Broadband electromagnetic measurement
Data recorded by the Institute of Atmospheric Physics, Prague, Czech Republic
in collaboration with
Laboratoire d’Aérologie OMP/CNRS/UPS Toulouse, France in the frame of the SOLID-PREVALS (Space-based Optical LIghtning Detection - PREparation, VALidation and Support) project.
During these measurements we test instrumentation which was developed
by the Institute of Atmospheric Physics for the TARANIS spacecraft project.
Broadband HF analyzer BLESKA (5 kHz - 37 MHz), a clone of the IME-HF analyzer for TARANIS, is connected to the SLAVIA sensor (Shielded Loop Antenna with a Versatile Integrated Amplifier) to detect the E-W horizontal component of the magnetic field fluctuations. The loop surface is 0.23 m2, the maximum amplifier gain is 47 dB. The maximum sensitivity of the recording system is 6 nT/s/√Hz, corresponding to 1 fT/√Hz at 1 MHz.
