Source Measure Units

Source and measure, all in one unit

Source measure units integrate the functionality of multiple devices, making them essential for semiconductor and electronic component testing. They combine digital multimeters, power supplies, current sources, ohmmeters, and function generators into one compact, standalone device.

Key Features of SMUs

  • Integration: SMUs offer data recording and transferring capabilities, usable as standalone devices or within larger test systems.
  • Accuracy: Capable of sourcing and measuring a wide range of voltages and currents with high precision.
  • Functionality: Seven operational modes and specialized software for I/V curve tracing and semiconductor testing.

Benefits of Using SMUs

  • Efficiency: Reduces the need for multiple instruments, saving time and cost.
  • Versatility: Supports various test modes and custom functions for detailed component analysis.
  • Reliability: Ensures accurate and repeatable measurements across different testing scenarios.

Applications of SMUs

Ideal for testing semiconductors and other electronic components, ensuring they meet commercial deployment specifications through thorough environmental and functional testing.

This lineup includes 3-slot and 9-slot frames equipped with trigger synchronization and remote-control functions.

This 2-channel modular SMU can source ±6 V / ±600 mA and sink ±6 V / ±200 mA or ±2 V / ±600 mA.


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.

  • Yokogawa source measure unit GS820
  • Precision SMU quick response for automated testing
  • High-speed communication improves productivity
  • Customizable to enable any test

The GS200 DC Voltage/Current Source Pulse Generator from Yokogawa Test&Measurement 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.

Application Note
Overview:

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. 

Overview:
  • Parametric characterization of DC-DC converters using source measure units
  • GS 610, 820
  • Purposes include stable power supply and providing stimulus to circuit to measure response
Overview:

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. 

Industries:
Overview:

After a disastrous 2009, the large publicly held test companies enjoyed booming business in 2010.

Overview:
No, the GS610 and the GS820 cannot be used solely as a DMM to measure only voltage. This is because the Sense terminal cannot be separated from the Output terminal on the instrument. The GS Series uses the Output ...
Overview:

The AC Power Input in all Yokogawa instruments is designed as a 3-pin connection (one of which is a GND pin). In some parts of the world, PCs are sold with AC power cables that are 2-pin. Often times this means the ...

Overview:
Unfortunately, we cannot upgrade a GS200 to add the /MON option. The GS series instruments, which includes the GS610 and GS820, cannot be retrofitted or upgraded with new options after the initial purchase. All ...
Overview:

The following attached document details the typical output noise of the GS200 Voltage / Current Source from DC to 20 MHz.

Overview:

This is a list of command mnemonics which can be used to describe the GS610 Source Measure Unit program pattern file.○:Setting has changed successfully△:Setting has been received but failed×:Setting has not been ...

Overview:

The GP-IB command of the GS200 DC Voltage / Current Source shares the same mode as the 7651. It can be switched to 488.2 mode.

Overview:

It is possible to connect multiple GS units in series/parallel connections to boost the maximum voltage/current, provded the values are within the range of maximum voltage/current of those limiters. To amplify the ...

Overview:

The GS610/GS820 Multi Channel Source Measure Unit output is insulated from the cover case. Therefore, if you want to amplify the output voltage more than 1 unit (or 1 ch) you must connect the system in series. If you want to increase the output ...
