    Abstract
    ========
 
      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.
