The Keysight/Agilent/HP E1302A is a 20-slot B-Size VME/VXI mainframe that serves as a modular instrumentation platform for integrating and testing VXI modules in demanding data acquisition and control applications. The mainframe accommodates B-size VXI modules with VME/VXI P1 and P2 row B backplane connectors and includes dedicated Slot 0 for command module functions and resource management.
