Communicate to a 34970A from 2 VI's at the same time

Im using an Agilent 34970A and i need to have two different VI's running at the same time, one is retrieving measurements from 5 channels of the 34902A (every second) and the other controls the actuator module, at the runtime sometimes it send and error and i cant keep controlling or measuring anything, how can i do it or check if the equipment its in use before trying to use it?
Thanks
Solved!
Go to Solution.

Ok that sounds good, just one more question, when the VISA is locked, and another VI tries to acces to it, it sends a locked error right? will that locked error sent to the equipment too or it just wont let the VI access to the equipment?

  • Is it possible to output multiple clips from a multitrack session, at the same time?

    I'm using Audition CC 2014.2
    on Windows 7 Pro x64
    I am trying to figure out how to output several clips from a multitrack session, at the same time.
    A session like this:
    Is it possible to output 5 files right now?
    I can select each one (or even multiple) and use File > Export > Multitrack Mixdown > Selected Clips to do one at a time only.
    I'm hoping for a way to give each clip (or group of clips) a predefined filename, by perhaps using markers or something like that, which would then allow me to faster "automate" the exporting of each section into a different sound file.
    This ability would be really helpful when using a single multitrack session to generate multiple sounds and a change to globally applied effects is made and all sounds now need to be updated.
    Any ideas?

    They are, yes, but I'm also working with multitrack sessions using clips made from various different sound files.
    Ahh ok, use markers?
    So, this sort of thing isn't possible in multitrack mode then?
    If not, it sounds I'll have to "mix down" my multitrack session into a single file and set up the markers in Waveform Edit view.
    That's an extra step I'd have to do, and after editing the multitrack session, surely some markers . . . oh wait, no . . . every time I output the new mix down file from the multitrack I'd need to redo all the markers. Drat . . .
    Honestly, I am very new to Audition, but I'm about to plow into it, big-time, and I'm hoping for a nice non-destructive and fast workflow that'll enable me to output sets of sounds from the same multitrack session.
    But, it seems like this functionality is currently missing.

  • There is no audio output on my MBA in the system preferences-sound folder. Therefore no sound comes from my computer. At the same time this happened, any streaming video stopped playing after 11 seconds, as well as iTunes will not play any song. Help!?

    Hello everyone.
    i have a 15" MBA circa 2011 running Lion 10.7.5 and my sound has gone, There is a no sound circle on my volume display and in system preferences sound my options for output is empty. At the same time this happened I noticed 2 things: 1) itunes would not actually play any audio track and every video i streamed stopped after a few seconds (usually 11s) but not always.
    I have tried following some tips I have found online like going into MIDI and fixing the problem there, restarting in safe mode. Resetting with PRAM (or something that sounds like that).
    Does anyone have any insight on this? At this point i'm thinking it's time to reload Lion but I don't really know how to go about that without losing all of my files.
    Please Help
    Thanks

  • Reading and Writing from a text file at the same time

    I know who to use the Scanner and PrintWriter to read from and write to a .txt file. But these are limited. How can I read and write at the same time? Such as open a file and change every third character or change every second word to something else and then write it back. I found this [http://java.sun.com/docs/books/tutorial/essential/io/|http://java.sun.com/docs/books/tutorial/essential/io/] but its a little over my head. Is this the only way to do it?

    wrote:
    You are using buffered reads and writes I would assume, right? Also, how do you think most programs handle this sort of thing? I don't believe I'm using buffering.
    My code looks something like this
    //...necessary imports
    //then
    Scanner inFile = new Scanner (new file("filename1.txt"));
    PrintWriter outFile = new PrintWriter ("filename2.txt");
    //then stuff like
    int x = inFile.hasNextInt();
    outFile.println(x);

    Otherwise, you've been given the answer above.What is RandomAccessFile? Is it what I have a link to? Basically what I do is I write a bunch of numbers to a txt file and then change the numbers I don't need anymore to 0. So say I had 0 1 2 3 4 5 6 7 etc. I would like to to open the txt file and change every second one to 0 so then I'd have only odd numbers and 0s.
    I looked at the documentation for RandomAccessFile and it seems like it might be what I need.
    Thankyou both for your help so far. I took a java course in high school and they only taught me one way to get data from text files and that is what I just showed you. So maybe this questions are really stupid. lol

  • The app Spaces keeps me from using two applications at the same time.

    I set up Spaces but now experience a bad side-effect. When I need to have Two files/folders/whatever in use because I want to place something from X into Y, I cannot do it because Spaces only lets One application on the desktop at the time; it shoos all the other applications away, and in doing so, it takes away the thing that I wanted to place into the new application that swooshed onto my desktop when I pressed its corresponding square in the Spaces icon in the top control panel.
    How can I arrange it so that I can keep Two or three applications available for me to do transfers from one to another?
    ~ Lorna in Southern California

    Ferrell, I have done what you suggested. I clicked onto the Spaces icon in the upper control panel and assigned spaces to six apps: Mail, Safari, iPhoto, iMovie, Pages, and iWeb.
    The problem is that if I am one app and I want to put something into that app, then the minute my mouse cursor goes to get that other thing, the original application into which I want the thing put GETS WHOOSHED OFF THE DESKTOP. What I want is for the original app to remain open whilst I go to retrieve a file or folder, and stay open while I put that thing into the original app.
    How does one turn off Spaces? I don't mean to delete all the names from the settings.I mean, just turn it off for a while so I can do something which requires for two apps to be open at the same time????

  • HP DV7 laptop, cant listen and talk from 2 usb headsets at the same time??

    Hi,
    I am trying to use two usb headsets at the same time as my wife and I are doing an online course, but can onle use either one at onc, not both?? Has anyone got any ideas?
    Thanks, Matt

    Hello Mattynsavvy, welcome to the HP Forums.
    It appears that you're trying to use two headphones from your notebook to do an online course.
    The way that you're trying to do this probably won't work. The notebook itself only has one sound card. This card can only output audio to one device at a time. So if you have both USB headsets into ports. Only one will have sound. Just like how the headset cuts off the speakers. You would need a second sound card, or to be using speakers or another computer.
    The only thing I could think of that may accomplish what you're trying is to use the audio/mic jacks on the notebook specifically with a splitter. This may allow the sound to be direct to two headsets. I can not say for certain if this will work or not.
    I was able to find a few YouTube videos with various ways to achieve what you're trying to do, but as they run with 3rd party software attempting those suggestions would be completely up to you.
    I hope this helps.

  • TS3899 hi - why can't i delete emails once from iphone and ipad at the same time?

    When I delete emails from the iphone they still appear in the ipad. Why? How can I delete from both devices at the same time?

    You can and it should be automatic depending on your refresh rate.  If your phone and iPad refresh every hour, or only on request, then the iPad will not show the change until you refresh the email account.
    Next time you delete emails, try it....Refresh the screen on the iPad.
    This only works if iPad has internet connection.

  • Reminders: How to view Todo's from multiple Exchange accounts at the same time

    Does anyone know of an IOS app that:
    Displays a concatenated view of all Tasks from all of my (3) exchange accounts.
    The problem is, that I cannot see what tasks I have for e.g. today without going in and out of all of the Exchange accounts. Just like the calendar is able to view all of the appointments in different colors, I would like the reminders (or a simliar app) to do the same.
    Yes, I'm willing to pay for an app, it's not that :-)
    Thanks for any input!

  • Will ATV 3 output from HDMI and Optical at the same time?

    I'd like to use my apple TV to feed music to my main AV receiver while at the same time sending that same audio signal out the optical out connection to my other AV receiver that provides music to all of the rooms in my home. Right now it feeds the music to my main AVR via HDMI just fine but nothing to my other AVR.
    Is this possible?

    We've used an airport express since 'the beginning' - for years to get our Wifi from our cable modem in our garage while simultaneoulsy using it to output audio to a VERY old tuner in the garage. I have some nice outdoor Bose speakers connected to this setup which allows any mobile device wifi equiped to output any audio through my setup.... i.e. we usally use iTunes off our laptop while we are chilling outside. Perfect marriage of new school and old school technology.

  • How can I get the selected rows from two ALV grids at the same time?

    I have a program that uses two ALV grids in one dialog screen. I'm using the OO ALV model (SALV* classes).
    The user can select any number of rows from each grid. Then, when a toolbar pushbutton is pressed, I'd have to retrieve the selected rows from both grids and start some processing with these rows.
    It is no problem to assign event handlers to both grids, and use the CL_SALV_TABLE->GET_SELECTIONS and CL_SALV_SELECTIONS->GET_SELECTED_ROWS methods to find out which rows were marked by the user. Trouble is, this only works when I raise an event in each grid separately, for instance via an own function that I added to the grid's toolbar. So, I can only see the selected rows of the same grid where such an event was raised.
    If I try to do this in the PBO of the dialog screen (that contains the two grids), the result of CL_SALV_SELECTIONS->GET_SELECTED_ROWS will be empty, as the program does not recognize the marked entries in the grids. Also, an event for grid1 does not see the selected rows from grid2 either.
    As it is right now, I can have an own button in both grid's toolbar, select the rows, click on the extra button in each grid (this will tell me what entries were selected per grid). Then, I'd have to click on a third button (the one in the dialog screen's toolbar), and process the selected rows from both grids.
    How can I select the rows, then click on just one button, and process the marked entries from both grids?
    Is it somehow possible to raise an event belonging to each grid programmatically, so that then the corresponding CL_SALV_SELECTIONS->GET_SELECTED_ROWS will work?
    Thanks.

    Hello Tamas ,

    is it possible to  have a check box in each grid  & get the selected lines in PAI of the screen ?

  • Mail sending from 2 gmail accounts at the same time

    I currently have 2 gmail accounts, one is a Personal account that I use 90% of the time and the other is a Family account. I have them set up to sync through Apple Mail. Since upgrading to Mavericks, whenever I send an email from my Personal account, it appears that it is sending from both accounts even though I only selected to send from my Personal account. The most frustrating part is that the recepients show that it is coming from my Family account. Therefore, when they reply to my original email, the reply comes to my Family account. Does anyone else experience this or have a solution?
    Thanks

    Think I solved my own problem. It seems I just needed to delete both of my gmail accounts from Mail, restart computer, and re-add the accounts. Seems to be working now.

  • Open one than more file from Lightroom to photoshop at the same time

    I use PSE9 and send several derivate files (TIFFs) from LR to PSE9 all the time to do panos.
    I've recorded a little screen capture showing 4 images being sent to PSE9 from LR3.6. You can see the 4 tiffs being added to the catalog before calling PSE9 and then the 4 TIFFs arrive in PSE9.
    What Operating System do you use? Can you show a screenshot of the external editor settings for PSE?

  • How can I display a avi-file while acquiring data from a DAQ-CARD at the same time

    While my system is acquiring analog data and controlling a motor, I want to display a avi-film (preferably in full-screen, so that the LabView GUI disapears during this process). Are there any VI's to open external players? May I face some problems to lose samples, due to the calling of external players?
