Once an instrument driver has been downloaded, the instrument driver VIs will be located on the Instrument Drivers palette. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. An instrument driver is a set of software routines that control a programmable instrument. Once the measurement is complete, the Close VI is called which performs an instrument error query and terminates the software connection to the instrument. Don’t be afraid of experimenting. The Utility VIs might also include other custom instrument driver VIs that perform operations such as calibration or storage and recall of setups.

Generally, you need to call the Close VI only once at the end of an application or when you finish communication lahview an instrument. Make sure that for each successful call to the Initialize VI, you use a matching Close VI to avoid maintaining unnecessary memory resources. Examples include VIs for reading a measured value or waveform and VIs for downloading waveforms or digital patterns to a source instrument. Back to Top 2. When all of these settings are set and the VI is executed the results will be displayed in the Measurements array indicator.

You can use an instrument driver for a particular instrument as is.

Using LabVIEW driver for Agilent A – Discussion Forums – National Instruments

The Utility 34401z perform a variety of operations that are auxiliary to the most often used instrument driver VIs. Open a blank vi. After you call these VIs, the instrument is ready to take measurements or to stimulate a system.


Both of these drives are supported by Agilent and come complete with example code for common tasks. Overview of Instrument Drivers An instrument driver is a set of software routines that control a programmable instrument.

The best way is to open the sub-vi which appears to lavview what you want to do and run it. You can create instrument control applications and systems by programmatically linking instrument driver VIs on the block diagram. Learn more about our privacy policy. Don’t be afraid of experimenting. The following figure shows this palette and some of the VIs and subpalettes that are shipped with it.

How to Use an Instrument Driver in LabVIEW Tutorial

I download directly from Agilent’s website. Message 5 of 7. Generally, you need to call the Lwbview VI only once at the beginning of an application. This site uses cookies to offer you a better browsing experience.

Look at what you are measuring and see if it is albview. It would be extremely useful to show how to modify portions of instrument drivers for other use. Try the link below: I’m not sure about instructions, but if you installed the driver and opened the library, you will get sub-vi’s which have a particular application purpose.


Has a 3 Application Examples and a “Getting Started” one which labviwe get you on your way. The Action VIs – initiate or terminate test and measurement operations, such as arming the trigger system or generating a stimulus. An instrument driver is a set of software routines that control a programmable instrument.

Les Hammer Complete Test. Message 1 of 7.

Instrument drivers simplify instrument control and reduce test program development time by eliminating the need to learn the programming protocol for each instrument. Numerous Configuration VIs can exist, depending on the particular instrument. Message 3 of 7.

However, LabVIEW Plug and Play instrument drivers are distributed with their block diagram source code, so you can customize them for a specific application.

Your on your way to success Hope this helps. The fastest way to get up and running with your instrument driver is to open one of the pre-built examples. Each routine corresponds to a programmatic operation such as configuring, reading from, writing to, and triggering the instrument. The Data VIs- transfer data to or from the instrument.
