This is a slave screen of the main Digitizer Control screen. The currently selected Digitizer/Fpga (and hence Detector/Crystal/Segment) is shown. This can only be changed from the main Digitizer Control screen. If you do this then return here and Reload the window. The possible signal sources for each inspection line depends on which digitizer/fpga (or detector/crystal/segment) are selected. The pull-down menus are updated accordingly. As a Signal Source is changed using the menus the updated value is written to the hardware. Note: The Logic inspection lines cannot be disabled.
