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. ## Technical Specifications • Form Factor: C-size, 1-slot VXI module • Interface Architecture: Register-based communication with VXI controller • Power Distribution: Onboard power supplies designed to accommodate user-added circuitry; voltage and current ratings are user-defined per custom circuit requirements • Module Family: Part of the Keysight/Agilent/HP 75000 Series ## Key Features • Full breadboard area for custom electronic component integration • Direct VXIbus connectivity for seamless chassis integration • Register-based control architecture for deterministic system communication • Supports user-defined power supply configurations for specialized applications ## Typical Applications • Custom signal conditioning and measurement circuits • Prototype development and validation within production instrumentation • Specialized control interfaces and data acquisition modules • Application-specific measurement extensions to standard VXI systems ## Compatibility & Integration The E1490A operates within any VXI chassis that supports standard VXIbus architecture. The module is compatible with VXIplug&play and SCPI programming standards, enabling straightforward integration into existing test software and control frameworks. Documentation includes technical manuals and datasheets covering installation, operation, and detailed specification information.
