The Keysight E1407A C-size, 1- or 2-slot carrier adapts A- or B-size VXI module for use in al C-size VXI mainframes. The P1 and P2 extensions are fully buffered. A ribbon cable allows isolation of the outer rows of P2 for VME applications. The E1407A 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.
