How do I let a vi know that sweeps are complete?

I am very new to Labview and I have just set up a vi that allows me to average the data in channel 1 as trace A (LeCro 9354AM). I was wondering if there was a way to let the vi 'know' that the sweeps are finished so that I can move to the next operation automatically.

Have you looked in the LeCroy programmer's manual for a command that queries the instrument if sweep is complete?
If such a command does not exist, then you could query the instrument for the sweep time after configuring the sweep parameters.  You would start a sweep and wait the duration of the sweep and then cpntinue with the code.  The wait time would adapt to the sweep time.  There must be a sweep time query command for that particular model.

  • HT201250 How do you let time machine know that a restored drive does not need a brand new backup set and just append to the old one?

    I had an external drive failure and had to buy a brand new drive.  I was able to restore my info onto a new drive, about 1.5 TB of data.  When I go to launch time machine now with the new drive connected and my backup connected, it treats the new drive as if it had different data and wants to create a whole new backup set when it should just append.  How do I get around this?
    I could just reformat the backup drive and start fresh again but would rather not do that if I can avoid it, just in case there were errors in copying etc.

    Hi
    I should have been more clear, sorry.  I work from a laptop.  I have 2 external drives - one for my projects which failed but has since been replaced and restored from a backup.   My 2nd external drive  is the time machine backup drive.
    When my project drive crashed, I bought a brand new drive and restored it using my time machine backup drive.
    Now the data exists on 2 drives - the time machine backup drive, and the new drive.  When I connect the backup drive now, it thinks my new drive has new data, probably since it is a new device/drive, and wants to do a brand new backup, when in fact the data already exists on that very drive.  It shouldn't have to back up all 1.5 TB when nothing has changed!
    Unless there is a way to tell time machine to simply append to the old backup, I think it will try and do a new backup (1.5 TB).  I'm thinking maybe I should just initialize my time machine backup drive now and start over so it is only one backup set of 1.5 TB instead of (2) sets of 1.5 TB!

    how to change my ipad passcode knowing that i lost my old one

    If you've forgotten your passcode then you'll need to connect the iPad to the computer that you normally sync to, and you should then be able to restore your content from your computer : http://support.apple.com/kb/HT1212 - you may need to put the iPad into recovery mode : http://support.apple.com/kb/ht1808

  • I cannot get on to my Apple TV.  I know that they are now requiring a one time security code?  What is it How do I find it?

    I know that they are now requiring a one time security code.  How do I find it?  Does anyone know what it is?

    There is no such code required to use the Apple TV. A user can setup a passcode to be required for airplay, and Apple ID is required for use of the iTunes store (or any other subscriptions associated with it).

  • HT1430 Since my iPhone 5 fails to accept calls randomly how is I am supposed to know that I missed a call and I know I need to reboot.  This "solution" is worthless.

    Since my iPhone 5 fails to accept calls randomly how is I am supposed to know that I missed a call and I know I need to reboot.  This "solution" is worthless.

    Standard steps from the user guide are to restart, reset then restore if necessary.
    Have you done those?

  • Started a similar string before.  When I select a recipient in Messages on my Macbook Pro the name shows up in red and says the recipient is no longer registered on iMessage.  I know that they are registered.  Is there a problem with Contacts?

    Started a similar string before.  When I select a recipient in Messages on my Macbook Pro the name shows up in red and says the recipient is no longer registered on iMessage.  I know that they are registered.  Is there a problem with Contacts possibly.  The previous help has been appreciated but the problem persists.

    Hi,
    Try iMessaging your own iPhone and see if your account is actually logged in.
    It can appear "enabled" and On line but sometimes it is not.
    Also try sending from your iPhone (number) to your Apple ID and see if it gets to the Mac.
    If it does not use the Sign Out button.
    Then shut down the Mac
    On restart add back the Apple ID to the iMessages account settings.
    I also just checked My wife's iPhone as she popped up red.
    It turned out her iPhone did not have Messages On.

    I think I'm not following you. In my opinion, PDFs can't be folded; and whether pages are in reading order or not cannot be changed by the free Reader.

  • How do I change system settings so that users are not required to enter the mac's admin pw in order to join a wifi network?

    how do I change system settings so that users are not required to enter the mac's admin pw in order to join a wifi network?
    Right now my macbook pro requires an admin password before connecting to a new wifi network. In other words when a user that is not an admin tries to connect to a new wifi network the pop up displays indicating that it is locked and an admin password is required.
    Is there a way to remove this restriction so that a non admin can connect to wifi without the mac's admin password.

    You can enable / disable this option in System Preferences:
    System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab > Require administrator authorization to: Change networks

  • I have created another iTunes library (so I have 1 for an ipod touch and 1 for an iPad), but the apps from the iPad appear in both libraries. How can I stop this so teh 2 libraries are completely separate please?

    I have created another iTunes library (so I have 1 for an ipod touch and a separate 1 for an iPad), but the apps from the iPad appear in both libraries. How can I stop this so the 2 libraries are completely separate? Thanks

    You don't need two separate libraries to manage two devices.
    I suspect the reason that the apps are appearing in both libraries is that you have enabled automatic downloads in iTunes and automatic syncing of apps so that all your purchases end up in both libraries, defeating your original aim.
    Why not use a single library and make playlists for the media content you want on each device? Disable Settings > Store > Automatic Downloads > Apps on each device, then connect each device in turn and turn off Automatically Sync Apps on the Apps page.
    You can now manage your devices independently, while only having to manage the content of one iTunes library, instead of two.

  • How do I know that there are double-byte characters in s String?

    Hi!
    If I have a String that contain English and Chinese words,
    How do I know that the String contain double-byte characters(Chinese words)?
    Following is my method and the problem I suffered...
    String A = "test(double-byte chinese)test";
    byte B[] = A.getBytes();
    if(A.length() != B.length)
    System.out.print("String contains double-byte words");
    else
    System.out.print("String does not contain double-byte words");
    If the String contains Chinese words,then A.length() will be smaller than B.length...
    I run the program on Window NT workstation(Tradtional Chinese version) and it works...
    Then I run the same program on Redhat 6.0(English version),
    but the result was not the same as running on NT...
    because A.length() always equal to B.length...
    I guess that's because of Charset of OS...
    But I don't know how to set the Charset of Linux...
    Does anybody have other solution to my problem?
    Any suggestion will be very appreciate!

    A String is always in Unicode. You cannot see what kind of character is in the string unless you compare with the Unicode range of charcters. E.g. 3400-4DB5 is CJKUnified Ideographs extension A. Then you at least know that is is not Latin-1 or other.

  • HT4972 I am in way over my head.  I have IPAD2...dont know what version software.  Dont know how to update...dont know that I have ever done so.  ITunes on PC.  Can you help

    In way over my head.  I have IPAD2...dont know what software version. Need to update...dont know that it has ever been done (owned device for 2 years).  Help?

    You can see the current version in Settings > General > About > Version. If it shows iOS 5+ then you should have a Settings > General > Software Update for direct update on the iPad, if it's iOS 4 then you can only update via your computer's iTunes.
    To update via your computer, connect the iPad to your computer's iTunes and copy any purchases off it to your computer via File > Transfer Purchases (File > Devices > Transfer Purchases on iTunes 11). You may also want to copy photos and any important documents off the iPad as well e.g. via the file sharing section at the bottom of the device's apps tab when connected to iTunes, via wifi, email, dropbox etc - they should be included in the backup, but it's best to have a copy of them outside of the backup just in case. You can then force a backup of the iPad by right-clicking the iPad 'Device' on the left-hand side of iTunes and selecting 'Backup'.
    Then start the update by selecting the iPad on the left-hand side of iTunes (on iTunes 11 you can enable the left-hand sidebar via option-command-S on a Mac, control-S on a PC), and on the Summary tab on the right-hand side clicking the Check For Updates button
    Updating to iOS 5+ : http://support.apple.com/kb/HT4972
    An iPad 2 will be updated to iOS 6.1.3, that is the only version that is 'signed' by signed for it

  • How to hold save operation till the workflow approvals are completed ?

    Hello,
    The requirement is that on change of certain fields in customer master , an approval workflow should trigger and only after the chain of approvals is completed the change in customer master should be saved.
    If standard provides the field eg in SWEC then its fine but otherwise is the following approach correct ?
    1. Find a suitable user exit on save action
    2. Determine whether the required field is changed or not using the std change history tables
    3. if yes, trigger a custom event for the business object which wud be already linked to workflow.
    that way the workflow will be triggered
    4. now trigger another custom event in the workflow after all the approvals are completed
    5. induce a wait for event for this approval-completed event in the user exit. so that till the time this event is generated, user exit processing is not completed (find if there is function module for wait event OR keep infinite loop)
    Is this approach correct because its complete 'home-made' design and doesnt look very good to keep the user exit waiting for entire workflow which mite extend to even several days.
    what should be the solution for this ?
    thank you
    B

    Hi:
    1. Find a suitable exit or BAdI on save action (even Enhancement point)
    2. Check whether the required fields are changed or not, if yes- then display an information message saying, "Approval WF process started for the customer: XXXXX". Then after displaying the information message, system needs to behave like as an error mesaage was showned.
    I mean, you need to come out of the current standard screen and the whole std. program (little bit tricky but it is possible to do), so we are not saving the data to database table.
    3. Then after all approvals in WF, use std. FM or BAPI to update database tables for the changed data.

  • ITunes indicates that I have already synced to 5 computer, but I haven't.  How do I let the computer know?

    I'm attempting to backup my iphone and both my computers indicate I have activated 5 computers and I must deactivate on to add one.  However, I have never synced my iPhone.  Help, please.

    There is an option to de-authorize all the computers. 
    The only other option is to go to each computer you have authorized and de-authorize each one.  If you are like me, and you don't even remember authorizing 5 computers the de-authorize all is the only option.
    Go to iTunes and login
    Click View Account after you login
    Account Information window - deauthorize all.
