Thank you for the response. 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. Use the instrument driver VIs to define your custom application. 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. Look at the attached VI or the examples that come with the instrument.

Thank you for the response. I attached my VI and a text data to show labvifw how it looks like. Since peak detection is one of the analysis functions available in LabVIEW, we can easily add that functionality to our application. Message 10 of Thousands of instrument drivers, including the driver for the Agilent A, are available for free download from ni. It should be around the scan and read function. I would like to here your recommendation about this subject.

Use the instrument driver VIs to define your custom application. I tried everything put my txt data looks always like in the attached jpg. Each routine that composes the driver corresponds to a programmatic operation such as configuring, reading from, writing to, or triggering the instrument. Message 1 of Yes, in order to continuously read, you must use a while loop.


Using the Agilent A with LabVIEW – National Instruments

labviea This application initializes communication with the A, takes 10 voltage readings from each channel in the scan list, and finally ends labviea and checks for errors.

I changed my VI and the reading and scanning works fine. Instead of telling me how to use the agilent tool which I have oneit explains why I should buy something lwbview.

Thank you very much and if anything isn’t clear yet, just ask. In Figure 3, we show the block diagram of a sample application created with these VIs. Even my data logging part works well. The most straightforward way to take advantage of the LabVIEW instrument driver is to run the example programs, which require only basic user configuration. Could you give me some advice?

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. I just deleted the two While Loops and put one around everything.

Okay I got it. Can you help me fix my problem? Instead of the monitor function and reading one channel at a time, use the function to read the entire scan.

Using the Agilent 34970A with LabVIEW

With these, you can quickly and easily take your application far beyond merely programming the instrument to create a completely user-defined solution.


To run this example, the user first sets the GPIB or serial communication parameters. Like Dennis said look at the examples, my “Scan-now. Here is an example of steps configuring DC volts, Scaling DC shunts, K type thermocouples, and building a scan list.

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.

Figure 1 shows the graphical user interface of one of the A example programs, used to control the A matrix switch module.

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. The configuration should be outside the loop. Do I really have to use a While Loop or is there a function I don’t know yet? Thank you for the helpful response.

National Instruments provides a free LabVIEW instrument driver for the Lavbiew, which gives you programmatic control over the unit from your PC, while having to do little or no programming yourself.
