Information
This
section
discuss
the
4263B's
theory of
operation and
the technical
information.
Overall
Impedance Measurement
Theory
The
4263B measures
the
impedance
of
the
Device
Under
T

)
in
the
following
manner:

Model
of
Impedance
Measurement
Figure
3-6
shows
the
simplied
model
of
the
4263B
impedance
measurement.
Vs
is
the
test
signal
level
(voltage)
and
Rs
is
the
source
resistance
.
If
the
current
across
the
DUT
is
I
when
a
test
signal
voltage
V
is
applied,
the
DUT's
impedance
,
Z,
is
expressed
by
,
Z
=
V
I
