How to Acquire Data at High Rate for Several Seconds?

Hello Everybody,
I am using a PCI 5152 with 64Megs of memory per channel. I am also using Labview 7.1 in WinXP. My PC is a Quad Processor Computer with  2GB of Ram.
I need to acquire data for several seconds as follows: I am triggering at 1ms and for each trigger I want to save the first 200us  of data at the highest possible rate (more than 200MHz).
I have developed the code attached but I keep getting the error -1074116198 (buffer overwrite).  Any ideas or suggestions are welcome
Thank you very much  in advance.
Jhon.

Hi Jhon,
Could you please provide a screenshot of the front panel for your VI when you run the program and receive the error (I want to know what each value is set to). Are you able to run the program without error when you decrease the record length and/or sample rate? Additionally, what are the values of the Records Fetched and Records Acquired indicators when you receive the error? Can you please provide a screenshot of the actual error message you are receiving as well? Finally, I am curious to know why you are taking your min record length value and dividing it by the period (reciprocal of min sample rate)? I look forward to hearing back from you soon and reproducing the issue you are seeing.
Cheers!

  • How to acquire data from the memory of multimeter

    I am a beginner of Labview. I don't know how to acquire data from the memory of multimeter.
    I read some examples about DAQ, but it seems not similar to my case. I can't use DAQ in my computer, as I don't have DAQ board.
    Could anybody give me some guide? Similar examples would be great.
    Solved!
    Go to Solution.

    Confirm that you have the VISA Run Time Engine on the target machine. If you do not have it installed, you can install the VISA Run Time Engine from ni.com.

  • How to set a new SCSI number for a second drive?

    How to set a new SCSI number for a second drive?
    Walter

    Walter,
    This web site gives a good diagram:
    http://www.hitachigst.com/hdd/support/dpes/dpesjum.htm
    On a Quantum hard disk drive - they were the original equipment manufacturer (OEM) hard drive provider for Apple, you will see three or four pairs of pins on the green circuit board. They are labled:
    AO . .
    A1 . .
    A2 . .
    If no pins are connected, you have SCSI ID Zero This was the standard setting from the factory.
    If you short out the pins beside AO .__. , you have designated SCSI ID One.
    If you short out the pins beside A1 .__. , you have designated SCSI ID Two.
    If you short out the pins beside A2 .__. , you have designated SCSI ID Four.
    These values can be added together to get other SCSI IDs. If you have a jumper beside AO AND A1, that will add up to SCSI ID Three.
    Some of the quantum drives used tiny black plastic jumpers with tiny metal contacts. I have yet to find a store that sells the tiny ones. I get my larger jumpers from old PC motherboards that are being thrown away. A small piece of aluminum foil will work as a jumper in a pinch. Just make sure it soed not fall off and short something else out!
    Jim
    PS
    CD-ROM drives are set at the factory as ID 3. Internal drives are set at ID 0. I set my external SCSI drive at SCSI 1 so it does not conflict with the internal drive. Internal Zip drives are set at ID 5 and external Zip drives let you choose between 5 and 6. I set my burners at ID 4. Come up with a master plan for your devices like scanners and burners. Apple System Profiler will give you info on the device ID. If the computer fails to boot, turn off all but one SCSI device and make sure of its ID. Then check each subsequent device by powering up only one device at a time while booting from a CD at ID #3.

  • How do i freeze a frame in a movie and hold it for several seconds?

    Hi
    I have a clip where someone turns round and gives the 'thumbs up' to the camera - how do i hold this thumbs up position, for several seconds?
    Do i need to export a frame and import it back to the timeline or what?
    thanks

    Cut the clip in the timeline at the point where you want the "Thumbs Up" to freeze and make sure the playhead is on that frame.
    Then select Modify>Make Freeze Frame.
    The freeze-frame will appear in the Viewer.
    Click on it and drag it down to the timeline.
    You will have to alter its length according to what you want.

  • LVRT PXI Target ethernet stops for several seconds

    Hello,
    I am experiencing a problem described in this thread:
    http://forums.ni.com/ni/board/message?board.id=170&message.id=101488&requireLogin=False
    A brief explanation is: during TCP transfers, the data transmission will pause periodically, for several seconds.  In that case, LV version is 7.1, and the solution was a maintenance upgrade to 7.1.1.  In my case, the LV version is 7.0 (I am supporting a customer application), and because LV 7.1 was not purchased, the upgrade is not available to me.
    Is there a similar fix available for LV RT 7.0?  OS is Windows 2000.
    Thank you,
    RonC

    Hello RonC,
    From what I understand, you are asking for a maintance release to improve the TCP communication.  Unfortunately, that does require the upgrade to at least 7.1.1.  One other option that might help improve performance is to set your system to half-duplex.  I have included the instructions below:
    When using a crossover cable to communicate between an RT controller and a windows host, it is important to ensure that the systems correctly negotiate signals. By manually setting these connections, you ensure correct communication with the RT system and host.
    Configure the settings in Windows 2000 or Windows XP
    Right-click on My Computer on the Desktop and choose Properties.
    Select the Hardware tab and click Device Manager.
    Expand Network Adapters.
    Right-click on the ethernet communication device (i.e. Intel(R) PRO/100VE Desktop Adapter) and choose Properties.
    Select the Advanced tab and browse the list on the right hand side. One of the items will allow you to configure the communication settings by selecting an item from the Value drop down menu. In the Value drop-down box, you will see the following options:
    100Mbps/Full Duplex
    100Mbps/Half Duplex
    10Mbps/Full Duplex
    10Mbps/Half Duplex
    Auto Detect
    Select one of the Half Duplex modes and select OK
    The host system is now set up for half-duplex communication
    Configure the settings on the RT Controller
    Open Measurement and Automation Explorer (MAX)
    Expand Remote Systems and select your Real-Time target
    Select the Advanced Ethernet Settings Button to bring up the property page
    In the property page select half duplex and select OK
    The Real-Time controller is now setup to use half-duplex communication.
    I hope this helps!

  • Mac Pro shows beach ball and pauses for several seconds

    I have an issue with my new Mac Pro (2013) wherein I can be running nothing but Pages for instance (does same with other non-graphic intense programs as well) and I will get a beach ball, then the computer will halt for several seconds until the beachball clears.  Why is this happening?  I have 500 GB SSD and 16 GB Apple memory.   This happens also when bouncing a two or three instrument song in Logic Pro.  Anyone know of issues?

    When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.

  • System freezes for several seconds every minute or so?

    Recently, within the past week, my OS has began freezing for several seconds every 40 seconds or so. I had not downloaded any applications around the time this began. The last app I downloaded was iMovie 6 (for the editing features), I downloaded this several days after this problem began. The last app I downloaded BEFORE the problem began was UnRarX, which I downloaded back in April. I have no idea how to check my specs, and computer info, please tell me how to get this and I will tell you.

    Call AppleCare. Whenever you buy a new Mac, discs are always supplied with them. Usually they come in a white envelope that is square with the user manual in the box. If you bought it from a non-Apple source, you should call them and ask them to send you the disc. It isn't their's to keep, and they can call AppleCare to order them. And no, it isn't in the Utilities folder. It is a physical optical disc that looks like a music CD, but says MacBook Pro on it.

  • Firefox will not launch. The screen goes black for several seconds, then returns to the launcher drawer.

    Installed Fennec 4.0b2 on my Acer Liquid running Android 2.2. When I tried to launch application, the screen goes to black, with a grey bar at the top with the word "firefox" within. This screen persists for several seconds, before the returning to the previous screen.

    Thanks for the report. This is a known bug that only affects Acer Liquid phones. We're working on it, but we don't have a fix ready yet. For details, see https://bugzilla.mozilla.org/show_bug.cgi?id=606194

  • My sons iPod touch stopped working, it won't charge in a docking station and the computer/itunes won't recognize it when connected.  We have tried holding the power and home button at the same time for several seconds, and the screen still stays black

    My sons iPod touch stopped working, it won't charge in a docking station and the computer/itunes won't recognize it when connected.  We have tried holding the power and home button at the same time for several seconds, and the screen still stays black.  Thanks!

    Hello skdog I possibly think your ipod touch is black because it has not charged. If your dock is broken it might just mean the dock will be broken and so might be the USB port. You should see an Apple shop nearby and hand it over and see what they can do. I hope this information works!

  • Picture is going out for several seconds. Audio continues.​..

    We keep losing picture on pretty much all channels.  It disappears for several seconds (black screen) but the audio continues.  The time it is gone is increasing as well as the frequency.  It's not the TV, because it is recorded on the DVR like this, if you rewind etc.  Any ideas?
    Thanks

    I have also experienced this I know its not the tv because it did it on my old set and now my new one.

  • HT2622 mac mini displays gray screen and says to restart computer by holding down restart button for several seconds.  Will not boot.

    My mac mini will not display home screen. When I turn it on and try to reboot it, there is a gray sceen that is displayed and then a message to restart by holding the power button for several seconds. This shuts down the computer, but then the above problem repeats.

    If the message you're getting is in several languages, that's a kernel panic. Kernel panics are usually, but not always, caused by hardware, with memory a leading cause. If you have a mid-2010 mini, you can easily reseat the memory (remove and reinstall) .... mini's prior to that are a bit more involved to open the case.
    See this FAQ on resolving kernel panics.

  • Skype maxes a cpu core periodically for several seconds and does not respond

    Skype 7.7.85.103 uses a lot of cpu periodically, and is not reacting for several seconds.
    I am not sure, if this is related to advertisements changing in these intervals, but if it is, then this should not be happening.
    I already did a clean install (inclusive removing EVERYTHING from the registry), and it did not help.
    I tried as administrator - once again, it did not help.
    It is less visible when I am connected to a powersource, as the cpu is then going faster, but it still happens.
    And it is not the first version that has had this problem.
    In case it may help, there is the dxdiag.txt attatched.
