The concept of a synthetic instrument is a subset of the virtual instrument concept. A synthetic instrument is a kind of virtual instrument that is purely software defined.
The main advantage virtual instrumentation provides the user is that it utilises commercially available technologies, such as the PC and the ADC in place of traditional hardware.
Software packages like National Instruments' LabVIEW and other graphical programming languages helped grow adoption by making it easier for non-programmers to develop systems.
What is Labview
Labview stands for “Laboratory Virtual Instrument Engineering Workbench”.
Produced by NATIONAL INSTRUMENTS
Graphical programming environment(G programming)
Powerful and versatile analysis and instrumentation software system for measurement and automation.
Advantages of LabVIEW
Graphical user interface
Drag and drop built-in functions
Modular design
Multiple high level development tools
Multi platforms
Reduces cost and preserves investment
Flexibility and scalability
Open environment
Visualization capabilities
Compiled language for fats execution
Object oriented design
Algorithm design
Major advantage
LabVIEW offers up to 10X development speed compared to other text based programming languages.
Also its built in functions for instrument control and data acquisition makes it a good choice for test and control applications.
