The WAVES instrument is a joint effort of the Paris-Meudon Observatory, the University of Minnesota, and the Goddard Space Flight Center (NASA).
The sensors are : (1) three electric dipolar antenna systems supplied by Fairchild Space (two are coplanar, orthogonal wire dipole antennas in the spin-plane, the other a rigid spin-axis dipole) and (2) three magnetic search coils mounted orthogonally (designed and built by the University of Iowa). After preamplification, the sensor outputs are routed to the analysis electronics, consisting in a low frequency (DC - 10 kHz) FFT receiver, a broadband (4 kHz - 256 kHz) multi-channel analyzer designed principally to study the electron thermal noise, two dual radio receivers covering the band 20 kHz to 13.825 MHz, and a time-domain waveform sampler (sampling to 120,000/s). The experiment is controlled by a central microprocessor (DPU) which can be used in flight to reconfigure the sensor outputs and to maximize the science return for the bit rate and power allotments that are available. A DC/DC power converter is also part of the electronics stack.

The web page includes the data from the two Radio Receivers RAD1 and RAD2 whose the characteristics are the following ones :

 Band 1 (RAD1) Inputs : Ex+Ez, Ez Frequency range : 20 kHz - 1,040 kHz No. channels : 256 Bandwidth:3 kHz Sensitivity : 7 nV/Sqrt(Hz)
 Band 2 (RAD2) Inputs : Ey+Ez, Ez Frequency range : 1.075 MHz - 13.825 MHz No. channels : 256 Bandwidth : 20 kHz Sensitivity : 7 nV/Sqrt(Hz)
