Two firms reduce the cost of adding color to DS0 displays. (Gould's Datasys 700 and Tektronix Inc.'s TDS 544A and 644A oscilloscopes) (Product Announcement)

EDN, April, 1993 by Strassberg, Dan

Scopes with color displays offer obvious advantages, but until now, those advantages commanded a high price. When you view several waveforms at once, color makes them easy to tell apart. Depending on how a scope implements color, a multihued display can supply information that is missing from most monochrome DSOs' raster displays, but is inherently present in an analog scope's gray scale. A color scope can also ease the task of telling when two waveforms do and don't coincide. In the past, the problem with color-display scopes was that most were expensive; some cost well over $30,000; others cost close to $60,000. Now however, Gould and Tektronix have altered the cost picture for scopes with color displays.

Thanks to new technology, both firms are...
