A digital oscilloscope in which the acquisition/data accumulation is decoupled from the display of the accumulated date in order to increase the speed at which new data may be accumulated and displayed. The invention also provides for variable persistence in the accumulated data so that the displayed image shows the changes in the sampled event over time. The decay, however, is proportional to population for each amplitude/time combination in the data. This maintains the statistical integrity of the data. Further, the data from each channel is assigned a different color and different populations within the channel's data is assigned a different shade of the color. These shades are dynamically updated as data from new acquisitions are accumulated. In order to highlight the population distribution in the rare events, population saturation levels may be specified. <IMAGE> |
