Ti me I nt er val The X and O markers measure the time interval between a point on a Ti me I nt er val
timing waveform and the trigger, two points on the same timing waveform, two points on
different waveforms, or two states ( time tagging on) .
Del t a St at es ( st at e anal yzer onl y) Del t a St at es ( st at e anal yzer onl y) The X and O markers measure the number of
tagged states between one state and trigger or between two states.
Pat t er ns The X and O markers can be used to locate the nth occurrence of a specified Pat t er ns
pattern from trigger, or from the beginning of data. The O marker can also find the nth
occurrence of a pattern from the X marker.
St at i st i cs St at i st i cs X and O marker statistics are calculated for repetitive acquisitions. Patterns
must be specified for both markers, and statistics are kept only when both patterns can
be found in an acquisition. Statistics are minimum X to O time, maximum X to O time,
average X to O time, and ratio of valid runs to total runs.
