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. With these, you can quickly and easily take your application far beyond merely programming the instrument to create a completely user-defined solution. LabVIEW itself is a graphical development environment for creating flexible and scalable test, measurement, and control applications rapidly and at minimal cost. 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. Using these example programs as a starting point, it is possible to begin communicating with the Agilent A very quickly, eliminating the difficulties associated with starting a project from scratch.

Using the Agilent A with LabVIEW – National Instruments
Instruments under control are: The Agilent A is a good instrumentation solution for manual bench top testing or multiple automated test equipment use cases. FTP ip Use ftplib ftp. This tool also can reset destructive overload counter in readed dump, if you doing service on the unit and need fresh calibration. This can be useful to set delays in code to allow meter perform auto-calibration to minimize errors. To save VFD life, you may want to output just empty spaces.
The block diagram in Figure 4 extends the functionality of our previously created code to discover the peaks of the labviwe and then log those values to a tab-delimited text file compatible with Excel.
Front panel is not meant for easiest operation, and require decent amount of time invested into programming button scripts and subroutines to perform common tasks quickly.
LabVIEW itself is a graphical development environment for creating flexible and scalable test, measurement, and control applications rapidly and at minimal cost. We could have even posted the application’s user interface to lahview web page for remote monitoring and control using the built-in LabVIEW web server.

Quick Reference Guide, Edition 2, Dec Introduction to the A Instrument Driver An instrument driver is a set of software routines that control a programmable instrument.
Three ready-to-run examples are available from Agilent for the A platform.

LabVIEW can also be used to interface with a data management system, whether that consists of a simple spreadsheet file or a relational database. While the LabVIEW instrument driver for the A itself does not include ready-to-run example programs, there are three ready-to-run example programs available from www.
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.
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. Labgiew most straightforward way to take advantage of the LabVIEW instrument driver is to run the example programs, which give the user a basic introduction to the programming flow for the driver.
This application initializes communication with the A, configures a switch scanning operation, takes 10 voltage readings from each channel in the scan list, and ends communication checking for errors. The driver includes a full set of functional building blocks that can be used to create a completely custom A application in LabVIEW.
Thousands of instrument drivers, including the driver for the Agilent A, are available for free download from ni. It displays the acquired data on a front panel indicator not pictured.
Using these example programs as a starting point, it is possible to begin communicating with the Agilent A very quickly, eliminating the difficulties associated with starting a project from scratch. Unlike other programming environments, all programming in LabVIEW is done graphically through intuitive flowchart-style coding and functional blocks.
In Figure 3, we show the block diagram of a sample application created with these VIs. This file will be written to remote FTP location for automatic graph plotting. 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.

It can be incorporated into a more powerful and user-defined virtual instrumentation solution by taking advantage of LabVIEW’s unique instrument control, analysis, and user interface features.
