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
/BIN1 to /BIN9, /AUX_BIN, /OUT_OF_BINS, /PHI (“primary parameter
beyond upper limit” signal), /PLO (“primary parameter below lower limit”
signal), /SREJ (“secondary parameter out of limits” signal), /OVLD
(measurement failure” signal)
— Control output signals
/INDEX (“end of analog measurement” signal), /EOM (“end of measurement
cycle” and “result data available” signal), /READY_FOR_TRIGGER (“ready
for trigger” signal)
— Control input signals
/EXT_TRIG (“external trigger” signal), /KEY_LOCK (“key lock” signal)
Connector pin layouts and comparator signal descriptions are shown in Table
E-13
, Figure E-1, and Figure E-2. Also, Figure E-3 shows a signal timing chart.
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.
