• Problem with the generation of multi-sinus wavefrom of random phase using PXI-5412

  Hello

  I am trying to generate random phase multi-sine waveform using the PXI-5412 14 bits 100 M/s AWG on LabVIEW8.0.

  The version of LabVIEW8.0 for the PXI-5412 comes with a sample VI on multi-tone waveform generation. When I tried with a different combination of frequency and amplitude, there is no problem with the sample VI.

  Because I need the phase to be random for each frequency component, I had tore the tone cluster containing 3 elements, i.e. frequency, amplitude and phase, which feeds the generator of signals, and rebundle the cluster with elements of reading a CSV file by using a loop, a fixed value amplititude and a number of random phase of the frequency generated by a random number (formula lournies elements (: pi - 2pi x r). When the waveform multi-sinusoidale generated on the PXI-5112 100 MHz Digital Oscilloscope, it was pointed out that the waveform would change with the tested frequency range.  However, the amplitude of the wave is always ~1.4V (guess that's always default to 1 V x sqrt (2)).  There is no question also when testing the same combination of frequency and amplitude by using sample VI without modification.

  Please find attached the VI of the sample, snatching up to the version and the CSV file I used. Is there something wrong with the table 1 d of the cluster of 3 elements that I built and assembled causing the signal generator to ignore the value of input amplitude and, possibly, the input value of the same phase (as it seems that the amplititude is always set to the default)?

  The other question that I found on the two sample VI and ripped version is on the news of sampling.  The waveforms appear on digital Oscilloscope PXI-5112 always default to 10 cycles no matter how changed the sampling frequency and the number of samples.  For example, if the frequency is 10 Hz, sampling frequency is 1000 Hz, and I put the number of samples to 10000.  I'm supposed to get 10000/100 = 100 cycles.  However, I could see 10 cycles no matter how, I changed.  What should be the correct way to change the number of cycles?

  Really appreiciate your help and advice. Thank you.

  1 phase unit is in degrees (-180 to 180), no - pi pi.
  2 standardize Waveform.vi always normalize your amplitude of the signal. You can remove it to use your desired amplitue, but must make sure that it is not above 5412 spec.

• Problem with the generation of two internal counters pulse trains

  Hello

  I do a control of temperature for two heaters, OR 9472 (output module digital), NI 9271 (RTD for measuring temperatures) and cDAQ-9174 chassis. So, I use the internal meter NI 9174 to generate two pulse train on the outputs (I tried with both cases-> pulse continuous and finite). Before that, I have two separate PID.vi, in which each sent the percentage of cycle of obligation for the two tasks of pulse generation (I configured these tasks with the physical channel cDAQ1Mod1/ctr0 and cDAQ1Mod1/ctr1). The problem is when I run the program, because the application initially worked fine, but after a few seconds the communication between the chassis and the application is not respected (no error message, but the external LEDs on the NI 9472 module had been disabled and stopped too NI 9271 module temperature readings). Then I tried to stop it with a 'Stop' button, but nothing happens. After, I abandoned the race and still nothing happened. So, I finished the Labview program with the Task Manager and a message appeared "reset VI: xxxxx". Finally, I have to restart my computer to run the program again. Can anyone help with this please? If you need more information, let me know.

  Kind regards

  Hi Luis,.

  I have the error cluster connected. But I solved my problem in a different way. I don't know why, but when I configured my RTD module with the DAQ assistant to test some of my design in a new file in VI, the RTD module works fine, but if I copy the entire program logic (include my DAQ assistant) back to my main VI folder and run the application, only for communication between my DAQ hardware and my software works there shortly. So I solved my problem set up any device or module in the same file from the application again and problem disappears.

  Thanks for your help.

• Problem with the generation DB sequence by clicking on the button apply

  Hi gurus,

  I created the page used as in the example of the box tools tutorial, but I want to put the employee so he used to number id generation lost the sequence number when the Cancel button is clicked.

  So instead of the code in the EOImpl Create method

  public void create (AttributeList attributeList) {}

  Super.Create (AttributeList);

  Number of empnum = getOADBTransaction () .getSequenceValue ("FWK_TBX_EMPLOYEES_S");

  setEmployeeId (number);

  }

  I do in the method of setEmployeeId of EOImpl

  {} public void setEmployeeId (numeric value)

  If (value == null) {}

  value = getOADBTransaction () .getSequenceValue ("FWK_TBX_EMPLOYEES_S");

  }

  setAttributeInternal (EMPLOYEEID, value);

  }

  but whenever the button click apply, I got following messagenumber - in EmployeeAM.EmployeeCreateVO1 EmployeeId attribute is required.

  I have try to disable the validation server with the following code in the PR, but obtained following the message "EmployeeId attribute in EmployeeEO is necessary.

  OASubmitButtonBean applybutton = (OASubmitButtonBean) webBean.findChildRecursive ("Apply");

  applybutton.setServerUnvalidated (true);

  Thanks in advance,

  efends

  Hello

  Uncheck the required property for EmployeeId.

  When the user click to button apply. get the current line for the view and set the EmployeeId filed.

  You don't have to crush create method in the java file entity oject impl.

  You need to write a method in the file java application module.

  public void setEmployeeId {
    XxVo vo = getXxVO();
    Row currentRow = vo.getCurrentRow();
    currentRow.setAttribute("EmployeeId", getOADBTransaction().getSequenceValue("FWK_TBX_EMPLOYEES_S"));
  }
  

  Call this method from the application process when the user has clicked on apply.

  Kind regards

• I have a problem with the simulation in Matlab 6.5 and LabVIEW for PID controllers

  I have a problem with the simulation in Matlab 6.5 and LabVIEW. I have a few methods for granting regulators PID in MATLAB to go but not of LabVIEW. Degree of international teams of two transfer but when I passed to the fourth degree is no longer working. We have changed the formula to calculate the parameters for the fourth year and gave me some good values for assignment of Matlab, but when I put on LabVIEW are not resolved. the formulas are available in PDF format and are. Please help me and me someone if possible. Thank you
  Lim.4 generation in comparison methods and the MATLAB program settings are for the service of transfer to the second degree.

  Hello Lascarica,

  I noticed that you are using the screw of PID. Gains on these screws are based on TIME instead of GAIN. You should be able to build a PID regulator and vary the gains and then compare the results.

• Problem with the Package Windows Installer... when trying to install ITUNES 9.2 and Quicktime.

  I bought an IPHONE 4 yesterday.  For more than 7 hours, I tried everything to download ITUNES 9.2.  I get the same error.  I spoke with apple as Microsoft.  I didn't PAY to get assistance from Microsoft yet and I hope I don't have to.

  Error: problem with the Windows Installer Package.  A program required for this install to complete could not be run.  Contact your provider to support personal or package.

  I have Windows XP.  I uninstalled and re-installed Safari and which did not help (at one point, I had problems with Safari).  I also have at one point received an alert on 'applesync.notifier' could not be executed.

• What is the problem with the tool crop of Photoshop CS6? (photo included)

  Since I upgraded to Photoshop CS6 and started to use the new crop tool, I get this very interesting visual error and some artifacts.

  I have the problem with the crop tool in previous versions of Photoshop.

  What can be the problem?

  

  Looks like a GPU problem. You can try to go in Photoshop preferences, disable the GPU acceleration and try if that fix it?

• Anyone having problems with the new iPhone LTE connection 7 on Verizon?

  I am now on my iPhone second 7 with Verizon. I had four phones for me and my family. I have now had issues where I have no signal in the same areas where my signal allows to be strong. I can't solve the problem with the activation/deactivation of the airplane and then mode again in normal mode. My phone will rest with no signal for 5 minutes, then going to LTE with three bars. I also had the problem where I had only 1 x signal, while my son standing right next to me has LTE. And he had the same questions, where I'm on LTE and it gets no signal. I use to have LTE where I live and work all the time, now it's spotty at best. Apple has replaced me and my sons iPhones but not luck. Still do. Any ideas or an any other suffering?

  (1) go to settings/cell phone/cellular data Options/enable LTE and select ONLY the DATA. This seems to solve the problem (as a temporary solution) for most of the people affected by this problem. The bad part is your request might not be as clear (since they cannot use the highest LTE signals) and you can make calls and data at the same time. But it does not solve the issue.

  (2) there are rumors (but you didn't hear that from me that we only are not supposed to discuss beta software program Apple in this forum) that the new version of Apple Beta for iOS (which also includes an update of the software carrier Verizon to 26.0) seems to solve this problem. So, there's a light at the end of the tunnel.

• Sierra Siri, «I have some problems with the connection...» »

  Guys,

  I just installed Sierra on my MacBook Pro (retina, 13 inches, early 2015) version 10.12. I can't get Siri at work, the app tracks, he hears what I'm saying, but after awhile, he returns with two messages, both on the screen and verbally "I have some problems with the internet connection. Please try again in a moment. "&"Sorry, I'm having problems with the connection. Please try again in a moment. »

  Any ideas?

  Thank you

  N

  It's a network problem.

  Check the proxy settings that blocks maybe, or a firewall.

  System Preferences > network > Advanced (for your current connection) > Proxies

  Something there?

• Siri does not (problems with the connection)

  Hello

  I installed macOS Sierra yesterday. Everything seems to work fine, except Siri. With Siri I always get an error message "I am having some problems with the connection. Please try again in a moment. ». But this seems to appear every time. The network connection works fine, I can't access the Internet without problem.

  No idea how solve the problem?

  I use an iMac (27 inch, mid-2011). Internal microphone is connected, I also see the 'waves' change while I am speaking.

  Concerning

  Thomas

  Hey, thochstrasser. Thank you for using communities of Apple Support.

  It seems that Siri is reluctant to make his debut on your iMac after upgrade to Mac OS Sierra. I want to make sure that you get the benefit of this new feature on a Mac.

  1 try safe mode if your Mac does not start -even if your iMac to market, safe mode makes sure it starts successfully.

  2. How to test a question in an another user account on your Mac - since this is most likely a software problem, test to another user will indicate if it is right to your user account or throughout your system.

  3. use Time Machine to back up or restore your Mac - if it seems to be systemic, the next step should not cause problems. But it is always better "to have" a backup to the "need".

  4. on OS X Recovery - the issue as part of the operating system, reinstall should do.

  Have a great weekend!

• iOS 10 problems with the Mail application

  Dear Apple and community support,

  Here's my problem:

  I have upgraded to iOS 10 on my iPhone 5s this afternoon (September 13), and now I'm not able to open e-mail - Yahoo!, and Gmail. I can receive emails, I'm not able to view the body of these emails. When I press on them, all I see is a blank white page. I can't answer emails either. I can only their flag or remove them. However, I am able to compose new e-mail messages.

  Here are the steps that I've taken to try to solve my problem:

  1. Restarted my phone
  2. Remove and re-add my Mail accounts
  3. Made a backup and a restore full while that plugged into my laptop with the latest version of iTunes.

  I should be grateful if you would help or more information on this issue.

  Thank you

  Emily

  I also have problems with the Mail application.  On my iphone, ipad, and Mac Pro.  I have several addresses, a MSN, another on Go Daddy and Gmail.  I have various weird problems with threads and every day he re-charge my emails, like if I have never read before.  Something is really problematic with Mail.

  Can the people of APPLE, you help me?

• Problem with the installation of iOS 10

  I tried to install iOS 10 earlier but it did not work, so now that I'm trying to reinstall iOS 9 if my phone will work again, if this does not work I have to reset my phone (but I am a fool and did not a back-up because I never had a problem with the software updates in the past if all data will be lost).

• Hello! Someone has some problem with the haptic on Macbook 12 "2016 function? It does not work on my Mackbook.

  I'm trying to figure if someone has my problem with the haptic on Macbook 12 "2016 function. The option is checked in the preferences system, but it does not work.

  Thank you

  Hello luigi10m,

  Thanks for posting on the Community Support from Apple. From your post, it looks like your haptic feedback does not work when you click using your trackpad and the setting is enabled. I know that this is a great feature and it is important to make it work. I'll be happy to help you.

  First of all, I would like to assure you that in system preferences > Trackpad > clicking silencer is not checked, that might help. In addition, it would be useful to reset the settings of the SCM. You can find instructions here: reset the management system (SCM) controller on your Mac - Apple Support

  I'll also include those for you here:

  1. Stop the Mac.
  2. Plug the MagSafe or USB - C adapter to a power source and to your Mac.
  3. Use the built-in keyboard, press shift-control-Option on the left side of the keyboard, then press the power button at the same time.
  4. All the keys to unlock, then press the power button to turn on your Mac

  Take care!

• I have a problem with the content of spam. Somewhere in the Fox appeared script that's choking me audio spam. Every 30 minutes he's playing an audio clip that is malicious.

  Hello.
  I have a problem with the content of spam. Somewhere in the Fox appeared script that's choking me audio spam. Every 30 minutes he's playing an audio clip that is malicious. I can't find the settings as it eliminated. Now, I don't have any plug-ins and Add-ons strange that were not initially in the Fox, but the problem is there.
  I use the Fox years. The problem, he had 1.5 months after Fox cleaning. If the problem can't win, I'll be forced to give up the browser, and I wouldn't.

  Could test you mode without failure of Firefox? It is a standard diagnostic tool to disable some advanced features of Firefox and extensions. More info: questions to troubleshoot Firefox in Safe Mode.

  Does not work if Firefox: Hold down the SHIFT key when you start Firefox.

  If Firefox is running: You can restart Firefox in Mode safe mode using either:

  • button "3-bar" menu > "?" button > restart with disabled modules
  • Help menu > restart with disabled modules

  and OK reboot.

  Two scenarios: A small dialog box should appear. Click on 'Start mode safe' (not update).

  Any improvement?

  If the problem persists in Mode without failure, could reinstall you Firefox in this way:

  Clean reinstall it

  We use this name, but it isn't about deleting your settings, this is to ensure that the program, files are clean (not incompatible, corrupt or exotic code files). As described below, this process does not disrupt your existing settings. Don't uninstall NOT Firefox, that does not need.

  (1) download a fresh Installer for Firefox 38.0.5 of https://www.mozilla.org/firefox/all/ in an ideal location. (Scroll down your preferred language).

  (2) close Firefox (if applicable).

  (3) to rename the program folder, either:

  (Windows 64-bit folder names)

  C:\Program Files (x86)\Mozilla Firefox
  

  TO

  C:\Program Files (x86)\OldFirefox
  

  (Windows 32-bit folder names)

  C:\Program Files\Mozilla Firefox
  

  TO

  C:\Program Files\OldFirefox
  

  (4) run the installer you downloaded in the #1. It should automatically connect to your existing settings.

  Any improvement?

  Note: Some plugins can only exist in this OldFirefox file. If it is missing something essential, present in these files:

  • \OldFirefox\Plugins
  • \OldFirefox\browser\plugins
