The following figure shows this palette and some of the VIs and subpalettes that are shipped with it. Message 4 of 4. Message 2 of 7. The Initialize VI- the first instrument driver VI you call, establishes communication with the instrument. I don’t know which driver you are using, so it is difficult to send you an example.

Many instrument drivers have a VI Tree VI you can use to view the entire instrument driver hierarchy. From the block diagram you can see that the instrument is first initialized with the Serial Configuration and VISA resource name specified on the front panel.

An instrument driver is a set of software routines that control a programmable instrument.

Can I transfer 34401A or 34420A measured data to my PC without any programming?

Numerous Configuration VIs can exist, depending on the particular instrument. The Utility Agolent perform a variety of operations that are auxiliary to the most often used instrument driver VIs.

Look at what you are measuring and see if it is useful. The Configuration VIs- a collection of software routines that configure the instrument to perform the operation you want. The alternative to using the NI Instrument Driver Finder is to go directly to the Instrument Driver Network and search for your instrument driver there.


Instrument drivers simplify instrument control and reduce test program development time by eliminating the need to learn the programming protocol for each instrument.

I hope this helps! Message 7 of 7. Most Active Software Boards: The Data VIs- transfer data to or from the instrument.

The best way is to open the sub-vi which appears to be what you want to do and run it. These VIs include the majority of the agilet driver template VIs, such as reset, self-test, revision, error query, and error message. It would be extremely useful to show how to modify portions of instrument drivers for other use.

Message 2 of 4.

In this example, serial communication is used. Get acquainted with sub-vi’s.

How to Use an Instrument Driver in LabVIEW Tutorial – National Instruments

I download directly from Agilent’s website. Does anyone have advice on how to log the samples at recieved from the multimeter in relative time, continiously for defined period of time. Has a 3 Application Examples and a “Getting Started” one which should get you on your way. You can use an instrument driver for a particular instrument as is. Thank you for help! Feel free to write us at les. After you call these VIs, the instrument is ready to take measurements or to stimulate a system.


Once an instrument driver has been downloaded, the instrument driver VIs will be located on the Instrument Drivers palette. If aggilent are not very concerned with high speed aka you can wait for the data to be written to diskyou can just add the “Write to delimited Spreadsheet” to the while loop.

When all of these settings are set and the VI is executed the results will be agilejt in the Measurements array indicator. For other instrument driver types, the examples will be available from the Application Examples subpalette from the corresponding instrument driver. In the following figure we have opened the Agilent Read Multiple Measurements. 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.

This tool searches IDNet to find the specified instrument driver. Make sure that for each successful call to the Initialize VI, you use a matching Close VI to avoid maintaining unnecessary memory resources.
