Handler Interface

Signal Line Definitions

Signal Line Definitions
The instrument uses three types of signals: test result output, control output,
and control input. The definitions of test result output and control input signals
differ depending on whether they are used for the comparator or the list sweep
comparator.
This section explains the signal definitions that apply when using the handler
interface with the comparator and with the list sweep comparator.

Signal Line Definitions for the Comparator

When the handler interface is used with the comparator, the following signal
definitions apply:
— Test result output signals
— Control output signals
— Control input signals
Connector pin layouts and comparator signal descriptions are shown in
E-13,
A signal prefixed with a slash (/) indicates that the signal is negative logic
(active low).

Output These signals indicate the result of sorting. They show into which bin the DUT has
been sorted. 
All of these output signals are open-collector based.
