Lower and Upper Limits

Functional Description
The E4980A/AL's built-in comparator can sort DUTs into a maximum 10 levels
(bin 1 through bin 9 and OUT OF BINS) using up to nine sets of primary
parameter limits along with one set of secondary parameter limits. Use the
LOW/HIGH field for each of bins 1 through 9 to define the primary parameter
lower and upper limits and the 2nd LOW/HIGH field to define the secondary
parameter lower and upper limits.
When the comparator limit is set to tolerance mode, you have to set the lower
limit to a value lower than the upper limit. If the lower limit is higher than the
upper limit, a "Warning, Improper high/low limits" warning message appears. If
you proceed without correcting the lower and upper limits, that bin's result is
null and the comparator continues to the next bin to perform bin sorting.
When the comparator limit is set to 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. If this rule is not followed, a "Warning, Improper
high/low limits" warning message appears. If you proceed without correcting
the lower and upper limits, that bin's result is null and the comparator
continues to the next bin to perform bin sorting.
In sequential mode, you can omit the lower or upper limit or both for bin 1, as
shown in the following examples:
•
•
144
Bin 1: lower limit (L1) only
Bin 2: upper limit (H2)
Bin 3: upper limit (H3)
Bin 1: upper limit (H1) only
Bin 2: upper limit (H2)
