      <Description>E2 : The Förster probe experiment E2 is a three component-vector magnetometer. Its purpose is to 
continuously observe the interplanetary magnetic field in a frequency range up to 4 Hz. Thereby certain 
phenomena are to be analysed as a function of the distance from the sun e.g. the spiral structure and 
discontinuities. The measurement ranges are ± 100 nT and ± 400 nT. The resolution is ± 0.2 nT and ±
0.8 nT respectively.

For accurate measurements of the zero offset of each sensor the component parallel to the spinaxis can 
be flipped by 90°. Depending on telemetry format and bitrate the digital data are fed into a time average 
computer or directly connected to telemetry. A shock identification-computer triggers the S/C core 
memory in case of discontinuities with variations of the ambient magnetic field magnitude.

The Förster probe experiment E2 is a three-axe vector magnetometer. It is used for the continuous 
observation of the interplanetary magnetic field in a frequency range from 0 to 4 Hz. This will be 
investigated phenomena such as the spiral structure and discontinuities as a function of the distance 
from the Sun. The measuring ranges are ± 100 nT and ± 400 nT with a resolution of ± 0.2 nT or ± 0.8 nT. 
The component that is parallel to the axis of the spin, to perform precise zero point provisions of each 
sensor is rotated 90 degrees. Depending on format and bit rate digital data pass through an average 
computer or directly to the telemetry. A shock wave identification computer triggers the S/C core memory 
in the presence of discontinuities with magnetic field variations.

magnetometer.
