Video Signal Generator

Video Signal Generator

A video signal generator, as the name implies, is a specialized signal generator that outputs video signals for troubleshooting, testing, and synchronization of television and video systems. 

Basic Selection Criteria for Video Signal Generators

• Function of the Video Signal Generator
  • est Signals or Patterns are generated  for troubleshooting and analyzing television systems
  • Sync Pulse Generators output master synchronization signals for production, post production, component and systems maintenance and the engineering lab. Analog signals would contain horizontal and vertical sync pulses and colorburst sync signals for NTSC and PAL composite video signals
• Video Formats and Interface Standards supported by the Video Signal Generator
• Expandable/Configurable Video Signal Generators
• Some models have a rack mount mainframe with various plug-in modules to enable the output of signals (i.e. HDTV, SDTV, DV-I), sync signals, and analog signals. With these signals and genlock functions, timing is settable in increments of frames, lines, pixels or clock intervals. Generate monoscope, color bar, ramp, crosshatch, multiburst, character, and other test patterns. Users can customize the signal generator as desired
• Lower cost pocket /handheld size video generators
