Measuring only 3x3x0.9 mm, the MagVector™ MV2 is a powerful magnetometerAn instrument to measure magnetic flux density (B) or magnetic field intensity (H). on a chip: three orthogonal Hall sensors measure (Bx,By,Bz); the “spinning current” technique minimises noise, offset and the Planar Hall EffectA popular magnetometer technology, using a semiconductor plate. One injects current on one axis of the plate and measures a...; a built-in temperature sensor permits temperature compensationHall magnetometers are sensitive to temperature, so they may include a temperature sensor that allows the instrument to compensate the...; a programmable-gain amplifier provides measurement ranges from 0.1 to 30 T; and built-in ADCs and SPI (Serial Peripheral Interface) provide a digital interface in addition to an analog one.

A signal pin selects between the analog or digital interface. In analog mode, configuration options such as the measurement rangeThe range of a probe is defined by the minimum and maximum field strength it can measure. On an instrument,... are selected using controlAn NMR-controlled field is one whose strength is monitored by NMR.
