Set-up for Testing Telecom Power Unit Immunity to Electromagnetic Fields

The modern telecommunications facilities depend on power units, which can be shut down suddenly by severe disturbances. A large number of disturbances can be attributed to radiated electromagnetic emissions. Emission testing has been relatively easy. The immunity of electronic equipment to RFI is expressed as maximum electric field strength that it can withstand. The paper describes the respective test set-up. Besides standard measuring equipment like RF generator and a power amplifier, a cell is needed in which well defined electromagnetic field is established The cell was used to test a DC/DC converter. The paper exhibits the test procedure.
