Vertical offset and triggering on 5102 digitiser

How do I get two traces spaced apart on a graph when using a 5102 digitiser, I have tried adjusting each off set but the traces just disapear from the graph.
Is there something I need to set?
Any ideas
Also I am reading values from the graph using a couple of cursors, this works great for a constant signal from the digitiser, but when it is a single pulse the display disapears when the timeout expires.  
How can I get it to stay on the the display so I can move the cursors to display the values, also the cursors values don't change when there is no trace, they stay on the last value.
Thanks
Allan

Hi Allan,
What software are you using (LabVIEW, LabWindows/CVI, Measurement
Studio, Soft front panel...)? On the Waveform Graph control you should
be able to set it to stack plots, so you have two seperate plots on the
same graph. You could also have separate Y-Axis for each plot allowing
you scale them appropreately. If I know what software you are using I
could probably write a small example.

  • Configuring Vertical Offset of LeCroy WaveRunner 64Xi using LabVIEW

    I am using LeCroy WaveRunner 64Xi with its instrument driver downloaded from the NI website. When I run the example lcwave Acquire Multiple Waveforms.vi, the vertical offset becomes negative in the waveform I receive back from the oscilloscope. For example, when I enter the value vertical offset = 2.0 V, the oscilloscope receives it and displays the waveform properly. However, the vertical offset of the waveform returned to my pc becomes -2.0V. I tried to remove the negate value icon from the connector between lcwave Get Descriptor.vi block and Waveform Scale and Offset.vi block. It turns out that the vertical offset becomes doubled up, i.e. when I enter the value vertical offset = 1.0V, the waveform returned to my pc goes up by 2.0V. What could be the problem?

    Hi VPL,
    Alan from LeCroy Tech Support here.  I'm not exactly sure what you are seeing... Can you restore the driver back to its original state, and then reproduce the problem and send me an email at [email protected] with images from both the scope and the lcwave Acquire Multiple Waveforms.vi front panel?   (You can back up your current version of the driver by renaming its folder first)
    Two questions for you:
    1) What is "Waveform Scale and Offset.vi"?  This is not part of the driver, and may be your problem...
    2) What version of the driver are you using? See the readme file in the instr.lib/lcwave folder.  I'm using 2.1
    The problem certainly isn't with Get Descriptor; the decoding of the waveform has been in place for many years without any reported problems.
    Lastly, I ran the VI with the a 0 to 1V signals going into C1 and C2.  I find that the returned data matches what I see on the scope. (see the attached image)  (I tweaked the timebase and vertical scale constants that are on the block diagram of Acquire Multiple Waveforms.vi)

  • Problem with Roles and Triggers

    I'm having a strange problem with Roles and Triggers in Oracle. It's a little difficult to describe, so bear with me...
    I'm trying to create a trigger that inserts records into a table belonging to a different user/owner. Of course, the owner of this trigger needs rights to insert records into this other table. I find that if I add these rights directly to the owner of the trigger, everything works okay and the trigger compiles successfully.
    However, if I first create a Role and grant the "insert" rights to it, and then assign this role to the owner of the trigger, the trigger does not compile successfully.
    To illustrate this, here's an example script. I'm using Oracle 10g Release 2...
    -- Clean up...
    DROP TABLE TestUser.TrigTable;
    DROP TABLE TestUser2.TestTable;
    DROP ROLE TestRole;
    DROP TRIGGER TestUser.TestTrigger;
    DROP USER TestUser CASCADE;
    DROP USER TestUser2 CASCADE;
    -- Create Users...
    CREATE USER TestUser IDENTIFIED BY password DEFAULT TABLESPACE "USERS" TEMPORARY TABLESPACE "TEMP" QUOTA UNLIMITED ON "USERS";
    CREATE USER TestUser2 IDENTIFIED BY password DEFAULT TABLESPACE "USERS" TEMPORARY TABLESPACE "TEMP" QUOTA UNLIMITED ON "USERS";
    CREATE TABLE TestUser.TrigTable (TestColumn VARCHAR2(40));
    CREATE TABLE TestUser2.TestTable (TestColumn VARCHAR2(40));
    -- Grant Insert rights on TestTable to TestRole...
    CREATE ROLE TestRole NOT IDENTIFIED;
    GRANT INSERT ON TestUser2.TestTable TO TestRole;
    -- Add TestRole to TestUser. TestUser should now have rights to INSERT on TestTable
    GRANT TestRole TO TestUser;
    ALTER USER TestUser DEFAULT ROLE ALL;
    -- Now, create the trigger. This compiles unsuccessfully...
    CREATE TRIGGER TestUser.TestTrigger AFTER INSERT ON TestUser.TrigTable
    BEGIN
    INSERT INTO TestUser2.TestTable (TestColumn) VALUES ('Test');
    END;
    When I do a "SHOW ERRORS;" after this, I get:
    SQL> show errors;
    Errors for TRIGGER TESTUSER.TESTTRIGGER:
    LINE/COL ERROR
    2/3 PL/SQL: SQL Statement ignored
    2/25 PL/SQL: ORA-00942: table or view does not exist
    SQL>
    As I said above, if I just add the Insert rights directly to TestUser, the trigger compiles perfectly. Does anyone know why this is happening?
    Thanks!
    Adrian

    Hi Raghu,
    If the insert rights exist only on TestRole, and TestRole is assigned to TestUser, I can do the INSERT statement you suggest with no problems if I just execute it from SQLPlus (logged in as TestUser).
    The question is, why does the same INSERT fail when it's inside the trigger?

  • Function and triggers and procedures

    sorry to asking this question,
    In oracle. we use the function and triggers and procedure.
    for eg:
    if we wrote an trigger for a table. it fires at a time manipulating table. (database contains table contains datas and database also contains triggers likewise function,procedure).
    but my questions?: is
    In my database I kept only tables. no triggers,no function,no procedures. and
    i dont want to kept this triggers, function, procedures in database  Instead of i want to kept this triggers, function, procedures in business logic layers(middle tier)
    is it possible? .
    if yes means, how to write or where to write? please help me, or else send the guidance documents or blog releated to it.

    Subu123,
    the +1 related to Would be great if you can take step back and see the implementation from another angle. First see why do you need DB trigger/function etc.Then check whether it is possible to implement the functionality using ADF BC + feasibility study between 2 approaches(I didn't mean to invoke DB objects from business components, instead checking the feasibility of implement the same functionality in your EntityObj/ViewObj/Service calls )Before making a decision for or against holding fuctions, triggers and procedures in the DB, you have to get the whole picture.
    Think about a trigger outside the DB. What could this be and why or for what is it used?
    All the answers are pointing to 'lets keep them in the DB'. Now there are situation where you don't have a DB or are not allows to use it. Still there can be triggers, only they are implemented in a different way.
    The same can be said for procedures and functions.
    So you have to think about the whole problem and how each sub problem you have to solve work together to resolve the whole problem.
    I'm personally tend to keep the business logic the the DB if the business logic is already there (e.g. I have to migrate an old forms app).
    If I design a new app I tend to keep the logic in java. Only sequences (for generating ids) and some other stuff which is purely db related like cleaning up tables I keep in the DB.

  • Does the Modulation Toolkit support digitizers NI-PXI-5124 and NI-PCMCIA-5102?

    I am using a demonstration NI-PXI unit to determine if it will support the application I am trying to develop. I need to demodulate a signal and determine the Quasi-peak value of the demodulated signal. The Modulation Toolkit states that it works with the 100MHz class of digitizers. Does it also support the 20 MHz and the 200 Mhz class of digitizers (NI-PXI-5124 and NI-PCMCIA-5102)?

    Kent,
    The Modulation Toolkit is fairly robust. I believe that it will work fine with the 20 and 200 MS/s boards. However, these obviously have to stay towards the lower frequency end of the spectrum. The Modulation Toolkit is most powerful with NI's RF products and is designed to do so. However, as I said, I believe that since the MT stays mostly on the software side and does not care too much about hardware it will not care about where the signals are coming from and will work for you.

  • Java stored procedures and triggers in lite

    Hi
    We are using java stored procedures and java triggers in our application for oracle lite database 5.1.
    We would like to know whether these procedures and triggers are uploaded or associated with tables or not because triggers are not being fired for the tables.
    The question is - how to find the uploaded procedures and triggers in system tables.
    We dont find any tables like (all_objects, user_objects) for this in oracle lite system catalogs given in the documentation.
    thanks in advance
    yugandhar

    I don't have much experience with Lite, but I'm running 9i Personal Edition. Any information about triggers can be found in the "ALL_TRIGGERS" view. You will want to filter out any rows where OWNER = 'SYS' unless you created your triggers as SYS. As for procedures and functions, you can see what you have created in the "ALL_OBJECTS" view where OBJECT_TYPE = 'PROCEDURE' or 'FUNCTION', once again filtering out rows where OWNER = 'SYS'. To see the code of any procedure or function, select substr(text,1,80) from ALL_SOURCE where NAME = 'function name' ORDER BY LINE.
    Hope this helps!

  • Charts: Gap between Vertical Axis and the chart area

    Friends,
    I have a really wierd issue and I am sure I am doing
    something wrong.
    I am trying to align 2 charts that are placed vertically. I
    want to align the left vertical axis and the gridlines within them.
    Aligning the left vertical axis is easy and done but aligning the
    grids is becoming challenging and I have already spent a few hours
    on this problem.
    Here is a wrong chart image ...
    Wrong
    chart image
    The line of the LineChart (in the top chart) is touching the
    left and right edges where as the bottom chart bars do not touch
    the left/right edges. Due to this the gridlines are not aligned.
    I had managed to solve this problem but I am not sure what
    part of the code solved the problem. Here is the right chart image:
    Right
    chart image
    In this chart, the line of the linechart (in the top chart)
    is not touching the left and right boundary hence the gridlines are
    alignd with each other.
    I wonder what property of the chart controls the series
    touching the left/right vertical axis or boundary. Your help is
    appreciated.
    Thanks

    here is some more information ...
    I started changing some of the properties of the chart which
    I mentioned is a RIGHT CHART and this is what I learnt ...
    It was a CartesianChart hence it was creating the gap
    between the left/right vertical axis and the actual chart area
    (refer to the right chart image).
    I changed it to a LineChart and it started behaving like the
    chart in the WRONG CHART image.
    Is there a solution to this problem?

  • After update to O/S 7.1.2 my iPad2 is stuck on Vertical Orientation and will not shift to horizontal as it has in the past.  How can I get the flexible orientation back??

    After update to O/S 7.1.2 my iPad2 is stuck on Vertical Orientation and will not shift to horizontal as it has in the past.  How can I get the flexible orientation back??

    I agree with what FoxFifth has said, but I want to add a little to the discussion and put my own twist on the explanation.
    If you see a lock icon in the upper right corner of the screen - then the screen orientation is locked.
    Try the side switch above the volume rocker first and see if that unlocks the screen.
    If you are running iOS 7, swipe up from the bottom of the screen to get to the control center and the lock icon is in the row of icons at the top all the way to the right.
    If the screen is unlocked but still will not rotate, reset the iPad.
    Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the button
