Signal source for electromagnetic interference test of display devices

A signal source, comprising:

• a housing capable of attenuating an electromagnetic signal, the housing having a window portion which is made of glass with metal mesh or glass coated with a metal layer so as to preserve integrity of the housing to authenticate the interference signal radiated by the signal source;
• a parameter receiving module located within the housing and configured to receive related parameters of an interference signal required for testing Electromagnetic Interference radiation emission of a display device, wherein the signal parameters required for testing the display device received by the parameter receiving module pass the window portion wirelessly from outside of the signal source;
• a signal generating module located within the housing and configured to generate a the interference signal required for Electromagnetic Interference radiation emission of testing the display device based on the parameters received by the parameter receiving module;
• and
• an output interface located on the housing and configured to output the signal for testing Electromagnetic Interference radiation emission of the display device generated by the signal generating module to the display module device.
