Signal connections to the NI PCI-6052E board

The NI PCI-6052E board has a counter-timer that is used to record an internal time base and x-ray counts from the proportional counter detector, and sixteen analog inputs which are used to record signals from the segmented silicon detector.

As noted in Sec. 8.1, the NI PCI-6052E receives its STARTSCAN input from the output of Multiplexer 2. The programmable internal time base is internally routed to General Purpose Counter input GPC0, and the proportional counter pulses are wired to input GPC1. A total of 14 analog inputs are routed from a DB25 input connector to NI PCI-6052E analog inputs in the scheme described in Table 8.4, and two further analog inputs are routed from BNC connectors to the last two analog inputs of the NI PCI-6052E. Notes on how to specify what analog inputs are associated with what signal are in Sec. 13.1.1.

Table 8.4: Pin assignments for the DB25 connector from the segmented silicon detector, and the analog inputs of the NI PCI-6502E multifunction board. Note that the ordering of analog inputs on the PCI-6502E does not have to follow the above table if an alternative wiring scheme is easier to lay out on the printed circuit board. The selection and ordering of analog inputs can be rearranged by software to compensate for some other ordering, as described in Sec. 13.1.1.
