z Input Signals
/I_E_TRIG: This signal is a measurement start signal. To start
measurement by setting low pulse to minimum 5us for
/I_E_TRIG signal. This is a low edge active.
/I_K_LOCK: This signal is to lock all front panel controls. The front panel
is disable when /I_K_LOCK is at low level, and enable
when /I_K_LOCK is at high level.

z Measurement Complete signal:
/O_INDEX: This signal will go the low level when analog measurement is
completed and will go the high level when next trigger is
active. The handler can then remove the DUT from the fixture
and replace it with another DUT during the time when
/O_INDEX is at low level.
z Compare Output Signals:
/O_BIN_1- /O_BIN_13 : The GO judgment is active according to the
measured value judgment results (low level),
for example, if the comparator assigns a
component to BIN1, the /O_BIN_1 line will go
the low level till T4 (see Handler Interface
Timing). /O_BIN_2 - /O_BIN_13 are all
inactive (high level).
/O_P_HI: Main parameter failure: When the main parameter is greater than
Max, it will go the low level till T4 (see Handler Interface
Timing).
/O_P_LO: Main parameter failure: When the main parameter is lower than
Min, it will go the low level till T4(see Handler Interface
Timing).
/O_P_OVER: It will go the low level when main parameter is greater than
Max or is lower than Min.
/O_S_REJ,/O_S_OVER: It will go the low level when secondary is greater
than D_Max (if MODE=C/D) or is lower than
D_Min.
