The logging you have inside the loop makes no sense. Sample code created with instrument driver functions. Like Dennis said look at the examples, my “Scan-now. Use the instrument driver VIs to define your custom application. The driver also includes a full set of functional building blocks that can be used to create a completely custom A application in LabVIEW. The programme works fine and I receive a text data after logging. Two instrument driver palettes are shown below, in Figure 2.

Setting up the hardware to achieve these high rates, resolutions, and channel counts has never been easier or quicker. Continuous data acquisition with Agilent A. I am pretty sure that I have to use a While Loop but I don’t know where to put it.
I want new temperatures and voltages been logged every ms. Can you help me fix my problem? Thank you for the response. They only get updated once and you keep writing stale data. But it seems as if LabVIEW records labivew channels step by step and there are always about 5s between two different temperatures or voltages for each channel.
But both together is not working the way I want to.
LabVIEW can also be used to interface with a data management system, whether that consists of a simple spreadsheet file or a relational database. Bob Schor 28 August If you are looking for an easy way to increase the speed, sensor support, and channel count of agulent test and measurement system then you may want consider adding NI CompactDAQ hardware to your setup.
It displays the acquired data on a front panel indicator not pictured. Turn on Context Help and read the function descriptions. Could you give me some advice? Back to Top 2. Figure 1 shows the graphical user interface of one of the A example programs, used to control the A matrix switch module. I just deleted the two While Loops and put one around everything.
The most straightforward way to take advantage of the LabVIEW instrument driver is to run the example programs, which require only basic aagilent configuration. Here is an example of steps configuring DC volts, Scaling DC shunts, K type thermocouples, and building a scan list.
Even my data logging part works well.
Thank you for the helpful response. In Figure 3, we show the block diagram of a sample application created with these VIs. Yes, in order to continuously read, you must use a while loop. The problem is that I don’t know how to choose and change a channel when I don’t split them. You must follow these steps.

I changed my VI and now I can configurate the measurements. It should be around the scan and read function. Thanks again for your help. For resources that outline the fundamentals of this industry-standard development environment, please refer to the links at the end of this section.
