Measure the time difference between a digital output and an analog input that responded to the questionnaire

Hallo,

I use the following system:

  • OR PXI-1044 with controller NI PXI-8109

  • OR PXI-2564 switch module to turn on the monitor of my test device

  • Data acquisition multifunction NI PXI-6259 to measure the signal that responded to the questionnaire jump

The two cards are the same - PXI trigger bus. For both, PXI-2564 and PXI-6259 I use DAQmx to set the reading and writing of the channels.

Now, I want to measure the time between the digital output, my unit turns and the analog input, which measures the response of my system.

I can't do work by myself, please help me!

I thank Ludwig.

Hi Ludwig,.

If you can't give us any VI we have difficulties with to help you.

Because I Donat knowledge how your program is mounted it is not easy to know where you should enter signals.

Here's a question similar to yours:

  • What is the difference between these two JKM and when to use that one.

    Please tell the difference between these two.
    JKM Oracle compatible o JKM Oracle compatible (Date of update)

    Basic difference is in the obligation.

    JKM Oracle compatible (Date of update) wants a DATE/TIMESTAMP column in the source tables (s) who will get inserted/updated updated by the source application. ODI will capture the data modified, based on the value of this column. Only the DELETION part requires a trigger to keep track of deletion happening at source one or more tables.

    Where as JKM uniform Oracle does not require any which TIMESTAMP column in the tables of the source (s). It uses triggers to keep track of the INSERT/UPDATE/DELETE happening in the source.

    Compatible JKM Oracle performance (Update Date) is preferable, because it will create a little over the head on your source system. SO if you have a DATE/TIMESTAMP column in the tables of the source (s) that gets inserted/updated by the source application, then go JKM Oracle compatible (Date of update).

    Otherwise search JKM consistent Oracle.

    Thank you

  • Time difference between extraction in bulk and standard fetch?

    Hello world

    I have performed below block in the SCOTT schema for the gap between the standard extraction and extraction block. I read that extraction is more standard fast recovery. How ever the results were opposed as shown below.

    Resut

    ------------

    PL/SQL procedure successfully completed.

    the extraction time is 114

    the time required for extraction bulk is 136

    Block I ran

    declare

    Well I run your code using Oracle 12 c and based on your query in your cursor may be the first time that it will be a little different but then I noticed your code and I wonder... WHY you BULK COLLECT within the loop?

    That's the whole point of the bulk to pick you up.  Get you ONCE... in 'bulk '.

    Here is your code changed on my db and my result set

    SET SERVEROUTPUT ON
    
    DECLARE
    
       TYPE owner_name_t IS TABLE OF all_objects.object_name%TYPE;
    
       owner_c         owner_name_t;
       object_name_c   owner_name_t;
       l_start         NUMBER;
       l_end           NUMBER;
    
       CURSOR c1 IS
          SELECT owner
                ,object_name
            FROM all_objects;
    
    BEGIN
    
       l_start := DBMS_UTILITY.GET_TIME;
    
       FOR I IN c1 LOOP
          NULL;
       END LOOP;
    
       l_end := DBMS_UTILITY.GET_TIME;
    
       DBMS_OUTPUT.PUT_LINE ('The time required for fetch is ' || TO_CHAR(l_end - l_start)));
    
       l_start := DBMS_UTILITY.GET_TIME;
    
       OPEN c1;
    
       --LOOP
          --EXIT WHEN c1%NOTFOUND;
    
       DBMS_OUTPUT.PUT_LINE('Fetching bulk collect');
    
       FETCH c1
        BULK COLLECT
        INTO owner_c, object_name_c;
    
       --END LOOP;
    
       CLOSE c1;
    
       l_end := DBMS_UTILITY.GET_TIME;
    
       DBMS_OUTPUT.PUT_LINE ('The time required for bulk fetch is ' || TO_CHAR((l_end - l_start)));

  • What is the most important difference between 3D Picture control and controlling the display of Simulator

    I want to create a simulation of 3D on the front panel, and I see that we can use a 3D image control or a display of Simulator control. It seems that each of them can be used at the same position. What is the most important difference between 3D Picture control and display of Simulator?

    Hi sfh1,

    You are right, I found examples of Robotics that use 3D photo control and display Simulator control to display a scene 3D on the front panel. After further research, it seems that control the display of Simulator adds additional features compared to the 3D picture control. The control displays Simulator allows the user to right-click control during execution and change the background color, draw fashion, draw contact, view the ID of robot, display sensor data, suspension of service Simulator and reset service Simulator.

    More in depth on these options and the display of control Simulator can be found here:

  • What is the difference between HP Photo Creations and Snapfish

    I've been curious.

    What is the difference between HP Photo Creations and Snapfish?

    Hi Jeff17866. The difference between these two services are the location, accessibility and share-ability of the recorded images. Snapfish is a photo on the web edition and sharing and belonged to printing HP service. You upload your images on the Snapfish site and share with other sites (Facebook, Flickr, etc) by selecting the appropriate options. The images are then stored on the cloud, and you will be able to access it from any device with Internet access. So, if you want to easily share your photos with your friends and family around the country, Snapfish is a great tool to do. HP Photo Creations is a photo editing software that you download to your desktop. You can edit your photos and order prints just as with Snapfish, but all pictures remain on your hard drive. They can be shared by downloading files on the sites you want the images appear, but you are not able to access it on other devices. -Chauntain
