Transducer
Section
The
transducer section
measures
the
vector
voltage
across
the
DUT
,
and
the
current
owing
through
the DUT
by
converting
the
current
to
voltage
.
The
transducer
also
includes
a switch
used
by the
Option
001
(Transformer
P
arameter
Measurement),
and
the
contact
check
voltage
source
.

shows
the

The
voltage
across
the
DUT
is
measured
at
the
H
POT
and
L
POT
connectors
using
a
dierential
amplier
.
The
current
owing
through
the
DUT
and
owing
into
the
L
CUR
connector
is
converted
to
voltage
by
an
I-V
converter
.
The
dierential
amplier
measures
the
voltage
between an
I-V
converter
output
and
the inverting
input of
the converter
.
The
inverting
input
of
the
converter
,
thus
L
CUR
,
is
at
virtual
ground, because
of the
very high
input impedance
and
very
high
open
loop
gain
of the
operational amplier
used in
the I-V
converter
.
