With virtual instruments, we also can automate a testing procedure, eliminating the possibility of human error and ensuring the consistency of the results by not introducing unknown or unexpected variables. Virtual instruments represent a fundamental shift from traditional hardware-centered instrumentation systems to software-centered systems that exploit the computing power, productivity, display, and connectivity capabilities of popular desktop computers and workstations.
These devices offer a wide range of data acquisition capabilities at a significantly lower cost than that of dedicated devices. What makes one different from the other is their flexibility and the fact that you can modify and adapt the instrument to your particular needs.
Traditional instruments also frequently lack portability, whereas virtual instruments running on notebooks automatically incorporate their portable nature. When dealing with a large project, engineers and scientists generally approach the task by breaking it down into functional solvable units.
Ecosystem[ edit ] Due to the longevity and popularity of the LabVIEW language, and the ability for users to extend its functions, a large ecosystem of third party add-ons has developed via contributions from the community.
A virtual instrument provides all the software and hardware needed to accomplish the measurement or control task.
Rather than programming graphics and all custom attributes from scratch, you can simply drag-and-drop these objects onto the instrument front panels.
Embedded systems at one time meant stand-alone operation, or at most interfacing at a low level with a real-time bus to peripheral components.
It is not only versatile but also extremely cost-effective. As the pace of innovation has increased, so too has the pressure to get new, differentiated products to market quickly.
Virtual instruments are compatible with traditional instruments almost without exception. They can define how and when the application acquires data from the device, how it processes, manipulates and stores the data, and how the results are presented to the user.
Virtual instrumentation software typically provides libraries for interfacing with common ordinary instrument buses such as GPIB, serial or Ethernet.
As new computer technologies emerge, you can easily migrate your applications to new platforms and operating systems. Virtual instrumentation software platform, LabVIEW, includes the ability to scale from development for desktop operating systems, to embedded real-time systems to handheld personal digital assistant targets, to FPGA-based hardware, and even to enabling smart sensors.
Virtual Instrument and Traditional Instrument A traditional instrument is designed to collect data from an environment, or from a unit under test, and to display information to a user based on the collected data.
The ease with which you can accomplish this division of tasks depends greatly on the underlying architecture of the software. Applications such as wireless communication and high-definition video impact these technologies relentlessly.
With virtual instruments, we also can automate a testing procedure, eliminating the possibility of human error and ensuring the consistency of the results by not introducing unknown or unexpected variables. But as control needs become more complex, there is a recognized need to accelerate the capabilities while retaining the ruggedness and reliabilities.
Both require one or more microprocessors, communication ports for example, serial and GPIBand display capabilities, as well as data acquisition modules.Virtual Instrumentation With LabVIEW.
