How to sample a data input waveform with a trigger input waveform

Hi,
I am using the NI USB-5132 digitizer to receive two inputs: one is an analog data waveform and one is a digital trigger waveform.
Is there a way to generate a third waveform/array of data that corresponds to the data waveform being sampled only once per rising edge of the trigger input?
-Thanks

Timothy,
First of all thanks for the reply, I've been really busy this last week and haven't been able to reply.
Right now I have my data signal on channel 0 of the NI USB-5138, and I have the trigger on channel 1.  I have attached two corrections of how the signals look coming in (one is zoomed out, one is zoomed in, trigger is the red one the zoomed in one).  The trigger signal has 128 square pulses per scan that correspond to the time that I would like to sample 128 different high values for the data input.  I also have a 3rd input which has a falling edge for the start of each scan. As you can see in the zoomed out waveform graph, the data input consists of consecutive scans of data. 
My end goal would be to process the data so that I have 128 different arrays of 10-20 data points (each data point represents a different scan), with each of the 128-array corresponding to a different element in the 128-long scan, and how it has changed over time.  So for example, if the data at array location 3 changes from 0 V at scan t0 to 2.5 V at scan t1, then back down to 0 V at scan t2, then I would like to have an array that looks like:
Array of data for location[3]
Time:         t0    t1     t2
Voltage:     0     2.5   0
My biggest challege has been setting up these arrays.  Would it be best to capture 10-20 scans using the 'Acquire N Samples', and then do post processing?  I also experimented with the PtbyPt VIs, which seem interesting because I would like to do as much of my work in real time as possible, but I'm not too familiar with these or with Labview.
Any help would be much appreciated.

    how do I connect to a TV with a HDMI input? Can I use a USB graphics adapter?

    Here are the specs for your HP Pavilion All-In-One MS235 Desktop Computer. Based on the specs, your computer doesn't appear to have a video output of any kind. A USB-to-video adapter such as the EVGA UV Plus+ UV39 will be required to connect your HDTV to your computer.

  • How can we check data in r3 with that of  BI Report?

    Hi All,
    I have data in report.
    I have to compare that data in the report  with that of soure data(r3).
    in the source when i got to rsa3 and give the data source i am able to see total number of records but no the data.
    1)How can i see the data coming for spefic field or all the fileds which are data source?
    2)For one field i am getting data for infoprovider but not in the  report?
    Thanks all.

    Hi....
    I have data in report.
    Hope this report is developed based on MultiProvider ..
    I have to compare that data in the report with that of soure data(r3).
    in the source when i got to rsa3 and give the data source i am able to see total number of records but no the data.
    Once its shown number of records then click ALV /  List which will show your the records...
    1)How can i see the data coming for spefic field or all the fileds which are data source?
    To identify the this , please check the mapping of field in between Data Source and Target... then go to your target list the data...
    2)For one field i am getting data for infoprovider but not in the report?
    If  your report developed based on multi provider , and even you can see data in multiprovider , hard filter would be the issue ....
    ---Thanks

  • How do I enter data in excel with a specified number of decimal points?

    I have several inputs that are being written into excel using the "Write to Spreadsheet file" vi. One of my inputs only writes to excel with 3 decimal points. I would like it to have four, how do I change this?

    Pop-up on the top input to the "Write to Spead...." labled "Format".
    Chnage it from the default of "%.3f" to "%.4f"

    beacuse i have pass in default system date it's working only with add row button.
    How can i pass system date and time in update mode in tabular form.
    Thanks

    Hi,
    You just create a trigger on the table on which you build your tabular form:
    e.g:
    CREATE OR REPLACE TRIGGER  "AUDITING"
    before insert or update on "MYTABLE"
    for each row
    begin
        if inserting then
            :new.created_on := localtimestamp;
            :new.created_by := nvl(v('APP_USER'),user);
        elsif updating then
            :new.updated_on := localtimestamp;
            :new.updated_by := nvl(v('APP_USER'),user);
        end if;
    end;Regards,
    Fateh

  • How to lock the data for few periods in the Input Layout

    Dear All,
    I have an input enabled layout wherein I will display the data based on a period range.( For ex, 01.2007 to 12.2007).
    Now, based on the current period I should disable the input readiness for the periods less than my current period.
    In my ex, if my current period is 06.2007, the input readiness should be disabled for the periods 01.2007 to 05.2007 .
    How can I achive this?
    Regards,
    Srini.

    Hi Srinivas.
    You can use user variable exit for the disabled one (the period one); based on the current period..
    You can read regarding it in here:

  • How to delete the Data Points label with a crosstab layout

    Hi, just a question.
    I created a report which uses a crosstab layout; so...I have the Company Name on the left, Status Code above and the Count(tickets) as Data Points.
    As soon as I put the Count(tickets) inside the report, the label "Data Points: Incident Id Count appears above just at the bottom of the Status Code
    Is there a way to avoid this tedious label ?
    As workaround, I changed the Data Points' format heading (text and background) in such a way to see only a Grey space...but this is not so useful (from the customer side...)
    I also looked for inside the crosstab layout properties...but I didn't found nothing.....
    Any help will be appreciate
    Alex

    Well, I think you are out of luck. You are basically saying you want to control when you have a column heading and when you don't want to have a column heading. Most of us users do want column headings in our reports. In fact I have a hard time trying to figure out why you don't want a column heading. How are the report users going to know what the numbers in the column mean if you don't have a heading on the column? Maybe the initial users of the report know, but what happens when they leave and someone else takes over their duties? I would suggest putting in an enhancement request for Discoverer to give you the option to not display a column heading, if you really want something like this. This needs to be at the workbook level, I am thinking.

  • How to i display data of piechart with legend names?

    hi, i have a pie chart where i'm showing data inside it..now,my requirement is data should be shown with legendnames like
    Catgeory1 (23)
    Category2 (76)
    where can i do this..thanks in advance..'
    lucky

    Hi lucky,
    If I understand correctly, you want to display legend name and filed value as data label in the pie chart. Suppose the Values field is Amount, Category Groups field is Year. Please refer to the following steps:
    Right click the data label in the pie chart, select Series Label Properties.
    Click the expression icon below “Label data:” prompt, and fill with expression below:
    =Fields! Year.Value &"(" & Fields! Amount.Value & ")"
    There is a screenshot for your reference:
    If you have any questions, please feel free to let me know.
