1693 RLC Digibridge
Operation
“axial” wire must be at least 3 mm long (0.12 in.].
The overall length of the DUT, including the axial
wires must be at least 22 mm (0.866 in.).
Insert the DUT so that one lead makes connection on
the left side of the test fixture, the other lead on the
right side. Insertion and removal are smooth, easy
operations and connections are reliable if leads are
reasonably clean and straight. Press the DUT down
so that the leads enter the slots in the adaptors as far
as they go easily.
Be sure to remove any obvious dirt from leads before
inserting them. The test-fixture contacts will wipe
through a film of wax, but can become clogged and
ineffectual if dirty leads are inserted repeatedly. Be
sure to insert only one thing into each half of the test
fixture, at anyone time. (If any object is inserted into
the same slot with a DUT lead, it will probably NOT
make true “Kelvin” connections.)
NOTE: For a DUT with very short leads, it is impor-
tant to orient each adaptor so that its internal contacts
(which are off center) are close to the DUT. To remove
each adaptor, lift with a gentle tilt left or right (never
forward or back) .
3.2.4 1657-9600 Banana Plug
Extender Cable
The 1657-9600 is a male banana plug extender cable
with shielded 4-terminal Kelvin connections and
guard (3 feet in length) for connecting to 1659, 1689-
9700, 1692 Digibridges and 1689-9600 Remote Test
Fixture. Terminated with 5 banana plugs and includes
5 alligator clip. Each banana plug has a different color
banana plug, red for high and black for low. White
bands for potentials and green band for ground see
Figure 3-10 below.

cable
Note: The H connectors on the 1689-9602 cable are
deliberately connected to the “-” terminals on the test
fixture and vice versa.
