Source Meters

What are Source Meters?

Source measures are referred to as source meter units or source measure units, abbreviated as SMU, and they provide users with efficient current and voltage-sourcing measuring capability. Many new types of source measures are embedded in outstanding features from leading brands such as Keithley and Keysight Technologies. A source meter is very handy for measurements that have low resistance embedded in the current, so the source meter helps you save time and money. Since you do not need additional instruments and can accommodate fewer people, it is specifically ideal for places where space is a necessary element. 

What is a Source Measure Unit / Source Meter (SMU)?

We now know that a Source Meter Unit (SMU) is an instrument that can source or measure voltage or current. The features of a source meter are identical to those of a (DMM) Digital Multimeter, including power supply, current source, electronic load, and pulse generator. As a source meter, an SMU digital multimeter includes all its characteristics. Compared to a typical semiconductor, the source meter is a more precise and adaptable measurement tool with a larger range of applications.

What are the functions of a Source Meter (SMU)?

  • Current-voltage source
  • Pulsar
  • Current precision measurement and true current measurement.
  • Current resistance

The source meter distributes the current voltage and lets them measure current flow the same as benchtop power devices. However, in terms of precision measurement, 

Our wide range of source meters offers customers an excellent choice of existing media, such as the Keithley range, which distributes 1 to 4 channels and some other output power options.

Source Meter (SMU) Measurement Options Are Available

  • The measurement from 1 Ω.
  • Source current comes in varied sizes from 1 μA (nA).
  • Output power from 20 W to 1000 W.
  • Source voltage ranges from 20 mV to 1000 V.
