Markers Statistics When statistics are specified for markers, the logic analyzer displays:
• Number of total runs
• Number of valid runs (runs where markers were able to be placed on
specified patterns)
• Minimum time between the X and O markers
• Maximum time between the X and O markers
• Average time between the X and O markers
Statistics are based on the time between markers which are placed on
specific patterns. If a marker pattern is not specified, the marker will be
placed on the trigger point by the logic analyzer. In this case, the statistical
measurement will be the time from the trigger to the specified marker.
How the statistics will be updated depends on the timing trace mode
(single or repetitive).
In repetitive, statistics will be updated each time a valid run occurs until
you press Stop. When you touch Run after Stop, the statistics will be
cleared and will restart from zero.
In single, each time you touch Run an additional valid run will be added to
the data and the statistics will be updated. This will continue unless you
change the placement of the X and O markers between runs.
Accumulate Mode Accumulate mode is selected by toggling the Accumulate On/Off field.
When accumulate is on, the timing analyzer displays the data from a
current acquisition on top of the previously acquired data.
When the old data is cleared depends on whether the trace mode is in
single or repetitive. In single, new data will be displayed on top of the old
each time Run is selected as long you stay in the Timing Waveforms menu
between runs. Leaving the Timing Waveforms menu always clears the
accumulated data. In repetitive mode, data is cleared from the screen only
when you start a run after stopping acquisition with the Stop key or when
changing menus.
