The aims of the investigation were to perform an analysis of VLF electric fields at Venus and to elucidate the plasma interactions between the solar wind and the ionospheric or exospheric plasma. The role of plasma instabilities in modifying the heat flux from the solar wind and in thermalizing newly-born ions from Venus was also studied. A self-contained balanced V-type antenna with a differential preamplifier was employed to make the measurements. At the 512 bps satellite mode, one frequency scan per second was obtained. The Pioneer Venus plasma wave instrument has a self-contained balanced electric dipole (effective length = 0.75 m) and a 4-channel spectrum analyzer (30-percent band width filters with center frequencies at 100 Hz, 5.4 kHz, and 30 kHz). The channels are continuously active and the highest Orbiter telemetry rate (2048 bps) yields 4 spectral scans/s. The total mass of 0.55 kg includes the electronics, the antenna, and the antenna deployment mechanism. This report contains a brief description of the instrument design and a discussion of the in-flight performance.
