Popis: The present work deals with electromagnetic compatibility (EMC) investigations in the field of electric propulsion (EP). A semi-anechoic chamber (SAC) was set up to perform EMC tests with thrusters under operating conditions. The facility includes a semi-anechoic room and a vacuum tank. The measurement electronics currently have an upper frequency limit at 18 GHz. Initial measurements were done operating a Pulsed Plasma Thruster (PPT) to familiarize with the electronic systems. The same device under test (DUT) was investigated in a reverberation chamber (RVC) to obtain comparative results which showed good agreement. Furthermore, the anechoic chamber shows satisfactory initial measurement characteristics, which will be further tested and improved in the future. Characteristics such as chamber pressure, base noise show realistic values. The next steps are to perform measurements on radio-frequency ion thrusters (RIT) including peripherals and cabling.
