Comparator Limit Mode
Functional Description
You can specify the primary parameter limit values in one of the following two
ways (see Figure 4-16):
•Tolerance mode
In tolerance mode, the comparison limit values are based on the deviations
from the specified nominal value, which can be specified in the NOM field.
You configure the tolerance mode limit values as a deviation percentage (%)
or absolute parameter value.
•Sequential mode
In sequential mode, the comparison limit values are based on the absolute
value of the measurement. When you configure these limit values, you have
to first define the minimum value and then the maximum value.
Figure 4-16 Tolerance mode and sequential mode
When you use tolerance mode, you have to assign the narrowest limit
value (range) to bin 1, the second narrowest range to bin2, and so on,
finally assigning the widest range to the last bin. Should the range
assigned to bin 1 be wider than those assigned to subsequent bins, all
DUTs would be sorted into bin 1.
In tolerance mode, the lower limit need not be smaller than the nominal
value, and the upper limit value need not be larger than the nominal value.
As you can see in Figure 4-17, as sorting occurs, there may be blanks or
overlaps.
