Unlike other programming environments, all programming in LabVIEW is done graphically through intuitive flowchart-style coding and functional blocks. Introduction to the A Instrument Driver An instrument driver is a set of software routines that control a programmable instrument.
National Instruments provides a free LabVIEW instrument driver for the A, which gives you programmatic control over the unit from your PC, while having to do little or no programming yourself. Sample code created with instrument driver functions. 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. Since peak detection is one of the analysis functions available in LabVIEW, we can easily add that functionality to our application.
LabVIEW can also be used to interface with a data management system, whether that consists of a 11713z spreadsheet file or a relational database. As outlined above, using the A with a LabVIEW agileent driver creates a useful PC-based virtual instrumentation system for acquiring, analyzing, and presenting test data.
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.

Each palette represents a distinct category of instrument driver functions for programming the A. This document introduces the instrument driver and also discusses an alternative hardware option to the A that can add speed and sensor compatibility to your PC-based measurement system, depending on your application. NI CompactDAQ combines USB device detection, built-in signal conditioning, direct sensor and signal connectivity, hot-swappable modules, and automatic module configuration to make a simple, complete, cost-effective data acquisition system all in one small platform.
Rate this document Select a Rating 1 – Poor 2 3 4 5 – Excellent. The most straightforward way to take advantage of the LabVIEW instrument driver is to run the example programs, which require only basic user configuration.
To run this example, the user first sets the GPIB or serial communication parameters.
For resources that outline the fundamentals of this industry-standard development environment, please refer to the links at the end of this section. I would like to here your recommendation about this subject. Hundreds of functional blocks for analysis, signal processing, and mathematics are built-in to the environment, making LabVIEW a smart choice for manipulating raw data collected with the A.

However when the voltages around 4. Thousands of instrument drivers, including the driver for the Agilent A, are available for free download from ni.
The 11173a CompactDAQ platform is an excellent hardware option to consider when adding to or creating a user-defined, PC-based data logging or bench top automated test system. It displays the acquired data on a front panel indicator not pictured. An instrument driver is a set of software routines that control a programmable instrument. If you are looking for an easy way to increase the speed, sensor support, and channel count of your test and measurement system then you may want consider adding NI CompactDAQ hardware to your setup.
LabVIEW itself is a graphical development environment for creating flexible and scalable test, measurement, and control applications rapidly and at minimal cost.
Please try again, only this time explain how to use Labview with the Agilent instrument. Six such ready-to-run examples are provided by National Instruments in the driver. A significant advantage of customizing your LabVIEW application is that it enables you to combine the unique functions of the instrument driver with the standard functions built-in to LabVIEW.
LabVIEW is an industry-standard graphical programming environment that can be used to quickly and easily acquire, analyze, and present data from the A. Instead of telling me how to use the agilent tool which I have oneit explains laview I should buy something else.
Using the Agilent A with LabVIEW – National Instruments
Each routine that composes the driver corresponds to a programmatic operation such as configuring, reading from, writing to, or triggering the instrument. Two instrument driver palettes are shown below, in Figure 2. 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. This application initializes communication with the A, takes 10 voltage readings from each channel in the scan list, and finally ends communication and checks for errors.
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 A.
