<p>A display memory (50) and controller (61) for displaying waveforms and vectors on raster-scanned conventional video monitors so that the display appears the same as oscilloscope or monitor displays. The brightness of any spot is set by the number of times that an input signal is at the same position on repetitive equivalent sweeps. As the signal passes a time and voltage point, the memory (50) is read to determine the brightness level from before, and a new level is written in to approximate the intensity function of CRT phosphor. As the memory (50) is displayed, the values are decreased to approximate the decay of a CRT phosphor. A memory controller allows the signal to be directly input to memory for later processing for fault determination.</p> |
