The diagram here shows a possible solution for an Archaeology Resistivity Meter
The blue central device shown here is effectively a small custom computer with the right hardware inputs and outputs for users to perform archaeology resistivity based tasks with the right software and (if desired) attachments such as a PC or tablet.
In this solution, the hardware can define the possible inputs and outputs and other resources such as processing capability. The software on the blue central device and any attached computer devices will implement the specific desired features and algorithms.
In other words, it can be considered to be a software-defined tool for archaeology (or other) tasks.
