7.2.1.2 Signal Line Used for List Sweep Comparator Function
Signal definition used for the list sweep comparator function is different from that used
for the comparator function. Signal definition used for the list sweep comparator
function is as follows.
 Comparison Output Signals:
/BIN1-BIN3 and /OUT indicate IN/OUT judgments for each sweep point (refer to
Figure 7-4). /AUX indicates pass/fail judgment (one or more failed judgments of
steps 1 to 4 occurred during a single sweep).
These signals are output when the sweep measurement is completed.
 Control Output Signals:
/IDX (analog measurement completed signal) and /EOM (end of measurement
signal). The timing when /IDX and /EOM are asserted is as follows: (different
from that used for the comparator function).
In the SEQ sweep mode:
/IDX is asserted when the last step of an analog measurement of a sweep
