SCXI

SCXI is a front-end signal conditioning and switching system for various
measurement devices, including M Series devices. An SCXI system
consists of a rugged chassis that houses shielded signal conditioning
modules that amplify, filter, isolate, and multiplex analog signals from
thermocouples or other transducers. SCXI is designed for large
measurement systems or systems requiring high-speed acquisition.
System features include the following.
• Modular architecture—Choose your measurement technology
• Expandability—Expand your system to 3,072 channels
• Integration—Combine analog input, analog output, digital I/O, and
switching into a single, unified platform
• High bandwidth—Acquire signals at high rates
• Connectivity—Select from SCXI modules with thermocouple
connectors or terminal blocks
