where is my HP 4192A data

[960310]

Thank you very much for every thing. I am going to try that you wrote.  Thanks again...

I applied your suggestions. It works perfectly. Thank you very much.

So, I tried to show the frequency display but I couldn't. I don't know where my mistake is. Can I carry out that?. Thanks a lot.

I have no idea what you mean. If the modification to add the Write to Spreadsheet is working perfectly, that means that there is display a, b, an c data correct? What is missing or is there nothing in one of the displays?

[960310]

I want to see display C (frequency display). I wired the display C to Build Array. and then to the Write To Spreadshhet File.vi. I changed output to D1 from D0 and added F1 to apply that in second Stacked Sequence. First row in spreadsheet I created is display C. But there are only 0 (zero) values in this row. the other rows generates normal values. thank you

The wiring is correct and if there is nothing in the file, then the array is empty to start with and it would be empty in the front panel of your modified VI. I can't help with the debug of the code since I do not have the instrument.

Thank you Dennis.

I am going to try again. I think I should to learn more.  I made ambitious that. Thanks again

Hello,

I am also getting to know the 4192A the hard way. I would like to sample various frequencies and measure the R and X. I was looking at the vi devoloped by the user "960310". I was looking at the vi and it seems like all of the data from 4192A comes in on a single string. Is this true? Then the individual elements are selected by defining the start place in the string and the length of the segment. I am interested in different data. I would like to catch R and X. So can I redefine the parameters for the display to A2 (B will be fixed) and then pick out the same parts of the string?

Thanks for any advice,

Ian

Hello iprycejr,

I'm don't think 960310 is still monitoring this thread, as his account has been inactive since May 5th of 2010. I don't know anything about the code that he wrote, or how it functions, but is there a reason you arent using the plug-and-play driver for this device? It can be found here: http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=956.

Thank you for the reply T-REX$.

The reason I was not using the driver is because I have a thick skull and I did not think to look for something like that.

I will check it out,

I hve seen that interface... It is very well made and if you only want to do single spot measurments is is geat. The vi I mentioned earlier is beter suited to the task I am working on. It reads a series of frequencies from a text file, takes measurments at those frequencies and writes the results to a seperate text file. I can manipulate it in order to get the measurments I want... I was just trying to get the description for the GPIB string that the 4192A puts out.
