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
thermocouple, BNC, LEMO
™
(B Series), and MIL-Spec connectors
Note PCI Express users should consider the power limits on certain SCC modules
without an external power supply. Refer to the device specifications, and the

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.
