Schematic representation of the sweep control system. The system consists of a superconducting magnet, a bipolar power supply, a field-mapping unit and a home-built broadband NMR probe. All components are controlled by a PC, running LabView. Communication between the computer and the FMU is accomplished via TCP/IP. The sweep-coil current is controlled by an analog voltage supplied by the DAC-card of the FMU.
