Overall
Block
Diagram
The
4349B
doesn't
have
a
test
voltage
source
,
and
an
external voltage
source
must
be
supplied
for
operation.
The
4349B
has
four
input
channels
,
form
which
the
test current
owing
through
the
DUT
are
input.
The
multiplexer
switches
four
channels
on
a
single measurement
trigger
.
Each
V
,
which
is
proportional
to
the
input
I,
is
analog-to-digital converted.
The
CPU
calculates
I
from
the
converted
data,
then
calculates
the
DUT's
resistance
R,
by
dividing the
measurement
voltage
by
the
measured
current.
Note
The
test
voltage
is
data which
must be
input by
the front-panel
keys
or
through
GPIB
interface
.
The
4349B itself
has neither
voltage output
nor voltage
measurement
capability
.
