SCC

SCC is a front-end signal conditioning system for M 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
•
Low-profile/portable—Integrates well with other laptop computer measurement
•
technologies
High bandwidth—Acquire signals at rates up to 1.25 MHz
•
Connectivity—Incorporates panelette technology to offer custom connectivity to

Programming Devices in Software

National Instruments measurement devices are packaged with NI-DAQmx driver software, an
extensive library of functions and VIs you can call from your application software, such as
LabVIEW or LabWindows™/CVI™, to program all the features of your NI measurement
devices. Driver software has an application programming interface (API), which is a library of
VIs, functions, classes, attributes, and properties for creating applications for your device.
