is
asserted,
all
of
the

disabled.
19 /EXT
TRIG
External
Trigger
:
4263B
is
triggered
on
the
rising

to this
pin, when
the
trigger

Common
for

28 /PHI This
signal
is asserted,
when the
comparison result
of the
primary
parameter
is
High.

29 /PIN This
signal
is
asserted,
when
the
comparison
result
of
the
primary
parameter
is
In.
3
30 /PLO This
signal
is
asserted,
when
the
comparison
result
of
the
primary
parameter
is
Low
.
3
31 /SHI This
signal
is
asserted,
when
the
comparison
result
of
the
secondary parameter
is
High.
3
32 /SIN This
signal
is
asserted,
when
the
comparison result
of
the
secondary
parameter
is
In.
3
33 /SLO This signal
is
asserted,
when
the
comparison
result
of
the
secondary
parameter
is
Low
.

This
signal
is
asserted,
when
the

42 /ALARM Alarm
:
This
signal
is
asserted,
when
a
power
failure
occurs
or
the
error
(
E11

, E13
, E14
,
E15
,
E20
,
or

occurs
.
43 /INDEX Index
:
This signal
is asserted,
when an
analog
measurement
is
complete
and
the
4263B
is
ready
for the
next DUT
to be
connected to
the
UNKNOWN
terminals
.
The
measurement
data, however
,is
not valid
until
the
line
/EOM
is
asserted.

44 /EOM End of Measurement :
This signal is asserted, when the measurement data and comparison results are valid.

1 The / (slash) means that the signal is asserted when LOW
.
2 If an error occurs and the 4263B stops operation, the 4263B will not trigger a measurement if it receives the /EXT
TRIG signal.
3 If an error occurs and the 4263B stops operation, these lines retain the condition that existed just before the error
occurs.
