1–3–4 Countermeasures against EMC-related Issues
Generally it is very difficult to handle issues related to EMC. It may be time consuming and costly.
General countermeasures
Electromagnetic interference with other equipment
1) Electromagnetic interference may be alleviated by positioning other equipment far from the system.
2) Electromagnetic interference may be mitigated by changing the relative location (installation angle)
between the system and other equipment.
3) Electromagnetic interference may be eased by changing wiring locations of power/signal cables of other
equipment.
4) Electromagnetic influence may be reduced by altering the path of power supply for other equipment.
