The Parker Solar Probe, PSP, Digital Fields Board, DFB, is responsible for conditioning, digitization, and processing signals from the five voltage sensors and four search coil magnetometers, SCM, over a frequency range from DC to approximately 60 kHz, as well as production of a calibration signal delivered to the SCM. These nine analog inputs are processed by the DFB into twenty five digital data streams, which are then used to produce a range of time domain and spectral domain data products.
