “Run” button for channel B.

10.Press the Input button on the WFM 700 to display either the primary or secondary output. No signal is shown when the

secondary output is selected.
