Signal Conditioning Options
SCXI
SCXI is a front-end signal conditioning and switching system for various measurement devices,
including X 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.
Note (NI 6346/6349/6356/6358/6366/6368/6374/6376/6378 Devices)
Simultaneous MIO (SMIO) X Series devices only support controlling SCXI in
parallel mode.
Note (NI PXIe-6386/6396 Devices) PXIe-6386 and PXIe-6396 devices do not
support SCXI. For more information about special considerations for these devices,
go to ni.com/info and enter the Info Code smio14ms.
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
SCC
SCC is a front-end signal conditioning system for X Series plug-in data acquisition devices. An
SCC system consists of a shielded carrier that holds up to 20 single- or dual-channel SCC
modules for conditioning thermocouples and other transducers. SCC is designed for small
measurement systems where you need only a few channels of each signal type, or for portable
applications. SCC systems also offer the most comprehensive and flexible signal connectivity
options.
System features include the following:
• Modular architecture—Select your measurement technology on a per-channel basis
• Small-channel systems—Condition up to 16 analog input and eight digital I/O lines
