Minimum pulse width needed for gating the counter

Hi,
     I have TTL pulses of 20 nanosecond width coming out from the two detectors at random times. I want to count the number of coincidence pulses.I am trying this with NI PCI 6259 M series card, by giving one signal to the gate of the counter and other as a source of the counter (Single Point (On-Demand) Edge Counting with Pause Trigger). When both source and gate are high then it should give the coincidence count.Can anyone suggest  
1) Whether this is possible to gate the counter with 20 nanosecond width pulse?
2) If above thing is possible is this the right way for looking coincidence counts?
Any help regarding this is highly appreciated. 
                                                                                                                                                                                                                                         Regards
                                                                                                                                                                                                                                          surya

I'm sorry I could figure out what was the problem.
And I also find the minimum output pulse width on the catalog (12.5nsec).
Thanks,

  • What is the minimum pulse width output for PCI7831R?

    I have a problem to generate the signal output by using PCI7831R.
    I have used Labview FPGA program and PCI7831R with my experiment.
    When I tried to output a signal which has a pulse width less than 2msec, Its pulth width becomes double or triple longer than I set.
        For example, if I set the pulse width 1msec, its output pulse width became 3msec...
                              But if I set the pulse width 2.5msec, its output pulse width is just 2.5msec.
    Internal clock is 40MHz and theoretical rate is 53.5MHz. And the cycle time of main loop is less than 0.5msec.
    (I believe those value are fine to generate the 1msec pulth width output.)
    My questions are
    -What is the minimum pulse width for PCI7831R?
    -Do you have any idea to solve this problem?
    I attached the picutre of my VI.
    (because this picture is a little old, It has broken wires. But it is fine now.)
    If conditions are all good, this VI will output the signal during "Injection Duration(micros)" micro-second.

  • Need to get the count based on the column availability

    You get a set of table names from a query, say
    select table_name from all_tab_columns where column_name like 'DC_I’;
    TABLE_NAME
    A
    B
    C
    Now, for the above set of tables (A,B and C), you need to get the count(*) for a single dc_i value (say XXX DC)
    In simple words, its like framing the following 4 separate queries into one single one:
    select table_name from all_tab_columns where column_name like 'DC_I’; (Based on this o/p, following 3 queries..)
    select count(*) from A where dc_i=XXX;
    select count(*) from B where dc_i=XXX;
    select count(*) from C where dc_i=XXX;

    Does the new ipad use pulse width modulation to control the brightness of the display? I have photophobia and migraines and am unable to use displays that use this technology due to it triggering a headache.

    You'll have to go to an Apple Store and view the screen to see if it's OK for you.  If a store is not convenient, buy one from Apple online and check it out.  You have 14 days to return it for a full refund, no questions asked.

  • Minimum DB2 resources needed for a WL ConnectionPool to DB2 on UNIX?

    I posted this same message to the DB2 group as well....
    I want to create a ConnectionPool to a DB2 database using the Weblogic
    App Server v6.1 running on UNIX/Solaris 8. The DB2 database that I'd
    like to connect to resides on a separate server(on Windows 2K Server)
    elsewhere on our network.
    What is the bare minimum required to install on the Unix machine to
    support this client connection?
    To configure the LIGHTEST posible setup on the UNIX machine, do I:
    Install the "DB2 Run-Time Client"?
    OR
    Install the "DB2 Connect for Unix"?
    OR
    Neither?
    After one of these is installed, do I: (again, what is the minimum
    required?)
    Do I need to create an instance? (with associated users & groups)
    OR
    Do I need to configure an Administration Server?
    OR
    BOTH?
    OR
    Neither?
    I know I need to include the db2driver.zip and the db2home/lib in WL's
    environment variables within the Weblogic App Server. Anything else?
    I have found the following settings on the web to configure the
    ConnectionPool but I'm unsure of a couple values:
    URL:          jdbc:db2:???? (not sure what to put here)
    CLASSNAME:      COM.ibm.db2.jdbc.app.DB2Driver
    PROPS:          (what are the Required (minimum) props for a connection?)
    user,pwd,server(?)

    If you use the DB2 driver from Data Direct, it is a type 4 driver. You only need 3 jar files
    (the type 2 driver from IBM installs about 60Meg of data on your drive).
    "Stephen Felts" <[email protected]> wrote in message news:[email protected]...
    Using IBM's drivers, you install the DB2 Runtime Clients V8.1 (multiple languages).
    Then you can follow the documentation from WLS 8.1 (even if running 6.1, except
    ignore the sentence about using the JDBC Connection Pool Assistant, which is new
    in 8.1b - you will need to type everything in yourself).
    The documentation has a sample excerpt from the config.xml.
    See http://e-docs.bea.com/wls/docs81/jdbc/thirdparty.html#1096721.
    The documentation also mentions using the Client Configuration Assistant.
    Using the DB2 command line processor, you need to enter something like
    catalog tcpip node <nodename> remote <servername> server <port_number>
    catalog database <databasename> as <aliasname> at node <nodename>

  • What is the BO for Over-The-Counter-Sale?

    Hi guys,
    I wonder if anybody can tell me where to find the BO in the repository explorer.
    I appreciate your help.
    In general it is very difficult to find a BO at all. The customer wants a Workcenterview to be changed, so do I start to make an analyze if the change is possible.
    But for the first analayze I need to know the BO. How can I determine this in general, do you have any suggestions for me?
    Thanks in advance
    Erhan

    If you need to change a Work Center View, your best bet would be to start with the Configuration Explorer.
    There's a number of Over The Counter Sales screens located in SAP_BYD_APPLICATION_UI -> crm -> cinv
    Such as CustomerInvoicing_InvoiceRequestsOverTheCounter_WCVIEW

  • Minimum Database Priviledes needed for Database Connection

    What are the minimum DB Privileges I will need to do the following in JDev:
    1 - Brows tables and packages via the Application Resources - Connections - Database view?
    2 - Generate Business Components from Tables? (Query for Tables returns no values, or errors.)
    I'm using JDev 11.1.1.1.0. connecting to an Oracle 10g database.
    I can connect successfully but can't get table/view lists in the above scenarios.
    I can query tables directly (select * from.....) via the SQL_Worksheet form and I receive context help (e.g. on table names).
    Other connections to a local XE database works fine (CONNECT and RESOURCE privileges).

  • Single keyboard shortcut needed for doing the Mail PDF

    I very frequently e-mail Word files (using Apple Mail) as PDFs. However, it takes two long steps (Print Command and pulldown to Mail PDF command). I want to have one single keyboard shortcut for doing the Mail PDF.workflow command from within Word and not have to use the mouse at all. Any ideas?

    Maybe you can script it with AppleScript Editor (in Applications)? I'm no AppleScript guru, but since you did not get any other response, I thought I'd mention it.
    Get to the point where you want to use your keyboard command. Hit Record in AppleScript editor. If those actions are scriptable (not everything is), they will show up in the window. Hit Stop when you are done. You should be able to save the script as an application.

  • Tool needed for creating the package structure

    http://javacentral.compuware.com/pasta/
    Please let me know if you guys know of something similar to this.
    Thanks

    No. There should be an option to 'import java sources' somewhere in the 'file' menu (I think). Unpack the WAR. You will need to locate the JAVA source files, and then import from ArgoUML. The classes will all come in. You simply have to drag which ones you want onto the applicable blank diagram(s) you create.
