7  Sorting Based on Measured Results (Comparator 
Function)
This chapter describes how to use the function that performs sorting based on 
the measured results (comparator function).
Overview of Comparator Function
The E4981A’s comparator function lets you set up to 9 limit ranges for the 
primary parameter (BIN1 to BIN9) and 1 limit range for the secondary 
parameter and sort DUTs into up to 11 categories: BIN1 to BIN9, 
OUT_OF_BINS or AUX_BIN. If you need only simple pass/fail judgment and do 
not need BIN sorting, use the comparator function while setting up only 1 limit 
range for the primary parameter (BIN1) (and, if necessary, 1 limit range for the 
secondary parameter) to judge whether the measured result of the DUT falls 
into the specified limit range.
You can specify the upper and lower limit values for the primary parameter 
with not only absolute values but also relative values (deviation) from the 
reference value (nominal value).
The sorting judgment result of the comparator function is displayed on the 
screen and also output from the handler interface. In addition, you can read 
out the sorting judgment result from an external controller by using the SCPI 
command together with the measured value.
You can use the BIN count function to count the number of DUTs sorted into 
each BIN, display the counts on the screen, and read them out with the SCPI 
command.
