Differences in usage of GPIB commands
Sorting target Can be set up independently of the
parameter measurement parameter.
You cannot turn ON/OFF each BIN
separately. Sorting targets are all of the
BINs for which the limit range has been set
ON/OFF of BIN up. Therefore, to exclude BINs that have
been set up from sorting targets, you need
to clear all the limit ranges and set them
again.
You use a single command to set up the
limit ranges for all BINs (sequential mode).
Setting limit ranges
The limit ranges of each BIN must be
in absolute values
continuous.
Executing the limit value setup command
(the boundary value to detect Low C) turns
ON/OFF of Low C
ON the Low C reject function.

UNVAL: Counts into OUT_OF_BINS.

4278A
Depends on the measurement parameter
and cannot be set up independently.
You can turn ON/OFF each BIN separately.
Sorting targets are the BINs set to ON only.
Therefore, when setting up BINs, you need
to set up the limit range for each BIN and
then turn it ON.
You use several commands to set up the
limit range for each BIN separately
(absolute mode). The limit range of each
BIN does not have to be continuous (that is,
gaps are allowed).
Executing the limit value setup command
does not turn ON the Low C reject function
automatically. Therefore, you need to set
up the limit value and then turn ON the
Low C reject function.
Sorts into suitable BIN according to
measurement results. (The 4288A does not
have a BIN reserved for only Low C.)
OVLD: Counts into OVLD.
Low C: Counts into a suitable BIN
according to measurement results.
