Electrical features
As shown in the previous section, the signal assignment and functions of most pins are different
for the comparison and the list sweep comparison. However, the electrical features are the
same. Therefore, the following description can be applied to BIN comparison and List Sweep
comparison.
There is DC isolation on the output on pins 1 to pin 16 generated by a collector-open
optoelectronic coupler. The output voltage on every line is set by the pull-up resistance on the
HANDLER interface board. The pull-up resistance is connected to the internal voltage (+5V), or
the external voltage (EXTV: +5V).
The electrical features of the DC isolation output can be divided into 2 types shown in the table
below:
