G-6
GPIB 488.1 Protocol
GPIB reading speed comparisons
The tables that follow compare the differences in reading speed for the SCPI and 488.1 pro-
tocols. Included in all tables is the percentage improvement achieved with the 488.1 protocol
compared to the SCPI protocol. The most signi
fi
cant speed improvements are shown in the
shaded areas of the tables.
Sweep operation
Tables G-1 through 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%.
