Overview

They typically involve high accuracy and high resolution, in addition to highly synchronized sourcing and measurement requirements.

An application that requires the integration of individual power supply, digital multimeter (DMM), current source, and/or electronic load will find using an SMU saves setup time, saves software development time, saves rack and bench space, increases throughput and achieve reliable and repeatable results 5 ½ and 6 ½ digits of resolution over a wide selection of power envelopes.

SMUs are gaining popularity in new technology research, development and manufacturing, such as:

• nano-scale devices and materials, carbon nanotube structures, graphene
• organic semiconductors
• printed electronics
• small-geometry low-power devices
• high power materials, silicon carbide (SiC), gallium nitride (GaN) devices, power MOSFETs,
• high brightness LEDs, solid state lighting systems
• optoelectronics, laser diode test systems
• battery charging and discharging characterization
• power management ICs
• circuit protection modules
• solar cells and panels
• DC-DC converters

The 2460 and 2461 Sourcemeters have an identical TouchScreen Interactive graphical user interface.

Digitising Capabilities of the 2450, 2460 & 2461 SourceMeters

This video demonstrates the digitising capabilities of the Keithley 2461 SourceMeter Source Measure Unit (SMU) using a high brightness LED.

Creating Battery Discharge Profiles for Simulating Batteries with Keithley's 2450 SMU & 2281 Battery Simulator.

This video demonstrates how to create a model for a battery that can be used in a battery simulator. A 2281 Battery Simulator emulates a battery for this demonstration and a 2450 SourceMeter discharges the "battery" and creates the battery model. The 2450 could be substitiuted by a 2460 or 2461 SourceMeter.

How To Connect Series 2600B SMU Instrument to Your Mobile Device Using Wi Fi

The Keithley IVy mobile app is the fastest and easiest way to perform current-voltage (I-V) characterization, troubleshoot your device under test (DUT), and share the measurement results with others. It allows you to visualize, interact with, and share measurement results without programming.

IVy is currently compatible with Keithley Series 2600B SourceMeter® Source Measure Unit (SMU) Instruments This video details how to connect the Series 2600B SMU Instrument to an iPhone or iPad using Wi-Fi. The 2600B and the mobile device must be connected to the same wireless network. In this video, this is achieved by connecting the LAN port of the Series 2600B to a wireless router.

• Low priced Options (non-Touchscreen)

2470 High Voltage Touchscreen SMU

Keithley 2400 Series SMU instruments offer four-quadrant precision voltage and current source/load coupled with measurement now on a touchscreen user interface.

These instruments can simultaneously source and measure current from 10 fA to 10 A pulse and/or voltage from 100nV to 200V, for 1000W pulse and 100W DC total power.

2600B Series SourceMeters

• High speed embedded programming

• Single of dual channel options

• Source up to 10A pulse, 200V, 200W

Keithley’s Series 2600B System SMU instruments are the industry standard current-voltage source and measure solution for highly automated production test applications.

Both dual- and single-channel models tightly integrate a precision power supply, true current source, DMM, and electronic load with pulse generating capabilities. Plus, TSP® technology runs complete test programs for automated system applications, and TSP-Link® technology enables daisy-chaining up to 64 channels for high volume parallel test.

2601B-PULSE System SourceMeter 10 µsec Pulser/SMU

• Ideal for bench or production

• Pulse 10 A @ 10 V down to 10 μs

• 1 μs, 18-bit sample rate

2606B High Density SourceMeter

• Four channels in 1U form factor
  Stackable;
