Introduction
The
4284A
is
a
general
purp

LCR
meter for

The
4284A
is
used
for
ev

LCR

materials,
and semiconductor
devices
o
v

a
wide
range
of
frequencies
(20

to
1
MHz
)
and

to

). With
Option 001
the
4284A
's
test

range spans
5mV
to
20
V

,
and
50

to
100

.
The
4284A

C-D

with
a
basic
accuracy
of
6
0.05%

at
all
test
frequencies
with
six
digit
resolution
(the
dissipation
factor
resolution
is 0.000001)
on
ev
ery
range.
With
its
built-in
comparator,
the
4284A
can
output
comparison/decision
results
for
sorting
comp

in
to
a
maxim
um
of
ten bins.
By using
the
handler
in
terface
and
scanner
in
terface
options,
the
4284A
can
easily b
e com
bined with
a comp

a
scanner,
and
a
system

to
fully
automate

The
4284A

The GPIB in
terface is a standard in
terface on
the 4284A and can b e
used to build an automatic test system to completely c
haracterize
new componen
ts and materials, and to fully automatic pro duction
line testing.
The 4284A
with Option 002 can apply a 0 to 20A (Maximum
40A : When t
wo 42841As are paralleled.) DC curren
t bias to the
DUT (Device Under Test). So, high current biased impedance
measurement of coils or transformers can be p erformed easy, fast and
safe.
