For the DATA instruction, block data consists of either 14506 bytes
containing logic analyzer only information or 26794 bytes containing both
logic analyzer and oscilloscope information. This information is captured
by the acquisition systems. The information for the logic analyzer will be
in one of four formats depending on the type of data captured. The logic
analyzer format is described in the "Acquisition Data Description" section
in "Logic Analyzer Block Data." The oscilloscope format is described in
the "Acquisition Data Description" section in "Oscilloscope Block Data."
Since no parameter checking is performed, out-of-range values could
cause instrument lockup; therefore, care should be taken when
transferring the data string into the HP 1652B/53B.
The < block data > parameter can be broken down into a
The <block length specifier > always takes the form #8DDDDDDDD.
Each D represents a digit (ASCII characters "0" through "9"). The value of
the eight digits represents the total length of the block (all sections). For
example, if the total length of the block is 14522 bytes, the block length
specifier would be "#800014522".
Each < section > consists of a <section header > and < section data > .
The < section data > format varies for each section and may be any
length. For this instruction, the < section data > section is composed of a
data preamble section and an acquisition data section.
