Is it possible to capture/capture a pulse of 100 ms by usb6008?

Hello

It is possbile to get a pulse of 100 ms (peak value is about 2 ~ 3V) by usb6008? The detailed signal is attached photo, the signal acquired by USB6008 in differential mode, 1000 sample rate.

Yes, max sampling rate is sufficient to signal 100ms pluse. But now the problem is how capture/capture this signal which appears only once.

I think that USB6008 has a PFI can use to trigger. But this trigger supports any numeric type, despite everything, I also try to trig to start to acquire signals by the PFI. But still fail to reach the goal.

In any case, no need to measure very high precision on this impulse, impulse detection is enough here.

In the end, as the topic "is it possible", or any other suggestions? Please advice, thank you.

Colin,

You can certainly capture such an impulse. If you set the AI for continuous sampling at 100 Hz or faster, then read all available samples about 5 - 10 times per second, you can capture the pulse. For a clean signal as shown in the image, just make a Max & Min chart on each group of samples. When Max > ~ 1 V, then you found the pulse. The index and the sampling period can give you the time of the pulse. Occasionally, you will be able to capture the part of the pulse to a reading and the rest of the impulse in the next reading. Dependingon your application, you may need to add some logic to handle this situation.

  • Possible to capture directly from the monitor?

    Hello

    Is it possible to capture video directly from my computer screen.  I want to create a video tutorial on the execution of certain programs.  I don't really know anything about video software, I bought the CS5 master collection for other programs.  So, I was just wondering if any of them can do it before I spend $ 40 on FRAPS.

    Thank you.

    Find out CamStudio; It is a program free registration form.

    Note that if you use the CamStudio codec, you'll have to transcode the files to a different codec that CS codec is not 64-bit. You can also Google for 64-bit screen capture codecs and the use of those.

  • It is possible to capture the lines of delete with the CHECK feature operations?

    10.2 using triggers I can connect the deleted lines, but is it possible to capture the lines of delete with the CHECK feature operations?

    Thank you.

    You can find Fine grain auditing and capture strategy audit records (for example, access to a column), and also capture the SQL text.

    But that still won't 'copy' on all lines accessed by the user who runs the verified order (for example a DELETION).
    If you want to "save a copy" of the row that has been deleted by a user, you would still have to write your own trigger ON DELETE.

  • Captivate 8 - is it possible to capture Captivate while using it?

    I created a series of how-to - Captivate, using C8.  I would actually like to capture myself performing specific tasks in Captivate - add effects, for example - as part of this series of How - to's, I was asked to create.  I tried to create a software simulation of C8 however, I cant seem to get C8 to stay open while I try to capture use.  Is there a way to do this?  I thought maybe open two separate sessions of Captivate, but I don't know I can do... ?

    Any suggestions?

    Hello

    You should be able to capture most of what you need. But what you will not be able to do is to enter the capture process. Think about using a physical camera to take a picture of himself. It's like that.

    Two instances should be thin.

    Dismal Hello,

    I'll try to point you in the right
    direction to start coding the application, but do not forget my
    suggestions have to be modified to your specific request.

    For
    the task output redeclenchables finished meter you need to
    your counter seconds in this application, I suggest to take a look
    in the Finder example in LabVIEW ('Help' are examples) and less
    DAQmx hardware entry & exit"" generating digital impulses.  Here,
    you will find some Gen dig Pulse - Retriggerable.vi.  You can use this for
    Create your door 4 pulses ms it's over (not a pulse train) and
    redeclenchables (for each time you go to the next step.

    In
    regards to the configuration of the first counter, there are several things to
    consider, and I can offer initial help to get set up.  You
    in-house allows to route internal CTR1 (4ms of pulse) output for your CTR0
    Door to measure only during the time.  Here are additional
    Info
    to do this in LabVIEW.  The source of your task of edges ABOVE County
    will be the TTL signal you are measuring and counting.  It comes
    on the PFI line that corresponds with CTR0 Source.

    When
    you make a measurement finished with CTR0, you will take only heads while
    the door is high and your source has a rising edge.  You can set the
    measure over to start on a trigger, which is not clear in this
    for example, that you have identified.  Since you know that you have a finished 4ms pulse
    time to measure, you can set the duration of your measure
    as a result.

    I found this
    Forum
    which may help some, but the coding is
    textual.   I hope this can give you a good starting point for
    programming.

  • How do I capture the output of voltage full bridge with Signal Express NI9219

    Hello.  I'm trying to do and calibrate a load cell with the installation of full-bridge strain gage.  I use a NI9219 module with a cDAQ chassis.  Is it possible to capture the actual output voltage?  Signal Express gives me a value of strain, but I really need to know the output voltage.  Where to look.  I need only two channels for full-bridge.  I think that could connect the wires to the two remaining channels and read the output voltage of the strain gauges which would be connected as a tension of the 9219 entry, but I think that Signal Express could give me the voltage and output voltage directly.  Any input would be appreciated. Thank you!  P.S. I only use this equipment on occasion and am not the more familiar with it, so keep things simple for me.  Thanks again.

    Hi jgh@AET,

    The NI 9219 measures the ratio of voltage full bridge in hardware sensors, allowing any variation of the voltage to cancel. You won't be able to measure the output voltage of the sensor regardless of the voltage without additional channels, but you can measure the ratio of raw tension using the type of Bridge (V/V) . You can also use the type of measure of Force (bridge) measurement of load cell with engineering units (N, lb, kgf, no strain).

    This screenshot shows where the two Bridge (V/V) and Force (bridge) can be selected in the DAQ Assistant:

    These types of measurement were added sometimes around DAQmx 9.1, so if you have an older version of NOR-DAQmx, your DAQ Assistant maybe not them. The latest version is currently 9.4 of NOR-DAQmx. Front of NOR-DAQmx 9.1, the approach to recommend to measure the load cells was to use the custom with Excitation voltage type and a custom scale. However, Tension Custom excitedly can't Bridge of calibration in the DAQ Assistant.

  • How capture and save a sequence continues to images using NI 1422 LVDS card capture, through Measurement & Automation Explorer?

    It is possible to capture and record a sequence of images with a LVDS OR 1422 EZMaker using Measurement & Automation Explorer?  Everything is installed correctly and running and I am able to use the "Snap" command to save an image, as well as the 'Grab' command, but it seems that you must stop the dump command before you can save anything, and it only allows you to save the final image.  Is there a way to record a sequence that is being caught, or should I use LabVIEW or other additional software to do this?

    Kind regards

    James S.

    Hello James,.

    You will need to LabVIEW or another environment development in order to record a sequence of images. If you have LabVIEW and the Acquisition of Vision software, you will be able to capture and save images in an AVI file. There are examples that come with the Acquisition of Vision software that can do this.

    I hope this helps.

    Not sure this is the right forum - questions about the place where questions MM led me here.

    One, when I capture video, I hear no audio.  How can I get it to play the audio during capture?  I'm probably stupid but not stupid enough to not to increase the volume.  Two, it is possible to capture audio only - or perhaps extract audio from the video?  I need audio segment, but can only capture video with audio.  Bonus points: MM is on Windows 7, right?
