IntroductionThe DATA and SETup commands are SYSTem commands that allowyou to send and receive block data between the HP 16554A,HP 16555A, or HP 16555D

Data FormatTo understand the format of the data within the block data, there are fourimportant things to keep in mind.•Data is sent to the controller
