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. In no event shall the author, xDevs. Thousands of instrument drivers, including the driver for the Agilent A, are available for free download from ni. Message 7 of 9. In Figure 3, we show the block diagram of a sample application created with these VIs. Each routine that composes the driver corresponds to a programmatic operation such as configuring, reading from, writing to, or triggering the instrument. LabVIEW is an industry-standard graphical programming environment that can be used to quickly and easily acquire, analyze, and present data from the A.

DC'” DCV mode kei. I don’t understand the DMM or its language well enough to know what to do. It may be useful to verify the actual data coming in and make sure that it’s not just an issue with the way the information is being displayed.
It’s a VISA property. The 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.
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. Two instrument driver palettes are shown below, in Figure 2.
Agilent Technologies / Keysight Technologies 3458A
Message 2 of 9. Use a property node on the VISA reference. This can be useful to set delays in code to allow meter perform auto-calibration to minimize errors. Have you taken a look at the set of data that’s being read in any way other than the graph? LabVIEW itself is a graphical development environment for creating flexible and scalable test, measurement, and control applications rapidly and at minimal cost. Keysight A Multimeter datasheet.
Using the Agilent A with LabVIEW – National Instruments
3458aa 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. Message 5 of 5. It displays the acquired data on a front panel indicator not pictured.
Sample code created with instrument driver functions. Any custom LabVIEW application you create will be labvieww 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. Each routine that composes the driver corresponds to a programmatic operation such as configuring, reading from, writing to, or triggering the instrument.
Is there a VISA command to turn it off and on?

Using the Agilent 34980A with LabVIEW
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. So if you have a data point of 10, then the read will stop with that character.
Message 2 of 5. The graph displays the data exactly as it would be displayed in an Excel sheet.
Most Active Software Boards: Is it just not giving you enough accuracy, or is it causing other issues with your code? All information posted here is hosted just for education purposes and provided AS IS.
I want to capture and store the voltage values into an array for post processing. Message 8 of 9.
