Extension
The
43961A
impedance
test
kit
has A
CP-7 connectors
that are
intended for
direct
connection
with
a
test
xture
.
However,
you can
use the
4395A's
port
extension
feature
to
connect
an
extension
cable
between
the test
kit and
xture.
Note
Y
ou
must
determine
the
electrical
length
of
the
extension
cable
before
using
it
with
the
aid
of
the
port
extension
feature
.
F
ollow
these
steps:
1.
Connect
the
cable
to
the APC-7
connector of
the 43961A
impedance test
kit.
