Getting Started with SCXI

Introduction to SCXI Systems

National Instruments SCXI (Signal Conditioning eXtensions for Instrumentation) provides a flexible and powerful platform for data acquisition and signal conditioning. This system bridges the gap between sensors and your computer, enabling precise measurement and control for a wide range of applications.

SCXI systems can be configured in various ways, serving as front-end signal conditioners for plug-in DAQ devices, or as external DAQ systems connected via parallel or serial ports.

Key SCXI Components

An SCXI system typically comprises the following core components:

• SCXI Chassis: The main enclosure housing SCXI modules, providing power and communication pathways.
• SCXI Modules: Specialized cards for signal conditioning, analog input/output, and digital I/O.
• Terminal Blocks & Accessories: Devices for connecting sensors and signals to SCXI modules.
• DAQ Devices: Data acquisition hardware (e.g., DAQCards, PCI boards) that interfaces with the SCXI system.
• Software: Application development environments and driver software (like NI-DAQ) for controlling the system.
