The instrument automatically chooses one of eight ranges in which to operate, the four lowest full-scale ranges being +/-4, +/- 14, +/-42, and +/- 146 nT. The precision of measurement is 1/256 of the full-scale field values (0.016, 0.055 nT, etc.). The absolute accuracy is limited by knowledge of the spacecraft magnetic field, which is presently known to better than 0.1 nT. The time resolution corresponds to three triaxial samples per second at 1024 bit/s . The magnetometer contains a three- channel spectrum analyzer which is connected to the search-coil sensor of the plasma- wave investigation.
