Markers Statistics; Accumulate Mode - HP 1652B Getting Started Manual

Also available is Store exception to disk which allows you to specify a
fde on the disk that exceptions can be stored in. The default fdename is
EXCEPTION.
The upper and lower range boundaries must not be the same value. For
example, if you want to stop a measurement when the X and 0 markers
are in range of 200 ns, you should set the range values to
190
ns and 210
ns. This eliminates erroneous measurement termination.
Markers Statistics
When statistics are specified for markers, the logic analyzer will display
the following:
l
Number of total runs.
l
Number of valid runs (runs where markers were able to be placed
on specified patterns).
l
Minimum time between the X and 0 markers.
l
Maximum time between the X and 0 markers.
l
Average time between the X and 0 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 (repetitive or single).
In repetitive, statistics will be updated each time a valid run occurs
until you press STOP. When you press RUN after STOP, the statistics
will be cleared and wiIl restart from zero.
In single, each time you press 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 0 markers between runs.
Accumulate Mode
Accumulate mode is selected by toggling the Accumulate ON/OFF
field in the Timing Waveforms menu. When accumulate is on, the
timing analyzer displays the data from a current acquisition on top of
the previously acquired data.
