The Power of Three Instruments in One
The tightly coupled nature of a SourceMeter instrument provides many advantages over separate
instruments. For example, it provides faster test times by reducing GPIB traffic and simplifies the
remote programming interface. It also protects the device under test from damage due to accidental
overloads, thermal runaway, etc. Both the current and voltage source are programmable with readback to help maximize device measurement integrity. If the readback reaches a programmed compliance limit, then the source is clamped at the limit, providing fault protection.

Keithley’s SourceMeter family is designed specifically for test
applications that demand tightly coupled sourcing and measurement. All SourceMeter models provide precision voltage and current sourcing as well as measurement capabilities. Each
SourceMeter instrument is both a highly stable DC power source
and a true instrument-grade 5
1
⁄2-digit multimeter. The power
source characteristics include low noise, precision, and readback.
The multimeter capabilities include high repeatability and low
noise. The result is a compact, single-channel, DC parametric
tester. In operation, these instruments can act as a voltage source,
a current source, a voltage meter, a current meter, and an ohmmeter. Manufacturers of components and modules for the communications, semiconductor, computer, automotive, and medical
industries will find the SourceMeter instruments invaluable for a
wide range of characterization and production test applications.
Advantages of a Tightly Integrated Instrument
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, they minimize the time required for test station development, setup, and maintenance, while lowering the overall cost
of system ownership. They simplify the test process itself by eliminating many of the complex synchronization and connection

I-V Characteristics
All SourceMeter instruments provide four-quadrant operation. In the first and third quadrants they
operate as a source, delivering power to a load. In the second and fourth quadrants they operate as a
sink, dissipating power internally. Voltage, current, and resistance can be measured during source or
sink operation.

Automation for Speed
A SourceMeter instrument streamlines production testing. It sources voltage or current while making
measurements without needing to change connections. It is designed for reliable operation in nonstop production environments. To provide the throughput demanded by production applications,
the SourceMeter instrument offers many built-in features that allow it to run complex test sequences
without computer control or GPIB communications slowing things down.
Standard and Custom Sweeps
Sweep solutions greatly accelerate testing with
Stop
automation hooks. Three basic sweep waveforms
are provided that can be programmed for single-
Start
event or continuous operation. They are ideal for
I/V, I/R, V/I, and V/R characterization.

Digital I/O Interface
The digital I/O interface can link the SourceMeter instrument to many popular component handlers, including Aetrium, Aeco, and Robotronics.
Other capabilities of the interface include:
• Tight systems integration for applications such as binning and sorting
• Built-in component handler interface
• Start of test and end of test signals
• 5V, 300mA power supply
• Optional expander accessory (Model 2499-DIGIO) adds 16 digital I/O lines
Trigger Link Interface
All SourceMeter instruments include Keithley’s unique Trigger Link interface which provides high-speed, seamless communications with many of
Keithley’s other instruments. For example, use the Trigger Link interface to
connect a SourceMeter instrument with a Series 7000 Switching System for
a complete multi-point test solution. With Trigger Link, the 7000 Series
Switching Systems can be controlled by a SourceMeter during a high-speed
test sequence independent of a computer and GPIB.
Optional Contact Check Function
The Contact Check function makes it simple to verify good connections
quickly and easily before an automated test sequence begins. This eliminates measurement errors and false product failures associated with contact fatigue, breakage, contamination, loose or broken connection, relay
failures, etc. Some capabilities of this function are:
• 350µs verification and notification process time
• The output of the SourceMeter instr ument is automatically shut off after
a fault and is not re-activated until good contact is verified, protecting
the device under test from damage and the operator from potential
safety hazards
• 3 pass/fail threshold values: 2Ω, 15Ω, and 50Ω
• No energy passes through the device under test during the operation
• Enabled either from the front panel or remotely over the GPIB
• 3 fault notification methods
Unique 6-Wire Ohms Technique
SourceMeter instruments can make standard 4-wire, split Kelvin, and 6wire, guarded ohms measurements and can be configured for either the
constant current or constant voltage method. The 6-wire ohms technique:
• Uses guard and guard sense leads in addition to the 4-wire sense and
source leads
• Locks out parallel current paths when measuring resistor networks or
hybrid circuits to isolate the component under test
• Allows users to configure and plot data easily from Series 2400
SourceMeter instruments, making characterization of two, three, and
four terminal devices a snap

NOTES
1. 2400, 2410 Only: Specifications valid for continuous output currents below 105mA. For operation above 105mA con-
tinuous for >1 minute, derate accuracy 10%/35mA above 105mA.
2. Full operation (1A) regardless of load to 30°C (50°C for Model 2420 and 2440). Above 30°C (50°C for Model 2420
and 2440) ambient, derate 35mA/°C and prorate 35mA/Ω load. 4-wire mode. For current sink operation on 1A, 3A,
or 5A ranges, maximum continuous power is limited to approximately 1/2 rated power or less, depending on current, up to 30°C ambient. See power equations in the User’s Manual to calculate allowable duty cycle for specific
conditions.
3. For sink mode, 1µA to 100mA range, accuracy is:
Model 2400: ±(0.15% + offset*4). Models 2410, 2420, 2425, 2430, 2440: ±(0.5% + offset*3).
For 1Arange, accuracy is:
Model 2400: ±(1.5% + offset*8). Models 2410, 2420, 2425, 2430, 2440: ±(1.5% + offset*3).
4. 10A range only in pulse mode. Limited to 2.5ms pulse width maximum. 10% duty cycle maximum.
5. Speed = Normal (1 PLC). For 0.1 PLC, add 0.005% of range to offset specifications, except 200mV, 1A, 10A ranges,
add 0.05%. For 0.01 PLC, add 0.05% of range to offset specifications, except 200mV, 1A, 10A ranges, add 0.5%.
6. Accuracies apply to 2- or 4-wire mode when properly zeroed.
7. In pulse mode, limited to 0.1 PLC measurement.
8. Model 2400 and 2400-C only.
