Simplify Your Current-Voltage Measurements

Go from 4 Instruments to
1 Source Measure Unit

Watch the video to see how a Keithley source measure unit (SMU) tightly integrates a power supply, digital multimeter (DMM), electronic load, and current source.

Learn more about common DC measurements
that require source and measure
.

For separate DMM measurements and Power Supply applications please see our full range of Keithley products here.

A SMU = DMM + Power Supply + Electronic Load + Current Source.
Best supported by Google Chrome or Firefox browser.

Get our measurement kits to learn more about these common DC measurements.

And source and measure current and voltage without wrestling a DMM, power supply, electronic load, and current source.

I-V Characterization for
2-terminal Devices

thumbnail
  • Sweep source voltage and measure current across a wide range over many decades (10–11A to 1A)
  • Generate an I-V curve without multiple instruments, programming or synchronization

I-V Characterization & Curve Tracing for 3-terminal Devices

thumbnail
  • Generate multiple I-V curves on a MOSFET for curve tracing
  • Eliminate multiple instruments, synchronization and programming


Resistivity

  • Source/sink high current and measure voltage and current on low resistance devices
  • Save bench space and minimize test set up


Power Efficiency

thumbnail
  • Easily determine the input and output power of devices under test (DUTs)
  • Save bench space and minimize test set up
