Link Electronics HDG-821 High Definition Test Generator with Genlock

The HDG-821 gen-locks to an analog black burstsignal. The HDG-821 is a high definition video testpattern 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. Thedigital and analog outputs are simultaneous on therear panel, and contain the same test pattern. Aseparate tri-level-sync output is also provided. Thetri-level-sync output has the same data rate as thetest pattern being generated. The user may embedinternal audio tones on the digital video output ifdesired.

There are two audio groups supported, which willallow for eight channels. The channels can beenabled on an individual basis. The internal tonesgenerated are 400Hz and 1 KHz. There are also twoBNC connectors for AES output, which will allow forfour channels of audio for monitoring. Serial controlwill 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 audioamplitude is adjustable from 0 to -30dBFS andfrequency of 400 Hz to 10KHz.
