Does anyone have vi's written to analyze Eye Diagrams? Extinction Ratio, Rise Time, Fall Time, Jitter

I have a 100Mb optical signal and I need to measure parameters given in the eye diagram such as Extinction Ratio, Rise Time, Fall Time, etc. 
Does anyone have vi's written to measure these type of parameters?
Thanks!!

TeleTech,
The Modulation Toolkit contains tools for developing and displaying eye diagrams.  I do not think that the parameters you are looking for are included, but you may be able to derive them using the available functions in the toolkit.  I will be sure to post any examples if I come across them.  I hope this helps!

  • Does anyone have a PPC mini that goes to sleep based on the timer?

    Problem is that my mini won't go into sleep mode per the set minutes on the system preferences energy pane. I've searched and read the other posts on this.
    Configuration is PPC mini, Apple USB keyboard, Microsoft intellimouse, and Eizo CRT display. No bluetooth or other hardware. Latest Microsoft mac mouse driver (had same issue without current Microsoft driver). Hardware test doesn't show any problems, and there's nothing to indicate any hardware issues. Latest OS X update was done with the combo updater. Have reset the power management unit (PMU). Have not called Apple yet.
    With the sleep settings set on the energy saver pane, I've tried detaching the keyboard and mouse, together and individually, and that didn't change anything. What happens is that the display will shut off at the appointed time, however, the mini won't enter itself into sleep mode. I can manually put it to sleep by clicking blue apple, sleep or by pushing the power button.
    I'm scratching my head on this.....so I don't take it personally, does anyone have a mini that does go into sleep as scheduled? Appreciate any suggestions on anything else to look at.

    Doug,
    I had already started along that path, by removing the Microsoft mouse driver (which didn't fix the problem). However, starting the system in safe mode was a good baseline, as it went to sleep as it should - confirming a software-related issue.
    I figured it would actually be easiest to shoot this bug by starting from scratch with an erase and install. After each tweak (ie, turn firewall on), software add (ie, clamXav), or update to the system, I tested it's sleep ability. And I found the bug/issue.....checking 'enable firewall logging' under the advanced options on the firewall tab, in the sharing preferences pane. No kidding. Stealth mode and UDP can be checked, just not firewall logging. Dunno why, however, the world is now at peace, able to sleep as needed.

    I have set up iTunes Match on only 3 devices (my Windows 7 desktop and 2 iPhones) and am now trying to authorise my new Windows 8 (Toshiba) laptop but I keep failing to authorise the laptop using my one-and-only Apple ID. Does anyone have advice to solve this problem?!

    Hi all.  I can’t tell you how to solve your iCloud 3.x issues.  Heck, I don’t think they’re even solvable.
    But if you had a previous version of iCloud that was working correctly then I can definitely tell you how to solve the “iCloud Photo Stream is not syncing correctly to my Windows 7 PC” problem.  …without even a re-boot.
    Log out of iCloud 3.0 and uninstall it.
    Open My Computer and then open your C:\ drive.  Go to Tools/Folder Options and click on the View tab.  Select the “Show hidden…” radio button and click on OK.
    Open the Users folder.
    Open your user folder
    Open ProgramData (previously hidden folder)
    Open the Apple folder – not the Apple Computer folder.
    Open the Installer Cache folder
    In Details view sort on Name
    Open the folder for the newest entry for iCloud Control Panel 2.x – probably 2.1.2.8 dated 4/25/2013
    Right click on iCloud64.msi and select Install.
    When finished, the synching between iCloud and your PC will be back to working perfectly as before the 3.0 fiasco.  The pictures will be synched to the same Photostream folder as before the “upgrade”.  Now all you need to do is wait until Apple/Microsoft get this thing fixed and working before you try the 3.x upgrade again.
    I think the iCloud 3.0 software was written by the same folks who wrote healthcare.gov with the main difference being that healthcare.gov might eventually be made to work.
    For those of you who hate to go backwards, think of it as attacking to the rear.  Which would you rather have, the frustration of no synching or everything working on an older version?
    Good luck…

    First, for the forum view issue. Go to My Settings (on the right) and in General Settings change the Topic Page View to Flat. Click Save. Posts should show up in the order they were written.
    Have you seen this?

    Also, since you said that you've gone through the 5 Rs, I would assume that you used the iPod Updater to restore (since there is no other way of doing it and you don't "run" the 5 Rs).
    When you restored, did you use the latest updater?
    You may also want to try formatting the iPod through Windows. Connect it to the computer and when it appears in My Computer right click it and go to format. Does anything happen? Can you format the iPod through Windows?

  • Does anyone have a LISTENER heartbeat script

    Instead of reinventing the wheel, does anyone have a heartbeat script that runs on Unix (HP-UX 11.0) and checks the status of the Listener (e.g., if the Listener is down, reload/restart)?? Many thanks in advance....

    This is a very basic script, just written for you on CS3 and totally untested:
    if (app.documents.length == 0){
        alert ("Please open a document, select an object, and try again.");
        exit();
    var myDoc = app.activeDocument;
    var myPage = myDoc.layoutWindows[0].activePage;
    var myPageId = myPage.id;
    var myDialog = app.dialogs.add({name:"Duplicate pages"});
    with(myDialog.dialogColumns.add()){
        with(borderPanels.add()){
            staticTexts.add({staticLabel:"Duplicate front-most page # " + myPage.name});
            var myIntBox = integerEditboxes.add({editValue:1, smallNudge:1, largeNudge:10});
            staticTexts.add({staticLabel:" times"});
    var myResult = myDialog.show();
    if(myResult == true){
        var myNumber = myIntBox.editValue;
        if (myNumber < 1) {
            alert(myNumber + " is invalid number.");
            exit();
        for (i = 0; i < myNumber; i++) {
            myPage.duplicate(LocationOptions.AFTER, myDoc.pages.itemByID(myPageId));
    myDialog.destroy();
    It duplicates the active (the front-most page) — its number you see in the bottom left corner of the document window. You can type a number or use up/down arrows to increment it by 1 (add shift key to increment it by 10).
    Hope it helps.

  • Does anyone have problems with data usage with att and Iphone5?

    Hello, Does anyone have problems with data usage or non usage I should say with Iphone 5 and AT&T?

    After 4+ months of dealing with this data usage and battery drain problem that included 3 data captures of my wife's iMac, the trigger for us regarding the problems syncing with iCloud, and 5 hours of logs off my iPhone 6 to be analyzed by Apple engineers that included times my wife's computer was both on and off to demonstrate the difference in data usage and battery drain under those conditions, I can say with very reasonable certainty that the iOS 8.3 and corresponding Mac OS 10.10.3 update has solved the problem. 
    We have now been running for about 2 weeks and data usage with the iCloud Servers attempting to sync has dropped from a rate of 31 GBs to under 15 MBs per month.  Yes, you read it right.  We were burning 2000 times as much data doing absolutely nothing important on both of our phones, a 5s and a 6.  Just imagine what that does to battery life!  The 5s would last about 5 hours and the 6 was dead in less than 14.
    The distasteful aspect of this process was how the engineers were quietly fixing the problem at the same time sending messages to my contact person within Apple that were dismissive in nature in the face of indisputable unreasonable results. I must say, this experience with the multiple times the engineers' responses were inappropriate put a little tarnish on the old Apple shine of the ‘It just works’ mantra. This was my first experience in 34 years that caused me to stop recommending Apple products without reservations and with a disclaimer.
    Since the update solved the problem, then I can only conclude that there was a logic bug regarding the reaction within the process to the incoming data that was corrected.  There was noting short of logging out of iCloud that circumvented the problem for us, Gator5000e and probably many others noted on other threads.  I am not trying to imply that this is the cause of everyones battery use problem, but it is reasonable that it was a cause for many.

    I recently bought, from the original website of Adobe, Photoshop elements 13. However, when I go with my mouse pointer over the menu, It hangs or he works very slow. Does anyone have an idea how I can fix it? I have already downloaded updates, both from Adobe and Windows. I have a new pc with window 8.1.

    It could be a coincidence, but I rebooted the machine and (knock on wood) PSE13 seems to be working ok.
