The Slope Box Extension

SBX contents

The Slope Box Extension (SBX) unit contains a power board and "pickoff card" along with an optional Raspberry Pi computer. These electronics replace ALL utility of the VXI system while providing additional functionality previously unavailable. The power board of the SBX provides power to the detector, while the pickoff card converts signals from the detector to go to the digitizer. As a whole, the SBX is there to handle much of the signals and processing between the detectors and the greater data acquisition system. Understanding the SBX on a hardware level can be understood by observing the functions of the pickoff card.

EPICS Interface for Slope Box

The Raspberry Pi contains an EPICS database allowing users to read and write process variables (PVs):

• The Slope Box for detector controls and monitoring (HV, Temps, etc.)
• The SBX Pickoff for control of signal processing functions (DC offset, gain range, Preamp Reset Clamping, etc.)
