The Analyzer Trigger Menu

Count field (State only)

The Count field accesses a selection menu which indicates whether

acquisition data is stamped with a Time tag or a State Count tag.

If you have all pod pairs assigned, the state acquisition memory is

reduced by 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 places numbered tags on all data relative to the trigger.

Pre-trigger data has negative numbers and post-trigger data has

positive. In the display menus, State numbering is either relative to the

previous memory location or absolute from the trigger point. You can

set it in the display menus by toggling the Absolute/Relative field.

Time. Count time places time tags on all displayed data. Data stored

before triggering has negative time numbers and data stored after

triggering has positive time numbers. Time 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. Time tag resolution is 8 ns.

To retain full memory using time or state tags. To retain full

memory depth when using time or state tags requires that one pod pair

be unassigned. The exact pair to unassign varies. Generally, it is best to

unassign one of the middle pod pairs. If you have two analyzers

configured, the ends must be assigned to different analyzers.
