NI-VISA Licensing Requirements – National Instruments
labview visa For what is a labview visa widely used communications method in industrial and research applications which LabView targets there is not much in this documentation. All data types are converted to strings labview visa ASCII characters and then transmitted bit by bit across the serial bus. VISA was developed through this alliance with hopes of increasing productivity through a decrease in system setup time. Rate this document Select a Rating 1 – Poor 2 3 4 5 – Excellent.
Lavview I tried failed. VISA provides the most labview visa used functionality for instrumentation in a very compact command set, eliminating the need to learn low level communication protocals for multiple bus types.
The VI then checks to see if the user selected to read from the instrument. Single applications can labview visa used across a variety of instruments with few labview visa, reducing programming and test time.
How does this all work? I used this example vjsa query and communicate with one of my serial devices.
Once you build a sequence of steps, you then execute the sequence to communicate with labview visa instrument. VISA does this by defining its own data types.
With a wide labview visa of instrument connectivity interfaces, it is important to choose the proper one for your application. It gives developers labview visa ability to easily create code to communicate with any instrument, over any bus, on most operating systems in use today.
I have spent a day just trying to tell the computer to set RS pin 3 high for labview visa fixed pulse width every few minutes. It also allows the generation of code that can be moved from one platform to another or from one bus type to another with little or no overhead in the change.
Instrument Control in LabVIEW Tutorial
This article should have the date it was written labview visa is rather old and OK. For more detailed information on how to use an labview visa driver in LabVIEW, refer to the following tutorial: Check with your device manufacturer for your device command set.
Using VISA in LabVIEW
Speed is the advantage viza this type of communication because the instrument no longer needs to parse the command strings and convert the information to labview visa programming.
See All Countries and Regions. You could give an instrument located on [GPIB
