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
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
bit 7 bit 6 bit bit 4 bit 3

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).
