        "Description": "PSP FIELDS Digital Fields Board (DFB), Single Ended Voltage data. The DFB is the low frequency (< 75 kHz) component of the FIELDS experiment on the Parker Solar Probe spacecraft [1]. For a full description of the FIELDS experiment, see [2]. For a description of the DFB, see [3].DFB continuous waveform data consist of time-series data from various FIELDS sensors. These data have been filtered by both analog and digital filters [3]. The Level 2 data products contained in this data file have been calibrated for (i) DFB in-band gain, (ii) DFB analog filter gain/phase response, (iii) DFB digital filter phase response, and (iv) the search coil preamplifier gain/phase response (when applicable). Calibrations for the FIELDS digital filter gain response have not been implemented, but the required convolution kernel is provided in this file.  It was decided not to apply the FIELDS digital filter gain response to the L2 data because this can introduce non-physical power at high frequencies when the non-corrected signal is dominated by noise. This effect should be examined carefully when determining spectral slopes and features at the highest frequencies. Calibrations for the FIELDS voltage sensor preamplifiers have not been implemented, as the preamplifier response is flat and equal to 1 through the DFB frequency range.  Corrections for plasma sheath impedance gain and antenna effective length have not been applied to the voltage sensor data (these corrections will be applied in Level 3 DFB data), therefore units for all voltage sensor quantities are Volts.  Units for all magnetic field quantities are nT.The Level 2 data products contained in this data file are in spacecraft coordinates (e.g. x,y,z) and in sensor coordinates (e.g. dV12, dV34 for voltage measurements, and u,v,w for the search coil magnetometer). Time resolution for the DFB continuous waveform data can vary by multiples of 2^N.  During encounter (when PSP is within 0.25 AU of the Sun), cadence for the DFB continuous waveform data is typically 256 samples/NYsecond [2].  References: 1. Fox, N.J., Velli, M.C., Bale, S.D. et al.
