Preparation for Use
Introduction
This chapter explains how to install the 16117C Low Noise T
est Lead. The topics covered
include initial inspection, ambient environmental considerations, connecting the adapter for
use
, and repackaging the adapter for shipment.
Initial Inspection
The adapter has been carefully inspected electrically and mechanically before being shipped
from the factory
.It
should be in perfect physical condition, no scratches
,dents or the like
,and
it should be in perfect electrical condition. V
erify this by carefully performing an incoming
inspection to check the adapter for signs of physical damage and missing contents
.If any
discrepancy is found, notify the carrier and Agilent T
echnologies
.Y
our Agilent T
echnologies
sales oce will arrange for repair and replacement without waiting for the claim to be settled.
1. Inspect the shipping container for damage
,and keep the shipping materials until the
incoming inspection is completed.
2. V
erify that the shipping container contains everything shown in Figure 2-1 and listed in
T
able 2-1.
3. Inspect the exterior of the 16117C for any signs of damage
.

Connecting the A
dapter for Use
The 4339B connection with 16117C has two congurations: oating and grounded DUT
measurement congurations
.The connections are dierent for each conguration. The
connections are as shown in Figure 2-2 and Figure 2-3.

arning
Do NOT touch the electrode and UNKNO
WN connector while the High
V
oltage indicator is lit which shows the 4339B 's output is ahigh voltage
of up to 1000 Vdc maximum. You must operate after turning o the
voltage source output and you have conrmed the high voltage indicator
is turned o.

ackaging the A
dapter
If shipment to aAgilent T
echnologies service center is required, each adapter should be
repackaged using the original factory packaging materials.
Alteratively
,comparable packaging materials may be used. Wrap the adapter in heavy paper
and pack in anti-static plastic packing material. Use sucient shock absorbing material on
all sides of the 16117C to provide athick, rm cushion and to prevent movement. Seal the
shipping container securely and mark it

Making a Custom T
est Fixture
This section describes how to make a custom test xture for the 4339B.
Note
When you make acustom test xture using the 16117C,you must observe the
usage guidelines described in this section.
Conguration
The 16117C is provided so the user can make custom test xtures for the 4339B.Figure 3-2
shows an simplied conguration of test xture in oating DUT measurement with the 16117C.
Figure 3-2. Floating DUT Measurement Conguration
The BNC connector provides source voltage up to 1000 V
.Atriaxial connector is used for the
measured signal path. The triaxial connector's center conductor carries the signal. The inner
shield is aGuard, and the outer shield is the ground. Using a guard circuit eliminates the
external noise to the center conductors
. The Guard must extend as close as possible to the DUT
contact, but not connected.
For information about the Grounded DUT measurement conguration, refer to
4339B High
Resistance Meter Operation Manual
.
3-2 Operation

Interlock Circuit
The interlock circuit automatically enables interlocking the source voltage and current limit
function. T
oenable this function in your custom test xture, the 16117C provides an interlock
cable
.This section describes how to use interlock circuit to meet your custom test xture
requirements
.
Figure 3-3 shows pin assignments for the interlock cable
.
Figure 3-3. Interlock cable Assignment (Wiring Side View)
The interlock cable has six lines. The 4339B changes some settings: V
oltage Output, Current
Limit, and Resistivity Mode, depending on the interlock status

The ID signals are used by the 4339B to identify the current limit and the output voltage
performance requested by the test xture
.The 4339B is programmed beforehand to change the
current limit and output voltage settings according to the ID line status
.The ID status
