Data Acquisition Hardware

System designers must architect modern data acquisition systems on building blocks that provide scalability to address a wide range of data rates and capacities at the lowest possible cost. Although the scale continues to move from Mbytes/sec to Gbytes/sec and beyond, the fundamental need for scalability remains rooted in the need to break high speed data sources into manageable chunks or streams that a system can independently record. System documentation is simplified by the software`s ability to automatically document functions created by objects and UserObjects. For example, the loading system uses the Trace Display object to generate an x-y plot, and the system solves for the point-slope equation y = mx + b, where b is the x-intercept (see Fig.

PC/104 also allows card modules to self-stack without backplanes or card cages, and has pin-and-socket bus connectors designed for high reliability in harsh environments. It is, essentially, a miniaturized version of the standard PC bus architecture. PCI expansion technology offers systems integrators a solution for architecting massively parallel PC-based systems that can provide both scalability for future requirements and tackle today’s toughest data acquisition requirements.

But in your selection process, you might have assumed that some of these features are standard in any device! There is no such thing as a standard feature that goes unmentioned in the product specification. But to start I need to know where I’m slow . I think there is a wealth of information to be learned from that. But the FDAU function is likely to evolve, as architectures become more integrated, more data is collected, and avionics systems are connected over high-speed networks.

But the complex and expensive hardware and software for data processing and image reconstruction would be located in a central facility capable of serving multiple remote sites. Local medical personnel would use cell phones to transmit unprocessed data gathered on-site to the central server. But if an application demands custom timing, triggering, or other functionality unavailable in the driver, the developer spends valuable time building or programming custom hardware.

Software development is done through a serial link compatible with TI development tools. Software interprets the readings to make the hard numbers digestible. After engineers review the readings, they better understand how to revise their design to meet specifications. Software controls each digital output by just one bit - setting the digital line high or low.

Software programs orchestrate all of the experimental control, data acquisition and analysis. Software can, for example, set the gain, offset and filters on computer-controlled signal conditioners and analog input and output channels. Software also measures the decay rate for the tone—the time it takes a note to fall from its maximum intensity to below 30 decibels. A third measurement produces wave diagrams for each tone.

Wireless technology extends NI data acquisition hardware and software technology to new distributed and portable measurement applications where wiring is difficult or cost-prohibitive. The flexibility of LabVIEW graphical programming and the ubiquity of Wi-Fi network infrastructure make it easy to incorporate wireless sensor measurements into new or existing PC-based measurement or control systems.
