Component Digital Test Signal Generator

Model Details

4:2:2 Operates in both 525/60 and 625/50 systems Features EDH functions, conforming to SMPTE RS-165 Embedded, internally generated digital-audio test tones 4 serial outputs provided: 3 of the selected test signal with menu-selected EDH and embedded AES/EBU digital audio; fourth is a valuable digital black with menu-selected EDH A precision source of 10-bit 4:2:2 component digital test signals, the LT-425D offers features that make it an ideal choice for production and development applications. These include both embedded AES/EBU digital audio test tones and a dedicated rear panel AES/EBU output. Front panel switching includes 625/50 or 525/60 operation (test signals adapt automatically to suit the system selected) on/off control of Y, Cb and Cr. 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. Digital genlock includes front panel advance/delay keys (coarse and fine). The carse keys operate in 3 µs increments, the fine keys in increments of 20 ns. This combined with a ±16 line menu selected advance/delay yields precise, calibrated timing control. Rear panel facilities include a 4 serial outputs (one digital black), 1 parallel output, 1 AES/EBU digital XLR audio output, 2 black burst analog outputs, a pair of genlock loop-through inputs and a 27 MHz clock output.
