Safety Summary
The following general safety precautions must be observed during all phases of operation,
service, and repair of this instrument. Failure to comply with these precautions or with speci c
WARNINGS elsewhere in this manual may impair the protection provided by the equipment.
In addition it violates safety standards of design, manufacture, and intended use of the
instrument.
The Agilent Technologies assumes no liability for the customer's failure to comply with these
requirements.
Note 4286A is designed for use in INSTALLATION CATEGORY II according to IEC
61010-1 and POLLUTION DEGREE 1 according to IEC 61010-1 and IEC 60664-1.
4286A is an INDOOR USE product.
Note LEDs in 4286A are Class 1 in accordance with IEC60825-1.
CLASS 1 LED PRODUCT
Ground The Instrument
To avoid electric shock hazard, the instrument chassis and cabinet must be connected to a
safety earth ground by the supplied power cable with earth blade.
DO NOT Operate In An Explosive Atmosphere
Do not operate the instrument in the presence of
ammable gasses or fumes. Operation of any
electrical instrument in such an environment constitutes a de nite safety hazard.
Keep Away From Live Circuits
Operating personnel must not remove instrument covers. Component replacement and internal
adjustments must be made by quali ed maintenance personnel. Do not replace components
with the power cable connected. Under certain conditions, dangerous voltages may exist even
with the power cable removed. To avoid injuries, always disconnect power and discharge
circuits before touching them.
DO NOT Service Or Adjust Alone
Do not attempt internal service or adjustment unless another person, capable of rendering rst
aid and resuscitation, is present.
DO NOT Substitute Parts Or Modify Instrument
Because of the danger of introducing additional hazards, do not install substitute parts or
perform unauthorized modi cations to the instrument. Return the instrument to a Agilent
Technologies Sales and Service Oce for service and repair to ensure that safety features are
maintained.
iv
Dangerous Procedure Warnings
Warnings , such as the example below, precede potentially dangerous procedures throughout
this manual. Instructions contained in the warnings must be followed.
Warning Dangerous voltages, capable of causing death, are present in this
instrument. Use extreme caution when handling, testing, and adjusting
this instrument.
v
Typeface Conventions
Bold Boldface type is used when a term is de ned. For example: icons are
symbols.
Italics Italic type is used for emphasis and for titles of manuals and other
publications.
Italic type is also used for keyboard entries when a name or a variable
must be typed in place of the words in italics. For example: copy
lename means to type the word copy, to type a space, and then to
type the name of a le such as file1.
Computer Computer font is used for on-screen prompts and messages.
4HARDKEYS5 Labeled keys on the instrument front panel are enclosed in 4 5.
NNNNNNNNNNNNNNNNNNNNNNNNNN NNNNN
SOFTKEYS Softkeys located to the right of the CRT are enclosed in .

Installation and Set Up Guide
This chapter provides the information necessary for performing an incoming inspection and
setting up your 4286A.
Incoming Inspection
Warning To avoid hazardous electrical shock, do not turn on the 4286A when there
are signs of shipping damage to any portion of the outer enclosure (for
example, covers, panel, or display)
Inspect the shipping container for damage. If the shipping container or cushioning material
is damaged, it should be kept until the contents of the shipment have been checked for
completeness and the 4286A has been checked mechanically and electrically. The contents
of the shipment should be as listed in Table 2-1. If the contents are incomplete, if there is
mechanical damage or defect, or if the 4286A does not pass the power-on selftests, notify the
nearest Agilent Technologies oce. If the shipping container is damaged, or the cushioning
material shows signs of unusual stress, notify the carrier as well as the Agilent Technologies
oce. Keep the shipping materials for the carrier's inspection.
The line voltage selector is set at the factory to correspond to the most commonly used line
voltage of the country of destination. If you want to change the line voltage, see \Changing
the Line Voltage Setting" in Appendix B.

Connecting the Test Fixture to the Test Head
To connect your xture to the Test Head, perform the steps listed below. (Figure 3-15 shows
the connection for 16192A as an example.)

Basic Measurement Procedures 3-13
5. Setting the Electrical Length of the Test Fixture
In the RF region, the wavelengths are short and are not negligible compared to the physical
transmission line length of the test xture. This causes a phase shift error. The phase shift
error is compensated by the electrical length parameter for the test xture. Because the
electrical length values for the Agilent Technologies test xtures are stored in the 4286A, you
can set the electrical length parameter by selecting the xture model number.
Setting Procedure
1. Press 4Cal5.
2. Press FIXTURE[] and then SELECT FIXTURE .
NNNNNNNNNNNNNNNNNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN

6. Fixture Compensation
Fixture compensation reduces the parasitic error existing between the test xture electrode
and the test head APC-7
connector (where the measurement accuracy is speci ed). Fixture
R
compensation consists of OPEN, SHORT and LOAD compensations. For basic measurements, the
OPEN and SHORT compensations are required.
Figure 3-16. Fixture Compensation
Performing SHORT Compensation
SHORT Compensation compensates for the residual impedance due to the test xture.
When you use a shorting device supplied with the 4286A (with option 004) or xture (with
option option 010), be sure to select the device of the same size as or at least closest to that of
the DUT. The dimensions for each shorting device are shown in Table 3-3.

7. Connecting the DUT to the Test Fixture
How to connect the DUT to the 16192A is shown in below as an example. The procedures for
the 16191A and 16193A are shown in Appendix C.
1. Push the lever and place the DUT on the electrode. 2. Release the lever to hold the DUT.
Caution Protect the instrument from ESD damage by wearing a grounding strap
that provides a high resistance path to ground. Alternatively, ground yourself
to discharge any static charge built-up by touching the outer shell of any
grounded instrument chassis before touching the test port connectors.
