Method of controlling a sparse vector rasterizer

摘要

A signal acquisition instrument acquires a succession of waveform records and sequentially transfers the waveform records to a rasterizer for rasterizing the waveform records to generate respective rasterized records each composed of a set of vectors, but inhibits transfer of a current waveform record to the rasterizer until a previous waveform record has been rasterized. The maximum number of dots (M) in each vector is made as large as possible provided that the rasterizer does not complete rasterization of the previous waveform record after acquisition of the current waveform record is complete.
