The Agilent/National Instruments E1482B is a C-size, 1-slot VXIbus Extender module that bridges external controllers to VXI mainframes via MXIbus connectivity. This register-based module enables multiple VXI mainframes to operate as a unified system and supports daisy-chain configurations for multi-mainframe test architectures. The E1482B includes Interrupt and Timing Extension (INTX) functionality, delivering extended CLK10, programmable trigger lines, seven VXIbus interrupt lines, and system control signal extensions (SYSFAIL*, ACFAIL*, SYSRESET*).
