At the same time Record several channels in DAQ

I'm currently configured to play two channels in data acquisition using DAQ Assistant. I wonder what would be the best way to go on the sampling of these channels at the same time, or as close as possible. The vi that I currently use is attached.

Thank you

Sawyer

DAQmx manages the calendar under the hood and does it quite well.  If you want to change advanced sync settings you can, but of course, you will have to abandon the DAQ ASSistant and write a LabVIEW code.

I assume you are using a multiplexing card right?  The only real solution for true simultaneous sampling is to buy a card that has several a/d converters like the S series cards.

For the second poster: you do not have the same problem as the op.  It can be implemented in multiple channels.  If you want to help, you must provide further information that "it gives an error.

EDIT: I bet you are trying to use separate tasks for each entry, aren't you.  If you do, you'll get a resource conflict error.  You must use a SINGLE task and set up several channels in this task to collect more than one signal.

  • Update of Smartphones from blackBerry to OS 4.5 for updating at the same time to several Blackberrys.

    I was wondering if there was a way to update multiple BlackBerry operating system at the same time? or is there a different software that can do?

    Yes, you can update several at once, according to the number of USB powered ports on your PC.

    So, if you have two of the rear USB ports, you can update both at the same time, using the "loader.exe". Do not use some 08/04/16 ports USB hub, just the main PC usb ports.

    1. download the OS files to the PC then install on the PC by running (double click) the downloaded file.
    2. go in c:\program files Research in motion\apploader and delete the file named "vendor.xml."
    3. plug in the BB and double-click on "Loader.exe." It is located in the same place as the above vendor.xml file.

  • ISight does not record in imovie7.1.4, while at the same time recording with garageband

    MBP 2.2 GHz Intel Core 2 duo on OS10.6.8

    I have taken steps (Please read if offering suggestions).

    Here's what I did successfully for years, and now it does not work.

    While recording video directly from isight in imovie 7.1.4, I'm simultaneously garageband (4.1.2, aka GB ' 08) running and audio recording.

    When I hit 'stop' in I saw, she would generate thumbnails, I hit 'done' the isight would disappear and complete video went directly into the imovie editing area.

    Please note that I have tried the following procedures at least 3 times or more there where problems are reproducible.

    What is happening now is that isight does not generate thumbnails either and when I hit, I get the ball spinning eternal, does not close the window of the isight, & I have to force quit.would

    I tried to close GB before hitting the stop on the isight - same problem camera

    Sometimes he would record only a small part, and once I opened GB, this offer would get no audio recorded.

    Another thing that is strange is that with Go out completely, isight, would be to save and build all thumbnails with success. As soon as I opened the GB, the video would have this effect of idle power not obvious then only imovie was on.

    Here's what I've tried so far:

    1. I disconnected and connected to another account, and it worked. The video followed well, recorded in its entirety, generted all thumbnails in the Edit with GB check box.

    Here is what does not work

    2.i went back to my main account. I copied all preference files in the library, placed in another folder on the desktop, then deleted all files in preferences in the preference folder in the library. Then, I rebooted the computer - same problem.

    3. I copied all the preferences of the library in the account of the other, deleted all preferences of the main account and placed alternative account preferences, rebooted - same problem.

    4. I then put the original preferences, done a permissions repair, zap PRAM, etc... . same problem

    5. I tried to simply remove the nd imovie7plist in the folder preferences folders to host BY - same problem

    6. I tried to open another GB file from scratch - same problem

    I would like to know if there is a way I can just imovie to uninstall, and then reinstall without touching GB or Logic 9 that I installed. I don't know if the relocation means the package whole ilife by default because I also have logic 9 in which files are shared by GB, and it might spoil some shared folders, etc. ..

  • I have a DAQ Assistant configured to read several channels at the same time. When I have a graphical indicator of wire to the output, I see all my signals mixed together. How I divided them into separate signals?

    I have a DAQ Assistant configured to read 2 channels at the same time. When I have a graphical indicator of wire to the output, I see 2 signals mixed together. How I divided them into separate signals?

    When I wire any type of indicator, it is show that a release of a single channel.

    I want 2 indicators showing 2 different signals as expected from 2 channels configured. How to do this?

    I tried to use split signal but it end by showing that 1 out of 1 signal two indicators.

    Thanks in advance.

    Yes you are right. I tried, but I don't have the result.

    I just find the path. When we launch the split signal, we should expand it (split signal icon) by top, not the bottom. It took me a while to understand this.

    Thank you

  • Why can I no longer apply ratings to several photos at the same time?

    I used to be able to select several images and their add the same note at the same time. Now a single image will have the side has changed. Why?

    Opening 3.6, El Capitan

    Disable the single primary indicator.

    See this: keywords or ratings are only applied to one of the selected images - why?

    The reason is usually that the "Primary" indicator only is defined. With this option enabled, the changes by using the keywords, notes and other metadata will be applied to the only "primary selection": the primary selection is the active image selected. This image is marked by a thick white border in the browser and Viewer, see paragraph "navigating through and selection of Images" in the Manual of Aperture 3.

    To enable or disable the "Primary" indicator only, toggle the button "Primary only" marked by a '1' in the display controls, or use the main menu to open bar:

    Edit > primary only.

  • Highlight one several files at the same time

    I would like to highlight several files to delete at the same time. Through Windows highlight you or click on the first file with the mouse and click on the last file and everything in-between becomes highlighted for deletion. Is there a way to do the same thing with my Mac without clicking on each file individually?

    OS X does not have an iota of code Microsoft Windows. Do not expect that it works in the same way.

    1. You have the choice on OS X. You can click and drag the file icons that you want to remove, then right-click on one of them and select move to trash.
    2. You can select the first icon in the file and then pressing the SHIFT key or order, select the following icons. Then click on any place in the trash.
    3. Step 2, but using the arrow keys for the selection of additional directional file icon.
    4. Combine [1, 2, 3] to add or subtract icons from file.

  • Can I use USRP 2 channels at the same time to receive a signal?

    Hello world

    I want to do an implementation of the time difference of arrival between two receivers (antenna) estimate. I have a kit USRP, Remora and two antennas. There is only one signal source (it is transmitted in nowhere is not serious).

    Can I use two channels at the same time the USRP to receive a signal?

    I need the original source signal and the delayed signal version.

    Thanks a lot for your help.

    Sincerely yours.

    Uysal.

    Hello

    I found this post on the forum that can be useful for you.  Looks like you can not receive two antennas in the way you describe.  I think that this would require a configuration USRP two.

  • NEITHER 9207 reading current and voltage at the same time channels

    I have a cDAQ-9178 chassis USB-three cards NI 9217 RTD, three cards 9263 0 - 10V and one the output OR 9207 16 channels analog card. What I m trying with this kind of things, is to read all the analog input channels (information of transducer, temperature, pressure, etc.) and adjust my controls to process with the analog output channels.

    My problem at the moment is the following:

    When I create tasks with DAQmx VI:s, how to create a task that reads current and voltage on the 9207 channels at the same time?

    When I created a task for RTD-channels (16), a task for the outputs analog 0 - 10V (12), a task for the analog input 4-20mA (8) and a single task analog 0 - 10V input (8) I get an error-50103. I think it s because the tasks of current entry and voltagge are trying to use the same CAD at the same time and LabVIEW informs that "The specified resource is reserved. Tasks are to leave so that the analog output task starts first, then I merged all clusters of the error and the rest of the task are started by an order to current input-> input-> RTD input voltage. I get this error after the current enter task started and enter voltage task begins.

    Because I m new on the LabVIEW and stuck in that time, I wanted to try the forum to find answers. I tried to find if someone else was having the same kind of problem, but with a quick search, there was none. I m in a bit of hurry, so I apologize if West a subject with a happy for that and I missed too much according to me.

    Really, the best way to do it is just adding 8 channels of voltage at a task, then 8-channel current, somewhat like this:

    Then spread over different channels when you read later:

    It should run without error.  It always is multiplexed to sampling, but it will be much faster to create two separate tasks.  There will be between 2ms (mode high speed) and 52ms (mode high resolution) between each playback channels, but it will still be much faster than the permutation of the tasks.
