摘要： One or more recently acquired waveform data sets are maintained in memory after they are initially rasterized. During repeated waveform acquisitions, when the trigger and new waveform acquisition rates become so low that rasterizer time is being wasted, one or more of the most recent previously acquired waveforms are re-rasterized and displayed again to maintain the display until another newly acquired waveform becomes available. The rasterizer's readiness to re-rasterize a previously rasterized waveform data set can be qualified with a pre-determined or programmable time delay, thereby providing more flexibility for external circuitry and controllers to optimize utilization of the rasterizer's behavior. The method of this invention works especially well with rasterizers that produce some form of randomization in their outputs.
