Introduction
============

The [*[in-situ]{}*]{} measurements of coronal heating, solar wind acceleration, and energetic particle transport made by NASA’s Parker Solar Probe (PSP) will likely answer many fundamental questions relating to the heliosphere and astrophysical plasmas [@Fox2016]. The FIELDS instrument on PSP provides [*[in-situ]{}*]{} measurements of the electric and magnetic fields [@Bale2016] required to achieve the principal objectives. The measurements made by FIELDS are complemented by [*[in-situ]{}*]{} measurements of the solar wind and coronal plasma through the Solar Wind Electrons Alphas and Protons investigation; energetic particles through the Integrated Science Investigation of the Sun ; as well as white light images from the Wide-Field Imager for Solar Probe .

Accomplishing the scientific objectives of PSP requires [*[in-situ]{}*]{} observations of magnetic and electric fields over a wide bandwidth and large dynamic range. FIELDS measures electric field and potential fluctuations ranging from DC-19.2 MHz with a diverse combination of survey mode waveform, burst mode waveform, and spectral observations made by the FIELDS Radio Frequency Spectrometer , Digital Fields Board , and Time Domain Sampler (TDS) [@Bale2016].
