Support for Your Product
Agilent no longer sells this product. Our service centers may be able
to perform calibration and repair if necessary, but no other support from
Agilent is available. You will find any other available product information on the
Agilent Test & Measurement website, www.tm.agilent.com.
HP References in this Manual
This manual may contain references to HP or Hewlett-Packard. Please note that
Hewlett-Packard's former test and measurement, semiconductor products and
chemical analysis businesses are now part of Agilent Technologies. We have
made no changes to this manual copy. In other documentation, to reduce
potential confusion, the only change to product numbers and names has been in
the company name prefix: where a product number/name was HP XXXX the
current name/number is now Agilent XXXX. For example, model number
HP8648A is now model number Agilent 8648A.

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. Hewlett-Packard Company assumes no liability for
customer's failure to comply with these requirements.
NOTE
HP 4155A/4156A comply with INSTALLATION CATEGORY II and
POLLUTION DEGREE 2 dened in IEC 1010-1.
HP 4155A/4156A are INDOOR USE products.
 GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cabinet must
be connected to an electrical ground. The power terminal and the
power cable must meet International Electrotechnical Commission
(IEC) safety standards.
 DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of ammable gases
or fumes. Operation of any electrical instrument in such an
environment constitutes a denite safety hazard.
 KEEP AWAY FROM LIVE CIRCUITS
Operation personnel must not remove instrument covers. Component
replacement and internal adjustments must be made b
y qualied
maintenance personnel. Do not replace components with 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 ADJUSTALONE
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 any unauthorized modication to
the instrument. Return the instrument to a Hewlett-Packard Sales
and Service Oce for services and repair to ensure that safety
features are maintained.
 DANGEROUS PROCEDURE WARNINGS
Warnings, such as 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.

Introduction
HP 4155A/4156A is an electronic instrument for measuring and analyzing the
characteristics of semiconductor devices. This one instrument allows you to
perform both measurement and analysis of measurement results.
highly accurate measurements.
HP 4155A/4156A has four highly accurate source/monitor units (SMUs), two
voltage source units (VSUs), and two voltage measurement units (VMUs).
The HP 4156A is designed for Kelvin connections and has high-resolution
SMUs (HRSMUs), so HP 4156A is especially suited for low resistance and low
current measurements.You can measure voltage values with a resolution of
0.2  V by using the dierential measurement mode of VMUs.
reliability testing.
HP 4155A/4156A can perform stress testing. That is, can force a specied dc
voltage or current for the specied duration.
Also, you can force ac stress by using pulse generator units (PGUs), which are
installed in HP 41501A SMU/Pulse Generator Expander. The HP 41501A is
attached to HP 4155A or HP 4156A, and can be equipped with a ground unit
(GNDU), high power SMU (HPSMU), two medium power SMUs (MPSMUs), or
two PGUs.
data storing and printing.
HP 4155A/4156A can print and store, in addition to performing measurement
and analysis.You can store measurement setup information, measurement
data, and instrument setting information on a 3.5-inch diskette inserted into
the disk drive of HP 4155A/4156A. And you can print the setting information
and measurement results on a plotter or printer that is connected to
HP 4155A/4156A.
remote control.
HP 4155A/4156A can be controlled by an external controller via HP-IB by
using remote control commands. These commands are based on Standard
Commands for Programmable Instruments (SCPI), so you can easily develop
measurement programs.
HP 4155A/4156A has internal HP Instrument BASIC, so you can develop and
execute measurement programs by using the HP 4155A/4156A only, without
using an external controller.
