Keithley’s new SourceMeter®family is the first series of instruments designed specifically for test
applications that demand tightly coupled precision voltage and current sourcing and measurement. They build upon many of the technologies originally developed for Keithley’s popular line of
Source-Measurement Units (SMUs). All four SourceMeter models combine a precision, low-noise,
highly stable DC power supply with readback and a low-noise, highly repeatable, high impedance,
1
⁄2-digit multimeter. The result is a compact, single-channel, DC parametric tester. In operation,

these instruments can act as a V-Source, an I-Source, a V-Meter, an I-Meter, and an ohmmeter.
Manufacturers of communications, computer, automotive, and consumer electronics products
will find them invaluable for a wide range of design and production test applications.
By linking source and measurement circuitry in a single unit, these instruments offer a variety of
advantages over systems configured with separate source and measurement instruments. For
example, their compact half-rack size conserves precious “real estate” in the test rack or bench.
They also minimize the test station development, set-up, and maintenance time required, while
lowering the overall cost of system ownership. In addition, SourceMeters simplify the test process
itself by eliminating many of the complex synchronization and connection issues associated with
using multiple instruments.

Five Source and Measurement Range Choices
The SourceMeter family offers a choice of five sets of source and measurement ranges, so test system developers can select the instrument best suited for the types of components to be tested.
• The Model 2400 SourceMeter is a 20W instrument that allows sourcing and measuring voltage
from ±1µV to ±200V DC and current from ±10pA to ±1A. It’s well-suited for testing a wide range
of devices, including diodes, resistors, resistor networks, active circuit protection devices, and
portable battery-powered devices and components. It’s also useful for systems power sourcing
and I
testing applications.
DDQ
• The Model 2410 High Voltage SourceMeter is a 20W instrument that sources and measures voltage from ±1µV to ±1100V and current from ±10pA to ±1A. The higher voltage sourcing range
makes it a good choice for resistors and voltage coefficient testing, varistors, and high voltage
diodes, including switching, zener, RF diodes, and rectifiers. A 20mA measurement range gives
the Model 2410 the extra resolution needed for precision testing of high voltage varistors.
• The Model 2420 High Current SourceMeter is a 60W instrument designed to source and measure
voltage from ±1µV to ±60V and current from ±100pA to ±3A. Production test applications for the
Model 2420 include resistors and resistor network devices that must be tested at higher current
levels, thermistors, solar cells, batteries, and high current or medium power diodes, including
switching and Schottky diodes. The Model 2420 is also suitable for I
testing of CMOS inte-
DDQ
grated circuits and monitoring the current consumption of battery-powered medical devices
such as pacemakers.
• The Model 2425 100W SourceMeter extends the voltage range of the 2420 to 100V, enabling 100W
capability in the 1A range. Like the 2420, it also offers a 3A range with 60W power capability. The

Model 2425 was designed for production testing of medium-power devices
like DC-to-DC converters, power supplies, and other components requiring
between 60W and 100W of total DC power.
• The Model 2430 1kW Pulse SourceMeter offers the same DC source and
measurement ranges as the 2425, plus a unique 1kW pulse mode that
extends the upper current limit to 10A. This mode makes the Model 2430
ideal for measuring the breakdown voltage of many types of high-power
devices, including multi-layer varistors (MLVs) and semiconductor components. During production testing of these devices, breakdown voltage is
often measured under a high current pulse of up to 10A. The Model 2430
combines programmable bipolar voltage and current sourcing of up to 10A
@ 100V (pulsed) with all the high-speed testing capabilities common to the
Series 2400 family. The Model 2430 can be programmed to produce individual pulses or pulse trains up to 5ms wide and with varying duty cycle on
most source ranges. Pulses up to 2.5ms long and an 8% duty cycle can be
programmed on the instrument’s 1kW range. When combined with a PC
controller and the appropriate switching hardware, the Model 2430 provides an economical, high-throughput solution for high-power varistor testing, all in one compact, half-rack box. Other solutions offering compatible
capabilities, such as discrete semiconductor component testers, typically
cost four times as much as the Model 2430 and required significantly more
rack space.
All five SourceMeter instruments are suitable for making a wide range of DC
measurements, including resistance at a specified current or voltage, breakdown voltage, leakage current, insulation resistance, and electrical characterization.
Model 2400 Dynamic Range
High throughput for production testing
The 2400 line lets you perform high-speed single or multi-point pass/fail
testing on a wide range of components, such as network devices, circuit
protection devices, active discrete devices, and sensors. The line’s 1000
rdgs/s at 4½ digits through a GPIB (IEEE-488) connection ensures higher
throughput. The buffer memory can store up to 5000 5½-digit readings. An
on-board comparator simplifies high-speed pass/fail tests without the
delay of computer/ IEEE-488 interaction.

The 2400 line has built-in, user-definable math functionality to compute derived parameters such
as power dissipation, voltage coefficient, % deviation, alpha, ratio, and other mathematical formulas, such as mX+b.
A digital I/O interface lets you link the 2400 family to many popular component handlers, including Aetrium, Aseco, and Robotronics, for tight systems integration in binning, sorting, and similar
applications, which speeds up the production process. Included are start of test and end of test signals, three category bits, and a 5V, 300mA supply. A new digital I/O expander accessory provides 16
digital I/O lines for greater binning capacity, and can be used with any of the SourceMeter models.
A Source Memory List allows up to 100 instrument configurations to be stored in memory, each
containing source settings, sense (measurement) settings, and pass/fail criteria.
The 2400 line also has our unique Trigger-Link interface to provide seamless integration with
Keithley Series 7000 switching hardware for complete multi-point test solutions.
The 2400 family’s half-rack size saves valuable space, providing increased test capacity within a
given area. It is ruggedly designed for non-stop production environments with 75,000-hour MTBF.
It also has certification to CE and a full one-year warranty.
Optional Contact Check Function
In the production test environment, measurement errors
and false product failures can often be traced to a variety

of problems, including contact fatigue, breakage, or contamination, loose or broken connections, or relay failures.
Keithley’s optional Contact Check function, now available
T1
Hi Sense
for the Series 2400 SourceMeter line, makes it simple to
verify good connections quickly and easily, before an
automated test sequence begins.
The Contact Check function completes the verification
and notification process in just 350µs; comparable capabilities in other test equipment can require up to 5ms to

perform the same function. Contact Check can be
enabled with the controls on the instrument’s front panel
or remotely via the GPIB. Contact is verified simply by
making a differential measurement of the unknown resistance between a force lead and its sense lead (Kelvin con-

tacts) to a programmable reference resistance in an equivalent circuit; in other words, only the difference between
the two resistances is measured and no energy passes
through the DUT during the operation. If the value of that
differential measurement is too high, the contact has

failed the check. Three reference value choices are offered
to accommodate different system configurations.
The software that controls the Contact Check function offers three methods of fault notification.
The instrument’s front panel display indicates “Open Lead” and a flag is set in a register that can be
queried through the GPIB port. Once a part has failed the contact check, the instrument’s digital
I/O can also be used to synchronize with an automatic handler to index to the next part or to retest
the same part. The output of the SourceMeter is automatically shut off when a part fails the contact check and is not re-activated until good contact is verified. This feature protects the device
under test (DUT) from damage and the operator from potential safety hazards.
Source memory list for sequenced testing
The source memory list is a key 2400 family feature for production testing. This built-in “programmable test sequencer” lets you configure a sequence of up to 100 different tests. Each test can
contain totally different test conditions, measurements, math, pass/fail, or binning criteria. The
tests are executed sequentially without additional external commands. Conditional branching leads
to different points on the test list, depending on results. The source memory list resides in batterybacked memory and can be accessed with or without a computer. The example shows a three-step
diode test. The setup for each test would be stored in a separate source memory location. One IEEE
trigger would initiate the execution of the sequence of three tests.

Unique 6-Wire Ohms Technique
SourceMeter units can make standard 4-wire, split Kelvin, and 6-wire, guarded ohms measurements, and can be configured for either the constant current or constant voltage method. When
used with a high-speed switching mainframe such as the Keithley Model 7001 or 7002 Switch Mainframe, the Model 2400 SourceMeter is well-suited for testing a wide range of resistor network
devices. The 6-wire ohms technique, unique to these instruments, uses Guard and Guard Sense
leads in addition to the 4-wire Sense and Source leads to guard out parallel current paths when
measuring networks or hybrid circuits. This technique avoids the complications of the DUT being
shunted by other resistances in the circuit, which can create measurement errors and slow
throughput. This broad range of resistance measurement capabilities makes SourceMeter instruments ideal for production testing of a wide range of resistive devices, including isolated and
bussed resistor networks, R/2R ladder resistor networks, and dual terminator resistor networks.
A Broad Range of Component Test Applications
• Diode Testing
SourceMeter units can source and measure voltage and
current quickly, then switch test configurations automatically, which makes them ideal for measuring the
forward voltage, breakdown voltage, and leakage current of devices such as signal diodes, RF diodes, zener
diodes, LEDs, LED display, and laser diodes. They also
offer single or multi-point pass/fail criteria, a digital I/O
for automated binning, programmable compliance,
and a source memory list for automating test
sequences with conditional branching, which makes
them a good choice for fast pass/fail, go/no-go diode
verification.
• Testing Resistive Devices and Networks
Typically, tests on resistor networks fall into one of three
general measurement categories: standard 4-wire
Kelvin measurements, 6-wire guarded ohms or delta resistance measurements, or “Y” circuit or buried node
resistance measurements (also called split Kelvin measurements). All tests are basically single-point resistance measurements performed using either constant
current or constant voltage. SourceMeter instruments
allow the use of either technique and can adjust the values for the source and measurement ranges to accommodate the manufacturer’s specifications, to ensure
maximum accuracy/reliability and measurement
