6-Hour Hands-On
Introduction to LabVIEW
© National Instruments Corporation 1 Introduction to LabVIEW Hands-On
Course Goals
• Become comfortable with the LabVIEW environment
and data flow execution
• Ability to use LabVIEW to solve problems
• LabVIEW Concepts
– Acquiring, saving and loading data
– Find and use math and complex analysis functions
– Work with data types, such as arrays and clusters
– Displaying and printing results
This is a list of the objectives of the course.
This course prepares you to do the following:
• Use LabVIEW to create applications.
• Understand front panels, block diagrams, and icons and connector panes.
• Use built-in LabVIEW functions.
• Create and save programs in LabVIEW so you can use them as subroutines.
• Create applications that use plug-in DAQ devices.
This course does not describe any of the following:
• Programming theory
• Every built-in LabVIEW function or object
• Analog-to-digital (A/D) theory
NI does provide free reference materials on the above topics on
ni.com.

The Virtual Instrumentation Approach
Virtual Instrumentation
For more than 25 years, National Instruments has revolutionized the way engineers and
scientists in industry, government, and academia approach measurement and
automation. Leveraging PCs and commercial technologies, virtual instrumentation
increases productivity and lowers costs for test, control, and design applications
through easy-to-integrate software, such as NI LabVIEW, and modular measurement
and control hardware for PXI, PCI, USB, and Ethernet.
With virtual instrumentation, engineers use graphical programming software to create
user-defined solutions that meet their specific needs, which is a great alternative to
proprietary, fixed functionality traditional instruments. Additionally, virtual
instrumentation capitalizes on the ever-increasing performance of personal computers.
For example, in test, measurement, and control, engineers have used virtual
instrumentation to downsize automated test equipment (ATE) while experiencing up to
a 10 times increase in productivity gains at a fraction of the cost of traditional
instrument solutions. Last year 25,000 companies in 90 countries invested in more than
6 million virtual instrumentation channels from National Instruments.

LabVIEW Graphical Development System
• Graphical Programming Environment
• Compile code for multiple OS and devices
• Useful in a broad range of applications
National Instruments LabVIEW is an industry-leading software tool for designing test,
measurement, and control systems. Since its introduction in 1986, engineers and
scientists worldwide who have relied on NI LabVIEW graphical development for
projects throughout the product design cycle have gained improved quality, shorter time
to market, and greater engineering and manufacturing efficiency. By using the
integrated LabVIEW environment to interface with real-world signals, analyze data for
meaningful information, and share results, you can boost productivity throughout your
organization. Because LabVIEW has the flexibility of a programming language
combined with built-in tools designed specifically for test, measurement, and control,
you can create applications that range from simple temperature monitoring to
sophisticated simulation and control systems. No matter what your project is, LabVIEW
has the tools necessary to make you successful quickly.

A single graphical development platform
Virtual Instrumentation Applications
Virtual instrumentation is applicable in many different types of applications, starting from design
to prototyping and deployment. The LabVIEW platform provides specific tools and models to
solve specific applications ranging from designing signal processing algorithms to making
voltage measurements and can target any number of platforms from the desktop to embedded
devices – with an intuitive, powerful graphical paradigm.
With version 8, LabVIEW scales from design and development on PCs to several embedded
targets from ruggedized toaster size prototypes to embedded systems on chips. LabVIEW
streamlines system design with a single graphical development platform. In doing so,
LabVIEW encompasses better management of distributed, networked systems because as the
targets for LabVIEW grow varied and embedded, you will need to be able to more easily
distribute and communicate between various LabVIEW code pieces in your system.
