Electric and Magnetic Field Probes (ONCH-TBF)

The electric and magnetic field probes (ONCH-TBF) on Aureol 3 measured the three components of the magnetic field at frequencies between 10 Hz and 16 kHz. The combined Soviet-French ONCH-TBF onboard instrument was designed to allow comprehensive measurements of both electric and magnetic wave fields. The measurements in real-time modes included 5-component wave-form data in the range 10 Hz - 1.5 kHz for 3 magnetic and 2 electric field components, or a wide-band mode in the range 10 Hz - 1.5 kHz, and several filter banks. In memory modes the data only from several filter-banks in the range from 10 Hz to 16 kHz were recorded. For further details, see Berthelier et al., Ann. Geophys., V. 38, N5, p. 643, 1982.

Aureol 3 上的电场与磁场探测器（ONCH-TBF）测量了磁场在10 Hz至16 kHz频率范围内的三个分量。该苏联-法国联合研制的ONCH-TBF机载仪器旨在实现电场与磁场波场的全面测量。实时模式下的测量包括10 Hz至1.5 kHz范围内的5分量波形数据，涉及3个磁场分量和2个电场分量，或10 Hz至1.5 kHz范围的宽带模式，以及多个滤波器组。在存储模式下，仅记录了10 Hz至16 kHz范围内的几个滤波器组的数据。欲了解更多详细信息，请参阅Berthelier等人在《Ann. Geophys.》第38卷第5期第643页，1982年的相关研究。
