EMI testing on space systems - Use of FFT based measuring receivers for more speed, more insight and better reliability

Presented by Jens Medler, Product Manager, EMC Standards, Rohde & Schwarz and Maria Jiménez Lorenzo, EMC Test Engineer, INTA (National Institute for Aerospace Technology)

The use FFT-based measuring receivers is motivated by reducing the scan time by several orders of magnitude and to get more insight due to the possibility of applying longer measurement times. Comparison measurements on a nanosatellite were performed using conventional EMI receiver and FFT-based time-domain scanning technique.
