20090261814 | DRAWING WAVEFORMS IN NO DEAD TIME ACQUISITION SYSTEM - A method of drawing a waveform image in a no dead time acquisition system, where consecutive drawing frames overlap, uses a master/slave relationship between two fast rasterizers. The master rasterizer draws a first display frame in response to a first trigger event in a trigger signal derived from an input signal. The slave rasterizer draws a second display frame in response to a subsequent trigger event in the trigger signal. The portion of the second display frame that duplicates data contained in the first display frame is either (a) suppressed when the first and second display frames are combined to form the waveform image or (b) displayed in a different shade/color. Alternatively the first display frame may be compressed by 50% to form a first portion of the waveform image and the non-duplicative portion of the second display frame is compressed by 50% to form a second portion of the waveform image, the first and second portions being drawn contiguously when the first and second display frames are combined to form the waveform image. | 10-22-2009 |
