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.
