This data set contains wave electric
field amplitudes measured at four different frequencies by the Pioneer Venus
Orbiter Electric Field Detector. The four frequencies are 100 Hz, 730 Hz,
5.4 kHz, 30 kHz. The frequency filters are narrow-band, with a 30% bandwidth.
Thus wave intensities are given in V2/m2/Hz. The filters are
continuously active, but data are only provided at a rate determined
by the spacecraft telemetry rate. The wave antenna is oriented
perpendicular to the spacecraft spin axis, and so the wave instrument
measures only wave fields in the spacecraft spin plane.
Spin modulation of naturally occurring signals can be used to
obtain two dimensional wave field information. The wave antenna
is a small Y-shaped structure, with effective separation of 0.76
meters. The spin phase of the effective dipole is included
within the high resolution data set for each of the channels, which
are sampled at different times.
