Software Description

The USB Magnetometer includes a GUI for data logging the field readings from the sensor in units

of Oersted and displaying those readings in analog, digital, and graphical formats. The data in the

graphical display can be logged or output to a csv file, which is compatible with most spreadsheet

programs and easy to import into analysis software. The display can be configured in several data

viewing modes or in a mode to control operation of the acquisition electronics. The software allows

a user to set the resolution, sample rate, filtering, averaging, trigger mode, linearization, and to

perform sensor calibration. The GUI also contains a built in terminal emulator for sending and

receiving low-level commands to and from the probe, which is useful for programming

non-standard configurations and also for debugging commands to be used in custom software

applications.

The USB Magnetometer was designed to enable users to interface it with their own custom

programs by sending and receiving text commands using a COM port. This is useful for writing

data acquisition and data acquisition system control programs, such that the user can input data

directly to a program without needing to export it from the USB Magnetometer GUI to a csv file.

The COM port commands are fully documented in the user manual, and they may be tested using

any terminal emulator program or the built in terminal emulator.
