2 Setup

To implement the PHY performance validation tests, it is important to have the most noise-free environment possible, without external electrical noise sources or interferences that could affect the final results.

Important: Power supplies of computers, battery chargers, light dimmers, low-consumption lights, or USB isolators produce noise in the mains that can affect the final results of the PHY performance validation test. Make sure that the setup is noise free to get the most reliable results.
