In this study, measurements inside the fuselage of an unmanned air vehicle (UAV) are conducted using a novel double-loaded loop probe. The characterization and evaluation of electromagnetic interference (EMI) within VAVs is a main research topic and requires state-of-the-art measurement methodologies. The developed probe is capable of obtaining accurate measurements as commercial reference E-Field broadband probes, introducing new advantages based on the reduction of the probe's electronics and the availability of the full time-domain data. Allowing to compute simultaneously the electric and the magnetic field and to measure high-amplitude electromagnetic pulses. The laser-probe works together with multi-channel full-time domain system computing the electromagnetic fields using an oscilloscope. Regarding the double-loaded loop probe characterization and validation, it has been carried out by comparing the results with different validation methods, like Feature Selective Validation Method and the Integrated Error against Logarithmic Frequency.

A CM noise reduction method by adding a terminal ground filter between the cable ground and chassis is proposed. The noise reduction performance of the terminal ground filter is estimated with a simplified circuit model. The proposed filter is implemented in a small PCB, and applied to a 3.3kW power system of an air conditioner. The reduction of the CM CE noises by applying the terminal ground filter is experimentally validated.

This paper investigates jitter degradation of highspeed I/O when RF power sources, such as smartphone, are in proximity to the I/O link. The jitter is increased by as high as ~200% when a 500-mW LTE antenna is 3 cm away from the transmission line at 831 MHz and may cause failure of the high-speed link. An analytic model is developed to capture the jitter behavior at various RF amplitudes and clock slew-rates. A good agreement among the model, simulation, and measurement is obtained at various frequencies and with a measured LTE signal. This study may help to predict the jitter degradation due to adjacent RF power and may be more critical to I/O interfaces with higher speed.

This paper deals with the investigation of EM interferences between the FM radio services and a power converter installed on a special purpose vehicle of the fire department. While sporadic interference signals cannot be observed reliably with conventional EMC measurements, real time spectrum measurements are used for the identification of the interference source as well as the coupling path. The investigation finally point out, that a power converter is responsible for the EM interferences radiated by an additional onboard power system. Since the interferences cover a frequency range up to 80 MHz, they are received by the 4 m band antenna and thus disturb the FM radio service due to front door coupling. Furthermore, other radio devices near the command vehicle (e.g. a handheld radio set) will be also disturbed.
