The 4192a driver is a poorly written driver, what there is of it, which isn't much. It does not save data anywhere. The example simply displays the data on a graph. If you want to save it to file you have to do this yourself by adding (for example) a Write to Spreadsheet File function and passing it the array of data.

Can you attach such program. because I don't know labview so. I have studying to learn for a few weeks. How can I find that program you mentioned? thanks...

The Write to Spreadsheet function is on the File I/O palette. If you just want the array results saved, wire the DBL array from the sweep function to the 1D Data input of Write to Spreadsheet. To include the start and stop frequencies, you do inlcude them in a couple of different ways. You can use separate Write to Text File functions or create a 2D array from the start/stop/data and wire that to the 2D Data input of the the Write to Spreadsheet.

Why don't you look at the shipping examples of file writes and give it a try. Post back and attach you code if you get stuck.

Thank you very much. I am going to try to do your suggest. It is too diffucult to realize this operation because I don't know so much.  Thanks again.

Hi,

I couldn't carry out the steps you mentioned. I have trying to solve since monday but I couldn't be succesful. I attached the hp4192a sweep.vi function I tried to modify. hovewer its run array was broken. Please, could you help me about this trouble. thans a lot...

If you click on the Run button it will tell you what the problem is. The problem is that your Concatenate Strings function has three inputs, but you've only wired 2 of them. I don't understand why you're doing all that instead of just using the Write to Spreadsheet File like Dennis said. That's just one VI.

To learn more about LabVIEW it is recommended that you go through the tutorial(s) and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free.

Something like this is what you should be doing.
