Amplitude measurement using "Tone Measurement" when monitoring amplitude of a waveform

Exactly how does Labview make the amplitude measurement using "Tone Measurement" when monitoring amplitude of a waveform?
What is the mathematical operation that Labview uses to make an amplitude measurement when using "Tone Measurement" function?
Thank you!

  • #UNAVAILABLE error in measures when using substr() in BO XI 3.1 SP3

    Hi All,
    I'm using BO XI 3.1 SP3 with Essabse 11 for OLAP Connection.
    I got #UNAVAILABLE value for database delegated measures when using substr() on the dimension.
    The aggregation function have to be database delegated because the measure need to be calculated again in aggregation level, such as MOM (month on month) and YOY (year on year) etc.
    Can someone help to solve this problem?
    Regards
    Sofian

    Hi, Sofian!
    We also are trying to work in XI 3.1 SP3 with Essbase as data source.
    As I understand there is no support for any essbase mdx/xmla calculations or functions in universe.
    In document called "OLAP universes - best practice" are given some examples for SAP BW and MSAS only.
    With Essbase OLAP source I can't even make simple measure like Measure1+Measure2, @Select doesn't work too.
    All I've reached in this field - creating filters, prompts and LOV-dimensions with restricted number of levels in hierarchy (by filter in Where part.
    But the main problem for us is - YTD calculations.
    In our Essbase it is dynamic calculated objects, so I need to use Y-T-D function to use it.
    Also we want to use Level-based, not Gen-based, ordering dimensions, but I didn't find any information about it
    Did you find some examples, documents or reviews in this area?
    Now, it seems like there is no any big project BOE+Essbase in the world...

  • HELP Make Settings for Units of Measurement for Monitoring of Consumption

    Hello All:
    I just cant' define an unit of measure to stablish consumption calculation. I know how to make all the other settings, but I just can't stablish the unit of measure to use in there.
    Could please somebody gime this explanation ? Step by step ?
    I've read that are preconfigured units of measure for examplo MPG miles per gallon US but I will use Kilometers per litre.
    I want to know how to create this unit
    how to link it with an existing SI group
    So I can use it in the step Make Settings for Units of Measurement for Monitoring of Consumption
    thanks in advance
    Luis Henrique

    Dear Luis,
    Please use CUNI t code for creating unit of measurement. Please follow any exist Unit of measurement and replicate the same. This is a configuration so will have transport requirement

  • [svn] 3189: Accepted patch supplied in SDK-16641 and SDK-16643 to fix bad text measurement when the textIndent style is non-zero (as reported in SDK-16454 and SDK-15558).

  • How do I ensure mail is sent from the correct email account?  I have two set up on my iPad, and it seems to choose which one to use somewhat randomly.  This has happened both when using Mail and when emailing form another app.

    I have two email accounts set up on my iPad -- one I use &amp; one I monitor for a disabled person.  On several occasions, mail I have composed and sent from my email account was sent showing the other account as the sender.  This has happened both from within Mail and when emailing from other apps, such as Safari, Photos, etc.  Any idea what is going on and how to prevent this from happening?

    Are you confirming your POP account is selected as the sending email account before the message is sent?
    And regardless if the email is a new email or is replying to or forwarding an email received by the POP account and cofirming the POP acconut is selected as the sending email account, the message is sent by the Gmail account?
    All message sent by the POP account are sent by the Gmail account?
    If so, delete the Gmail account from your iPad and test if a message sent with your POP account which will be the only email account available with the iPad's Mail app is recieved from your POP account/address.
    If not, something else is wrong or on play that has nothing to do with the iPad.

  • My macbook 2008 screen went black a few months ago. I've been using it with a monitor. Today it's working. I have a feeling it's going to die at any time. Is it possible that a software patch fixed this ? Is there a utility I can run to test the screen ?

    Model : Macbook 2008
    Symptoms: The screen was, intermittently, going black last year and then went black completely. I have been using it on a monitor ever since.
    I can see the screen with a flashlight.
    I completely erased the drive and loaded OSx 10.7. I believe that's the last version of OSx Mac will be supporting on this computer.
    When I booted up the computer this morning the screen came on !
    While typing this question, my screen went black again, not to return.
    So sad.
    I did bring it to Apple and they believed the entire screen needed to be replaced.
    They say that they tried a new inverter and it didn't work.
    I have a feeling I'm just out of luck unless I want to cough up the $300 to fix the screen.
    Although it is a solid machine, 2Ghz processor with 4 gigs of ram, it is still six years old.
    I imagine that's like putting a new transmission in a 95 Honda civic. Yeah, it's a reliable car but it's old and it's probably going to break again.
    I love my mac so much but I can't justify buying a new one or  paying to fix this old one.
    I have a Gateway dual booting Windows 7 and ubuntu linux that's actually pretty slick and has taken it's place on business trips and coffee shop excursions.
    If anyone has any thoughts or feedback I'd appreciate it.

    The current Apple hardware warranty provides the following coverage for replacement parts:
    A replacementpart or product, including a user-installable part that has been installed in accordance withinstructions provided by Apple, assumes the remaining warranty of the Apple Product orninety (90) days from the date of replacement or repair, whichever provides longer coveragefor you.
    Check your particular warranty and see where you stand as to the period of coverage.
    Good luck,

  • I can no longer add music to my phone after using tones

    I got a new iPhone 5C and I am trying to make tones for it.  I used an app to make a tone and when I enable Synching Tones All Tones I can no longer add music to my phone through iTunes.  When I try to drag and drop a music file the icon has a red circle with a line through it. 

    Hello Skymeck,
    Welcome to Apple Support Communities.
    Here are a couple of threads from the Communities that explain how to add tones to your phone. You might want to review them to ensure you are adding them correctly and not getting in the way of syncing music.

  • How to make use of AM Pool Monitor

    Hi,
    I get Java.lang.OutOfMemory when i run my OA application depoyed in the server.
    (It works fine for 5 to 6 rounds of testing.next time when i access the page I get the error)
    Oracle FAQ answer suggests to make use of AM pool Monitor.
    What is this AM Pool Monitor.
    How can I use it?
    Thanks,
    Gowtam.

    Enabling AM Pool allows re-use of AM objects thus saving creation of new AMs and consuming less JVM memory.
    To enable AM pooling you need to set the profile FND: Application Module Pool Enabled value to "Yes".

  • T420 can't use dual DVI connected monitors

    I have a T420 connected to The ThinkPad Mini Dock Plus Series 3 - 90W (433810U* - United States), DVI port 1 connected to monitor and VGA connected to second monitor using extended desktop.  This configuration works fine but when I hook up both DVI ports to my monitors only one of the screens work and in the Intel Graphics  and Media Control Panel only shows one monitor. I have 2 different cables 1 DVI-D dual-link and 1 DVI-D single link, the dual-link works with the VGA setup but with the 2 DVI connections only the monitor with the single link cable works.

  • Using Expose on external monitor only?

    Hello All,
    I have 2011 mbp that i sometimes use with an external monitor, with the monitor being my only display (closed clam-shell mode). I encountered a problem where the hot corners do not work? for some reason only the upper left corner works on the external display. if i use hot corners on my laptop screen, all the corners work? (I am not sure if this is relevant to solving this issue, but I use a wireless mouse when i use my external display.)
    How do i fix this so that all the corners work as hot corners in expose on my external monitor?
    Thank-you,

    We went through a similar discussion with the placement of the Dock with multiple displays, and found by experiment that the dock is placed on the specified edge of the main display (bottom, left, right), unless that edge was extended by an adjacent display along that edge, in which case the Dock was placed on the edge of the Extended Desktop.
    I think Capt Fred is saying something similar for this as well.

  • I can not download any files using Safari ? when I choose to download application file the URL include the file name and stop responding. Any help??

    I can not download any files using Safari ? when I choose to download application file the URL include the file name and stop responding. Any help??

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box.
    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem(s)?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault in Mac OS X 10.7 or later, then you can’t enable the Guest account. The Guest login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    *Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
    Test while in safe mode. Same problem(s)?
    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

    I have 9" classic ipad. may i connect ipad to separate 21" monitor and use it as main monitor?

    The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
    You would need to find a 3rd party dispay extender app to accomplish this. The results may or may not be acceptable to you.

  • Hi there, can anyone tell me how to make make Garageband ignore HDMI as an audio output-device on a 2013 Mac Mini? Now it keeps on prompting me: Do you want want to use the HDMI device (monitor without audio) for audio output? Thanks in advance, Grtz T.

    Hi there,
    Can anyone tell me how to make make Garageband ignore HDMI as an audio output-device on a 2013 Mac mini i7 using an Apogee jam as an input for bass and a Behringer USB DAC with RCA audio output? Now it keeps on prompting me: Do you want want to use the HDMI device (monitor without audio) for audio output? I'm also suffering massive audio lag issues with the Apogee jam after waking the mini from sleepmode, wich pretty much renders it useless.
    Thanks in advance,
    Grtz T.

    I think the easiest way to do this is to have the EyeTV app running in one user account and sent via HDMI to the TV, and use a separate user account for Screen Sharing. Both logins can be active at the same time and with Lion you can connect via screen sharing to which ever login you need.
    With regards to the Mac video resolution changing, when it is not the current input on your AV receiver. This is 'normal', if the Mac sees no signal it drops down the a lower level. What you need is to buy a HDMI Detective Plus which tricks the Mac in to always seeing a signal and hence it will not drop down the resolution. See http://www.gefen.com/kvm/dproduct.jsp?prod_id=8005
    The Mac mini does have an IR receiver. This can be used with the EyeTV app, iTunes, and similar. Yes I believe EyeTV would run for prolonged periods quite happily, it is has been around for a long time and had most of the rough edges polished off. However one issue you will have to deal with is that it does not automatically update its program guide data. For this you might have to write or modify an AppleScript. Elgato support or their user forums will be a lot of help.
    You can set EyeTV to convert recordings to an iTunes (Apple TV) compatible format and then delete them from EyeTV.
    The HDMI Detective should solve your handshaking problems.

  • Recover Vista 64-bit OS using only an external monitor

    How can I use HP System Recovery to reinstall the Vista 64-bit OS using only an external monitor?  Unfortunately the display on my HP Pavilion DV5-1000US is broken.

         Thanks for suggesting use of BIOS messages as an indicator of recovery success using an external display.  Currently all my BIOS messages go to the internal display, which is broken.  Therefore, I do not know what information those messages present.  How can  I direct the BIOS messages to the external display?
         I have located the HP Recovery Disks I made when the computer was purchased.  Thanks for reminding me about them.

  • FP-module don't use new *.iak when changing to iak-file on runtime

    Hi folks,
    I'm using FP1001 (RS-485) communication modules with a bank of FP-AI-110
    (8 x AI) and FP-SG-140 (8 x StrainGauge) with LabVIEW 6.1.
    Since I need to change input ranges of the modules on runtime
    (autoranging feature) and there is no vi to manage this, I created a
    couple of iak-files with the FP-explorer (V3.02, build 177), where I set
    the approbiate input ranges. My application then monitors the analog
    input data of the modules and changes the used iak-file as needed to
    prevent over- and underranging.
    When changing the iak-file the current session is closed (FP-Close) and
    the next session is opened with FP-Open and Create Tag, continuing with
    FP-read.
    My application does its' job well, since I monitor the currently used
    iak-file, range and the fact that sessions get closed before opening the
    next, but the FP-modules won't restart using the new range settings,
    after the following session is started with the other iak-file. The
    modules allways keep the previous settings.
    So whats wrong?
    Btw.
    I noticed FP-Explorer also has its problems changing module- ranges,
    after loading a new iak-file.
    So I startup the FP-Explorer with a iak-file for a low range setting
    (module input range) and increase the input voltage at the module input
    just as much that a overrange occurs. Then I load another iak-file with
    higher range-settings. FP-explorer shows the higher range in its range
    column, but when monitoring the module input values, overrange is showed
    first. After restarting monitoring, the input values are showed
    correctly.
    Heres' the problem:
    Loading the previous iak-file again, the overrange should show again,
    since the input value was left at the higher value, as set before. But
    no overrange shows! FP-Explorer monitors the higher input value which
    istn't within the input range, showed in the range column.
    So FP-explorer hasn't switched down the modules range!!!
    Restarting monitoring, or reloading the iak-file doesn't change
    anything. Restarting the FP-explorer shows overrange again when starting
    to monitor values. Restarting monitoring lets the FP-explorer continue
    to monitor the higher input value, which is above the range showed in
    the range column.
    The only thing which helps all the time, is to open the devices context
    menu, then to click on "Edit this device", and click on channel
    configuration. Then a pop-up window asks which setting to use (file or
    device). If I click on file, all the settings of the current used
    iak-file are used correctly.
    Ciao,
    Rainer

    Rainer,
    The FieldPoint IAK File is used in application programs (e.g. LabVIEW, LabWindows/CVI, OPC) for channel names, handle information and scaling information. FP Open.vi launches the FieldPoint Server with the specified IAK file, and uses the information in the specified IAK file for scaling (serial modules require scaling on the computer, ethernet modules scale the data in the network module) but does not re-configure the IO modules according to the IAK file. Likewise, opening an IAK file in FieldPoint Explorer does not reconfigure the IO modules to match the IAK file. The only times that settings are synchronized between the IAK and the modules are when a)the Find Devices command is issued (config from modules loaded), b) the Channel Configuration wi
    ndow is opened (file or module config can be choosen) or c) a Snapshot command is issued (current settings of modules are stored).
    Currently, the FieldPoint Server VI's do not allow dynamic re-configuration of ranges. If you wish to dynamically reconfigure your module ranges, you will need to use the FieldPoint Optomux VI's, which are located under the RT sub-palette of FieldPoint. They are installed by default only if you have LabVIEW RT, so you may need to re-install FieldPoint Explorer (custom install) to get them. For more information on the Optomux commands, please see the FP-1000/1001 Programmers Reference Manual.
