The key system features are:
– Multiple Hall sensors provide high-precision, simultaneous 3-axis field measurements at multiple points.
– USB provides both system power and data communication.
– An optional thermal sensor allows for temperature compensationHall magnetometers are sensitive to temperature, so they may include a temperature sensor that allows the instrument to compensate the... or regulationA NMR-regulated magnet is an electromagnet whose field is measured by an NMR teslameter, which then closes the loop by....
– An optional low-noise voltage regulator provides optimal measurement stability.

The platform consists of:
Hardware:
– Magnetic field sensors: MagVectorTM MV2
– Microprocessor: Silicon Labs C8051F380
– Voltage regulator: Texas Instruments REG102
– Temperature sensor: Texas Instruments LM71CIMF
Firmware:
– Write and read SPI data to/from selected device
– Synchronise acquisitions
– Loop-back test of USB communication
– Retrieve hardware/firmware versions
– Get device information
– Read or write arbitrary data, e.g. calibrationDuring calibration, the instrument reading is compared to one or more references to verify its accuracy. The references themselves need... tables, to ROM
Software:
– LabVIEW API to access all firmware features
– MagVector MV2 register access
– Programming examples
