The HDG-821 gen-locks to an analog black burst signal. The HDG-821 is a high definition video test pattern generator in a standalone one rack (RU)chassis. The unit has two serial digital HD outputs at1.485 Gb/s and YUV/RGB analog outputs. The digital and analog outputs are simultaneous on there are panel, and contain the same test pattern. A separate tri-level-sync output is also provided. The tri-level-sync output has the same data rate as the test pattern being generated. The user may embed internal audio tones on the digital video output if desired.
There are two audio groups supported, which will allow for eight channels. The channels can been able on an individual basis. The internal tones generated are 400Hz and 1 KHz. There are also two BNC connectors for AES output, which will allow for four channels of audio for monitoring. Serial control will allow changes to be made via a PC.
The are a total of thirty test signals available,including SMPTE, EIA and full field bars. AES audio amplitude is adjustable from 0 to -30dBFS and frequency of 400 Hz to 10KHz.
