Question on 4294A programming

We are currently trying to use Labview to create a virtual front for the 4294 has, however, we encountered several problems in our tests:

1. we noted that the 4294 may operate under a continuous (or groups) mode (internal trigger) that allows the unit measure the impedance of sweeping under a specific frequency for several cycles and we want to keep the data acquired during this period. So what we did was first to define the parameters of scanning, the Analyzer trigger and stored data after scanning. But it seems that the program ended before the parser finished its scan data, and the computer stored only a part of the impedance of the data for a scan cycle rather than the whole data required for all cycles. After reading the manual of the program, we found out that he was be a status register that we can use to detect if the parser has completed one or more scans. So we came up with the idea of storing data by checking the State of the registry: we treat data storage function whenever a scanning program is completed, pending the parser works under a condition of operation once the data was stored in the computer that you wear the Analyzer to measure the State. So if we choose to deal with the extent of this way, be aware the labview for control code to register. So can someone please advise us a few ways to make data storage with the "number of groups" or "continuous" mode or please provide us with the status code for the register control using Labview?

2. we have also planned to use the function 'Sweep list' and data stored since the multiple scans under the different frequency range. However, we didn't have no idea on how to set up the table and use 'Edit list', the command 'Add' to our Labview program. Can someone please help us also with the parameters of the list?

Thanks in advance

Right now, you're ignoring the complete operation and the status byte is not be read.  Have you looked at the code or not even looked at the VISA palette? The STB of reading is here. Open the trigger to send and look forward to the Subvi opc.

And why are you using the old driver instead of the current project-style driver?

  • This question is about programming in C. you please help me with a question that is.

    This question is about programming in c. can you please help me with an issue that is -

    Why do we write - printf ("r = c = %d %d sum = %d\n", sum c, r,);

    What we're trying to accomplish here by writing this.

    I also wanted to know why we write things within double quotes.

    The book programming in C I have, gave no information on this subject.

    The way if statements can be nested, of same whiles and fors can

    also be nested. To understand the nested loops how to work, watch the

    program below:

    / * Demonstration of nested loops * /.

    (main)

    {

    int sum c, r,

    for (r = 1; r<= 3="" ;="" r++="" )="" outer="" loop="">

    {

    for (c = 1; c<= 2="" ;="" c++="" )="" inner="" loop="">

    {

    sum = r + c;

    printf ("r = c = %d %d sum = %d\n", sum c, r,);

    }

    }

    }

    When you run this program, you will get the following result:

    r = 1 c = 1 sum = 2

    r = 1 c = 2 sum = 3

    r = 2 c = 1 sum = 3

    r = 2 c = 2 sum = 4

    r = 3 c = 1 sum = 4

    r = 3 c = 2 sum = 5

    In short, in C, a string enclosed in double quotation marks is replaced by a pointer to character to this string somewhere in memory.  The first parameter of a call to printf() is a pointer to the format string and the following parameters replace the % {(quoi que) the characters that appear in the format string.}  %d represents a whole argument of printing.

  • question re. records programmed in windows media Center

    I want to record a tv using Windows Media Center (WMC) series. I configured the tuner, WMC and took the series to record using the guide. My question is: what I must have WMC running in the background for the scheduled to start recording, or WMC itself will start at the right time? In addition, it will start my laptop? in other words, can I just turn off my cell phone (to save energy) and let and WMC invites you to my computer to start up and/or start WMC when programmed recording? Thank you!

    The laptop doesn't have to be on, but if it isn't then it must be in mode 'sleep'. If you do a full closed then media library will not be able to restart the laptop, but it can be awakened from sleep mode.

  • Very simple question and CVI-program

    Hello

    I just started working with CVI, and as far as I can see, the principle underlying the interaction between various components is similar as in Delphi. I made a very simple example (Application of User Interface), containing a square button and a digital. My idea was to push the button, after which the DIGITAL controller displays a number. However, I can't figure out how to build a change of the function that is executed when you press the button. I tried a double click, right click, etc, but I couldn't understand it. I hope my question makes sense.

    Have you had a look in Chapter 2 of the getting started manual?

    I upgraded my PC e9290f getting things and the new motherboard. my recovery disks don't work can cause of great change, I was wondering I do my own thing a bit of the new discs reading recovery. as I got the new windows 7 cd. I could download programs hp e9290f product page or are those tattoo on the motherboard like windows 7 so that it don't work?

    Hello:

    I have a solution for you if you want...

    If you can read the Microsoft windows 7 25-character product key, you can download simple Windows 7 ISO files to burn on a DVD for the version of windows that is installed on your PC, and which is listed on the Microsoft COA sticker on your PC case.

    Burn the ISO with the option to burn the ISO on your DVD burning program and burn it at the slowest possible speed that will allow your program. This will create a bootable DVD.

    Use 25 characters on the PC product key to activate the installation.

    The key will activate a 32 or 64 bit installation.

    Then go to the support of the PC and driver page to install the drivers you need.

    Link to downloads ISO of W7 is below.

  • Security IIS question - Blackberry Java program

    I'm really at a cross roads here, I have a Windows 2003 Standard Server, I need to make sure the user access the installation package for the phone is a member of our active directory, now the file is secured in IIS anonymous access disabled, authenticated access is set to 'Digetst of authentication for Windows domain servers' with the correct realm. The user can go to a site web page with internet explorer on a test computer and prompted for a login name, they put into their network and network password user name and authenticate OK and I know who they are. BUT on BlackBerry phones, any type of phone this is the case, when you are prompted, they put in the SAME EXACT INFORMATION and obtain unauthorized user, it's as if the phone cannot send or receive something. The IIS server has a valid SSL certificate until 2016 and a verisign certificate valid. Content expiration is dsabled. MIME types are correct for the deployment because program if I activate anonymous, anyone can install the program very well (which is not what I want, I'm not anonymous activated), I do not use any substance asp.net but this tab is set to the version 2.0.50272, which should have no effect on this problem. The directory is configured with read / access to the log and index this resource, it has its own pool of applications set to Scripts only, which is also very good.

    Why is it impossible with any configuration of browser on blackberries to authenticate?

    Well, let's say that you have described your problem now.

    I thought that you would say kerberos/ntlm authentication (which is similar, I read on the technet site).

    as far as I know the windows digest authentication is not supported on the blackberry browser, but do not hesitate to get this confirmed by your RIM support.

    Maybe you could go to with https basic authentication?

  • A question about the program of paint on Windows 7

    I used old paint in Windows XP, hundreds of times, I've now updated for Win 7 and I am very disappointed in the new version of paint.
    In short, yes it has some new features, but generally he went back, big time.

    Let me explain.

    In the past, let's say you want to draw an object, a certain color, with Win XP, you just select a color and draw your object, now there's all this color 1, color 2. Yes, you can always get what you want to do, but it is much more tedious, much less intuitive.

    Another problem, the undo function (a very common tool) is hidden in one of the menus, you must drag to your command bar, even with the zoom in, Zoom out, yes they are there, but hidden away. WHY?

    A big, big problem in the system of color fill. In the past opens a GIF, say you had a large surface area, and it was all the one-colour, with a click, you can change the color. Try this in Windows 7, and when you save the image as a GIF file, you get all the grainy areas

    With granular fill means that the color cannot be changed again. (except everything clear and re - fill which is darn time consuing, or save the image under a 256 color bitmap. The problem with bitmap, is there a huge file to GIF format size. NOT HAPPY

    In addition, the Eraser button. On Win XP, it was white, nice and simple. Now, he must tinker with what color you want the eraser to be square. Much more complicated, why don't you just have another gum that is always set to white? Have 2 erasers. Much less intuitive, much more tedious.

    In Win XP paint, want to resize something, it was easy to say tilt Thexaxis say 150 percent, but the axis is left unchanged. Now it's more complicated. They are locked in. I'm sure you can tinker and it immutable, but it's not simple and easy, much harder to do.

    My overall impression of the new paint 7 win, is that it is much more tedious and much less intuitive to use. NOT HAPPY.
    Yes, with practice I can work around probably many bad features, but probably it will take a lot of tweaking.
    It's more complicated and much less easy to use.

    This leaves still not resolved the fill color on a GIF chart feature. For example, suppose that you draw a hollow black square, depending on whether you fill the inside a color (XP there was about 16 colors or you could flood, perhaps more.) when you have saved the GIF image once again, the picture was clear and the embanked area was perfectly monochromatic. This allowed low size and the ability to change the color, if you want to. EASY.

    Try to do this in Win 7 paint, and the embanked area is grainy, when you save it. Even if you save the file as a GIF file as soon as you start. WHY SE PRODUCT. In win XP paint, I would start a new image and before I started one line, I would and then save it as a GIF, in this way when I recorded it again, all solid colors in areas would be unchanged. Does not work with Win 7 paint.

    Seems I have to get my old PC works again and use the XP on it to make my images.
    Side, I have made hundreds of sketches on Win XP Paint and know how to use so extremely well.

    There is another paint program, you might find useful:

  • [Noob questions] Model oriented programming OBJECT and event Flex

    Hello, I have two very easy questions for an expert - I think.

    (1) issue-oriented object

    If I have a

    UserElement extends the Image

    UserImage extends UserElement

    UserText extends UserElement

    ...

    UserSomething extends UserElement

    Each UserSomething derived from UserElement has an editElement method that can be placed in the superclass UserElement needs to look exactly because in this journal.

    Now, from the root of the Application, I have to call the editElement, but I'd rather not be forced to have a giant switch inelegant structure... There is a way to dynamically cast to the right class?

    (2) issue of event model

    I read the documentation and googled around, but if I have this structure

    Application

    Canvas1

    Control1

    Canvas2

    CONTROL2

    and I send Control1 event, the full path is Application > Canvas1 > Control1 > Canvas1 > Application. But if I need control2 to know that this event is FAILED, the only way I see is to call a method in the Application control2. Is this correct or there is a way to redirect the event in a way to broadcast?

    Thanks in advance for anyone who wants to answer

    maestro91,

    Answer, no, protected Alexander is very good and I used it in this way - protected is visible to inherited classes OK.

    You should be able to:

    var r: derivedClass;

    a = new derivedClass();

    function do_something (b: baseClass)

    {

    test to find out which class that I was adopted, then derived

    ((derivedClass) b) .editelement ();

    above must call the correct method

    }

    You must explicitly cast to ensure the right call gets shot, but you used baseClass as an argument, so you can send your derived through classes.

  • Question about concurrent programs

    Dear Sir

    We use the ebs r12 12.1.1
    When asked to stop to patch or... we just set the closing time. My boss just says I need to end all tasks running before issuing a stop and he has a good point. If other countries has been running simultaneous check printing or some programs MRP was when I stop and later to start the application, the result would be different? Let's say the mrp run from 19:00 and should be finished at 21:00
    If I plan a stop at 20:00 and lift the system at 22:00 by that time, the MRP Manager should continue to run and can ends at 23:00 at the moment it was average spend the time Manager MRP s/b done (21:00) and the result may not be usable.
    so common sense is to stop all the construction before the termination of the application. Is this correct?
    Can someone please give me some ideas on this?

    Thanks in advance!

    Hello

    in this case, if someone has a running job (work should ends at 2: 00) I didn't, when I issue a normal stop would expect work to be finished in 2 hours before every CM end...

    I think you must ensure that all procedures of CM were killed/Close to the BONE before stop you the database and other application services. You will find that there are active processes, this should give you an indication that some jobs are still running.

    and what happens if I kill the CM and when I rebooted the system continues to operate employment where he was arrested.

    In my view, ends at the request (not the session database relevant), and you will need to submit the request again.

    IIRC, these scenarios are handled in manual configuration. Please check and confirm.

    Kind regards

  • Question on logic programming behind the the Twitter app to display secondary listviews

    Hey guys,.

    I tried to find how I would implement the Twitter app drag function where you're displaying the main power and can slide to the right to view a list of food trends.  At first I thought maybe create a Listview with two ListItemComponents and then adding a listview inside each with my data but I have problems getting whatever it IS displayed.  I feel like maybe I'm overloading it?

    Ideas or comments on maybe an easier way to do this.  I currently have a little a segmented control that replaces the listview data source and it works, but I think this new way would look nicer and more intuitive.

    I use ListView with layout LeftToRight and SingleItem flick and works fine

  • Question about the program clearing browser history

    Aftre the class implementation and the instructions to import appropriate, I can access URL in an application using these instructions:

    {Private site = Browser.getDefaultSession ();
    site.displayPage ("http://www.whatever.com");

    Is not indicated some managers ButtonField, listeners and a group of if/else instructions that serve the U.I to select a half dozen of them hard coded URL.

    The problem is that whenever the user selects a URL, the selection to become a historic event in the history of the BB browser.

    If I have Import net.rim.device.api.browser.field.HistoryEvent, I would be able to eliminate all the history entries that accumulate in the history of the standard browser or that will not work with this ease of use of the browser?

    If you have done this, you have an example constructor and method of your implementation that you would share?

    Thank you.

    This is not supported.  You cannot programmatically change the browser history.  The class that you reference is designed to be used with a browser field, not the browser BlackBerry itself.
