Safety Precautions

The following safety precautions should be observed before using
this product and any associated instrumentation. Although some in
struments and accessories would normally be used with non-haz­ardous voltages, there are situations where hazardous conditions
may be present.

This product is intended for use by qualified personnel who recog­nize shock hazards and are familiar with the safety precautions re­quired to avoid possible injury. Read and follow all installation,
operation, and maintenance information carefully before using the
product. Refer to the manual for complete product specifications.

If the product is used in a manner not specified, the protection pro­vided by the product may be impaired.

The types of product users are:

Responsible body is the individual or group responsible for the use
and maintenance of equipment, for ensuring that the equipment is
operated within its specifications and operating limits, and for en
suring that operators are adequately trained.

Operators use the product for its intended function. They must be
trained in electrical safety procedures and proper use of the instru
ment. They must be protected from electric shock and contact with
hazardous live circuits.

Maintenance personnel perform routine procedures on the prod­uct to keep it operating properly, for example, setting the line volt­age or replacing consumable materials. Maintenance procedures
are described in the manual. The procedures explicitly state if the
operator may perform them. Otherwise, they should be performed
only by service personnel.

Service personnel are trained to work on live circuits, and perform
safe installations and repairs of products. Only properly trained ser
vice personnel may perform installation and service procedures.

Keithley products are designed for use with electrical signals that
are rated Measurement Category I and Measurement Category II, as
described in the International Electrotechnical Commission (IEC)
Standard IEC 60664. Most measurement, control, and data I/O sig
nals are Measurement Category I and must not be directly connect­ed to mains voltage or to voltage sources with high transient over­voltages. Measurement Category II connections require protection
for high transient over-voltages often associated with local AC
mains connections. Assume all measurement, control, and data I/O
connections are for connection to Category I sources unless other
wise marked or described in the Manual.

Exercise extreme caution when a shock hazard is present. Lethal
voltage may be present on cable connector jacks or test fixtures.
The American National Standards Institute (ANSI) states that a
shock hazard exists when voltage levels greater than 30V RMS,

42.4V peak, or 60VDC are present. A good safety practice is to ex

pect that hazardous voltage is present in any unknown circuit
before measuring.

Operators of this product must be protected from electric shock at

-

all times. The responsible body must ensure that operators are pre
vented access and/or insulated from every connection point. In
some cases, connections must be exposed to potential human con
tact. Product operators in these circumstances must be trained to
protect themselves from the risk of electric shock. If the circuit is
capable of operating at or above 1000 volts, no conductive part of

the circuit may be exposed.

Do not connect switching cards directly to unlimited power circuits.
They are intended to be used with impedance limited sources.
NEVER connect switching cards directly to AC mains. When con
necting sources to switching cards, install protective devices to lim­it fault current and voltage to the card.

Before operating an instrument, make sure the line cord is connect­ed to a properly grounded power receptacle. Inspect the connecting
cables, test leads, and jumpers for possible wear, cracks, or breaks

­before each use.

When installing equipment where access to the main power cord is
restricted, such as rack mounting, a separate main input power dis

­connect device must be provided, in close proximity to the equip-

ment and within easy reach of the operator.

For maximum safety, do not touch the product, test cables, or any
other instruments while power is applied to the circuit under test.
ALWAYS remove power from the entire test system and discharge
any capacitors before: connecting or disconnecting cables or jump
ers, installing or removing switching cards, or making internal
changes, such as installing or removing jumpers.

Do not touch any object that could provide a current path to the com­mon side of the circuit under test or power line (earth) ground. Always

­make measurements with dry hands while standing on a dry, insulated

surface capable of withstanding the voltage being measured.

The instrument and accessories must be used in accordance with its
specifications and operating instructions or the safety of the equip
ment may be impaired.

­Do not exceed the maximum signal levels of the instruments and

accessories, as defined in the specifications and operating informa­tion, and as shown on the instrument or test fixture panels, or
switching card.

When fuses are used in a product, replace with same type and rating

­for continued protection against fire hazard.

Chassis connections must only be used as shield connections for
measuring circuits, NOT as safety earth ground connections.

If you are using a test fixture, keep the lid closed while power is ap­plied to the device under test. Safe operation requires the use of a
lid interlock.

wire recommended in the user documentation.

!

The symbol on an instrument indicates that the user should re­fer to the operating instructions located in the manual.

The symbol on an instrument shows that it can source or mea­sure 1000 volts or more, including the combined effect of normal
and common mode voltages. Use standard safety precautions to
avoid personal contact with these voltages.

The symbol indicates a connection terminal to the equipment
frame.

The WARNING heading in a manual explains dangers that might
result in personal injury or death. Always read the associated infor­mation very carefully before performing the indicated procedure.

The CAUTION heading in a manual explains hazards that could
damage the instrument. Such damage may invalidate the warranty.

Instrumentation and accessories shall not be connected to humans.

Before performing any maintenance, disconnect the line cord and
all test cables.

To maintain protection from electric shock and fire, replacement
components in mains circuits, including the power transformer, test
leads, and input jacks, must be purchased from Keithley Instru­ments. Standard fuses, with applicable national safety approvals,
may be used if the rating and type are the same. Other components
that are not safety related may be purchased from other suppliers as
long as they are equivalent to the original component. (Note that se
lected parts should be purchased only through Keithley Instruments
to maintain accuracy and functionality of the product.) If you are
unsure about the applicability of a replacement component, call a
Keithley Instruments office for information.

To clean an instrument, use a damp cloth or mild, water based
cleaner. Clean the exterior of the instrument only. Do not apply
cleaner directly to the instrument or allow liquids to enter or spill
on the instrument. Products that consist of a circuit board with no
case or chassis (e.g., data acquisition board for installation into a
computer) should never require cleaning if handled according to in
structions. If the board becomes contaminated and operation is af­fected, the board should be returned to the factory for proper
cleaning/servicing.

Introduction

This user’s manual describes operation of the 4510-QIVC and 4511-QIVC Quad IV cards. After
reading this document, you should be able to perform the following tasks:

• Open up the mainframe.

• Plug a card into the mainframe.

• Connect the hardware necessary to operate a card with the mainframe.

• Use the Keithley 4510-QIVC and 4511-QIVC Embedded Sweep Example program.

• Perform basic programming tasks to control and take measurements with the card using the

supplied library of driver calls.

General information

Features

The 4510-QIVC and 4511-QIVC cards are intended to provide parallel real-time source/measure
capability in a cost-effective, compact, and scalable platform. These applications typically take
two forms: multi-channel I-V test or multi-channel intelligent power supply. Applications requir
ing multi-channel I-V capability include on wafer test of LEDs, VCSELs, and Optoelectronic ICs
where a large number of channels need to perform I-V sweeps in parallel or in coordination with
each other. Applications that require multi-channel intelligent power supply capability include
accelerated life test and functional device test that require large numbers of channels to sourcing
currents or voltages while monitoring power consumption.

-

The 4510-QIVC provides three current source ranges: 30mA, 100mA, and 500mA, at up to 6V
compliance. The 4511-QIVC is a higher current unit also providing three source current ranges
at 100mA, 300mA, and 1A without compromising instrument specifications or functionality.
Both cards also have a programmable ±10V voltage source with source read-back and precision
three-range (10µA, 500µA, 10mA) current measurement. Together these cards provide coverage
for a wide variety of source/measure applications.

The following list summarizes the major features of 4510-QIVC and 4511-QIVC:

• Channel Density — The channel density provided by the 4510-QIVC and 4511-QIVC
allows for testing of up to 36 channels in a single 4500-MTS chassis. Channel density allows
you to perform massively parallel tests to accelerate throughput.

• Source/Measure Combinations — The 4510-QIVC and 4511-QIVC plug-in cards offer
modular precision source-measure capability. Each card provides four channels, and each
channel includes a current source subchannel and a voltage source subchannel. Each channel
also includes an instrument grade A/D converter for highest possible throughput without
compromising precision.

• Integrated Test System — The internal PC and Windows® 2000 Operating System of the
4500 system allow users to eliminate the test system controller from new test stands. With
ethernet interface capability, the 4500-MTS can interface directly with facility databases for
transfer of test data.

• User Safety — The 4510-QIVC and 4511-QIVC provide for user safety (electrical and
optical) for the target component types. Voltage source capability will not exceed 48V on any
circuit. The system also provides for software and hardware abort capability upon interlock.

• High Test Throughput and Accuracy — The 4510-QIVC and 4511-QIVC provide fast and
accurate measurements.

4510-QIVC and 4511-QIVC Quad IV Cards User’s Manual Getting Started 1-3

• User Interface — The 4500 comes with standard drivers for the LabView,
LabWindows/CVI, Visual C/C++, and Visual Basic® programming environments. In
addition, application demo programs in LabView, LabWindows/CVI, and Visual Basic

Introduction

This section includes information on card installation, software installation, and connecting
DUTs (Device Under Test) to the card.

Connection precautions

WARNING Read all safety precautions listed at the beginning of this manual. The

following safety practices must be used to protect operators and other
users of this product from potential exposure to electrical hazards:

• Operators must be protected from electrical hazards at all times.

• The interlock is required for safe operation. The test fixtures

must ensure that the interlock circuit is disabled (source outputs
inhibited) so that an operator is not exposed to any harmful
conditions. See

• Maximum isolation from earth ground is ±20V. Exceeding this

value may result in a shock hazard.

• When making connections, do not leave any exposed

connections. Be sure that all external circuits are properly
insulated.

“Interlock,” page 2-13 for interlock information.

could affect measurement quality. Do not touch PC board traces or
edge connector contacts. Use a ground strap and proper grounding
techniques to avoid damage caused by static discharge.

NOTE A maximum of eight 4511-QIVC cards should be installed in a

4500-MTS mainframe. Operation with nine 4511-QIVC cards is not
recommended.

1. Remove the desired slot cover plate from the rear panel by removing the securing screw (1)
and bracket.

2. Remove the PCI card retainer by loosening the three (3) retaining screws and sliding the
bracket off.

3. Carefully remove the card from its antistatic (shipping) bag.

4. Position the card above the appropriate PCI slot, aligning the card with the card edge rails
and rear slot opening. Line up the edge connectors with the slot connectors on the backplane,
and then carefully insert the card into those connectors. Make sure the card is properly seated
in all connectors by applying firm, even pressure to the top edge of the card.

5. Install the screw (1) at the rear panel location to secure the card.

6. Re-install the PCI card retainer; retighten the three (3) screws.

7. Replace the mainframe top cover plate and cover.

Block diagram

Figure 2-4 shows a block diagram of one channel of the 451x-QIVC cards. Each of the four

channels is identical.

Each of the four channels has two subchannels: I-Source and V-Source. In addition to sourcing
current, the I-Source subchannel measures the voltage and, optionally, the current (current read
back). The current source subchannel is useful for testing many types of DUTs. The current
source sections include circuitry for current readback, voltage measurement, and compliance,
while the voltage source section has current measurement and voltage readback circuits. Both
sections include output relays that control connections to the DUTs.

diode anode (DUT A), while I-SOURCE LO and V-MEASURE LO are connected to the diode
cathode. V-SOURCE HI is connected to the diode anode (DUT B), while V-SOURCE LO
and V-SOURCE SENSE LOW are connected to the diode cathode. GUARD is connected to
the shield of the cable connected to V-SOURCE HI to shield the sensitive signal path against
interference. The GUARD connection may be required when high quality low current
(10µA range) measurements are required.
