3. The external waveform monitor (WFM700) displays the following observation:

a. Colorbar video pattern

b. Video format detect is 625i 50.00

c. Embedded audio standard detected is SMPTE272M

d. Audio channel pairs (1,2) and (3,4) are present

Transmit HD-SDI with Embedding of Audio Group 1 and 2

To transmit the HD-SDI video standard, follow these steps:

1. Set DIP switch[2:1] = 01

2. The demonstration runs and the LEDs indicate the following conditions:

a. LED D6 and D7 indicate the internal video pattern generator signal standard.

b. LED D8 and D9 indicate the receive video standard.

c. LED D16 blinks indicating the heartbeat of the receiver's recovered clock. The

frequency is blinking is slower than the previous demonstration.

d. LED D17 illuminates when the receiver is frame locked.

e. LED D18 illuminates when the receiver is TRS locked.

f. LED D19 illuminates when the receiver is alignment locked.

g. LED D23 and D22 illuminate when the data packet of audio groups 1 and 2 are

detected in the incoming SDI stream.

Figure 4–12

shows the condition of the LEDs.

3. The external waveform monitor (WFM700) displays the following observation:
