National Instruments C Series Modules

The manufacturer National Instruments has numerous series organized by the type of instrument, one of which is the C Series. This series is comprised of Voltage Output Modules, Universal Analog Input Modules, CAN Interface Modules, Digital Modules, Current Output Modules, Counter Input Modules, Temperature Input Modules, Current Input Modules, Digitizer Modules, Voltage and Current Input Modules, Sound and Vibration Input Modules, Strain/Bridge Input Modules, LIN Interface Modules, Voltage Input Modules, Relay Output Modules, and more. It is also worth noting that several specifications for a C Series system are determined by the modules and other specifications are determined by the backplane. Other specifications can even be based on the configuration of the system. The NI C Series is designed for the CompactDAQ and CompactRIO platforms.

Understanding Specifications Part 2

To prevent interference on receiving apparatus, for example, audio and TV receivers or computer systems, signals generated in the line supply and the radiated electromagnetic field of radio frequency from electrical equipment may not exceed certain limits. For this, the IEC makes recommendations. A special committee of the IEC, the CISPR (International Special Committee on Radio Interference), has published several definitions concerning measuring sets and measurement procedures for the various types of interference-producing equipment.
