The Slope Box Extension (SBX) unit contains a power board and "pickoff card" along with an optional Raspberry Pi computer. As a whole, the SBX is there to handle much of the signals and processing between the detectors and the greater data acquisition system. The power board of the SBX provides all necessary power to the detector from a single source (48VDC), and allows a single detector and its SBX to be run entirely from one PoE (power over ethernet) port, enabling a detector to operate by itself. Meanwhile, the pickoff card converts signals from the detector to go to the digitizer. Understanding the SBX on a hardware level can be understood by observing the functions of the pickoff card.
These electronics replace ALL utility of the VXI system while providing additional functionality previously unavailable.
EPICS Interface for Slope Box
The Raspberry Pi contains an EPICS database allowing users to read and write process variables (PVs). The Slope Box PVs include detector controls and monitoring (HV, Temps, etc.), and the SBX Pickoff PVs include control for signal processing functions (DC offset, gain range, Preamp Reset Clamping, etc.).
