How to set an interval of time of acquisition with DAQmx

I use a 6123 DAQ to acquire and store a voltage signal. I'm trying to figure out how I can reduce the time interval of the data acquired, rather than save 2 ms of data I want to only save the first data 100us. Is this possible?

Kind regards

Lowksi

How you configure your task?  I can assume that you are using samples for your type of acquisition.  So what you do is the VI of Timing DAQmx place your sample rate and the number of samples to be taken.  The number of samples you want will be the sampe (samples per second) rate multiplied by the interval desired (seconds).

So let's say that you buy at 500kHz and you want data 100us.  You must set the number of samples to read 500e3 * 100e-6 = 50 samples

    Hello

    I'm trying to follow the steps described in the following link:

    How to set the Date and time on a remote target in Measurement & Automation Explorer (MAX)?

    It is said

    The software on the target currently supports only the time zoneand deletes the old files?

    I need set the date and time

    and remove all the old unwanted files

    the calendar was gray does not allow me to change the current date.

    Anyone know how to change

    Hi all!

    According to this the below Knowledge Base article, Remote Configuration System Support must be installed on the target for time settings to change in MAX.

    http://digital.NI.com/public.nsf/allkb/FAB0EC4D6E5EE0F386257738005733A3?OpenDocument&MeTC=max_MAXDat...

    If you don't know what version of the system supported remote Configuration software that you have installed on your device target, it is likely that it is not yet installed. Add this software by clicking below your target to the MAX software option and selecting "Add/Remove Software". This is where you will install the System Configuration Remote Support software.

  • How to set the default value of the attribute with a sequence number? Is it possible to add a string to seq.no. like abc0001?

    Mr President.

    How to set the default value of the attribute with a sequence number? Is it possible to add a string to seq.no. like abc0001?

    Concerning

    For the date, you can use groovy expression adf.currentDate to set the current date. reference http://adfgouravtkiet.blogspot.in/2012/11/how-to-set-default-values-for-entity.html

    You already have ways to use the sequence.

    How do you add a new value in the form. You're creating a new line of your page (user interface) and by engaging with validation operation? Unless you commit you will not be able to see anything in the table.

  • time of release with daqmx

    Hello

    How can I set the time of liberation with DAQmx?

    In general, with a single DAQ hardware, the two signals are connected at the same time and the acquisition time is a function of the sampling frequency and number of samples read. For example, with a sampling rate of 1000 samples/s and 50 samples, the acquisition will be 50 msec. You then get a returned array if you wanted to watch a single signal by iteration of the while loop, it is simply a matter of indexing the specific channel to the table. You must set the mode of continuous sampling to avoid gaps and precise timing. Using two separate tasks and switching back and forth would add a lot of overhead to close/create tasks and you have little control over this period.

  • How to set the interval of validation after n lines when generating insert statements?

    Hello

    I'm trying to script sql insert with a few lines of million using SQL Developer 1.5.4.

    I can generate scripts insert ok, but can not see anywhere to set the interval of validation.

    In the form of preferences in respect of migration, I see that you can set the interval of validation under data move options, but I guess that's something different.

    I know we could use sql loader, but this insert is part of the deployment package that has a series of sql scripts that we run together. So I don't want to run a series of sql scripts, and then run sql loader and then go back to sql scripts.

    Am I missing something, or is it simply not possible with SQL Developer?

    Thanks in advance for your help,

    Pete

    Assuming that you create the insert using the export as Insert feature script, so no way to to do.

    However, once you have generated the SQL to insert script, it is quite easy to add a line at the top that says "set autocommit ", who will then commit automatically after the DML statements successfully . It would probably have a commit and disable autocommit at the end of the script, in the case where the following script awaits undertakes to behave differently.

  • How to choose destinations for counter/timer signals in NOR-DAQmx?

    In the document M Series DAQ
    M series user manual
    622 x, NI 625 x and the materials NOR x 628
    M series user manual
    July 2008
    371022K - 01

    appears on page 7-30:

    Counter/Timer default pinout
    By default, NEITHER-DAQmx routes counters/timers and outputs inputs to the PFI pin, shown in table 7-4.
    Table 7-4. 68 peripheral pins by default Counter/Timer pines NOR-DAQmx
    Counters/timers fail-safety connector 0 PIN (name)
    0 2 CTR (PFI 12)

    You can use these default settings or select other sources and destinations for the
    counters/timers of NOR-DAQmx signals. Refer to the connection counter signals
    in the NOR-DAQmx help or the help of LabVIEW in version 8.0 or later for
    more information on how to connect your signals for common counter
    measures and generations.

    I couldn't find any hint to the appropriate command of DAQmx in the "NOR-DAQmx C reference Help" to select other destinations for counter/timer signals in NOR-DAQmx.
    Please can you tell me the DAQmx command right? Thank you very much.
    I use the NI USB-6259 M material Series DAQ, BNC end unit.

    datafriend,

    If I remember correctly, you can "free" the output terminal of default counter by calling DAQmxSetCOPulseTerm and passing an empty string in the 'data '.

    Hope that helps,

    Dan

    Edit: You can also set this to any other valid terminal (IE... "Dev1/PFI0") and to send the output to.

  • How can I improve the rate of acquisition with daqmx and usb-6008?

    Hello

    I am trying to acquire data of analog voltage with a USB-6008. I'm under Labview 8.5 student on an HP laptop with a 1.33 Ghz cpu and 736MB RAM, apparently. I tried using the Daq assistant and the low-level Daqmx functions. My best results come with a task set in MAX for my analog input, and using the function 'Daqmx read' the 'unique double 1 d sample' value in a while loop. I insert the values returned in a table which built in the while loop, and then when I'm done, I check the number of samples in the table. In the test VI attached, I also use the time to Get before and after all loop. The best sampling rate I made using this method, is around 40samples/second. I have attached a VI below that illustrates this concept. In my actual application, the data acquisition code runs at a time while loop with 1ms, parallel to other code that controls the device I'm collecting data of. The sampling rate is roughly the same for my test below VI and my application program.

    The 6008 datasheet gives the sampling frequency maximum 10 kHz. I'd be happy with 2 to 2.5 kHz, or as soon as possible; I'm sure that I can achieve a little more than 40 Hz. My first idea was tied to the hardware, but the 6008 cannot make acquisitions NI hardware.

    My question is: How can I implement a faster sampling of analog voltages to a USB-6008 in LAbview? If I can't do it, is there another way I can taste the data more quickly?

    Thank you

    -SK-

    To the best of my knowledge, the USB-6008 can do timed equipment acquisition. Don't forget that this is a multiplexed device, so if you add 8 channels so the maximum you can set is 10 k/8

    If you are new to LabVIEW, I suggest that you try this sample program first
