to induce a functional disturbance
Electromagnetic interference (EMI)
Based on a simple application running on the product (toggling two LEDs through the I/O
ports), the product is monitored in terms of emission. This emission test is in line with the
norm SAE J 1752/3 which specifies the board and the loading of each pin.
