DATA
System Commands
6-6
For the DATA instruction, block data consists of 14506 bytes containing
information captured by the acquisition chips. The information will be in
one of four formats, depending on the type of data captured. Each format
is described in the “Acquisition Data Description” section. 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
1650B/51B.
The
(block
data
>
parameter can be broken down into a
<
block length specifier > and a variable number of
c
section
>
s.
The c 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 c section data > .
The
-z
section data
>
format varies for each section and may be any
length. For this instruction, it is composed of a data preamble section and
an acquisition data section.
