Chapter 9 The description for Handler (optional)
This chapter will show you the Handler interface On ST2826.
The ST2826 provides the Handler interface for you. The interface is mainly used for the
output of the sorted result. The interface offers the communication signal and the signal for the
output of the sorted result. The separator result is corresponding to the output of BIN 10. The
design for the Handler interface is very smart with the status of the output signal can be
defined according to your application target
.
9.1The technology description for ST2826 Handler
Table 9-1 shows the description for ST2826 HANDLER.
Table 9-1 the HANDLER description
The output signal: low effective, open
collector output, optoelectronic isolation
Output signal judgment:
BIN comparator: good, over the standard, not good
list sweep comparator: IN/OUT for every sweep point and pass/fail for all the compared result.
INDEX: ADC ended
EOC: end of one test and comparison
Alarm: alarm for circuit interruption
The input signal: optoelectronic isolation
Keylock: lock the keys on the front panel
External Trigger: pulsewidth
≥1μS
9.2The operation description
9.2.1The definition for the signal line
The Handler interface has 3 signal: comparison output, control output and control input.
The signal line‘s definition for the BIN comparison and list sweep comparison is below:
Comparison signal lines:

Comparison output signal
/BIN1 - /BIN9, /AUX , /OUT, /PHI(the main parameter is higher)
，
/PLO(the main
parameter is lower)
，
/SREJ(the secondary parameter is not good). The signal line distribution
for comparison out is shown in figure 9-1.

Control output signal
/INDEX(analog test finished signal), /EOM(test ended and the compared data effective),
