Model LT 441D meets the SDI test signal needs for fourteen formats based on 720, 1035 and 1080 lines displayed. These include the newer formats that employ variations of the 24 sF systems. Three SDI outputs are provided plus analog tri-level sync, H and V drive. Features include eight channels of embedded AES/EBU digital audio for the most popular formats. Six channels of AES/EBU digital audio are supplied separately in signal pairs on three BNC connectors. Digital genlock locks to tri-level sync from HDTV reference or black burst from 525 line timing references. Provision is made for selectable advance/delay to ±100 lines.Two clock references accommodate 60/30 and 59.94/29.97 and other frame rates. Colorimetry (Y formulation) is selected automatically to match the system selected. The generator also supports applicable error-detection systems.Test signals include a new 16 x 9 monoscope pattern, the pathological check field, and two dynamic systems to provide the means to check the effects of concatenated compression. These employ a moving target whose direction and speed may be controlled and a menu controlled sequence of selected test patterns with controlled dwell times. A 20-character programmable source ID is also provided.
