Spectral analysis is performed on signals from three detectors: a pair of long electric-field antennas, a short electric-field sensor and a search coil, both of which are mounted on one of the experiment booms (Fig. 6). Electric-field fluctuations between 20 and 100000 Hz are measured in 16 frequency channels once per second at 1024 bit/s. Cometary dust particles hitting the spacecraft or the electric antennas caused detectable outputs similar to those detected when Voyager passed through Saturn's ring-plane.
