• generation of buffer desired waveform ╔chantillonnage clock and clock frequency sample resulting

  Hello, I'm trying to generate a square wave on an ongoing basis for NI6221 DAQ to 2 kHz. I use the example of Cont Gen tension Wfm - Int Clk.vi, which works great for my needs. However, the synchronization frequency setting is sometimes different frequency resulting, according to the choice of the samples and the Cycles / buffer. Tracking dozn the origin of these variables, all come from the nodes property of the moment-DAQmx in Buffere waveform generation (multi) .vi, where the input and output frequencies are not the same. Now, why is it so? What is the way the rate is calculated? I guess it's related to an internal approximation of the Council divided by sweep sampling frequency, clock but how exactly?

  I found some notes in the help (see figure), with a few diagrams of the oscillators according to the DAQ (M type) card, but then I'm lost.

  Thank you very much

  Virgilio

  The AO sample clock is generated by dividing down the time base.  If you select a clock frequency sample that can not be achieved by dividing the time by an integer base, the sampling clock frequency will be rounded up to the available sample rate nearest (it might be interesting to note that tasks HAVE always round the frequency rather than rounding to the nearest available).

  For example, the maximum time available for AO internal base is 20 MHz.  If you select a sampling frequency of 300 kHz, this wouldn't be possible (20 MHz / 66.66666...).  Instead, ~298.5 kHz will be used (20 MHz / 67).

• Executable built with CVI 8.1 error-5093, the analysis library is not found

  Upgraded to 8.1 Labwindows/CVI of Labwindows/CVI 7.0 development machines. An earlier application was built using the ICB 7.0 and installed on a test computer. The same code built with CVI 8.1 is any error during execution of the function stdev, 5093 error code has been generated. (From analysis.h: LibraryNotFoundAnlysErr =-5093, / / the analysis library was not found.) Tried to build a facility with 8.1 and installation on the test computer and application errors still executing the stdev function. Back to the same application, but built with CVI 7.0, it works fine. Am I missing something with the build in 8.1 options? Or is it something in the workspace or project? Please notify. Thanks in advance

  Hi Tommy,.

  In CVI 8.0, the implementation of the analysis library has changed a static library that is linked to your .exe in a DLL that must be loaded when running. If you rebuild your source code and you want to deploy to another machine where the CVI environment is not installed, then you must re-create an installer in CVI 8.1 distribution, so that he can pack the analysis as well as your program library.

  You can confirm whether the analysis library is installed by searching for C:\Program NIUninstaller Instruments\Shared\Analysis\nianlys.dll in your target machine (although it is not enough to simply copy this file manually).

  When you create an installer in the CVI, be sure that, in the tab drivers & components in the dialog box change Installer , support of analysis element under the Group of LabWindows/CVI Run-Time Engine is checked.

• Sampling frequency of input/output does not match.

  Hi all

  I recently moved to audacity to audition and I have a small question: I have a Zoom h2n who worked well with Audacity, but when I tried my first recording with audition, I was told that my input and output sample rates do not match. I've already looked around and discovered that I need to change the format of my speakers to match the entrance to 44.1 I my h2n zoom fixed to however I was wondering if there was when even just ignore it. What the output is important in any case, my fault for my speakers is quality studio 24 bit 48000. Did I miss an option in the settings of the hearing? What I really need to drop out of the enclosure to 16 bit, 44100?

  Thanks in advance for any help.

  Peace.

  If you use the Zoom as an interface to audition then you really must match your session, the sampling frequency of the aufdition otherwise interface is going to be on-the-fly resampling

  So when you create a new session you assign at the same rate as the Zoom or vice versa

  You can also try to edit > Preferences > Audio hardware and check or uncheck the "attempt to force material to document sampling frequency.

• Zoom frequency in frequency analysis

  Is it possible to zoom in on a range of frequencies in the frequency analysis?  I am looking for below 200 Hz noise but would like to know more precisely what frequencies are involved.

  If you right click and hold on to the frequency bar, you can select the frequency range you want to zoom in on. Left click will allow you to go up and down the range.

  Variable cursor allows you to pass between PL/SQL stored subprograms and their clientssets of query results. This is possible because the PL/SQL and its clients share a pointer to the work area where the result set is stored.

• HP LaserJet Pro CM1410: HP LaserJet Pro CM1410 analysis but do not print

  I was printing and scanning of this printer for four years, but now my printer will scan only and don't print (Word or Notepad). I can print from an iPad. I tried the Scan doctor, but it cannot connect to the printer - a few minutes after I scanned a document from the same laptop computer on the same printer.

• Error: "the file is maybe damaged. the file header does not match the checksum calculated"during the installation of Windows 7/8

  * Original title: Question of re-Installation of operating system.

  I got the message during win 7 / Win 8 installation.

  "the file is maybe damaged. the file header does not match the checksum calculated.

  My config - processor Intel C2D, 2 GB of RAM, Intel motherboard, 500 GB HARD drive

  I have also replace Win 7 DVD and DVD player also replaced.

  I also reinstall my single RAM chip so many times. but the problem still exists.

  During Win XP SP 3 installation, no such message type not displayed. I can install it easily.

  Pls help me Sir, I would like to Win7 in my computer again.

  Hello

  Thanks for posting your query on the Microsoft Community.

  According to the description of the problem, it seems that you are facing the question with the reinstallation of Windows 7 on your computer.

  Because the computer does not recognize the CD - R into the DVD player probably boot order is set to hard drive first. I suggest to change the DVD boot priority in the BIOS and then try to perform the Startup Repair.

  Note: BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  In order to make changes in the BIOS, I suggest you to contact the manufacturer of the computer.

  Method 1:

  Unplug all external devices connected to the computer with the exception of the keyboard and mouse and check if the problem persists.

  M odes 2:

  If the problem persists try the Startup Repair. It is one of the recovery tools in the System Recovery Options menu. This set of tools is on your computer's hard disk and on the Windows installation disc. To learn more about Startup Repair , you can refer to the below mentioned article:

  http://Windows.Microsoft.com/en-us/Windows7/Startup-Repair-frequently-asked-questions

  Method 3:

  In addition, if startup repair is not enough, you can perform a system restore, check if it helps you to solve the problem. For reference, you can see the article mentioned below.

  What are the system recovery options in Windows 7?

  http://Windows.Microsoft.com/en-us/Windows7/what-are-the-system-recovery-options-in-Windows-7

  Note: when you perform the system restore to restore the computer to a previous state, programs and updates that you have installed are removed.

  Hope it would help. If problem persists always post back with the current state of your computer and the result of the proposed suggestion, we will be happy to help you.

  Kind regards

  2. Make sure your Bluetooth accessory is on and fully charged or connected to power. If it uses batteries, test them to see if they need to be replaced.
  3. Restart your Bluetooth accessory.
  4. Make sure you have the latest version of iOS on your iPhone, iPad or iPod touch.
  5. On your iOS device, go to settings > Bluetooth and make sure Bluetooth is on. If you cannot turn on Bluetooth or you see a spinning gear, restart your iPad, iPhone or iPod touch.
  6. Pairing the Bluetooth accessory, replace the accessory in detection mode, then pair and connect again.

  If you still cannot match or connect your Bluetooth accessory

  Check with the manufacturer of Bluetooth to make sure that your accessory works with your iOS device.

  Contact the Apple Support if you have any of these problems:

  • You can't turn on Bluetooth or the setting is gray.

• Of and/or submitted do not match body msg

  Hi all. Two weeks ago, I posted this problem under a different title, but got no answer, so let me try again once it is mess up maybe 5% of my email.

  Every morning I collect E-mail - from 40 to 70 messages, many from Gmail - and filtering of messages usually works effectively for transfer of the Inbox in the folders. But somewhere along the line, 1 to 3 emails get confused together: the and/or submitted do not match the text and the text sometimes includes the Source of Msg, including the text of some other, unrelated to email.

  I use FF and TB for more than 10 years now and believe this kind of email confuse goes back only a few months. I use the last Thunderbird in Windows 7 on a Dell desktop computer. I have 4 addons I hope so innocent. Of course I can send screenshots and the source of the message for analysis.

  Hoping this time to draw attention to the problem! Thank you!

• Parameters specified by step do not match the settings of the sequence

  I just upgraded from Teststand 4.1.1 to 4.2 and have encountered this

  problem during the review of the existing sequence files.

  When I open a file of sequence, select any stage of type sequence call, which calls another sous-séquence

  in a different sequence file, I learned that the parameters used do not correspond to those required.

  To be more precise, in the settings area of the stage, a red exclamation symbol appears at the side of the

  subsequence called step, and the ToolTip is displayed when the mouse pointer is

  hovered over the exclamation point States:

  "Parameters specified by the step do not match the settings of the sequence."

  The ToolTip goes on to explain how to solve this problem by clicking on the exclamation symbol.

  I find also that by deselecting the "Prototype using sequence" tab in step Settings\Module

  solves the problem.

  When the sequence is executed, no problems occur with execution, the test performs correctly.

  Is it possible to clear this error for each sequence call not in one operation?

  Thank you

  Gary.

  My apologies to attach a file of sequence buggy. I forgot to pass a parameter to the LoadPrototype method to preserve existing settings. I have attached a corrected version of the sequence file. I changed to update SequenceCall not only because of potential problems, reloading the DLL prototypes.

  I would try to explain why you see cela TestStand 4.2. The additional results feature, we added to TestStand 4.1 needs to know what parameters are entered, output and input/output (i.e. what settings is pass by reference). Before TestStand 4.1, step of calling sequence does not store this information but rather dynamically got it and it appears in the column how go. Now that we store the past by reference with the step option, you can have an inconsistency between the option stored in step and the current setting of the sequence called. This inconsistency affects only additional results and not execution. TestStand 4.1, the sequence editor to not warn you on these inconsistencies. We have added the TestStand 4.2 warning so that you will have the correct information for additional results.

  When TestStand 4.1 or 4.2 load a file of sequence from a pre-version 4.1 version, TestStand sets cervical optionally reference true for all parameters in the call sequence steps. This is why you see the warning for any sequence calling step created TestStand 3.5 If no parameters are not passing by reference. You can also see the problem if you change the option collar called a reference parameter in the sequence.

• Why do write can not be performed because the number of data channels does not match number of channels in the task.

  Possible reasons:

  Scripture cannot be performed because the number of data channels does not match number of channels in the task.

  When writing, provide data for all channels in the task. You can also change the task so that it contains the same number of channels as the written data.

  Number of job channels: 8
  Number of data channels: 1

  Lama says:

  The DAQmx vi writing gives me the error. If I run a single channel, isn't a problem. Multichannel gives me error.

  You are funny! Why tie yourself to work VI (single channel) instead of one that gives you errors (multichannel)?

  (If your car does not work, you bring car your wives to the mechanic, right!)

  What is the exact text in the multichannel 'physical channels' when you do the AO control?

  Lama says:

  I did a sequence to ensure that each function has been run in the correct order. Wouldn't a race condition.

  All you have to do is wire the 'start of task' error at the entrance of error of the DAQ assistant and then back to 'stop task' and things will run in order. Guaranteed! Think the stream! Everything else can run in parallel or the order is irrelevant.

  First convert the sequence stacked to a sequence of plate, remove the flat sequence and add the mentioned son. Now, do a "cleaning pattern.

  A when stacked with the inhabitants of the sequence is one of the worst construction you can possibly do. It makes the code difficult to follow, impossible to maintain, difficult to debug.

  Hey James,.

  I does no change, I didn't download a document from my email (from a sender of confidence). I tried to start in safe mode, just, it restarts and goes back to the corrupted checksum display... Last known good config was the same result! The only error message is one that is in the title of this post, not others.
