Abstract: National Instruments® (NI) pioneered virtual instrumentation more than 25 years ago with the introduction of LabVIEW — fully graphical development system. On several platforms they offer software products that deliver the proven productivity gains of virtual instrumentation. Over twenty years at the Department of Measurement and Control VSB — Technical University of Ostrava the students have taken advantage of the flexibility and open development model to solve applications in a wide variety of cases. Computer laboratories equipped by flexible hardware components make education and research cheaper and more productive and improve the way students learn. Rather than focusing on sometimes tedious methods of software development for gathering data, educators and students can focus on results and concepts. Students still learn methodology, but spend the majority of their time executing their experiments instead of building them.

TL;DR: The real-time education and research platform is presented with seven experiments that provide the various concepts of these courses for different state-of-the-art wireless and digital communications techniques such as signal detection, data modulation, frequency, phase offset estimation, etc.
Abstract: The paper presents the real-time education and research platform as an effective means for describing wireless and digital communications courses with Wi-Fi standards. To this end, a Real-Time Wi-Fi Laboratory platform, called RTWiFi-Lab is designed and implemented as part of these courses using NI USRP 2921 and LabVIEW. Laboratory experiments of these courses give benefits for utilizing a hardware platform since these experiments greatly facilitate the understanding of significant effects introduced by real-time receivers. Hence, this platform is presented with seven experiments that provide the various concepts of these courses for different state-of-the-art wireless and digital communications techniques such as signal detection, data modulation, frequency, phase offset estimation, etc. The RTWiFi-Lab has been considered to provide computer engineering undergraduate students and qualified graduate students with the basic introduction to wireless and digital communications concepts in a short time at Kocaeli University, Turkey.

TL;DR: The VI generates a Routh-Hurwitz array for analyzing system stability based on obtaining the characteristic D (s) equation and is able to identify situations where there is a space or row of zeros within the array.
Abstract: This paper describes the design of a virtual instrument (VI) to analyze stability in control systems implemented in LabVIEW virtual instrumentation software. The VI generates a Routh-Hurwitz array for analyzing system stability based on obtaining the characteristic D (s) equation and is able to identify situations where there is a space or row of zeros within the array. Furthermore, the VI shows the graphical location of the poles and zeros of the transfer function in closed loop, the graphical system response to a unitary step input and peak time, overshoot, settling time and peak value of the step response. Finally a case study on a DC-DC buck type converter operating in continuous and discontinuous conduction is reviewed.

TL;DR: A "learn-by-doing" approach to acquiring the computer-based skills used in daily experimental work, the text's unique organization makes it suitable as either a short introduction to LabVIEW or a guide to more in-depth programming.
Abstract: Hands-On Introduction to LabVIEW for Scientists and Engineers takes a "learn-by-doing" approach to acquiring the computer-based skills used in daily experimental work Ideal as a course textbook or a self-study supplement, the text explores practical programming solutions for carrying out interesting and relevant projects Readers--who are assumed to have no prior computer programming or LabVIEW background--will begin writing meaningful programs in the first few pages Instructors adopting the book as a classroom text can easily choose the desired depth of coverage for their courses The first four chapters focus on the fundamentals of LabVIEW programming and the basics of computer-based experimentation using a National Instruments data acquisition (DAQ) device; these chapters provide the instructional materials necessary for a three-week introduction to LabVIEW-based data acquisition A full-featured course that uses most of the text's chapters will bring students to an intermediate skill level in computer-based data acquisition and analysis Features *Flexible modular structure The text's unique organization makes it suitable as either a short introduction to LabVIEW or a guide to more in-depth programming *Easy-to-implement Express VIs enable introduction of data acquisition in early chapters *"Do It Yourself" projects at the end of each chapter Each project poses an interesting "real-world" problem and loosely directs readers in applying the chapter's material to find a solution *Homework problems at the end of each chapter A wide selection of homework-style problems allows interested students to test their understanding and further develop their computer-based experimentation skills

TL;DR: The latest methods for evaluation of modulation parameters using new generation test systems based on PXI modular platform and graphical programming in LabVIEW are demonstrated, concentrating on the most widely used modulation technique - QPSK.
Abstract: This paper describes modern software based flexible measuring systems for analysis of digitally modulated systems. The latest methods for evaluation of modulation parameters using new generation test systems based on PXI modular platform and graphical programming in LabVIEW are demonstrated. Authors concentrate on the most widely used modulation technique used in radio communication systems - QPSK. To achieve the best results, different measurements were performed, like measurement in the time domain, spectral measurements, vector diagram, and constellation diagram. Many results for definition of communication system quality were obtained like r (rho), DC offset, phase error, quadrature skew, IQ gain imbalance, bit error rate (BER), frequency deviation, burst timing measurements, modulation error ratio (MER) and error vector magnitude (EVM).
