For EAC and EHF the sampling rate is the same as the ROI, but the cadence is 16 s and 2048 s respectively. spase://SMWG/Person/John.W.Bonnell InstrumentLead CoInvestigator spase://SMWG/Person/David.M.Miles PrincipalInvestigator spase://SMWG/Person/Lan.Jain MetadataContact spase://SMWG/Person/Scott.Boardsen MetadataContact Electric Fields Instrument (EFI) https://doi.org/10.1007/s11214-025-01202-5 Electric field measurements with a sampling rate for EDC of 128 samples/s (ROI), 8 samples/s (BOR), EAC 2048 samples/s (ROI), electric field high frequency (EHF) 20e6 samples/s (ROI).
