Operating And Safety Precautions
Operating
Y
ou need observe only normal precautions when handling and operating the 16060A. Do not
exceed the operating input power
,voltage, and current level and signal type appropriate for
the instrument being used, refer to your instrument's operation manual.
Caution
Electrostatic discharge (
esd
)candamage the highly sensitive microcircuits in
your instrument. ESD damage is most likely to occur when the test xture
is being connected or disconnected. Protect the 16060A from ESD damage
by wearing agrounding strap that provides ahigh resistance path to ground.
Alternatively
,ground yourself to discharge any static charge build-up by
touching the outer shell of any grounded instrument chassis before touching
the test port connectors
.
Never touch atest port connector's center contact.
Use awork station equipped with an anti-static work surface
.
Service
The voltage levels in this xture do not warrant more than normal caution for operator safety
.
Nevertheless
,service should be performed only by qualied personnel.

Preparation for Use
Introduction
This chapter explains how to install the 16060A Transformer T
est Fixture
.The topics covered
include initial inspection, ambient environmental considerations, connecting the test xture for
use
, and repackaging the test xture for shipping.
Initial Inspection
This xture 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 test xture 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
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 16060A for any signs of damage
.

Repackaging the Test Fixture
If shipping to aAgilent T
echnologies service center is required, the test xture should be
repackaged using the original factory packaging materials.
Alteratively
,comparable packaging materials may be used. Wrap the test xture in heavy
paper and pack in anti-static plastic packing material. Use sucient shock absorbing material
on all sides of the 16060A to provide a thick, rm cushion and to prevent movement during
shipping. Seal the shipping container securely and mark it

Operation
Introduction
This chapter describes the features of the 16060A (Figure 3-1), and describes how to connect
atransformer to the test xture (Figure 3-3 and Figure 3-4), how to set the A:B switch for
dierent measurements, how to physically extend the measurement distance from the 4263A
using cables and test leads
, and describes the internal circuit of the 16060A.
F
or instructions on how to measure transformer parameters
,see the
4263A Operation Manual
.
Figure 3-1. T
est Fixture F
eatures
1. Four terminal pair BNC terminals
. These terminals are connected to the UNKNOWN
terminals of the 4263A .
2. A:B Switch. Switch A:B changes the connection between terminal \A" and terminal \B" to
select the transformer parameter to be measured.
3. COMMON terminals. These terminals are connected using test leads to the common (low)
terminals of the transformer to be measured as shown in Figure 3-3 and Figure 3-4.
Operation 3-1

4. Aterminal.
T
erminal A is connected using a test lead to one of the high terminals of the
transformer under test as shown in Figure 3-3 and Figure 3-4.
5. Bterminal.
T
erminal B is connected using atest lead to the other high terminal of the
transformer under test as shown in Figure 3-3 and Figure 3-4.
OPEN Correction
The 16060A has inherent stray capacitance that adds an error term which decreases
measurement accuracy
.T
ocancel these residual eects and thus minimize measurement error
,
use the measuring instrument's OPEN correction capability
.The procedure is described in
the instrument's operation manual. T
omake an OPEN setup for this procedure
,connect the
center conductors of \A" and \B" together by clipping the respective alligator clips together
,
and separate them from the likewise connected center conductors of the COMMON terminals
.
Figure 3-2 illustrates an OPEN connection setup
.
Figure 3-2. Making an OPEN
Note
The eects of the 4263A SHORT correction depend on the measurement
parameters.F
or more information on the SHORT correction function,
