• I'm new to Labview. How can I save oscilloscope data in a text file?

  Hello

  I have an oscilloscope (TDS2000) connected to my computer via USB. I want to record the oscilloscope data in a text file or a spreadsheet using labview. I'm new to labview. I only know about front panel and block right now. Please include a bit of inmates explain about data acquisition. Thank you

  I already said that your question has nothing to do with data acquisition devices of NOR. This means that DAQmx has nothing to do with it. You do NOT data, as defined in the world NOR / LabVIEW. On the main page of The Instrument Driver Network , you will see a section called "using the Drivers." The links that explain how to use the driver that you downloaded. The functions that you will be sliding to diagram must be in the Instrument of e/s palette, assuming that you have installed the driver properly.

  Hi Experts,
  
  I want to load the data from a text file (sample1.txt) to a table using pl/sql
  
  I used the pl/sql code below
  
  ***********************************
  declare

• Average data from multiple text files

  I am new to labVIEW so any help is appreciated:

  I have a 100 txt files with two columns (separate tab) for a value of X and Y.

  I need the average of the values of Y to generate a single file and generate X against Y graph.

  So, how to read the data of these text files? (without having to select each one individually) and the average data and create a chart XY him?

  Thanks in advance

  There is a function to list folder in the palette of the file i/o that will return an array of file names.  Feed this table in a loop to open and read each file in turn.  Put in a new file, build a table with her, process the data or do whatever you want.

• item switch to function index into a text file

  I'm having some difficulties here...

  What I want to do is replace/switch element to an index in an existing text file. When I read the data from the text file I use 'read worksheet file.vi' and read items as strings, so my idea is to use the "write to worksheet file.vi' when I want to update the text file.

  For example, a text file with elements; 1-1-1

  2-2-2

  3 3 3

  An example of what I want to do is to change the place of the first 1 to index (0,0) and the last 3 in index (2.2), which should give me the result in the text file; 3-1-1

  2-2-2

  3 3 1

  Anyone who got advice or ideas? Thank you...

  You should really look at the various functions of table available. And rather than use the function Rotate 1-d array , you can try using the first remove table , then insert into the Array function.

• Writing data in the text file or excel spreadsheet

  Hello

  I have a silly question to ask questions about the writing of data in a text file or a spreadsheet. I have an example that simulates a sine-swept DAQmx. The output it provides is the (amplitude and phase) frequency response function that is plotted on a graph (see VI) attached. I like to use these data for further analysis by transmitting the data to a text file or a spreadsheet. I've tried a few things, but the thread is broken. I guess I use the sink badly - so I was wondering, can you please advise me on what sink should I use?

  Your help would be very appreciated,

  Thank you very much

  REDA

  The wire is broken, because you cannot connect this type of data to one of these two functions. The data source type is a table 1 d of the clusters, where each cluster contains two tables. The text file write accepts strings, not clusters. Writing on a file action accepts dynamic data, and while you can convert dynamic data tables, there is no built-in mechanism to convert a table 1 d of the clusters of two matrices.

  What you need to do is to convert the data in a format which can be accepted by these functions. Since you want to have a "spreadsheet" file then you should use writing to the spreadsheet file that creates a delimited text file. Since the frequency data would be the same for the plot of the magnitude and phase diagrams, you can have 3 columns: frequency, amplitude, and phase. You can take off the items using Unbundle by name, and then create a table 2D of each element of the cluster. The real question is to know if you want to save the data at each iteration and if you simply add on the file. The attached figure shows write an initial header and then adding just streaming the data.

• How to view the data in the text file to the format column

  Hello

  I am acquiring data from an oscilloscope.

  Wen I save the data in a text file to aid wite spreadsheet string, all the displayed voltage values r first, then values of time... in addition to its delimited by tabs

  How can I view it like the r of time values in a single column and the voltyage of the r-values in the other column

  thanx

  Hello

  I don't know what is exactly the format that you found. I think you should try to use the function Array transpose (from the palette of function table) before you pass the array to write to string of spread sheet function or directly loyal to Terminal son transposes on writing worksheet function and see if you get the desired results.

  PS. : Share your code would be appreciated.

  Kind regards

• How to save data in the text file of Spartan 3

  Hi all

  I would like to kindly save the data table text file or a spreadsheet on vi using fpga spartan 3e as an fpga target. Once I added all the functions related to the operation of file, it gave an error that these functions are not supported by the target device.

  could you please help me with this

  Thank you

  Rania

  Hi David,

  Thank you for posting. You use LabVIEW? If so, what version of LabVIEW FPGA do you use? You use a host VI, or any deployment of code at your target to run? The file IO VI probably won't compile to target because they are not intended to be used on your host computer. Resources and the paths of files do not exist on the target FPGA, but rather on the side of the host. I have included a link below that describes how to transfer data between the FPGA and host. I hope this helps!

• How to add data to a text file?

  Hello

  I want to add data to a previously created text file. When I used writing text file.vi. It replaces previous data.

  Try to use the function "set position in the file" (file e/s palette, advanced functions) before writing the data.

  either open the file, position set to finish, write the data, close the file.

• How to extract specific data from a text file

  Hello world

  For my project, it is necessary that a parameter file is read at the beginning, so that variables be initialized with specific values that change with the user.

  For now, the mode of action is as follows: the values in a sequence specified in a text file are read and saved in a table and the elements of the array are extracted according to their index.

  The problem with this implementation is, that if for any reason any changes file format, for example we want to use a settings file from a previous version of the program, which has the values for the variables of same but in a different order, the only way to have good values for the parameters is to change everything accordingly which is really time wasting.

  Could someone suggest another implementation that make reading the different values independently of their order in the file, for example by analysing the file for specific strings and by reading the value after the string?

  Thank you very much.

  P.S. I've attached a screenshot of the routine, which I use now.

  Hi panagiov,

  Find attached files.

  Method 1: in this you can search for each variable separately. You can use "Live Config file" to get all the keys (variable) at a time, and then you can use for loop to get their values. Or you can access values as indicated in the present code.

  Method 2: Here you will have all the data at once. You will get variables and data (table 2D), you should look for the variables as needed.

  I hope you understand these methods.

  Good luck

• Import data from the text file to open the Document

  This should seem simple, but I can't find a way to import a text file delimited to tab automatically on opening the document.  I can open my form fill pdf document, select Forms > more form Options > data management > Import Data > change the bottom right "Text (*.txt) files" file type, select the file, then import with no problems.  I can't find a way to do this automatically when the document opens.  I know a *.fdf file will do, but my data are in a tab delimited text file.  If this is not possible, is there a program or a script that will convert *.txt to import *.fdf?  Thanks for your time.  Steve

  Have you looked at using custom JavaScript?

  importTextData

  You will need to work on how the data file select the line form.

• is it possible to convert a check into readable text file?

  is it possible to convert a check into a readable text file?
  
  Also, I can say that the content of the control files you will find in the alert.log?
  
  Thank you

  See previous answers.
  There is also an undocumented option to see a dump of debugging of certain other information in a control file if you have access to your trace files:

  alter session set events 'immediate trace name controlf level 16';
  

  From memory I think level 16 is more complete emptying, but there may be another level this report more.
  Do not experiment with this on a production system.

• Why converts the images into a text file?

  I found that when I opened some art work that I have done in Illustrator CS4 work seems itself have converted into text files.

  Could someone tell me why this is happening. I seem to have lost the work which took many hours. I'm puzzled.

  Grateful for any advice.

  Kind regards.

  What gives you the impression that they are text files? The original format of the files was Postscript, a text format, but who died with AI9. Here is the PDF format.
