Identify New Failure Effects with DGS Tests

Dynamic gate stress tests help engineers qualify SiC and GaN devices.


  • Identify and simulate failure effects that are not visible with traditional testing methods
  • Align test procedures more closely with real applications and provide precise statements to your customers
  • Utilize fast voltage shifts to stimulate fault mechanisms at the gate
  • In-situ measurements determine relevant parameters to show the long-term effects of dynamic gate stress on the gate oxide
  • Fully automated tests cover the extended requirements from the industry and provide detailed reporting for further data analysis

​NI SET DGS Power Semiconductor Test System​

  • The DGS test system converts the extended requirements from industry into automated dynamic tests, emphasizing flexibility to quickly adapt to changing requirements.

  • In addition to the stimuli, the DGS test system also offers numerous in-situ measurements to determine relevant parameters in a defined time period. 

  • In-situ measurements show efficiently the long-term effects of dynamic gate stress on the gate oxide and enable you to provide precise statements to your customer.
