Synchronized waveform outputs for use in wipe and pattern generation
Video Ramps is a dual synchronized waveform generator. One ramp generator is locked to the vertical interval of the video display (Field-rate sync), and the other is locked to the horizontal interval (Line-rate sync). Four different output waveforms are available from each ramp generator, including sawtooth, inverted sawtooth, triangle, and inverted triangle. Video Ramps offers a minimal solution to augment your system’s available waveform generation capabilities (such as Video Waveform Generator modules), with outputs that are useful in almost any wipe or shape generation application. Additionally, the outputs can be used to sweep the X & Y inputs of an oscilloscope or vector display for vector rescanning experimentation. Video Ramps requires internal connection to a Video Sync Generator module via the special provided 14-pin IDC cable in order to function.
Video Ramps includes a 14-Pin Video Sync Expansion Cable, which must be connected to the existing Video Sync chain coming from the Video Sync Generator module in an LZX Visionary system. Below is the process for connecting the expansion cable. Connection to the power distribution bus is the same as normal, and described on the Module Installation page.
Step 1. Remove your Color Video Encoder and Video Sync Generator modules and place them next to your new Video Ramps. Detach the short 14-pin Video Sync Cable from Color Video Encoder.
Step 2. Connect the disconnected end of the short 14-pin Video Sync Cable to the male header on the 14-pin Video Sync Expander Cable.
Step 3. Connect the first female header on the 14-pin Video Sync Expander Cable to the Color Video Encoder as shown.
Step 4. Connect the final female header on the 14-pin Video Sync Expander Cable to Video Ramps as shown.
