Signal Line Definitions for the List Sweep Comparator
The signal definitions for the list sweep comparator differ from those for the
comparator.
When the handler interface is used with the list sweep comparator, the
following signal definitions apply:
— Test result output signals
Signals /BIN1 to /BIN9 and /AUX_BIN represent the results of IN/OUT tests
at sweep points 1 to 10, respectively. /OUT_OF_BINS indicates whether the
DUT has passed or failed the test (a DUT fails the test if it generates an OUT
result in any of steps 1 to 201 during one cycle of sweep measurement).
These signals are output at the end of the sweep cycle.
— Control output signals
The output timings of /INDEX (“end of analog measurement”) and /EOM
(“end of measurement cycle”) signals differ depending on the sweep mode
for list sweep (these signals behave differently than when used for the
comparator).
1. SEQ sweep mode
/INDEX is output when the last analog measurement in the sweep
cycle is complete. /EOM is output when all the comparator test
results become available after the end of the sweep cycle.
2. STEP sweep mode
/INDEX is output when the analog measurement step in each step of
the sweep cycle is complete. /EOM is output when the all the
measurements in each step of the sweep cycle are complete
(including the measurement time).
Connector pin layouts and comparator signal descriptions for the list sweep
comparator are shown in Table E-13, Figure E-4, and Figure E-2. (the pin
layouts for the list sweep comparator are the same as those for the
comparator). Also,
Figure E-5 shows a signal timing chart.
A signal prefixed with a slash (/) indicates that the signal is negative logic
(active low).
