Abstract : The emission of radio frequency radiation from electrical discharges was studied in the spectral region from 10 to 1000 megacycles per second. The investigation was conducted to obtain fundamental information on the mechanisms governing production of rf radiation from discharges and to determine which parameters significantly influence the emission characteristics. This information was acquired in order to devise the most effective technique for detecting and isolating failures and intermittents in electronic systems and components by interpreting the rf noise associated with them. To establish the extent of their influence upon rf emission, the following parameters were investigated; (1) environmental factors such as temperature, humidity, type of gas, and pressure; (2) electrode parameters such as material, configuration, and potential; (3) external radiation such as x-rays, ultraviolet radiation, and magnetic fields. The report concludes with a number of suggested approaches for exploiting the results of the investigation for checkout of electronic and electrical equipment. (Author)
