Welcome to the NI Community From students to rocket scientists, the NI Community allows the NI Ecosystem to work together towards engineering success. A. There is a free Lab. VIEW instrument driver for the 3. A, which gives you programmatic control over the unit from your PC using Lab. VIEW. This instrument driver will allow you to use your 3. A, while having to do little or no low level VISA programming yourself. This document introduces the instrument driver and discusses additional hardware resources for DMMswitch applications. Laboratory Virtual Instrument Engineering Workbench LabVIEW3 is a systemdesign platform and development environment for a visual programming language from. Introduction to the 3. A Instrument Driver. An instrument driver is a set of software routines that control a programmable instrument. Thousands of instrument drivers, including the driver for the Agilent 3. A, are available for free download from ni. Instrument drivers utilize a set of commands provided by the instrument vendor to communicate with the instrument, often through GPIB, Serial, Ethernet, or USB. Each routine that composes the driver corresponds to a programmatic operation such as configuring, reading from, writing to, or triggering the instrument. Muvee Autoproducer 4. Instrument drivers simplify control and reduce test program development time by eliminating the need to learn the unique programming and communication protocol for the instrument. Lab. VIEW itself is a graphical development environment for creating flexible and scalable test, measurement, and control applications rapidly and at minimal cost. Unlike other programming environments, all programming in Lab. VIEW is done graphically through intuitive flowchart style coding and functional blocks. Hundreds of functional blocks for analysis, signal processing, and mathematics are built in to the environment, making Lab. VIEW a smart choice for manipulating raw data collected with the 3. A. With Lab. VIEW, application development is fast and easy for all users, regardless of experience. While the Lab. VIEW instrument driver for the 3. A itself does not include ready to run example programs, there are three ready to run example programs available from www. Of course, using the ready to run examples requires no Lab. VIEW coding. The driver includes a full set of functional building blocks that can be used to create a completely custom 3. A application in Lab. VIEW. See Also Instrument Driver Network. Lab. VIEW Guided Tour. Back to Top. 2. Using the Instrument Driver Examples in Lab. VIEW. The most straightforward way to take advantage of the Lab. VIEW instrument driver is to run the example programs, which give the user a basic introduction to the programming flow for the driver. Using these example programs as a starting point, it is possible to begin communicating with the Agilent 3. A very quickly, eliminating the difficulties associated with starting a project from scratch. Three ready to run examples are available from Agilent for the 3. A platform. These are Muxexample Demonstrates configuring the 3. A to take measurements from a thermistor, several resistance channels 2 wire and 4 wire, and basic voltage channels multiplexed to the internal digital multimeter DMM. DACexample Demonstrates creating a voltage trace, outputting it through the 3. A analog output module, and reading the output back to the DMM. Dig. IOexample Demonstrates reading and writing digital information and configuring the totalizer for event counting. Though all of these examples are intended to serve as a starting point for the creation of a custom application, they may be used without modification to immediately control the Agilent 3. A. Back to Top. 3. Creating Custom 3. A Lab. VIEW Applications. When you wish to extend the capabilities of the examples or wish to start a new custom application, the set of Lab. VIEW functions installed with the instrument driver provide all the building blocks you will need. In Lab. VIEW, each of these programmatic building blocks is called a virtual instrument, commonly referred to as a VI. Any custom Lab. VIEW 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. Creating a custom 3. A application in Lab. VIEW does require a basic familiarity with Lab. VIEWs graphical programming. For resources that outline the fundamentals of this industry standard development environment, please refer to the links at the end of this section. When the Lab. VIEW instrument driver for the 3. A is installed, palettes containing high, mid and low level instrument driver VIs are made available to you in Lab. VIEW. Each palette represents a distinct category of instrument driver functions for programming the 3. A. Two instrument driver palettes are shown below, in Figure 2. Use the instrument driver VIs to define your custom application. In Figure 3, we show the block diagram of a sample application created with these VIs. This application initializes communication with the 3. A, configures a switch scanning operation, takes 1. It displays the acquired data on a front panel indicator not pictured. A significant advantage of customizing your Lab. VIEW application is that it enables you to combine the unique functions of the instrument driver with the standard functions built in to Lab. VIEW. With these, you can quickly and easily take your application far beyond merely programming the instrument to create a completely user defined solution. Lets suppose, for instance, that after acquiring data in the example above, we wish to detect the peak values in the data set and log those to file. Since peak detection is one of the analysis functions available in Lab. VIEW, we can easily add that functionality to our application. Lab. VIEW can also be used to interface with a data management system, whether that consists of a simple spreadsheet file or a relational database. The block diagram in Figure 4 extends the functionality of our previously created code to discover the peaks of the dataset and then log those values to a tab delimited text file compatible with Excel. Figure 4. Sample Code Showing Peak Detection and Saving to File. Because creating crisp graphical user interfaces in Lab. VIEW is easy, we could have also chosen to visualize the data in a chart or graph. We could have even posted the applications user interface to a web page for remote monitoring and control using the built in Lab. VIEW web server. For information on the features available in Lab. VIEW, or to immediately test drive Lab. VIEW free online, please refer to the links below. See Also Lab. VIEW Test Drive. Lab. VIEW Home. Back to Top. Additional Hardware Resources for DMMSwitch Applications. Instrument drivers offer a compelling method of programming through GPIB, USB, Ethernet, or serial communication ports on stand alone instruments. National Instruments also provides a wide range of digital multimeter and switch products available in the PXI, SCXI and USB form factors that use similar instrument driver technologies with dozens of native example programs written for Lab.
