GPIB reading speed comparisons
The tables that follow compare the differences in reading speed for the SCPI and 488.1
protocols. Included in all tables is the percentage improvement achieved with the 488.1
protocol compared to the SCPI protocol. The most significant speed improvements are
shown in the shaded areas of the tables.
Sweep operation
Table G-1 through Table G-4 show bus reading rates for measure-only, source-measure,
source-measure-limit test, and source-memory sweep operation respectively. Note that the
reading rate for sweep operation can be increased by almost 50%.
