Agilent Technologies 4263B - Measuring High Inductance Transformers

4263B
8. The
measurement results
are shown
below.
R2, like
L2,
corresponds
to
the
side
of
the
transformer connected
to the
\A" terminal.
To
obtain the
resistance
of
the
other
side
of
the
transformer,
change the
A:B switch
setting
to
1:N.

Transformers
When
measuring
the
DCR
or
R2
of
a
high
inductance
coil
or
transformer
,
set
the
trigger
delay
time
(T
w
)
to
prevent
a
transient
of
the
test
signal
due
to
the
inductance
of
the
DUT
and
the
resistance
of
the
DUT
and
the
test
signal
source
.
