measurement is completed. /EOM is asserted when all of the comparison results
are valid after a sweep measurement.
In the STEP sweep mode:
/IDX is asserted after each step of analog measurement in a seep measurement
is completed. /EOM is asserted after each step measurement, inclding
comparison time, is completed.
The contact assignments and a brief description of signals used for the list sweep
function are given in Table 7-3 and Figure 7-2 (pin assignments for the list sweep
comparator function are the same as for the comparator function). The timing
diagram is shown in Figure 7-5.
The /(back slash) in the signal name means that the signal is asserted when LOW.

11 /AUX
/AUX is asserted when one or more file judgments of Steps 1
to 10 occur in a single sweep.
12-18 Same as the assignments for the comparator function (Refer
to Table 7-2).
19-21 N.U Not Used (Off state, HIGH level)
22-29 Same as the assignments for the comparator function (Refer
to Table 7-2).
30 /IDX In the SEQ sweep mode:
/IDX is asserted when an analog measurement of the last
sweep step is completed, and TH2816B is ready for the next
DUT to be connected to the UNKNOWN terminals. The
measurement data, however, is not valid until/EOM is
asserted. (See Figure 7-5)
In the STEP sweep mode:
/IDX is asserted when each analog measurement is complete
and TH2816B is ready for the next sweep step. The
measurement data, however, is not valid until /EOM is
asserted (See Figure 7-5).
31 /EOM End of Measurement
In the SET sweep mode :
/EOM is asserted when the measurement data and
comparison results are valid after the last step measurement
is completed. (See Figure 7-5.)
In the STEP sweep mode:
/EOM is asserted when each step measurement, including the
comparison times, is completed and the measurement data is
valid. The comparison results are valid after the /EOM signal
of the last sweep point is asserted. (See figure 7-5)
32-36 Same as the assignments for the comparator function (Refer
to Table 7-2).
