Description

Keithley 2401 - SourceMeter SMU Instrument (20 V, 1 A, 20 W)

Power: 20 W
Channels: 1
Max Current Source/Measure Range: 1A
Max Voltage Source/Measure Range: 20V
Measurement Resolution (Current / Voltage): 1pA / 100nV

Keithley’s Series 2401 Source Measure Unit (SMU) Instruments are 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 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 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 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.

Legacy Products and Suggested Alternatives

The 2401 SourceMeter SMU Instruments in this datasheet are classified as “Legacy Products”. They have been succeeded by Keithley’s newer 2401 Series Graphical SourceMeter SMUs with improved and greater performance. For new applications and designs, Keithley recommends you consider using the newer graphical models. The table provides a list of suggested graphical models for new applications and designs.

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 operate 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 applications, 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.

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 500 μs 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

Integrate with switching systems for fast, multipoint testing

The instruments in the SourceMeter family offer wide versatility, so they make great solutions for a variety of applications in many industries. For seamless integration in fast multipoint testing applications, combine a SourceMeter instrument with a Keithley switch system.

Test semiconductor devices
Test circuit Protection devices
Test optoelectronic components
Use for accelerated stress testing

Preparing engineering students to turn ideas into reality

Keithley SourceMeter SMUs are excellent tools to teach students the concepts of Ohms Law and I-V characterization for lab exercises to better understand how electronic devices behave and are used. SMUs give students the experience they need so they are prepared to meet the industry standards.

Combines the power of 5 instruments in one
Simplifies the teaching lab bench
Useful in graduate research

Instrument Control Start-up Software

KickStart Instrument Control/Start-up Software enables users to start making measurements in minutes without programming. In most cases, users merely need to make some quick measurements, graph the data, and store the data to disk for later analysis in software environments such as Excel. KickStart offers:

Configure and control up to four SMU instruments for DC or Pulsed I-V test in either the same app, same project, or a combination of the two.
Create tests by mixing any of these SMU instruments: 2401 Graphical Series, 2401 Standard Series (DC only), 2600B Series, 2651A, 2657A, and 6430 SourceMeter® SMU (DC only) instruments.
Differentiate SMU instrument channels and their measurement data using labels that are relevant to your device or module.
Native X-Y graphing, panning, and zooming; screenshot capturing of graphs.
Spreadsheet/tabular viewing of data; export data for further analysis.
Annotating of tests; save test setups.
GPIB, USB 2.0, Ethernet compliance.

Voltage Limit

Bipolar voltage limit (compliance) set with single value. Min. 0.1% of range

Overshoot

<0.1% typical (1mA step, RL = 10kO, 20V range for Model 2400, 2401, 2410, 2420, 2425, 2430), (10V range for Model 2440)

NOTES
1. 2400, 2401, 2410 Only: Specifications valid for continuous output currents below 105 mA. For operation above 105 mA continuous for >1 minute, derate accuracy 10%/35 mA above
105 mA.
2. Full operation (1 A) regardless of load to 30°C (50°C for 2420 and 2440). Above 30°C (50°C for 2420 and 2440) ambient, derate 35 mA/°C and prorate 35 mA/Ω load. 4-wire mode. For current sink operation on 1 A, 3 A, or 5 A 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, 1 µA to 100 mA range, accuracy is: 2400, 2401: ±(0.15% + offset*4). 2410, 2420, 2440: ±(0.5% + offset*3). For 1A range, accuracy is: 2400, 2401: ±(1.5% + offset*8). 2410, 2420, 2440: ±(1.5% + offset*3).
4. 10 A range only in pulse mode. Limited to 2.5 ms 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 200 mV, 1 A, 10 A ranges, add 0.05%. For 0.01 PLC, add 0.05% of range to offset specifications, except 200 mV, 1 A, 10 A 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. 2400 only.

Source I Mode, Manual Ohms

Total uncertainty = I source accuracy + V measure accuracy (4-wire remote sense).

Source V Mode, Manual Ohms

Total uncertainty = V source accuracy + I measure accuracy (4-wire remote sense)

6-wire Ohms Mode

Available using active ohms guard and guard sense. Max. Guard Output Current: 50 mA (except 1 A range). Accuracy is load dependent. Refer to White Paper below for calculation formula: “Obtaining More Accurate Resistance Measurements Using the 6-wire Ohms Measurement Technique.”

Guard Output Impedance

NOTES
1. Speed = Normal (1 PLC). For 0.1 PLC, add 0.005% of range to offset specifications, except 200 mV, 1 A, 10 A ranges, add 0.05%. For 0.01 PLC, add 0.05% of range to offset specifications, except 200 mV, 1 A, 10 A ranges, add 0.5%.
2. Accuracies apply to 2- or 4-wire mode when properly zeroed.
3. Manual ohms only – except 2420, 2440 for 2 Ω range and 2400, 2401, or 2410 for 200 MΩ range.
4. Source readback enabled, offset compensation ON. Also available on 2410, 2420, and 2440 with similar accuracy enhancement.
5. In pulse mode, limited to 0.1 PLC measurement.
