Source/measure Units

Source/measure Units

Transcat offers source measure units in various categories, from precision to application specific. A source and measurement unit (SMU) is a device that supports testing applications, including those that demand high accuracy and high resolution capabilities. The units essentially combine the functionality of a DMM with a precise power supply, while also offering excellent low current operations. An SMU can precisely source voltage or current to a device under test or development, while simultaneously measuring voltage and/or current. These simultaneous capabilities often equate to faster testing processes. An SMU is the smart solution when low-level voltage, current, and resistance are needed for functional tests and electronics profiling. Unit applications range from design validation to manufacturing, and SMUs are frequently used within the semiconductor and electronics industries.


Reviewing a Precision Source-Measure Unit


To order a Source/Measure Unit, you will need to know what test(s) the device complements, such as a Functional Test or a Battery Drain Analysis. Also determine if you want a unit with two- or four-quadrant operations. The characteristics of a precision source measure unit will cover specifications within the following categories: 


  • Output ratings: Voltage, Current, Power
  • Output voltage ripple and noise
  • Programming accuracy
  • Measurement accuracy


SMUs for Testing Challenges


The source measure units from Keysight Technologies are built to solve testing challenges. They are used with the brand’s modular power system to deliver advanced sourcing and measurement capabilities. Keysight’s N6781A model supports the optimization of power consumption and the maximizing of battery life. It offers the functions and features to accurately capture power consumption in battery-driven components.
