The Agilent/Keysight E2251A is a C-size, single-slot VXI M-Module Carrier that provides cost-effective integration of specialized functionality into VXIbus systems. It accommodates up to six M-Modules, each with independent logical addressing, enabling tailored system configurations that optimize both cost and performance. The carrier manages the electrical and mechanical interface between the VXIbus backplane and installed M-Modules, handling VXI register configuration, I/O space and memory access, and interrupt handling. Fully programmable interrupts are available for each M-Module.
