Byte Position
26 1 byte - Master chip for this analyzer. This decimal value returns which
chip’s time tag data is valid in a non-transitional mode; for example, state
with time tags.
5 - pods 1 and 2 2 - pods 7 and 83
4 - pods 3 and 411 - unused
3 - pods 5 and 620 - unused
– 1 - no chip
1 – also unused in the 1663A
2 – also unused in the 1662A and 1663A
3 – also unused in the 1661A, 1662A, and 1663A
27 6 bytes - Unused
33 8 bytes - A decimal integer representing sample period in picoseconds
(timing only).
Example The following 64 bits in binary would equal 8,000 picoseconds or, 8
nanoseconds:
00000000 00000000 00000000 00000000 00000000 00000000 00011111 01000000
41 8 bytes - Unused
49 1 byte - Tag type for state only in one of the following decimal values:
0 = off
1 = time tags
2 = state tags
50 1 byte - Unused
51 8 bytes - A decimal integer representing the time offset in picoseconds from
when this analyzer is triggered and when this analyzer provides an output
trigger to the IMB or port out. The value for one analyzer is always zero and
the value for the other analyzer is the time between the triggers of the two
analyzers.
59 2 bytes - Unused
