The Plasma Wave Receiver on Voyager consists of both a 16-channel spectrum analyzer covering the range of 10 Hertz to 56.2 kiloHertz and a wideband waveform receiver which returns the waveform of waves in the frequency range of 40 Hertz to 12 kiloHertz. The spectrum analyzer provides data on a continual basis with a maximum temporal resolution of one spectrum per 4 seconds. The waveform receiver returns 4-bit samples of theelectric field measured at a rate of 28,800 samples per second.
Because of the very high data rate, the waveform samples must be transmitted in the same manner as the Voyager imaging information. At Jupiter, some 10,000 48-second waveform frames were obtained. At Saturn, Uranus, and Neptune, the number of frames obtained was very small due to the lower telemetry ratesavailable at the greater distances of those planets.
