Issue Details

Which submodule of a multi-module instrument shares and receives the trigger signals on the PXI Backplane?

Solution

To locate this information you need to take look at the documentation of the multi-module instrument for example the PXIe-5667. If you look through the PXIe-5667 Theory of Operation you can find the description of all individual modules. Also, here you can find the block diagrams which depict if the individual module manages the trigger sharing functionality. Indicators for this are the PXI_CLK100, the PXI_Trig lines, and the front panel PFI connectors.
