3. The external waveform monitor (WFM700) displays the following observation:
a. Colorbar video pattern
b. Video format detected is 1080i 60.00
c. Embedded audio standard detected is SMPTE299M
d. Audio channel pairs (1,2), (3,4), (5,6) and (7,8) are present
Transmit 3G-SDI Level A with Embedding of Audio Group 1, 2 and 3
To transmit the 3G-SDI Level A video standard, follow these steps:
1. Set DIP switch[2:1] = 11
2. The demonstration runs and the LEDs indicate the following conditions:
a. LEDs D6 and D7 indicate the internal video pattern generator signal standard.
b. LEDs D8 and D9 indicate the receive video standard.
c. LED D16 blinks indicating the heartbeat of the receiver's recovered clock..
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. LEDs D23, D22 and D21 illuminate when the data packet of audio groups 1, 2 and 3 are detected in
the incoming SDI stream.
This figure shows the condition of the LEDs.
