SEQ sweep mode
：
/INDEX is defined as the effective signal when the last sweep point of the
analog test is finished.
/EOM is defined as the effective signal when all the test results are effective after
119
every list sweep task is finished.
STEP sweep mode
：
/INDEX is defined as the effective signal when the analog test of every sweep
point is finished.
/EOM is defined as the effective signal when the test and the comparison of every
step are finished.
The pin distribution for list sweep is shown in table 3 and figure 2. (The pin
definition for the list sweep comparison is the same to that for the BIN
comparison). The timing chart is shown in figure 5.

SEQ
：
when the analog test of the last sweep point is
finished and the UNKNOWN terminal can be connected
to another DUT, /INDEX is effective. But the
comparison signal is effective until /EOM is effective.
STEP
：
when the analog test at each sweep point is
finished, /INDEX is effective. But the comparison signal
30 /INDEX
is effective until /EOM is effective.

SEQ
：
when the test is finished and the compared
results are effective, this signal is effective.
