What is an SMU? |
The Keithley Source Measure Unit (SMU) is also known as Keithley SourceMeter®. It is an instrument that can precisely source voltage or current and simultaneously measure voltage and/or current. It integrates the capabilities of an individual power supply, a digital multimeter (DMM), a current source, and an electronic load into a single, tightly synch |
Overview |
|
A Source Measure Unit (SMU) precisely sources and simultaneously measures voltage and/or current. Most well-established test applications include IV characterizing plus testing semiconductors and non-linear devices and materials. These applications perform voltage sweep and/or current sweeps across any of the 4-quadrant operating regions (positive and negative DC/pulsed source or sink and measurement) of an SMU. 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:

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. |

2606B High Density SourceMeter
|
|
The 2606B High Density System SourceMeter (SMU) Instrument offers four 20-watt SMU channels in a 1U high form factor chassis. As manufacturers need to optimize plant floor space and reduce test time and costs, the 2606B improves density by 3 times, increases throughput, and minimizes the need to add additional racks of test equipment. This SMU is the perfect solution for production testing of Laser Diodes, LEDs, 2- and 3-terminal semiconductors and much more. |
