This digitally synthesized generator outputs a remarkable number of DTV formats
compliant with ISDB, ATSC and DVB standards. The DVI-D output conforms to DDWG
digital display working group standards supporting single link TMDS transition
minimized differential signaling up to 165 MHz clock rates. TMDS helps to reduce
EMI induced errors over today's long cables. Menu control of operating options
is facilitated with front panel keys and on-screen menus. These include embedded
audio channel on/off control and tone frequency selection. ID character and
calendar/clock programming, timing advance/delay to ± 16 lines, EDH on/off, key
lock and control of the moving target and switched pattern displays. The latter
are of value in compression testing and controls effect the speed and direction
of the moving target and the dwell intervals for sequential switching of
selected test patterns. |
