The CompactDAQ platform expands to now offer over 30 measurement modules and new, free data-logging software. This overview will highlight all that is new with CompactDAQ and C Series modules since the first launch.

During the process of debugging and validating a digital system, a common task is the acquisition of digital waveforms. A logic analyzer is a tool that allows numerous digital waveforms to be acquired simultaneously. The acquisition can be clocked internally, or the System Under Test (SUT) can provide the sample clock. A logic analyzer also supports multiple triggering schemes to determine when data is acquired. The NI 655x has many features that make it ideal for digital waveform acquisitions. These include flexible memory sizes, voltage levels, and input impedances, advanced acquisition timing options, diverse acquisition triggering choices, powerful data visualization programming features, and extensive expansion and integration capabilities.

One of the most common data acquisition applications is simply logging acquired data to disk or a database for future analysis. Most National Instruments data acquisition (DAQ) devices are shipped with FREE data-logging software. Depending on your data-logging application requirements, you may need additional functionality. This article introduces the three levels of data-logging software for use with National Instruments DAQ devices – NI LabVIEW SignalExpress, NI LabVIEW SignalExpress LE and NI LabVIEW.

Zigbee is a wireless standard for personal area network (PAN) sensor monitoring and control. Learn how National Instruments Alliance Partner SeaSolve has developed a test suite including transmit (Tx), receive (Rx) and compliance testing for Zigbee. In this application note, we will describe test methodologies and techniques for each type of testing.

Today’s Teaching Trends: Hands-on Learning In order to mitigate the challenge of declining enrollment, Educators are now incorporating hands-on, experiential learning techniques into the classroom. By giving students the opportunity to interact with real-world signals and compare the simulation results, educators find that students learn concepts much better. LabVIEW SignalExpress, an interactive environment built on the industry-leading NI LabVIEW Graphical System Design platform helps make hands-on, experiential learning possible for students across multiple disciplines, from biomedical engineering to aerospace engineering and across multiple years, from freshmen to senior with its powerful, interactive, step-by-step approach. Some of the benefits of using NI LabVIEW SignalExpress in the classroom as are follows
