MiST - 4 Channel Multi Sensor Test Unit

The Paragraf Multi Sensor Test Unit (MiST) provides a self-contained, turn-key solution for the easy configuration and operation of up to four Graphene Hall Sensors (GHS) for a wide range of applications.

The array of configuration functions that MiST offers results in the best-achievable acquisition chain for magnetic field measurement using Paragraf GHS.

Windows-based software is provided for the easy setup and use of the system, with an optional set of software libraries for advanced configurations.

Through the software application, operators can dial in a specific, constant current supply to each individual GHS ranging from 100 nA to 5 mA.

Optimisation functions occurring before the digitisation and transfer of the magnetic field data to the PC (data collection rate up to 20 kHz) include:

• pre-amplification
• removal of offset readings from sensors
• switching (spinning-current method) function to remove pink (1/f) noise, and any remaining offset components

Includes a test probe - a general purpose magnetic field sensor probe designed for use in conjunction with the Paragraf Multi Sensor Test unit (MiST): it provides high sensitivity measurement of magnetic fields with a strongly linear response across a broad temperature range.
