Multiple amplitude readings on the same waveform

I have a waveform with two distinct amplitudes on it.I can
read the waveform and make a single amplitude measurement based on the
amplitude measurement off of the scope but  I need to be able
to measure both amplitudes, the sub
VIs i was planning on using to do this arent in the 8.0 base version im
running. Does anyone have any suggestions on another way to do this?
*Edit*Im reading in data from a Tektronix TDS scope

I don't have any of the TKTDS vis, so it doesn't make that much sense to me.  However if you pull out the 1D array of Y values you can do a brute force search for local maxima and minima.  I am sure there are more eligant was to accomplish this,  but this is the best I could do off the top of my head.  It returns an array of likely amplitudes, it would be up to you to figure out how to separate the "high" ones from the "low" ones.

  • How do I add signals from different modules to the same waveform chart?

    When using build array to connect signals from different FP modules to the same waveform chart, the array type is not the same as if all the signals come from one Read Array. Only one digital indicator on the chart displays with the build array method. Why

    Hi gencell,
    There are two ways to plot multiple plots on a Waveform Chart, a 2D array and a cluster of doubles or integers. I would suggest that you use a Bundle to create a cluster.
    This information is in the Context Help of the Waveform Chart terminal (from the Block Diagram).

  • What happens on iCloud (ex. contacts) when multiple family members use the same Apple ID?

    What happens on iCloud when multiple family members use the same Apple ID?  For example if we all choose to use iCloud for contacts, are they all merged together?  We use the same Apple ID so we can use find my iPhone to keep track of the whole family.

    Of course if you are both connected to the same iCloud account you have the same contacts - what did you expect?. The contacts live on the server and are read from there by the devices; so as you've both managed to sync your contacts up to iCloud they are now inextricably mixed. You can only delete your contacts by deleting individual ones, and doing that will delete them from your phone as well.
    You can only unravel this by
    1. In the iCloud contacts page at http://icloud.com, select all the contacts, click on the cogwheel icon at bottom left and choose 'Export vCard'.
    2. Sign out of System Preferences>iCloud
    3. Create a new Apple ID and open a new iCloud account with it for your own use.
    4. Import the vCard back into the iCloud contacts page.
    5. Go to http://icloud.com and sign in with the original ID. This is now his ID. Work through the contacts individually deleting the ones you don't want him to have. When done sign out and advise him to change his password.
    6. Go to the new iCloud account and delete his contacts individually.
    Of course if you have also been syncing calendars and using the same email address there are problems with doing this.

  • How do I use multiple local workspaces for the same website in VS2013?

    For quite some time I've been using VS2010 with multiple workspaces mapped from the same TFS branch to test different variants of a website in parallel. The internal web server (Cassini) seems quite happy to run multiple versions and simply maps a new port
    number for the second and subsequent instances that start up.
    We are now looking to move to VS2013, so have to use IISExpress since the 'internal' web server is no longer provided.
    How do I configure things so that if I open a single workspace, IISExpress runs against that workspace using the default port number (specified in the solution), but if I open a second instance in a different workspace it correctly uses a new port number
    and working folder. Do I need to invoke IISExpress using the command line (presumably from each workspace) and specify the relevant defaults or is there some way to enter this in the local config file for IISExpress?
    My initial attempt at editing to config file resulted in the 2nd and subsequent instance using the same physicalfolder as the first instance, presumably because the speficied site name and port number are the same!

  • How to load multiple HTML5 canvas on the same page (the proper method)

    Hi,
    I've been struggling to load multiple canvas animations on the same page. At the beggining I thought that exporting the movies with different namespaces and reloading the libraries in a sequential flow might work, but it doesn't. It always loads just the last animation loaded. More info here: Coding challenge: what am I doing wrong?
    Here is a sample of what I'm doing:
    1st: Publish two flash movies with custom namespaces for "lib" set in the "publish settings": "libFirst" and "libSecond".
    2nd: Edit the canvas tags in the HTML page. One called "firstCanvas" and the other one called "secondCanvas"
    3rd: Edit the javascript like this:
            <script>
                // change the default namespace for the CreateJS libraries:
                var createjsFirst = createjsFirst||{};
                var createjs = createjsFirst;
            </script>
            <script src="//code.createjs.com/easeljs-0.7.1.min.js"></script>
            <script src="//code.createjs.com/tweenjs-0.5.1.min.js"></script>
            <script src="//code.createjs.com/movieclip-0.7.1.min.js"></script>
            <script src="{{assets}}/js/first.js"></script>
            <script>
                function initFirstAnimation() {
                    var canvas, stage, exportRoot;
                    canvas = document.getElementById("firstCanvas");
                    exportRoot = new libFirst.first();
                    stage = new createjsFirst.Stage(canvas);
                    stage.addChild(exportRoot);
                    stage.update();
                    createjsFirst.Ticker.setFPS(libFirst.properties.fps);
                    createjsFirst.Ticker.addEventListener("tick", stage);
            </script>
            <script>
                // change the default namespace for the CreateJS libraries:
                var createjsSecond = createjsSecond||{};
                var createjs = createjsSecond;
            </script>
            <script src="//code.createjs.com/easeljs-0.7.1.min.js"></script>
            <script src="//code.createjs.com/tweenjs-0.5.1.min.js"></script>
            <script src="//code.createjs.com/movieclip-0.7.1.min.js"></script>
            <script src="{{assets}}/js/second.js"></script>
            <script>
                function initSecondAnimation() {
                    var canvas, stage, exportRoot;
                    canvas = document.getElementById("secondCanvas");
                    exportRoot = new libSecond.second();
                    stage = new createjsSecond.Stage(canvas);
                    stage.addChild(exportRoot);
                    stage.update();
                    createjsSecond.Ticker.setFPS(libSecond.properties.fps);
                    createjsSecond.Ticker.addEventListener("tick", stage);
            </script>
    <body onload="initFirstAnimation(); initSecondAnimation();">
    Could someone please reply with the best practice on how to do this? If possible, without the need to reload all the libraries...
    If I only need to show one flash movie at a time, would it be more efficient to cut & paste the canvas tag using jQuery in the DOM and reloading a different lib on it?
    Many thanks!
    #flash #reborn

    I was able to fix it. At the end, it was easier than I thought. Just have to publish using a different "lib" namespace for each movie, load all the scripts at the end of the <body> and then add the following to the onload or ready events:
    $(document).ready(function () {
            var canvas, stage, exportRoot;
            // First movie
            canvas = document.getElementById("firstCanvas");
            exportRoot = new libFirst.first();
            stage = new createjs.Stage(canvas);
            stage.addChild(exportRoot);
            stage.update();
            createjs.Ticker.setFPS(libFirst.properties.fps);
            createjs.Ticker.addEventListener("tick", stage);
            // Second movie
            canvas = document.getElementById("secondCanvas");
            exportRoot = new libSecond.second();
            stage = new createjs.Stage(canvas);
            stage.addChild(exportRoot);
            stage.update();
            createjs.Ticker.setFPS(libSecond.properties.fps);
            createjs.Ticker.addEventListener("tick", stage);
            // Third movie
            canvas = dument.getElementById("thirdCanvas");
            exportRoot = new libThird.third();
            stage = new createjs.Stage(canvas);
            stage.addChild(exportRoot);
            stage.update();
            createjs.Ticker.setFPS(libThird.properties.fps);
            createjs.Ticker.addEventListener("tick", stage);

  • Can multiple people post on the same shared photo stream?

    Is there a way to have multiple people post on the same shared photo stream?
    My cousin would like to have a single shared photo stream where we can both post photos on it and comment, instead of having two separate shared photo streams. 
    We think that there should be an option for the album creator to give access to anyone he/she shares it with to enable them to also post pics on the same stream.

  • Can multiple APEX application use the same parsing schema?

    Hi,
    I have 4.2 APEX thru pl/sql Gatewat, 11gr2 DB and using theme 24.
    Due to the APEX limitation for version control I would be splitting 1 big ERP applications into 24 different APEX applications and each application would be considered as 1 unit for version control.
    I have about 800 tables and I would assume that all of these would need to be stored in 1 schema since a lot of these table are linked thru FK.
    Can I have multiple APEX APPS using the same parsing schema? or is there a better way to do this?
    Thanks in advance!

    Hi,
    Multiple applications can have same (one) parsing schema.
    You can test that on e.g. apex.oracle.com, where normally you have only one schema and you create multiple applications and all use that same schema.

  • Multiple profiles/users on the same device

    Hi there,
    I know that iOS is a single user environment.
    But, I am currently working in an enterprise environment and I was wondering if it was possible to have several profiles on the same device, maybe using certificates or so?
    Thanks for your help
    Cheers,
    Pierre.

    It would seem that unlike previous iOS devices the iPad and possibly AppleTV call for the ability to enable multiple profiles/users on the same device.
    I would suggest that if this capability is not on the roadmap for iOS by now then there is a least one place where alternatives to the iPad will have a major advantage.
    The thought they I would have to buy multiple iPads one for myself, my wife and my child because of a software constraint is untenable from a ecological standpoint (all these devices end up as landfill) let alone the economic one.
    Also as I use the iPad I see it's potential to become as important computing platform to me as my laptop eventually surpassing it. In this light I can't see how it could remain just a personal device.

  • Multiple disconnected users on the same laptop

    Has any open come across the following requirement? I have a customer that is interested in 'sharing' laptops with multiple offline users with the ability to sync. Can we have multiple disconnected users on the same laptop? If so what would be the options? The challenge is how to manage multiple extracts on one MWC installation. I suspect that 'OOTB', we only support one extract per machine/installation of the MWC. We may be able to support multiples, but it would take some config/customization.

  • Multiple iTunes Accounts on the Same Computer

    iTunes states that you can have multiple iTunes accounts on the same computer. But when I attempt to put in a new user account (for my wife so she can have her own music library) my own iTunes account pops up when I go to load iTunes while in her user account. And if I create any account that is NOT an 'Admistrator' account iTunes refuses to install itself as the "user does not have the privileges - consult your Administrator". So I am lost as to what I need to do to create separate iTunes accounts where each person has their own iTunes library and thus their own music. Perplexed...

  • How do i set up multiple iCloud accounts on the same mac?

    how do i set up multiple iCloud accounts on the same mac?

    Interesting - I was sure I'd seen a note somewhere that it was only Mail, but this article:
    http://support.apple.com/kb/ts4020
    does say
    Your secondary iCloud accounts can be set up and viewed in Settings > Mail, Contacts, Calendars on your iOS device, or Apple () menu > System Preferences > Mail, Contacts, Calendars on OS X Lion. You may choose to do this if you have a second iCloud account and need to access its Mail, Contacts, or Calendar data. 
    Note: While you can configure multiple iCloud Mail accounts in iOS, Push mail will only work for the primary iCloud account in iOS. Secondary account(s) will check for mail based on the settings in Settings > Mail, Contacts, Calendars > Fetch New Data.
    It's not something I can test - I suppose the second account's data gets added to the lists in iCal and Address Book?

    I have multiple album titles of the same name with different artists. How can I get them to go under one album title again?

    In iTunes(on a Mac or PC) just tap on 'Albums' rather than 'Artists' and you'll see them all together.
    You may find that there are songs mislabelled. In which case right tap on the Album or Artist and tap 'Get Info', then change to the correct name and the songs will join the rest of the songs for that Artist or Album.
    Then resync with your iPhone and all will be well.

  • How to prevent multiple users from updating the same data in coherence

    Hi,
    I have a Java Web Application and for data cache am using coherence 3.5. The same data maybe shared by multiple users which maybe in hundreds. Now how do I prevent multiple users from updating the same data in coherence i.e. is there something in coherence that will only allow one user a time to update. If one user is in a process of updating a data in coherence and some other user also tries to update then the second user should get an error.
    Thanks

    I have a question on the same line. How can I restrict someone from updating a cache value when I a process is already working on it. I tried locking the cache key but it does not stop other process to update it , it only does not allow other process to get lock on it.
