Themis - Instruments - The search coil antennas cover the frequency bandwidth from 0.1 Hz to 4 kHz. The Noise Equivalent Magnetic Induction (NEMI) of the search coil antennas and associated pre-amplifiers are not larger than 0.76pT/vHz at 10 Hz, 0.08pT/vHz at 100 Hz and 0.022pT/vHz at 1kHz. - Themis-Particpation Française
