There are several advantages to using the dll form of the driver. Then the Configure Measurement VI is called to set the instrument up for the desired measurement. Thousands of instrument drivers, including the driver for the Agilent A, are available for free download from ni. The driver also includes a full set of functional building blocks that can be used to create a completely custom A application in LabVIEW. Then, with the example running, the user can toggle any LED in the array to open or close a matrix cross point on the A module.

LabVIEW can also be used to interface with a data management system, whether that consists of a simple spreadsheet file or a relational database.

Second, there is no knowledge base file, which is primarily a description of a VXI board. NI CompactDAQ combines USB device detection, built-in signal conditioning, direct sensor and signal connectivity, hot-swappable modules, and automatic module 349a to make a simple, complete, cost-effective data acquisition system all in one small platform.

Back to Top 2. LabVIEW is an industry-standard graphical programming environment that can be used to quickly and easily acquire, analyze, and present data from the A.

The Configuration VIs- a collection of software routines that configure the instrument to perform the operation you want. With these, you can quickly and easily take your application far beyond merely programming the instrument to create a completely user-defined solution. In Figure 3, we show the block diagram of a sample application created with these VIs.


In the following figure we have opened the Agilent Read Multiple Measurements. To run this example, the user first sets the GPIB or serial communication parameters.

Instrument drivers simplify instrument control and reduce test program development time by eliminating the need to learn the programming protocol for each instrument. When you wish to extend the capabilities of the examples, or wish to start a new custom application, the set of LabVIEW functions installed with the instrument driver provide all the building blocks you will need.

The Data VIs- transfer data to or from the instrument. oabview

The driver uses Pascal calling conventions. 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.

The only exceptions are that it does not have a soft front panel or a knowledge base file. A significant advantage of customizing your LabVIEW application is that it enables you aiglent combine the unique functions of the instrument driver with the standard functions built-in to LabVIEW. The Action VIs – initiate or terminate test and measurement operations, such as arming the trigger system or generating a stimulus.

Make sure that for each successful call to the Initialize VI, you use a matching Close VI to avoid maintaining unnecessary memory labivew.

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. The help file presents application programming examples, a cross-reference between instrument commands and driver functions, and detailed documentation of each function, with examples. It includes a Visual Basic include file. Any custom LabVIEW application you create will be composed of a front panel, which is the graphical user interface, and a block diagram, which is the flow chart-style code created with these functional blocks VIs.

It is built on top of, and uses the services provided by VISA. For Windows NT, change references from win95 to winnt. Source is included so that the driver can be modified if desired. Action VIs are different from Configuration VIs because they do not change the instrument settings but order the instrument to carry out an action based on its current configuration. After you call these VIs, the instrument is ready to take measurements or to stimulate a system.

Examples include VIs for reading a measured value or waveform and VIs for downloading waveforms or digital patterns to a source instrument.

You must also provide an include path for ag Most instrument ,abview have menu palettes that include the following components. There are several advantages to using the dll form of the driver. Once an instrument driver has been downloaded, the instrument driver VIs will be located on the Instrument Drivers palette.
