Connecting the
T
est
Fixture
The test
xture
used
in
this
example
is
the
16092A
Spring
Clip
T
est
Fixture
.
Connect
the
test
xture
to
the
test
kit
referring
to
the
documentation
for
the
16092A
Spring
Clip T
est Fixture
.
Setting
the
Electrical
Length
of
the
T
est
Fixture
Connecting
a
test
xture
adds
an
extra
electrical
length
to
the
test circuit.
This electrical
length, which is specic to the test xture you use
, must be known to the 4395A so that it
can
compensate for the extra electrical
length and eliminate errors due to phase shifts
.
Although the 4395A incorporates a database of
Agilent test xtures with their own electrical
lengths, the 16092A test xture is not
contained in this database
. Therefore
, you need to
manually set its electrical length.
Follow these steps:
1. Press 4
Meas

2.
Choose
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
FIXTURE [NONE]
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
MODIFY [NONE]
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
DEFINE EXTENSION .
3. The 16092A test xture has an electrical length of 0.0034 m. To enter this electrical length,
press 4
