Acquire more than 2047 samples with the PXI-4461 instaled in SMU-1073

Hi all, I would ask you for help with the buffer limit.

I intend to buy digitizer PXI-4461 and he instal in SMU-1073 chassis, namely control via MXI Express of Labview installed on a separate computer.

What I need:

-to acquire data of a single channel of AI, but at least a sequence of 20 kS by a acquire task, in some situations until 200kS by a task to acquire.

The question:

- I can gain more than 2047 samples in a single sequence, like 200kS, with the PXI-4461 installed in SMU-1073?

Internal buffer of the PXI-4461 is reserved to 2047 samples. So I'm not sure if Labview can download remotely via MXI Express the data in the buffer of the PXI-4461 via MXI Express fast enough without any affection of the sampling program.

-in the case, this PXI-4461 with SMU-1073 isn't the right combination, what chassis and a controller can do?

Thanks much for the reply

Jan

It will work for you.

The on-board buffer 2047-sample is used only as a backup if the flow of data to the PC host (via MXI Express in this case) is not fast enough... that it will be (explained below).  DAQmx transfers data from the buffer of the device to the host PC as fast as he can and, in ideal conditions, should not save the buffer 2047 much at all.

Let's just say you get 110 MB/s (randomly from a MXI data sheet) flow on your MXI connection.  The 4461 has 2 analog inputs, which will be at 24 bits, we just round 32-bit in case it transfers the data in this way.

4 bytes/sample (32 bit) x 200,000 s/s x 2 (channels) = 1.6 MB/s, which is well below the 110 MB/s, which will make the MXI link.

clear as mud?

    Hello

    I guess 'weekend' means Saturday and Sunday, three days before the Wednesday (except weekend) would be the previous Friday.

    Change this last condition for

    AND (ROUND ((SYSDATE-aerha.last_update_date), 0)) > CASES

    WHERE TO_CHAR (SYSDATE

    , "DY".

    , ' NLS_DATE_LANGUAGE = ENGLISH '-if necessary

    ) IN ("GAME", "FRI")

    THEN 3

    5. OTHER

    END

    The code you posted is looking for a difference in 3 days.  The problem is that if you run it on a Monday, Tuesday or Wednesday, then you want a difference of 5 days (3 days + 2 weekend days).  The condition above replaces the code 3 hard with a CASE expression that returns 3 or 5 accordingly.  (If there are chances that you can run on a Saturday or a Sunday, then you may need to change the CASE expression a bit.)

    This kind of approach is not very good if you need take into account public holidays, or if you are looking for differences in N days, where N can be something of not known until run time.  For situations like this, see:

  • I can't select more than one object with the SHIFT key, selected in the last Muse app

    Someone who uses the worm. last Muse CC 2014 with Mac OS 10.10.2 and had a problem of selection of several objects by using the Shift key and hold the method has a work around. It's frustrating to try to select several objects and this simple technique does not. This same shift-SELECT approach works fine on the same calculation with other products Adobe such as PS, AI, Id etc.

    I tried your suggestion to select multiple layers but no joy and no floating above the ones I had to choose. I discuss with a representative of Adobe this morning and discovered that it is possible to select more than one by dragging on the elements with the selection arrow. This forces me to block these unwanted layers selected in this shotgun approach first. It's my best work around so far. Shift-click works in the old Muse vs7.4.30 app on the same computer. I enjoyed your suggestion and hope there is a fix for the simple approach shift-click.

  • Application errors of the RT with the PXI-4461 with Labview real-time 9.0.1, DAQmx 9.0.2

    HI -.

    I recently converted a PXI time system real OS (PXI-1042 q chassis, controller PXI-8187, DAQ, PXI-4461, DAQ, PXI-6259). I can write and run DAQmx applications in real time with the 6259 very well. Whenever I try to write a labview RT app to use the 4461, however, it will fail. Note that I can use two cards through MAX I tried switching card slots, just in case it was a problem. Both cards worked with labview, the PXI chassis was before Windows.

    Attached are pictures of the screw base demo I built to show the problem. Since I was a mistake (-200758) if I started from the raw strings, I tried to create a MAX task and use it. The task, but he complained of a buffer is too small. I explicitly put the buffer to work around this problem and still get the same error (-200608). I've also attached a screenshot of the software currently on the Max MAX RT PXI system is version 4.6.2 btw. (I installed the most/all this from DS1 Dev Suite 2010 version).

    Please let me know if I hurt something installed, versions if 4461 just don't play nice with the new BT or RT software, or if something is wrong. Thank you.

    You are allowed 2 activations as long as they are not used at the same time, so you'll be fine, you could use an external HD between the two to share the catalog and photos.

  • First elements 14 accidents system Win7 and acquires more than 8 GB of RAM when opening a project (48 clamps, 6 min on the timeline). Is there a solution?

    First elements acquires more than the 8 GB of RAM, I have in my computer, loading my project. Project contains 48 clips, the entire video has a length of about 6 min.

    It is often possible to kill ss14 and avoid a reboot of the system, but sometimes only a reboot can solve the lock.

    Sometimes the loading of the project does not exhaust the available RAM, and in these cases the continuation of the work with projects are possible without any RAM problems more (including rendering).

    Is there a solution?

    kirschnw

    What operating system is involved?

    What are the properties of these 48 clips (still images and video, just one or the other)?

    The complexity is the structure of the timeline, and what effects you apply for this clips - lots of reduction of stabilization?

    Are exhaust you the virtual as well as physical memory (RAM) in all of this?

    Please provide more details.

    I completely agree with two of your statements, I tabled a report of corrective measures that you can monitor in the next versions of DCPower to see if this is fixed with the FPS. CAR number: 512257

  • Pulse modulated CW with the PXI-5650 and PXI-6653

    Hello

    I'm trying to generate a signal CW of pulse modulated with the PXI-5650 as source RF and the PXI-6653 as the modulation signal. Basically, I'm trying to generate a simple radar waveform. It seems that it would be possible to use the synchronization Module (6653) to transform the RF output on / off on the signal generator (5650), but I do not know how to route the signals from one to another using LabView.

    Has anyone tried this or something like this before? Can anyone please offer some advice?

    Thank you!

    -John

    Hi John,.

    Reading your post, it seems you want to use your calendar and map of synchronization to the RF output power, in other words, on Off Keying. OOK modulation is a feature built into the 5650. For more information, you can navigate through the NI RF Signal generators Help for devices-RF signal generators > NOR -> NOR 5650/5651/5652 overview-> Modes of Modulation and simply click on the Modulation Modes.

    An example of this is found in the example Finder OR by navigating to the help-> find the examples in LabVIEW and then navigate in the Finder to example NOR material input and output-> Modular Instruments-> NI - RFSG-> signals-> RFSG 565 x Digital Modulation.vi.

  • I have to remove the duplicate files, but having problems by selecting more than one file in the player at the time.

    I have to remove the duplicate files, but having problems by selecting more than one file in the player at the time. How can I select multiple files at the same time so I can just delete them. I used to be able to do this in previous versions of Media Player, but this function seems now blocked or unavailable. The problem is this: through previous use of media player, it plays all my multimedia files several times whenever a device support has been added. He would try to save the files on my main drive, but since there is not enough room this would save the files somewhere else. This happened several times, I suppose, because when I upgraded my computer and a media scan was conducted he found duplicates of all my media various times of at least 6-8. I've consolidated since my plates on 3-disc multi to, but have now records duplicated hundreds and thousands of duplicate media files. Previous versions of Media Player would allow me to select all files and then delete them both of the reader, but also from my hard drive. So now I'm stuck with more than 300 GB of duplicate media I have to search line by line through all my hard drives to find each duplicate both, unless I can get media player to do what it can. Any help in this area would be appreciated.

    Hello

    1. did you of recent changes on the computer?

    2. is Windows media player files in double creation during playback of music files?

    To delete duplicate entries, click on another feature tab in the drive (for example the current playback), and then click library.

    If this does not remove duplicates from your library, you can use the Add to library dialog box to search computer to analyze a file on your computer the duplicate entries not valid-pointing. The player will remove invalid entries in your library that point to files that no longer exist in the folder.

    Complete the steps above for files that are stored in the hard disks.

    Method 1: Use the add to Library dialog box search for computers

    (a) start Windows Media Player.

    (b) press F3 on your keyboard to open Add to the library of the find computers dialog box.

    (c) click the Browse button to locate the folder on your computer so that your library contains invalid entries. Specify the location of the folder in the box look in.

    If you are not sure what duplicate in your library entry is not valid, you can add a path column to display in your library. Specify the folder on your computer that corresponds to the path not valid file displayed in your library.

    (d) click on the Search button.

    The player will search for digital media files and playlists in the folder that you specify and remove invalid entries in your library that point to files that no longer exist in the folder. If not valid in double entries point to other folders on your computer, repeat this procedure, specify a different folder every time.

    If only a small number of duplicate entries exist, you can delete those invalid manually by right-clicking on the invalid entry, and then clicking Delete .

    For large double-number of entries in your library (or if all your library is duplicated), it might be better to create a new library and delete the files.

    Method 2:

    After you remove the duplicate entries, run the troubleshooting of Windows Media Library settings to solve this problem.

    Open the troubleshooter in Windows Media Library

    http://Windows.Microsoft.com/en-us/Windows7/open-the-Windows-Media-Player-library-Troubleshooter

    Let us know the results.

    I hope this helps.

    It seems that you can only use one address for this widget.

    To do this you will need create map in Google Maps with all your points, and then copy the Google embed .html into Muse.
