A Greater Measure of Conﬁdence

Keithley’s Series 2400 Source Measure Unit (SMU) Instruments

are designed specifically for test applications that demand tightly

coupled sourcing and measurement. All SourceMeter models pro-

vide precision voltage and current sourcing as well as measure-

ment capabilities. Each SourceMeter SMU instrument is both

a highly stable DC power source and a true instrument-grade

6½-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 instru-

ments 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, semiconduc-

tor, computer, automotive, and medical industries will find the

SourceMeter SMU 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 issues associated with using

multiple instruments. And, their compact half-rack size conserves precious “real estate” in the test

rack or bench.

Power of Five Instruments in One (IV Source, IVR Measure)

The tightly coupled nature of a SourceMeter SMU instrument provides many advantages over solu-

tions configured from separate instruments, such as a precision power supply and a digital multime-

ter. For example, it provides faster test times by reducing GPIB traffic and simplifies the remote pro-

gramming 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.

I-V Characteristics

All SourceMeter SMU 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 oper-

ate as a sink, dissipating power internally. Voltage, current, and resistance can be measured during

source or sink operation.

Automation for Speed

A SourceMeter SMU instrument streamlines production testing. It sources voltage or current while

making measurements without needing to change connections. It is designed for reliable operation

in non-stop production environments. To provide the throughput demanded by production applica-

tions, the SourceMeter SMU 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

automation hooks. Three basic sweep waveforms

are provided that can be programmed for single-

event or continuous operation. They are ideal for

I/V, I/R, V/I, and V/R characterization.

•Linear Staircase Sweep: Moves from the start

level to the stop level in equal linear steps

•Logarithmic Staircase Sweep: Done on a

log scale with a specified number of steps

per decade

•Custom Sweep: Allows construction of

special sweeps by specifying the number of

measurement points and the source level at

each point

•Up to 1700 readings/second at 4½ digits to

the GPIB bus

•5000 readings can be stored in the non-

volatile buffer memory

Built-In Test Sequencer

(Source Memory List)

The Source Memory list provides faster and

easier testing by allowing you to setup and

execute up to 100 different tests that run without

PC intervention.

•Stores up to 100 instrument configurations, each containing source settings, measurement

settings, pass/fail criteria, etc.

•Pass/fail limit test as fast as 500µs per point

•Onboard comparator eliminates the delay caused when sending data to the computer for analysis

•Built-in, user definable math functions to calculate derived parameters

Digital I/O Interface

The digital I/O interface can link a SourceMeter SMU 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

The digital I/O interface is available on all Series 2400 SoourceMeter

instruments except the Model 2401.

Trigger Link Interface

All SourceMeter SMU 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 SMU instrument with a Series 7000 Switching

System for a complete multi-point test solution. With Trigger Link, the

Series 7000 Switching Systems can be controlled by a SourceMeter SMU

instrument 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 elimi-

nates measurement errors and false product failures associated with con-

tact 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 SMU instrument 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: 2W, 15W, and 50W

•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 SMU instruments 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. 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 SMU instruments, making characterization of two, three,

and four terminal devices a snap.

NOTES

1. 2400, 2401, 2410 Only: Specifications valid for continuous output currents below 105mA. For operation above

105mA continuous 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/W 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, 2401: ±(0.15% + offset*4). Models 2410, 2420, 2425, 2430, 2440: ±(0.5% + offset*3).

For 1A range, accuracy is:

Model 2400, 2401: ±(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.
