TestScale System Components

In a TestScale system, a backplane is connected to your PC through USB and then populated with up to five measurement I/O or power modules and one required core module.






ni compactdaq chassis are designed for extreme environments

Built with your functional test needs in mind, TestScale offers an integrated-system simplified backplane that features USB connectivity and include five slots that can be used to mix and match I/O to fit various applications and one slot reserved for the required core module. Backplanes are offered in two variants to fit the deployment needs of any application, whether you require a rack-mount or in-fixture setup.


Technician in factory setting

From interactively capturing and exploring your data to programming a fully automated measurement system, seamless software integration lets you tailor tests to your needs. We designed TestScale to work with TestStand™, SystemLink™, and programming environments such as LabVIEW™ to help you meet development requirements and spend your time on what matters most. Since TestScale hardware also uses the powerful NI-DAQmx driver, you can program it with the language of your choice. The TestScale Soft Front Panel (SFP), a software add-on for InstrumentStudio, can help you configure and execute measurements.


Technician in factory setting

From the moment you unbox your hardware, through deployment and life-cycle maintenance, NI is here to help you get started quickly and operate efficiently.

Overcome your challenges with:

  • Repair Services 

  • Life-Cycle Services 

  • Configuration 

  • Calibration

TestScale’s small form factor allows us to design a board that provides PCB routing directly from the instrument to the DUT. This is a cost-effective and scalable design, ideal for high volume test.
