TL;DR: The Cassini radio and plasma wave investigation is designed to study radio emissions, plasma waves, thermal plasma, and dust in the vicinity of Saturn as mentioned in this paper, which is the only spacecraft that can perform radio and plasmas measurements.

TL;DR: The STEREO/WAVES instrument as discussed by the authors was designed to measure the three components of the fluctuating electric field from a fraction of a hertz up to 16 MHz, plus a single frequency channel near 30 MHz.

TL;DR: Radio emissions from Saturn showed that the radio rotation period is now 10 hours 45 minutes 45 ± 36 seconds, about 6 minutes longer than measured by Voyager in 1980 to 1981, and many intense impulsive radio signals were detected from Saturn lightning during the approach and first orbit.

TL;DR: The Voyager 1 planetary radio astronomy experiment detected two distinct kinds of radio emissions from Saturn, one of which is strongly polarized, bursty, tightly correlated with Saturn's rotation, and exhibits complex dynamic spectral features somewhat reminiscent of those in Jupiter's radio emission.

TL;DR: While crossing the ring plane at a distance of 2.88 Saturn radii, the spacecraft detected an intense noise event extending to above 1 megahertz and lasting about 150 seconds, interpreted to be a consequence of the impact, vaporization, and ionization of charged, micrometer-size G ring particles distributed over a vertical thickness of about 1500 kilometers.
