Abstract According to the circuit theory and structure of the camera,the phenomena of
box camera caused by radiated electromagnetic field are described. By analyzing the
test method of radiated immunity and test phenomena, the improving means were
suggested to enhancing the camera's protective capability against the radiated
electromagnetic interference. Finally, the test results could meet the standard
requirements.
