How to write output from Keithley 220 to Excel using Labview

Hello, I have seen other posts that ask this question and was wondering if anyone has found the solution? I have downloaded the driver and seem to be able to communicate with the instrument. However, I am not very sure how to modify the driver to set the amperage and record the output to Excel.

Hi rachel-d,
It looks like that instrument driver is only one VI, and is not a certified driver.  There seems to be a control for "source (A)" which may be what you're looking for as far as setting the amperage.  Honestly, you may have better luck starting with a simple GPIB communication program and writing your own VI.  You may need to check your device's manual for information on specific commands to set current values, etc.  As for excel, you could use the Write to Measurement File Express VI and write your data to a text-based measurement file (.lvm) that is tab deliminated.  You can then open this file with Excel.  There are also examples you could look at in the NI Example Finder (Help > Find Examples).
Hope this helps!

  • How to write more than 65536 data in excel Via Labview in one column

    I have more than 65536 data and i want to write these data in excel sheet. It is giving Error:-
    "Description:-
    Error -2146827284 occurred at an unidentified location
    This error code is undefined. No one has provided a description for this code, or you might have wired a number that is not an error code to the error code input."
    Less than 65536 data can be written....
    Please give some solution...

    This is not a limitation of LabVIEW writing to a spreadsheet file but a limitation of Microsoft Excel (and also of Notepad) itself.
    One option could be, you can switch to Excel 2007 or higher verison...!!
    Other solution could be, forget about writing to Excel, instead write in some other format and use LabVIEW your other compatible (with large data) application to read it back.

  • How to read data from PC format external disk, using Labview MAC

    Hi folks,
    For years I have not been able to read data files from a PC formatted (created) external disk, using Labview for Mac. More specifically:
     - I have Labview 7.01 running on OS X 10.4.11 on a PowerBook G4
     - I have a 500GB external USB/firewire disk that was formatted on a PC and has data files (custom format) that were created on the PC. I believe that C code actually creates the files, but Labview 7/PC opens the files and appends some info (I don't think the fact that C or Labview touches the files is actually relevant to this issue though).
     - I can connect the 500 GB disk to my mac, and it will mount just fine and OS X can see all of the data files (and anything else on the disk).
     - if I use my Labview app to open and read a data file it fails:
           - open/create/replace.vi (with read-only access) shows a file dialog window that lets me navigate to any file on the external disk.
           - but, the vi returns an error 7
     - if I use OS X to copy the data file to my Mac disk, my Labview app works fine.
    So, does anyone know if:
     - I'm just doing something wrong in my Mac Labview app?
     - Labview 7.x solves this problem?
     - Labview 8/Mac solves this problem?
     - OS X 10.5 solves this problem; with Labview 7 or 8; or does OS X 10.5 worsen the problem?
    Thanks, in advance...

    Hi kehander,
    Thanks for the reply. I tried filling a constant path with the Mac-defined path to a data file on the USB disk (ie "DATA2:file1.dat"). This resulted in the same error message.
    I then considered that maybe I was misinterpreting the LV error message, and that perhaps I was supposed to address the file using PC-notation (ie. "DATA2\file1.dat"), even though the app is running on a Mac. No joy with this, but I get a different error msg:
    "Error 1430 occurred at Open File
    Possible reason(s):
    LabVIEW:  The path is empty or relative. You must use an absolute path."
    Can you share what your reasoning was for your suggestion... I'm not sure I understand why a constant path would produce different results?

    How do I move from one website to another using Safari, while still allowing Pandora to provide music in the background? It seems that when ever I open a new URL, I lose Pandora.

    Try running Pandora in its own tab and leaving that tab open (Safari 7.1.5, OS 10.9.5).  I don't have Pandora to try this, but it works for me otherwise.
    Good luck

  • How to transfer files from mac to ipad without using itunes

    how to transfer files from mac to ipad without using itunes ???
    as i want to use my ipad for official use as well...please suggest..

    well to be 100% technical, no you didn't but that aside, it good to know there are ways for people to transfer music into the default apps without iTunes, if they have a need.
    I tend to use 3rd party apps for documents, like your mentioned iExplorer etc, which are handy.
    I see from a search the two "apps" you mentioned are not iOS apps, which I had assumed, SyncPod and FreeSync are apps for your computer, that would explain their access to the default Music/Video apps.
    I had wondered how Apple had allowed iOS apps in the store that could get around the sandboxing in iOS of apps.

  • How do I print from my I Pad 2 using Airport Express

    How do I print from my I pad 2 using airport express.

    At this time you can't, not if you mean a printer connected via USB to the Airport unless there's been an app or workaround released that I haven't seen, or unless the printer is one of the few wireless printers that support AirPrint or for which the manufacturer has released their own app. At this time only HP has come out with printers that support AirPrint, which allows an iOS device to natively print directly to a wireless printer:
    http://support.apple.com/kb/HT4356
    It's possible other printer manufacturers may provide updates to their printers to make them AirPrint capable. It's also possible that eventually Apple will support printers connected to a computer or Time Capsule. HP also has an app that allows printing to some of their other wireless printers, as if memory serves does Brother.
    If you don't have an HP printer or a another printer with an app available, then for now, you would have to connect the printer to your computer, then search the web for something like "airprint Windows hack" and you'll find instructions on enabling printing. If you have a Mac, try Printopia.

    For saving the report you can goto System -> List -> Save -> Local File -> Location where you want to save in your presentation server.
    You can also give a option in your selection screen to save the file to Presentation server using FM GUI_DOWNLOAD.
