SPA Time Interval Menu
For measurement purposes, the analyzer measures the time between
the first occurrence of the Start condition and the first occurrence of
the Stop condition.
Defining the Time Interval ranges. Before changing the ranges
from their default values, you may want to press Run and acquire some
data. From this initial run, the Maximum (Max), Minimum (Min), and
Average (Avg) statistics on the display will help you choose the
appropriate set of Time Interval ranges.
To define the ranges, select the fields for the lower and upper limits
and enter the limits of the range. The ranges do not need to be
contiguous, but if you leave gaps between the ranges, critical data may
be missed. Also, if you overlap ranges, data may be counted multiple
times and present a misleading histogram.
