Sorting According to Measurement Results
Overview of BIN Sort Function
Concept of setting 4287A BINs
Each BIN sorting condition based on the obtained measurements is set according to the
principles given below and illustrated inTable 8-1.
•
A maximum of 13 BINs can be set for each measurement point table (unused BINs are
turned off).
•
Bins are sequentially evaluated from BIN 1 to BIN 13. The first BIN meeting the
appropriate conditions is selected in sorting. For details, see "Internal flow of BIN sort
judgment" on page 176.
•
Each BIN can be assigned a maximum of four sorting conditions. Only the BINs
meeting all of these preset sorting conditions can be selected in sorting.
•
Four sorting conditions—measurement point (measurement point number),
measurement parameter, limit mode and reference value—are set as BIN range setting
conditions common to all BINs.
•
Settings for each BIN and for each sorting condition include the upper limit value,
lower limit value, and BIN range mode.
•
Even after sorting conditions have been set, each BIN can be turned on (active) or off
(inactive, where the BIN is assumed to be non-existent) if required. Furthermore, for
each BIN under each sorting condition, the condition setting can be turned on (active)
or off (inactive and regarded as meeting the conditions at all times).
•
Bins assigned given numbers (for example, BINs 6 to 13) can be specified as faulty
BINs. If a BIN is selected as faulty as a result of BIN sorting, its BIN number is output
to the handler interface together with the result of OUT_OF_GOOD_BINS.
•
If devices cannot be sorted to any of the preset BINs, only the result of
OUT_OF_GOOD_BINS is output and the BIN number is not output.
