Difficult to use the outputs analog to generate a predetermined file

Hey all,.

I tried to produce a file predetermined to a 1 kHz on my USB 6343 Multifunction DAQ analog output channel.

Here are the questions I have am experiencing:

1: output file so fast my o'scope cannot even pick it up.

2: when you try to stop the output it almost freezes.

3: my graphical waveform data and the plot does not update with the data that have been read.

If someone wants to tackle one or more of these questions, I would be very appreciatve.

Thank you

I tried to adjust the "DAQmx Configure Ouput buffer" but it really doesn't seem to have much effect. Do you think I should try a loop For to pick an amount predetermined points then output them quickly?

It's weird.  So I don't generally need to use the function of output buffer configuration you have.  If you look at using the Subvi DAQmx Timing just after it, you will see the samples per channel will help determine the size of the buffer.  You might want to try do not use the function of buffer output set at all, not that I don't know if that will fix it or not.

  • Using the output with 6009 or 6216 possible buffer?

    Hello

    I have a USB6009 and a USB6216. I need to generate a signal by using the analog output and I would use the output buffer. My questions are:

    -The USB6009 has an output buffer? I always get an error, but I know from experience that this device is very limited, so I wonder if they have not only an output buffer... (Programs in input buffer are not a problem at all).

    -J' took the USB6216 and I tried the example WfmGenUp.c downloaded from somewhere in the area of the developer (sorry I lost the link but fix the code) but I am not all analog output signals and after you press ENTER to stop the program (depending on the show) I get this error message:

    NO MORTALS RUN - TIME ERROR: 'WfmGenUp.c', line 113, col 9, id thread 0x0000088C: DAQmxStopTask function: (is-200016 return value [0xfffcf2b0]). Measurements: On-board memory precision passing. Due to the limitations of system and/or the bandwidth of the bus, the driver could not write data to the device fast enough to track the rate of output of the device.  Reduce your sampling rate, change the method of transfer of data (from interruptions on DMA), use a product with more on-board memory or reduce the number of programs that your computer runs simultaneously. Task name: _unnamedTask<0> Code of State:-200016

    I don't know if the problem is just that the 6216 does not support the output buffering or the other...

    -So, if the output control is not supported by 6009 or 6216 what would be the best way to constantly generate signals to 100 s/s?

    Thank you very much

    Hi Ryan,

    the USB-6009 case has 150 s/s softwaretimed AO, so you won´t be able to use AO stamped with the module.

    The USB-6216 supported in the analog output buffer, just follow the recommendations that the driver gives you,

    for example by reducing the sampling frequency, if there is an overflow memory due to the limitations of system and/or the bandwidth of the bus.

    Experiment with the parameters and the basic to see in what range of sampling it works.

    You can find appropriate examples

    Hello

    I want to configure my USB-6221 Panel in the next mode

    If I connect the trigger for a PFI (e.g. PFI5) I get the error: some resources used Cnt0 (I see no reason why by ok).

    I tried for awhile to do in a different way (I completely mixed my vi) but I did not.

    If anyone has any suggestions please shear them.

    Thank you

    Ignore my previous post.

    A mistake is this sample clock: finished sample doesn't seem to work with shutter release in this configuration.

    In any case, I found a way to get around and reach my final goal (the object) with a bath other counters and configuration of digital input.

  • What is the best way to run two concurrent programs using the output of either executing the other?

    I wanted to just kind of get a notice of some people here. I have two main screws the first is a data acquisition system that displays 99 different sensors and which feeds on these data in a table. The second is a real-time processing system that is designed to take the painting and do many calculations. The two output data from screw at the front that I want to see, so I don't want to use just as a Subvi.

    Is there a simple way to run two screws, using the output of the data acquisition system to power the processor so that you can easily see the signs before two screws? I had thought to simply copy the code from the processor in real-time in the DAQ VI, but I fear that the VI resulting will be very large and unsightly.

    On a side note, I'm more thinking about this? I apologize if this is a stupid question, it has been a long week... aaaand it's Wednesday.

    Look at the Architecture of producer/consumer.  It will be a good starting point, even if you find that you need to change.  When performing data acquisition and processing of tasks in parallel loops, they can both run simultaneously.  Both can feed data to the main draw of the VI.

    I'd probably use three loops with the third being the user interface only.  All that must be displayed to the user is sent to the GUI of the acquisition of data or processing loop loops and commands or entered by users are returned in these loops, probably through queues.  The wall of the VI of data acquisition and processing VI are never displayed to the user.  Especially the treatment, because it runs on a system in real-time, should avoid synchronization issues that can present a graphical interface.

    Deleted file recovery can recover incomplete files, i.e. the part of these files may be missing.  Recover deleted files is much more reliable if recovery of a backup, instead of using recovery software.

    These things depend on the operating system and the file system.

    One thing, you can see: open one of these files damaged with a text editor, and then make sure that the constant % PDF is somewhere in the first 1024 bytes.

  • Why using the typewriter in acrobat 9 adds less file size that the use of the text of the comment in acrobat 11 tool?

    Why using the typewriter in acrobat 9 adds less file size that the use of the text of the comment in acrobat 11 tool?

    Two employees, one using acrobat 9 and the other uses acrobat 11. The two employees open a secure document one page 105 KB in size. Used using acrobat 9 using the typewriter tool to add comments. Document increases in volume to 137 kb. Second employee using acrobat 11 uses the comment add the text tool (since it is no longer a typewriter tool). This employee has to use tool once and the document immediately increases size of 105 k to 950 + kb. Why is this? What can be done to avoid this?

    As I suspected much earlier, the difference is in the fonts that are used for the text. For the smaller file, text annotation font is Times Roman. that is a policy that is essentially built into Acrobat/Reader. For the larger file, the font is Tahoma, which is not an integrated police force, which ends by happens so the entire police gets embedded in the PDF file. The size of this font on disk file is 681KO on my system (Mac), and it ends up taking more space when they are embedded in the PDF file. The same type of thing happens with form fields and this is done so that all characters in the font are available when the text is changed in a system that may not have the installed font.

    One of the problems is if you try to reduce the size of the file by changing the font that used up one of the built-in ones (Courier, Helvetica, TImes Roman), Acrobat does not remove the now unused of the file font information, if you do not get the reduction in file size that you can imagine, even if the font is no longer presented as being incorporated. I submitted this as a bug some time ago, but it has not been fixed.

  • What are the settings use the output to "create a PDF for review?

    Product: RoboHelp 11 (TCS-5)

    Location of menu: Review > create PDF of control

    Question: The default output based on output that is unusable menu location: for example, styles are not mapping correctly, making the document difficult to read and review. Is there a default print layout or other control?

    Final objectives: Track changes, perform shared reviews, import comments of the generated PDF and so on.

    Secondary issues: Can I import the comments/markup of a shared review if I generated PDF file by using the page, instead of the magazine > create PDF for review menu option? If so, I will then be able to manage comments in the reviewing pane and perform other functions related-review?

    In my view, it is mapped via CSS. I don't think you can change this behavior.

    If you generate printed material, it is NOT possible to import review comments.

  • Cannot use the output of javascript function in the scriptlet

    Hi I am using the listboxes in a jsp page. There are 2 drop-down lists.
    Once I click on a particular value in listbox1, the listbox2 is filled according to value in listbox1.

    which means I want to use the value in the list box as parameter 1 to fill the listbox2.

    Note: the values to listbox1 are filled with the values from the table to the oracle database.

    Here is the code I tried to frame.

    I have a listbox with the following code 1

    < select size = "5" cols = "30" name = "view_label" onclick = "testSelect (this.form)" > "

    < SCRIPT >
    function testSelect (form)
    {
    var multipleVar = form.view_label.options [form.view_label.selectedIndex] .value
    If (form.comments.value == "")
    {
    Form.comments.Value = multipleVar + "\n";
    }
    ElseIf (form.comments.value! = "")
    {
    var insertedMultipleVar = form.comments.value;
    Form.comments.Value = insertedMultipleVar + multipleVar + '\n '.
    Form.comments.Value = multipleVar
    }

    }

    < /script >


    It's listbox 2 which is based on option 1 OnClick of the listbox

    < select size = "5" cols = "30" name = "applications" >

    < %
    ResultSet rsetlovp = lovbean.getAllQueries (/ * Function testSelect output * /);
    While (rsetlovp.next ())
    {
    out.println ("< option value =" + rsetlovp.getString ("query_position") + ">" +)
    rsetlovp.getString("query_position") + ' < / option > ");
    } % >
    < / select >


    How can I switch the output of javascript function to getAllQueries() method?

    Please can someone help on this...?

    It's really a bit difficult to answer your question without a little more information. What version of JDeveloper are you using? What is your technology environment?

    In the case of JDeveloper 11 g + +, with the Fusion technology stack, you can use a technique similar to that described here:
    http://Groundside.com/blog/GrantRonald.php?title=jdeveloper_11_business_services_cascadin&more=1&c=1&TB=1&pb=1

    JDeveloper 10.1.3 with the default Web technology stack, check here:
    http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html#62

    If, as looks, it is really a question about generic (no JSF) JSPs, you could actually have a little more success on a generic JSP forum - using scriptlets was not really practical copies within JDev since... Well, since JSTL became available, really. It was a number of years.

    As I said, there is really no direct way to use Javascript in a scriptlet - unless you mean something like store the output of Javascript in a hidden field and using the value in a scriptlet on the next request. But at the point where Javascript executes, a scriptlet for the current request will be already performed.

  • Integrate the outputs analog with analog inputs

    I have a program that displays 2 analog output waves and a separate program that captures the analog data through several materials of NEITHER. I need to integrate the program outputs analog in my analog input program.

    The program of analog output is fixed as "AO_Triggers_LowLevel.vi" and the analog input is fixed as "ExperimentDAQ.vi". When I try and integrate these programs I get 'error-200560 occurred at DAQmx waiting until the Done.vi' to my function to wait until it makes my task of analog input (background of the program). I think it is my mistake in the order that I'm wiring to the top of my son of error but I'm not sure. I watched several tutorials (Timing and synchronization features of DAQmx) but I'm totally stuck.

    Any suggestions are greatly appreciated. Thank you!

    I think I've fixed this problem. I extended my flat sequence structure to include the lines of task and error of my task outputs analog and things seem to work.  I'm still not sure about what caused my error and why it has solved the problem...

  • I have a HF G40. Can I use the outputs on this camera livestream?

    With my old camera i I could use the video output on it to connect to my laptop which is connected via fiber on the web. I used xsplit braodcaster as the software & just livestream via youtube. Is this possible with this device? There is a port mini hdmi & a video output on it. These can be used? There is also a micro usb port. I tried the usb port, but my computer does not recognize it. Has anyone tried this before? I love the photo, but my main use is livestreaming sports & need a device that can do it.

    Hi CoachLoll35,

    Thank you for posting.

    Live broadcast is not available via the USB port on your camcorder.  While the HDMI streaming is not a supported feature, if you have a computer with a HDMI capture device, you can stream from this terminal.
