Control of low level of the PXI-2596

How to control a PXI-2506 Mux 26.5 GHz Dual 6 x 1 chassis PXI-1042 a code 'C' with a minimum of drivers? We want to use our own code, not of LabView, just plain 'C '. Also, we prefer to use our own controller (Linix based) shipped without a slot for a PXI card (if possible). Is there like a simple series or ethernet interface to control the boards housed in the PXI-1042 chassis? The switching speed is very low, it is part of a manufacturing test system, we want to use the PXI-1042 with several 6 x 1 Mux inside for instruments RF switching in of the DUT.

Hi eirlund,

In response to your questions:

Is there a simple series or ethernet interface to control the boards housed in the PXI-1042 chassis?

  • Chassis PXI itself contains only the connections for the PXI bus and some timing and triggering and power for the cards. This white paper explains the PXI architecture in many more details: http://www.ni.com/white-paper/52018/en/

  • In order to be interfaced with the cards that you need to use a controller Embedded PXI or a remote control which allows you to use another computer in place and place an on-board controller. A remote control can be easier to apply to what you're after however there are some limitations regarding the use under Linux. More information on what the remote controllers can be found here: http://sine.ni.com/nips/cds/view/p/lang/en/nid/10359

We want to use our own code, not of LabView, just plain 'C '.

  • You should always use the relevant drivers for the hardware you are using, in this case NOR-Switch and NI PXI Platform Services if you are using a remote control.

  • These drivers work with LabWindows/CVI which adds additional tools to facilitate the programming intended for the material OR in C, this means that it should be possible to use these drivers of C, but there is less evidence for this

Also, we prefer to use our own controller shipped (Linux-based) without a slot for a PXI card (if possible)

  • If this is possible will depend in part on the question of whether the version of Linux you are using is supported. You can look into this further here: http://www.ni.com/product-documentation/52786/en/

  • In addition, you will need a PCI slot or a slot ExpressCard to connect to a remote installation program with

I hope that this information gives you somewhere to start to consider whether what you want to do is doable?

Best regards

  • Get information from the low level of the Subvi ni5660

    A quick explanation of the problem: I need to create several VI just to return a value of the PXI-5660 (ex: Center frequency, Span, etc.) while the entries are only a "VISA" and one "error in.»

    Detailed explanation of problem: I need to create multiple VI that the properties 'Set' or 'Get' of the PXI-5660 module (ex: the Central frequency value, get frequency, etc...).  Each VI must have a VISA in/out and in/out Error, but the only other present in/out should be the property of game/called.  Global variables are not allowed.

    One of the biggest problems for me is that ni5660 drivers do not contain a property node.  I managed to (apparently) set some of the properties by feeding only a single entry in the icon 'configure ni5660 for spectrum', but the only tool that seems to be able to output all information is the icon «MT get Attributes»  The release of 'MT get Attributes' does not contain many of the properties that I need good output.

    I tried to use the icon 'MT get Attributes' linked to "ungroup by name" which has the value "handle receiver.handles.niScope" which feeds on the reference to a property niScope node, hoping that I would be able to obtain information through the niScope 5660 (it seems that ni5660 software uses the niScope on a lower level software ", correct me if I'm wrong).  This VI finished, when put online with the 'ni5660 Initialize.vi' and ' ni5660 Close.vi, ' returned the error (-1074135028) with the explanation 'ID attribute not recognized.' ""  (The error occurred on the property node in the Subvi "Get the Central frequency")

    The goal is to make the action of PXI chassis similar to a HP8563E Spectrum Analyzer.  With this in mind, the list of attributes that I will need in the end to set and get (the separate VI) are the following: Center frequency, Span, window, number of Points, resolution bandwidth, level of reference, mitigation and time sweep.

    I apologize for my (very probably) simple question, but endless (I only started programming in LabVIEW there about 2 weeks).  If someone would be able to point me in how to make apparently PXI-5660 current property settings from thin air, I would be very grateful.  If more information or details are needed, feel free to ask.

    Thank you

    ....

    but unfortunately, I'm still at a loss, how to create a VI that "calls" that same property back and the fate, while using only 'VISA In' and 'In Error' as inputs.

    Located on how silly that statement. You want to create a function where (for example) you want to set the resolution bandwidth and do not want to pass as a parameter the name of the instrument. You have created the programming language that is able to read minds?

    You can use a function where you can pass a parameter in (or use a function that retrieves a parameter) or do nothing at all with the instrument. It is more complicated than that.

    There are tutorials available that can help yu with LabVIEW to learn, but I think that there are certain fundamentals means.

    Edit: Sorry, I may have misunderstood. to query does not require an entry but I don't understand what you want to query. The parameters of the instrument are all under control stripped - a program you or any other writing. Unlike a GPIB instrument, there is no one '?' command to read a rear frame. It is assumed that you know how the instrument has been configured in the first place.

  • OBIEE BI answers: measures bad aggregation at the top level of the hierarchy

    Hi all,
    I have the following problem. I hope to be clear in my English because it is somewhat complicated to explain.

    I did following:

    ID of drugs classified in quantity
    1 9
    2 4
    1 3
    2 2

    and drugs following table:

    Drug brand Id brand Description drug whose active ingredient Id drug whose active principle Description
    Aulin Nimesulide 1 1
    2 Asprina 2 Acetilsalicilico

    In AWM, I've defined a Dimension of drugs based on the following hierarchy: drug whose active ingredient (parent) - brand name of medication (sheet) mapped as Description:

    The active ingredient of drug = drug Active ingredient Id of my Table of drugs (pharmaceutical = Description of the active ingredient LONG DESCRIPTION attribute)
    Pharmaceutical brand Description = drug brand Id of my drugs Table (LONG DESCRIPTION = Description of drug brand attribute)

    Indeed, in my cube, I have traced pharmaceutical leaf-level brand Description = Id of the drug of my fact table. In AWM drugs Dimension is mapped as Sum aggregation operator

    If I select on answers drug whose active ingredient (parent of my hierarchy) and the quantity, in my view, after the result

    Description of the active ingredient drugs classified in quantity
    Acetilsalicilico 24
    Nimesulide 12

    indeed of the correct values

    Description of the active ingredient drugs classified in quantity
    Acetilsalicilico 12
    Nimesulide 6

    EXACTLY the double! But if I dig drug Description of the active ingredient Acetilsalicilico I can't see correctly:

    Drug whose active ingredient Description pharmaceutical brand classified in quantity Description
    Acetilsalicilico
    -12 Aspirina
    Total 12

    Aggregation of evil is only at the top level of the hierarchy. The aggregation on the lower level of the hierarchy is correct. Perhaps the answers also amount Total line? Why?

    I'm frustrated. I ask your help, please!

    Giancarlo

    OK your on 10G but the view of the cube and the obligation to limit the levels in the LTS in the RPD is valid in both.
    I think we found the problem,
    Go to each source logical table this logic table (x 2 in your case you have two levels) and on the content tab, window background ' use this "Clause Where" filter to limit the rows returned. »
    Open the expression builder, locate LEVEL_NAME according to your cube and limit accordingly, it is to say LEVEL_NAME = "BRAND_DESCRTIPION" for the aggregation BRAND_DESCRIPTION LTS and LEVEL_NAME = "XXXX" in detail, SFF, where XXXX is the name of level of hierarchy in your cube for details (leaves) records.

    Can you try that and let us know?
    Thank you

  • Lower right corner resize vertical scroll of trump if configured controls button to appear in the lower corner

    The place of my bottom right of the Firefox window is normally under the lower part of the bar to the right of the horizontal scroll bar and vertical scroll if there. The square is used to click and drag to resize the right side of the window and the substantive limits.

    This is when a web site up its vertical scroll arrow button in the lower right. I can't access the arrow key down with my mouse to cause the page scroll down a few lines at a time because when I point the mouse there, I get the resizing of the controls instead. Even if the arrow button is clearly visible on the screen, the controls resize are supported and I can't use the scroll control.

    Two example web sites display their willingness to arrow down while at the bottom of the window; TIME.com and GMAIL.com. I also saw two PDF documents in the browser, too, I have a vertical scroll bar all the way down and I can not use this button arrow down, because instead I get the North-West-South-East click to resize cursor instead of the mouse pointer when I try to use this button to scroll.

    Someone on the Google Help forum was not able to reproduce this problem, showing me the screenshots of his right lower mouse behavior. But there is no resizing control which covers access to the scroll bar.

    I use the latest Firefox, I have reset Firefox, dumping so all my Add-ons and parameters customized and gave only AdBlock Plus and Cookie Monster. And, when I asked a similar question.

    I'm running Windows XP, on his last days of support. This computer is not able to run something more recent, unless I run with Linux.

    Go to TIME.com, its vertical scrolling is in the lower corner and I get the resizing of the control instead of the mouse pointer arrows when I point the down key. If I disable the page styles on the view menu, I get a useful result that defines the end of the vertical scrollbar above the lower corner. If someone the idea of the style of the page (CSS) creates this problem for me.

    Go to Gmail, turning off styles gives me a useless output of nonsense, so I have to use the current page style.

    Can someone please give me some advice? This forum page has vertical and horizontal scroll above and to the left of the place of the corner down. I have access to all parts of the two scroll bars, as is done on most well-designed pages.

    My window - resize controls are always responsible for the place of the corner down even if vertical scrolling is supposed to be there.

  • Control PCLK when using the PXI-6534 in e/s mode

    I use ports 0 & 1 on the PXI-6534 in e/s model mode and also use output control in the mode of e/s to unstrobed for simple.  Users manual says in the mode of e/s model the PCLK control is not used, but the mode of e/s model seems to put down (or maybe he defines as an entry).  This a problem for me because I expect to PCLK to stay a high return which I set earlier.  Does anyone know how to set up the PXI-6534 in e/s model mode so that this does not affect PCLK... He's going to stay high?

    Thank you.

    Jim

    Hi Jim,.

    According to page 2 and 3 of the PXI-6534 user manual, if you configure a group to perform i/o, associated for this group synchronization control lines are not available in the form of additional data lines. The knowledge base, here, explains this limitation for the PXI-6534. In summary, port 4 is reserved once you are in e/s handshaking mode or a model and cannot be used as data lines additional unstrobed.

  • DRM Global prop node listed is not in the category for the lower level nodes

    Hello

    I created a global node property in a category as "derivative" and "overridable", and it seems to work fine in all groups of "alternate" and "alternate" hierarchies hierarchies.

    However, in the hierarchy of the HAND of the application of DRM, this same property of global node shows only in this category at the level of the SUPERIOR node. It does not appear in the category at any level lower node in the hierarchy of the HAND.

    Can someone help me with the problem? I need this global property to appear throughout the application of DRM in the hierarchy/Versions all groups/hierarchies/nodes

    Thank you!

    Hello

    See the definition of the property for the property assigned to the hierarchy node Type hierarchylevel property * and see if any node under evaluation there do not include property that you created in its definition of node type.

    If there are all these types of nodes, then you must include your property by visiting this particular node type.

  • Add a picture to the text in the text box to the location of the cursor through Actionscript and control its reference level

    If I want to add pictures to the location of the cursor in the text box, I need to use EditManager insertInlineGraphic. But insertInlineGraphic offers no parameter to control how an image is placed in the text, such as baselineShift.
    While InlineGraphicElement allows me to well control on image added how is placed in the text through properties such as baselineShift, but then there is no way to add this InlineGraphicElement object newly created as the location of the cursor in the text box!
    So, how do you overcome this limitation? How can I add an image to the text in the text box to the location of the cursor through Actionscript and control its reference level?

    Post edited by: DilipShah

    After you add the ILG, you can find the ILG element by textFlow.findLeaf (cursor location) as InlineGraphicElement and then change its attributes. Or you can just enjoy applyLeafFormat().

    FindLeaf is an important function for navigation in the TLF.

  • Change an attribute value in a table of the tree at all levels using the control button.

    Hi all

    I use JDeveloper Version 11.1.1.7.0.

    I have set up on my Table from the tree only when selected in the parent level also chooses the checkbox on the levels of the child associated with a checkbox, see my below base schema.

    My method to achieve this was to follow this guide... Andrejus Baranovskis Blog: box support in ADF tree Table different levels

    1. [Checkbox] status. Name | Employee ID

    -> 2 status [Checkbox] | Name | Employee ID | etc. | etc.

    -> 3 status [Checkbox] | Name | Employee ID | etc. | etc. | etc.

    What I want to do now, is once the box is checked at the parent level and all child nodes checkboxes are also selected, is on pressure of a command button, the value of my 'Status' column has changed through all the levels where the check box is checked.

    The default of my column 'State' is 'untrusted', it should be replaced by "Approved" once the Parent level checkbox is checked (which causes the child nodes also be checked) and you press a command button.

    I searched for some pointers on how to do so for some time,

    I was trying to think of a way to use the attribute of checkboxes that is a Boolean data type, there may be a way to create a method that checks if the Boolean attribute = true and where is the value of the Status column should be changed, the problem is to make it through all three levels of the table from the tree. But I can't understand it, any help would be greatly appreciated.

    Thank you

    Kind regards

    Jamie.

    Hi Jamie,

    I guess that you can apply the same idea that you used to update the Boolean attribute box of your iterator. This time you need to do is to iterate exactly same way but update the Status attribute. Have you tried to do this? So while the first course you'll hand over your boolean, check and update status accordingly.

    What keeps you from doing this?
