Description
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). For EAC and EHF the sampling rate is the same as the ROI, but the cadence is 16 s and 2048 s respectively.
