Using external triggering NI 5762, 7966R

Hello

We use the FlexRIO system to acquire and analyze data from the digitizer. To do this, we are triggering off an external source. I noticed that when you use this external trigger, the trigger for entry remains true for several clock cycles we experience an unwanted retrigger. In addition to an external trigger short pulse, what is the best way to go about this problem? We are the acquisition engine programming in LabVIEW.

Hi Jarrisonwins,

It is possible that the trigger would be high depending on the sampling frequency, you use for the trigger line. Is it possible to send a screenshot where you read the trigger line? We want to assure you that we are only to detect the edge transition and not simply looking at the logical level. Also, have you had a chance to scope of the command source? Is it possible that you actually send over a front? There should be logical debounce within the trigger line, but it may be worth looking at the incoming signal.

  • RelativeInitialX is valid for the externally triggered measures? NEITHER SMU 5122 64 MB per channel

    For example when you use the following commands

    niScope_ConfigureDigitial (with a positive delay)

    NiScope_SetAttributeViInt32 (NISCOPE_ATTR_FETCH_RELATIVE_TO to NISCOPE_VAL_READ_POINTER)

    followed by

    niScope_FetchBinary16 (loop to retrieve the data most wfmInfo)

    What will be the value of the wfmInfo.relativeInitialX before the external trigger?  It matches?  It is set to a number to indicate the outbreak did not appear until the trigger has been received and it then becomes accurate after receiving the trigger?

    I would use it to make a set FecthForever to date, but synchronized to an external trigger waveforms up to about a minute.

    It seems that the delay of release for the 5122 should be able to hande a minimum delay time of about 170 seconds (at the max rate of sampling more at lower rates), so the data I would need could all be borrowed buffers read-ahead externally triggered and properly after off-delay measurement.

    Thanks in advance for any advice.

    In the case that you are extracting data from before trigger (extraction of data before a relaxation was produced., relativeInitialX will have the same value as absoluteInitialX.)

  • How can I save my apple devices using external storage

    How can I back up all my apple devices using external storage and not iCloud and iTunes

    iDevices are designed only for backup of iCloud or your computer using iTunes. If you make regular backups of your iDevices to your computer using iTunes and back up your computer, then you will have a backup stored on the computer and your backup disk. You can also backup to the cloud for extra protection and convenience.

  • Satellite A200 use external battery

    Hi all.

    I have the Satellite A200-PSAE6E, and I bought a universal external battery. But external battery cannot produce enough current to my laptop when the internal battery is not full. When internal battery is fully charged, external keeps it full and portable computer running, but when the internal battery is not complete and I plug the external battery in seconds laptop shows that it is plugged in, charging the battery, but after a few seconds, it shows only that the laptop is plugged, and battery charge.

    Problem is that when the laptop is plugged in and the battery won't charge it uses an internal battery (as when it is not plugged in), and it drain the internal battery it turn off and there was still shows that it is connected. Can I define that when the laptop is plugged in, but does not charge to use external power?
    I'm sure it's only the software solution.

    You ad is really confusing

  • Any way to reinstall windows without using external software?

    Sometimes I use programs that are too big for my computer.  They are usually dialog boxes.  And dialog boxes usually have the final orders down.  Which I don't see.  I drag the window to the top, but it is still too long and I can't move it all further because the title bar is completely out of the screen at the top.  I'm holding it by a single line one pixel.  With the help of the tool move does nothing: it must always click/drag on the title bar.  Is anyway to move in a coordinated way, without using external software such as Sizer?  Sorry, I've had the suspect using substantive programmes and it really wouldn't help me, because I do not see the handle which allows access to the size options.

    To move the Windows Active when you can't reach the title bar with the mouse cursor, press and release of + , and press .  You can now use the cursor arrows to move the window back to the desired location.  When the box is located here where you want, press .

  • How to use external fonts in SVG?

    Hi all

    I have a bit of a struggle to understand how to use external fonts in SVG documents.

    I first tried incorporating that the fonts in the document () by JSR 226, but then it appears that this is not supported on the BB, (quite old) documentation says you can xlink to an external file and gives an example:

    I'll start by saying I have absolutely no experience but will see if I can help you and learn something too.

    I looked at the http://www.w3.org/TR/SVGMobile12/fonts.html and at the bottom it shows how to use a SVG file for the police. If you used then "javax.microedition.m2g.ExternalResourceHandler" you could load the SVG and use it to move the 'police' to the ScalableImage and get your SVG rendered (theoretically).

  • Using external microphone/headphones on Eee PC

    Is it possible to use external headphones w/microphone and headphones on an Asus Eee PC1015PX?   With a single port for mic w/either audio or headphones, the sistem does not seem to allow this thought even that support Assus said yes he can.  Do I need a special driver? It requires a full version of Windows 7?  Mac P.  Thank you.

    Hi Mac, P

    If you only have a single port, then you can use the external headset w/Mic or headphones.

    If your headphone or external headset w/Mic is a usb device then you can plug the device into a usb port.

    Thank you.

  • Can I use external links to my pictures? BC supports this feature? If so, please give me a solution for this.

    Can I use external links to my pictures? BC supports this feature? If so, please give me a solution for this.

    There is no need to make several posts on this.

    First you must understand how the web works. When you visit a website, your computer downloads the images, it's cache, it stores images, load the images and presents them. This is the basic concept.

    All Web sites can incorporate an image from another website, including BC.
    What you say does not concern if you can hotlink on BC or not... That is until you are actually doing. You mention a CSV file so that you have a web application with custom image and by the CSV field putting external URLS?

    What is an example of the url you put in? -C' maybe is incorect or in a bad way

    What is the configuration of the layout of the web application? -It can not do it in a way to manage the external URL...

    There are several things that could be wrong, then you really need to expand on things, please.

  • Use external Javascript to the PDF zoom native control

    This is my first time posting and I'm not sure if this is the right place to post.

    I have an embedded pdf I want to disable the toolbar on. The only downside is that I don't want to rely on people knowing the ways around not having the buttons. Already, I have a zoom in and zoom back button somewhere else on the page. See the Image. I would like to use external keys vs those on the pdf, it's that I'll link to images not PDF I use zoom buttons for. Is it possible to access the zoom features of native adobe through external code reader?

  • When using external schema which is always stored on the heap?

    Hi all

    If I have a regime like that...
    <distributed-scheme>
        <scheme-name>distributed-scheme</scheme-name>
        <service-name>TestDistributedService</service-name>
        <backing-map-scheme>
          <external-scheme>
            <lh-file-manager>
              <directory>/temp/odc-data</directory>
            </lh-file-manager>
          </external-scheme>
        </backing-map-scheme>
    </distributed-scheme>
    .. When I place the data in a cache which is always stored in the heap?

    When I do a test, I see that obviously the data are not on the job I can add entries massively more before I run out of memory.

    Reminder of levy of the VisualVM tool I see as many instances of com.tangosol.util.Binary I entered - so they are always keys on the job?

    If I add the index then I see that they are on the job, so I'll have the keys and the values indexed on the job. I find myself with twice as many instances of binary that I put entries, which is logical index contains a reference to the binary key.

    The reason why I ask is because I set up a "Dev version" of our application using < external-system > everywhere you would normally use a < local > schema so that we can run a version of our app Dev tests on development with low RAM machines. She needed a few tweaks and a custom DefaultConfigurableCacheFactory, but seems to work very well. Now, I'm trying to understand how much space check us and how many 'data' is always on the job.

    See you soon,.
    JK

    Hi Jonathan,.

    As can imagine you, the value is placed in the external store and the key is kept in a mapping of keys on the job. In fact, the external Bank has a binary key and a binary value. The index also works as you guessed.

    Kind regards

  • External triggering of GigE camera

    Hi, I'm planning on using the camera triggers the entry to start capturing images but I'm not sure what I need to do in my c# application when a trigger has launched.

    -If the trigger is coming from the PLC, should I also send a trigger signal to the PC and keep the active trigger signal until the PC is the acquisition of the image?

    -Do I still need use the snap or enter functions in imaqdx to get the picture?

    -If the camera is connected directly to the external NETWORK card triggering she still great benefits? The camera in less than 5 meters from the PC.

    Thank you

    Hi riscoh,

    When you work with a GigE camera you are not anything on the computer triggering its self, only the camera.  When it is configured to trigger it will sit and wait for a trigger.  When he received the signal it will take an acquisition and send the information to the computer.  When you set up your support on the computer it is searched for images and brings them into the computer as they become available.  The example I'm pointing you will show you how to set up the camera by a trigger program.  It looks like it may be available only in Visual C.  As far as the documents relate to article after the release with a GigE camera Developer area described briefly.  Acquisition of cameras GigE Vision with Vision Acquisition Software-part II
