Chamber for an EMC/EMI precompliance test

The Financial Case for an EMI/EMC Pre-Compliance Test Solution

Tuesday, April 20, 2021
Failing EMI compliance testing can be a design engineer’s worst nightmare. Additional compliance testing costs, external lab testing, debug engineering time, and in some cases, board spins can add significant costs and time delays to your project. Unfortunately, for companies new to EMI/EMC, estimating compliance testing cost can be somewhat challenging. In this blog, we’ll provide information on …

PCIe Gen 5 Testing Challenges – Spread Spectrum Clocking (SSC) Thursday, June 3, 2021
Spread Spectrum Clocking (SSC) is a highly effective technique utilized to reduce electromagnetic interference or EMI. PCI Express 5.0 System designers use this tool to reduce the adverse effects on adjacent circuits and to pass FCC or other regulatory body requirements for EMI emissions. Manifestations of EMI can result in performance degradation and loss of digital information. Validation of …
How to Measure a MOSFET I-V Curve
How to Measure a MOSFET I-V Curve Thursday, May 27, 2021
One of the best ways to ensure a MOSFET is functioning properly and meets specifications is to determine its characteristics by tracing I-V curves. There are a number of output characteristics requiring I-V tests; you can derive gate leakage, breakdown voltage, threshold voltage, transfer characteristics, and drain current all by simply tracing I-V characteristics and verifying the device is …
