Source and measure, all in one unit
Before semiconductor devices and other electronic components can undergo commercial deployment, they must be characterized under a variety of environmental and functional testing to ensure conformity to specifications. Traditional benchtop testing involving a pair of digital multimeters and power supplies is often cost-prohibitive and time-consuming. A standalone, highly accurate, and highly functional device would be best suited to handle these applications. The source measure unit (SMU) provides:
Integration
- SMU's combine the functionality of several devices including digital multimeters, power supplies, current sources, ohmmeters, and function generators into a compact, standalone device
- Can be used as a storage device for data recording and transferring or as part of a larger test system
Accuracy
- Source and measure hundreds of volts to all the way down to the microamp range, without losing resolution or speed
Functionality
- Seven modes of operation for any situation including VS/IM, VS/VM, IS/VM, IS/IM, VS, IS, and VS/IM or IS/VM*
- Special software for performing I/V curve tracing
- A host of specialized functions for semiconductor testing including built-in and custom sweeps, ramps, and pwm.

The GS610 is made up of a programmable current and voltage source, a voltmeter, and an ammeter. Each function can be combined into numerous operation modes.
The GS820 is a highly accurate and highly functional 2-channel programmable DC voltage/current source that incorporates voltage/current generation and measurement function.
The GS200 is a low voltage/current DC source with high accuracy, high stability, and high resolution.
Yokogawa's instruments go beyond conventional options. They are highly accurate, highly functional with programmable voltage/current source that incorporates voltage/current generation for a broader application.

Source measure units are versatile devices that can precisely source, as well as monitor voltage and current. Because of this, there are numerous applications where these devices find use cases.
Source measure units combine the best features of power supplies and digital multimeters and have numerous applications ranging from battery simulators, semiconductor characterization, and efficiency testing on power electronics.
After a disastrous 2009, the large publicly held test companies enjoyed booming business in 2010.
