Using Handler Interface
You can output the measurement end signal, the sorting result of the
comparator function, and other data from the Keysight E4981A, as well as
input an external trigger signal or a key lock signal to the E4981A, through the
handler interface. This chapter also gives information required to configure an
auto-sorting system that combines the E4981A and a handler in using the
handler interface and the comparator function.
Output of Comparator Sorting Result
When the comparator function is ON, the comparator sorting result is output
through the handler interface.
between the comparator sorting result and the output signals of the handler
interface (/BIN1 - /BIN9, /AUX_BIN, /OUT_OF_BINS, /PHI, /PLO, and /SREJ).
When the comparator function is OFF, no signals are output, except for
/INDEX, /EOM, and /ALARM. /INDEX and /EOM stay LOW. /ALARM, as
when the comparator is ON, is output when an error occurs.
EXT_TRIG, regardless of the ON/OFF state of the comparator function, is
active when the trigger mode is set to the external trigger (EXT). When
/KEY_LOCK is LOW, regardless of the ON/OFF state of the comparator
function, the key lock state remains unchanged.
