time
before
a
DUT
is
measured.
The charge
time denes
the waiting
time
when
the
4339B
triggered
a
measurement to
when the
measurement will
actually start.
The
test
voltage
is
applied
during
this time

Sets
the
sequence
measurement
mode
to
ON
or
OFF
,
and
selects
the
source
for the
ARM event
detector
.
When
the
ARM
event
is
detected,
the
4339B
enables
the
output
test
voltage
and
applies
the
test
voltage
to
DUT
.
After
charge-time
wait,
4339B
move
from
the
ARM
event
detection
state
to
the
TRIG
event
detection
state
.
When
BUS
,
EXTernal
,
or
MANual
is
selected
as
the
ARM
source
,the
4339B automatically
enables
the
test
voltage
output
at
the
time
an
ARM
event
is
detected,
and applies
the test
voltage
to
the
DUT
.
After
the
measurement,
the
4339B
automatically
turns
OFF
the
test
voltage
output.
When
IMMediate
is
selected,
the
ARM
event
has
no
eect
on
test
voltage
output
enabling
or
disabling,
you
must
control
test voltage
output.
Only
one
trigger
source
can
be
specied
at
a
time for
a
given
event
detector
.
The
available

are:
