This data set is a collection of ASCII files of eight different types for frequency spectra of 10-minute average and peak intensity values of electric and/or magnetic intensity from three sensors in the URAP experiment, namely the Plasma Frequency Receiver (PFR), the Radio Astronomy Receiver (RAR), and the Wave Form Analyzer (WFA). The PFR, RAR, and WFA each provide averaged and peak value frequency spectra for electric field intensities in each 10-minute interval. The WFA also provides frequency spectra for magnetic fields. PFR and RAR frequency spectra are determined from measurements on the X antenna of the URAP instrument in units of microvolt/Hz^0.5 for each frequency channel (0.61 - 32.82 kHz for the PFR and 1.25 - 940.0 kHz for the RAR). The WFA measures frequency spectra with a two-axis sensor aligned to the Y and Z spacecraft axis for frequency response in this data set at 0.22 - 448.0 Hz in units of microvolts/ Hz^0.5 for electric fields and 10^-15 Telsa/Hz^0.5 for magnetic fields. The data set includes a user guide document in ASCII text format. Details on the PFR, RAR, and WFA sensors are available in Stone, R.G., et al., "The Unified Radio and Plasma Wave Investigation," Astron. and Astrophys. Supp. Ser., 92, 291-316, 1992.
