Abstract
A direct electrical connection is provided between transmission line segments of a data slipring and a data acquisition system. A transformer may be provided between the data acquisition system and the transmission line segments for correcting an impedance mismatch between the slipring and the electrical connection. A method of connecting the data slipring with the data acquisition system includes providing a controlled impedance electrical cable between the transmission line segments and the data acquisition system.
