Keysight / Agilent / HP E1490A VXI Breadboard Module

The E1490A is a C-size, 1-slot VXI breadboard module that enables integration of custom circuitry directly within VXI-based instrumentation systems. Designers use this module to prototype and develop specialized measurement and control solutions without redesigning the entire system architecture. The module provides a dedicated breadboard area for user-defined circuits and communicates with the VXI controller through a register-based interface.
