The Keysight E1403C 1- or 2-slot VXI carrier adapts A- or B-size VXI modules for use in al C-size VXI mainframes. P1, which is the only connector available, is a fully buffered extension. The E1403C provides slave-only capability and cannot be used in Slot 0 or with bus masters. The standard module is 1-slot wide; Option 010 is 2 slots wide, however, it only connects to the backplane on the left-most slot. Any number of adapters can be used in a Keysight VXI mainframe.
Many (but not all) VME cards can be adapted for use in C-size VXI mainframes using this module if they meet VXI mechanical and electrical restrictions. However, this is not a supported configuration.
