Solar Wind Electron Analyzer, SWEA, Instrument Bias Voltage, V₀. The bias voltage sweep pattern was altered to reduce low energy electron contributions from unanticipated spacecraft-related secondaries. The voltage bias were originally swept from 1 eV to 2000 eV but the lower limit sweep voltage was later updated to 8 eV.
