6.3.2 Generating HD Color Bar Patterns and Reclocking the Data Three Times

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

2. Connect a BNC cable between OUTC1 and IND1, a cable between OUTD1 and INB1, a cable between OUTB1 and INA1,

and a cable from OUTA1 to WFM 700. The pattern is sent from the FPGA to channel C; the data is then reclocked from channel

C to channel D, then reclocked from channel D to channel B, then reclocked from channel B to channel A and then displayed

on the WFM. Since HD color bars are transmitted, the primary outputs/inputs of each channel should be used.

3. For all channels, configure the clock headers to the programmable clock option.

4. Open the GUI.

5. Select appropriate buttons on the GUI according to Figure 6-6. Please note that there are two methods for setting the data

rate on the reclocker channels. One method is to select “Auto Rate Detect”, which will reconfigure the programmable clocks

to the incoming data rate. The other method is to set the data rate for all reclocked channels to be the same as the data rate

of the transmitting channel. In the set up shown in Figure 6-5 and Figure 6-6, the transmitting data rate is 1485 Mb/s which is

transmitting HD color bars. All reclocked channels are configured to automatically detect this data rate.

6. Press the “Run” button for channel C, then channel A, then channel B, then channel D.

7. View the picture display of the signal on the WFM 700.
