Count Field (State only)
The Count field is used to access a selection menu which is used to stamp the
acquisition data at each memory location with either a Time tag or a State
count tag.
Storing Time or State tags
If you have all pod pairs assigned, the state acquisition memory is reduced by
I
half, when time or state tags are turned on. You can maintain full memory
depth if you leave a specified pod pair unassigned.
States States count places numbered tags on
all
pretrigger and
posttrigger data. Data stored before trigger has negative numbers and
data stored after trigger has positive numbers. State tag numbering is set
to be either relative to the previous memory location or absolute from the
trigger point. Selecting the Absolute or Relative option is done by
toggling the Absolute/Relative field. When State count is selected in the
Trigger menu, the exact state locations tagged can be selectively chosen
from the Resource Term selection list.
