Measurement Principle
The EWO consists of three sets of receivers: EWO-EFD (Electric Field Detector), EWO-WFC/OFA(E) (Wave-Form Capture/Onboard Frequency Analyzer for Electric field), and EWO-WFC/OFA(B) (WFC/OFA for Magnetic field) [Sec.5 of Kasaba et al. (2020a)]. Those receivers observe waveforms and spectra in the frequency range from DC (very low frequency) to 120 kHz for the electric field and from 0.3 Hz to 20 kHz for the magnetic field. The EWO covers the frequency range of various plasma waves in and around the Hermean magnetosphere. The basic design is similar to that of the PWE EWO unit aboard the Arase PWE (Kasahara et al. 2018a; Kasaba et al. 2017).
