System Commands
The section header uses bytes 1 through 16 (this manual begins counting
at 1; there is no byte 0). The 16 bytes of the section header are as follows:
1 10 bytes - section name, such as
1 byte - reserved
1 bytes - module ID (31 for HP 1650B/51B)
4 bytes - length (always 14506 for HP 1650B/51B)
For the SYSTem:DATA command, the -z section data > parameter
consists of two parts: the data preamble and the acquisition data. These
are described in the following two sections.
The block data is organized as 160 bytes of preamble information,
followed by 1024 lrlbyte groups of information, followed by 10 reserved
bytes. The preamble gives information for each analyzer describing the
amount and type of data captured, where the trace point occurred in the
data, which pods are assigned to which analyzer, and other information.
Each 1Cbyte group is made up of two bytes (16 bits) of status for
Analyzer 1, two bytes of status for Analyzer 2, then five sets of two bytes of
information for each of the five 16-bit pods of the HP 16510B.
One analyzer's information is independent of the other
analyzer's information. In other words, on any given fine, one analyzer may
contain data information for a timing machine, while the other analyzer
may contain count information for a state machine with time tags enabled.
The status bytes for each analyzer describe what the information for that
line contains. Therefore, when describing the different formats that data
may contain below, keep in mind that this format pertains only to those
pods that are assigned to the analyzer of the specified type. The other
analyzer's data is TOTALLY independent and conforms to its own format.
