Signal Generators, Sources and Supplies

Easily generate standard and custom waveforms, calibrate instruments with precision, and achieve high accuracy results with our high performance generators and sources.

Yokogawa offers a range of devices including source measure units, function/arbitrary waveform generators, and AC/DC calibrators and standards. Our sources and generators can be used for general purpose standalone applications or as core components in an integrated test and measurement platform.

Trusted by engineers for their accuracy, intuitive operation, and reliability, Yokogawa generators and sources simplify the testing process by integrating source and measurement into a single unit, allowing for quick and easy characterization of semiconductor devices, clamp-on testers, panel meters, power meters, batteries, and dataloggers .

A Source Measurement Unit (SMU) is a flexible test instrument which is capable of both sourcing and measuring voltage and/or current at the same time.

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.

Yokogawa's Function Generators easily generate basic, application specific and arbitrary waveforms.

The simple, standalone solution for calibrating clamp on testers, power meters, multimeters, current transformers, and analog and digital panel meters.

  • Yokogawa digital multimeters with high accuracy, stability, and linearity
  • Simple verification
  • Large-scale troubleshooting

DC Calibrators are versatile devices that span a wide range of applications


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

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 ...
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 ...

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


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.


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 ...


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 ...


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 ...


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 ...
