10 bytes - Number of rows of valid data for this analyzer - Indicates the
number of rows of valid data for each of the five pods. Two bytes are used
to store each pod value, with the first 2 bytes used to hold POD 5 value,
the next 2 for POD 4 value, and so on.
1 byte - Trace point seen in this analyzer - Was a trace point seen (value
= 1) or forced (value = 0)
1 byte - Reserved
10 bytes - Trace point location for this analyzer - Indicates the row
number in which the trace point was found for each of the five pods. Two
bytes are used to store each pod value, with the first 2 bytes used to hold
POD 5 value, the next 2 for POD 4 value, and so on.
4 bytes - Time from arm to trigger for this analyzer - The number of 40 ns
ticks that have taken place from the arm of this machine to the trigger of
this machine. A value of -1 (all 32 bits set to 1) indicates counter overflow.
1 byte - Armer of this analyzer - Indicates what armed this analyzer (1 =
RUN, 2 = BNC, 3 = other analyzer)
1 byte - Devices armed by this analyzer - Bitmap of devices armed by this
machine

A 1 in a given bit position implies that this analyzer arms that device,
while a 0 means the device is not armed by this analyzer.
4 bytes - Sample period for this analyzer (timing only) - Sample period at
which data was acquired. Value represents the number of nanoseconds
between samples.
4 bytes - Delay for this analyzer (timing only) - Delay at which data was
acquired. Value represents the amount of delay in nanoseconds.
1 byte - Time tags on (state with tagging only) - In state tagging mode, was
the data captured with time tags (value = 1) or state tags (value = 0).
