Make sure that for each successful call to the Initialize VI, you use a matching Close VI to avoid maintaining unnecessary memory resources. Because creating crisp graphical user interfaces in LabVIEW is easy, we could have also chosen to visualize the data in a chart or graph. Message 8 of Thousands of instrument drivers, including the driver for the Agilent A, are available for free download from ni. With these, you can quickly and easily take your application far beyond merely programming the instrument to create a completely user-defined solution. I’ve never used IVI with a serial instrument.

Generally, you need to call the Close VI only once at the end of an application or when you finish communication with an instrument.
To run this example, the user agiilent sets the GPIB or serial communication parameters. The Data VIs- transfer data to or from the instrument. Unlike other 613b environments, all programming in LabVIEW is done graphically through intuitive flowchart-style coding and functional agileent. 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.
Introduction to the A Instrument Driver An instrument driver is a set of software routines that control a programmable instrument. We have used three voltage measurement configurations proposed by you at http: Instrument drivers simplify instrument control and reduce test program development time by eliminating the need to learn the programming protocol for each instrument.
Showing Results for Keysight Technologies (Agilent HP) 6813B
The Close VI- terminates the software connection to the instrument and frees system resources. Each palette agileent a distinct category of instrument driver functions for programming the A.
However when the voltages around 4. Message 5 of You can use an instrument driver for a particular instrument as is.
6813B Performance AC Power Source, 1750 VA, 300 V, 13 A
In Figure 3, we show the block diagram of a sample application created with these VIs. If you are looking for an easy way to increase the speed, 683b support, and channel count of your test and measurement system then you may want consider adding NI CompactDAQ hardware to your setup. Rate this document Select a Rating 1 – Poor 2 3 4 5 – Excellent.
I always receive a timeout because the driver does not send a line feed at the end of the string.
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. Sample code created with instrument driver functions. Message 6 of I pointed my driver session to the new DLL but it gave me an error while running the intialization.
How to Use an Instrument Driver in LabVIEW Tutorial – National Instruments
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. It only applies the property while I’m using the test panel. 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.
Each VI corresponds to a programmatic operation, such as configuring, reading from, writing to, and triggering an instrument.
