EVM measurement

Hi,
I have NI USRP 2922 and LabVIEW software. Can someone guide me how to make a coding for EVM measurement to measure the performance of transmit receive (point to point) signal??
Thank You,
Regards,
Mardiah

There are a number of things that could be going on. There could be other errors occurring, but you don't have any of your error clusters connected.
Next, a TCP/IP network is not deterministic. The amount of time it takes to do something can vary dramatically, What timeout values have you used? Are you sure the device is seeing the request and responding in a timely manner?
Related to that point, what is your network topology? Remember that you are sharing the network bandwidth with everybody else using it.

  • 2.7 GHz vs 6 GHz ... EVM Differences

    Dear NI RF HW Guys,
    I have a 2.7 GHz RFSA as well as a 6 GHz RFSA ....
    I see a huge difference in my EVM readings with the
    same Labview VI and same DUT transmitting a predefined packet.
    I am decoding my frames in 2.4 GHz band.
    I get favourable results in the  2.7 GHz RFSA.
    Can anyone explain why is this huge difference in EVM,
    when I have not changed my Labview VI and the DUT transmit conditions
    Regards,
    Dharmendra

    "Shouldnt EVM be same irrespective of HW differences ?"
     Not
    necessarily. Phase noise and amplitude accuracy have bearing on EVM and
    although I am not saying at this point that these are the explanations,
    HW difference makes a great impact on EVM performance in general. The
    digitizer difference between 5660 and 5661 most likely will not make a
    large difference in performance, and indeed you will notice the EVM
    specs for 5660 and 5661 are the same.
     "Andy, Just in case you were worried about signal saturation / clipping ...."
    I
    am indeed worried about saturation. You're generating a 0 dBm signal
    into an analyzer whose max input level has been set at -10 dBm. How do
    things change when you use the proper reference level of 0 dBm? You
    say you are capturing a clean RF signal and I am curious as to how you
    determine this? Visually by looking at the spectrum? Signal distortion
    leads to amplitude errors and amplitude errors are one component of
    what EVM measures. Do you see a difference in EVM between reference
    level of 0 and -10 dBm?
    Our EVM specs for QAM are
    listed in the 5663 specs and can be compared to 5660/5661 EVM specs.
    This data clearly shows the EVM performance of the 6.6 GHZ platform is
    better than the 2.7 GHz platform.
    One difference 
    between the 2.7 GHz platfrom and the 6.6 GHz platform is the amount of
    'headroom' between the stated reference level of the PXIe-5663 and the
    clipping level of the instrument. A -10 dBm reference level places the
    clipping/overload level @ 0 dBm on the 2.7 GHz platform. The same
    reference level would place the clipping level @ -4 dBm I believe (I
    could be off by 1 or 2 dB but not much more) on the 6 GHz platform. In
    any case, there is less headroom on the 6 GHz platform since the 6 GHz
    platform has 1 dB attenuation resolution (as opposed to 10 dB
    resolution on 2.7 GHz platform) and doesn't require as large an amount
    of headroom. This could very well be  your issue.
    As a
    test you should run generator and analyzer examples for the Modulation
    Toolkit, QPSK, and see what happens. Also, perhaps we can provide more
    assistance if you provide your code and the ability toreproduce the
    behavior you are seeing. If we can reproduce it we can figure out why
    you are seeing differences. At the very least I recommend using a
    correct value for Reference Level.

  • How to measure LTE signal EVM

    Ｈｉ　Ａｌｌ，
    I use R&S instrument(SG and spectrum analyzer) to measure LTE-TDD EVM,(Center Freq: 2.6G, power: -30dBm)
    But I am at a loss that I get the the value 87.18(EVM PDSCH 64QAM) , it beyond the limit 8.
    I donot know how to make it, can anybody do me a favor?
    And BTW, who can provide the remote commands for measure EVM, I want to use Labview to control it instead of manually.
    Thanks a lot
    Amanda

    Hi Amanda,
    Which specific Rohde & Scwarz instruments are you using?  We have instrument drivers at ni.com/idnet for a number of devices, including some R&S SG's and analyzers.  You can also download LabVIEW drivers at their website here.  These should help you interface your instruments with LabVIEW.  You should also make sure that you have NI-VISA installed on your machine.  You can search for, download and install the appropriate version of this driver here.
    Hope this helps!

  • Capture E4406 EVM measuremen​t screen

    Hi distinguished NI engineers,
               Nowadays , I attemps to setup EVM test in our lab. All seems ok except screen capture problem.From the E4406 programming manual ,this insturment supports screen capture functionality.
               This commands says it would provide a view of numeric results and a ploar constellation graph in the two windows.How i can realize that in labview, my experience for this is limited.
              Could anyone raise me a hand? Thanks.

    COMMAND.JPG ‏36 KB

    Hi Dennis,
                    Sorry for reply late. I will clarify something~~
    You seem to be asking a couple different
    questions. First, does the command work? I mean, does the screen change
    to reflect what you want?
    (The command really work.)
    Second, you are doing a read but you haven't issued any command to
    the instrument to send any data. You would need to issue a query (i.e.
    something with a '?' at the end.
    (I have already configured the command"DISPlay:EEVM CONStln" to the VISA write. Do you mean i still need to issue the command to Visa Read before get the expected graph?)
    Third, you mention a screen capture but you are not issuing any
    command that tells the instrument to perform such an operation. That's
    a command you will have to look up and then find the command to
    transfer it to the pc.
    (I already issue the command"DISPlay:EEVM CONStln" command to perform the command and also configure the measurment before display the screen.I was a bit lost.What kind of command you think i need to put it into? Because i think the sequence is clear:configure the measurment-->conduct the measurement-->capture and display the result.)
    Fourth, when you finally do issue a query and do a read, you will
    have to convert the string returned into numeric data before it can be
    displayed on a graph.
    (Yes ,I'll remember this rule to get the graph.)
    Fifth, a LabVIEW graph will not correctly display a polar plot. You
    will probably have to use the picture indicator to display this. Look
    at the shipping examples. Do a search for 'polar'. You may be able to
    do a normal trace on the instrument, fetch that, and display the data
    in LabVIEW without setting up the instrument to do it. I suspect this
    will be faster than setting up the instrument, doing a capture,
    transfering the capture, and then converting the capture to be
    displayed in LabVIEW.
    (All i want is to capture the whole measurment screen, Do you think it make sense?Maybe i do not care whether it's a polar plot or other kind of graph.)
               Thanks a lot for your replay and patience.

  • How to measure performance of supplier when using scheduling agreement ?

    Hello all,
    My client has an absolute need to be able to measure the performance of its suppliers based on delivery dates and delivered quantities. That is to say he needs to be able to compare what dates and quantities were asked to what has been really delivered.
    Most of the procurement processes used are based on scheduling agreements : schedule lines are generated by MRP and forecast is sent to supplier while firm requirements are sent through JIT calls.
    It seems that when doing GR in MIGO, it is done against the outline agreement number, and not against the call. Therefore, we have no way to compare dates and quantity with what was expected (in the JIT call).
    Do you know if SAP proposes a standard solution to this, and what could be a solution to this issue ?
    Thanks for your help
    E. Vallez

    Hi,
    My client faced the same problem and we ended up developing an own analysis in LIS. Since the GR is not linked to specific schedule line (SAP does some kind of apportioning, but it doesn't have to correlate to the correct match), one needs to do assumptions. Our assumption was the closest schedule line, i.e. each GR is related to the schedule line with the closest date. Then all GR the same day are totaled together before the quantity reliability is calculated, since the very same shipment can be reported through several GR transactions in SAP (one per pallet).
    If anybody has info about what SAP has to offer in this question (or is developing), please tell us!

  • Possible to limit dimensions and measures when creating presentations?

    We are trying to use OLAP/BI Beans to add BI functionality to our next-generation data warehouse application. This application has its own security framework, with the ability to define permissions/privileges for objects. We need to integrate BI Beans/OLAP with this security framework.
    One of the things we need to do is control which OLAP objects (like dimensions and measures) are available to a given user in the Items tab when creating a presentation. For example, user A might see dimensions Alpha, Bravo and measure Charlie, while user B might see dimensions Delta, Echo and measure Foxtrot.
    We need to be able to apply these dimension/measure restrictions without using different Oracle users, with each having access only to their own OLAP objects. Our data warehousing application does not use Oracle and Oracle users to control security; it has its own internal frameworks for privileges/permissions. We therefore need to find a way to restrict access to OLAP objects in some programmatic way.
    Here's an example of how this might work:
    - I am a clinical analyst. I sign on to the data warehouse application. The data warehouse knows that as a clinical analyst, I have access to a certain list of objects and functionality across the application. One of the apps I have privilege to is the BI Bean Presentation Creation Application, so I click the menu to bring this up. I can now create BI presentations, but since I am a clinical analyst my list of available dimensions and measures do not contain any of the G/L, payroll or other financial OLAP objects.
    - If I signed onto the data warehousing application as a different user, one that has a financial analyst role, I might see a different set of OLAP objects when I run the presentation application application.
    So what we need is some API way to specify which dimensions and measures are available to a given user when they launch the presentation wizard. I've been digging through the BI Beans help and javadoc and have found a few things, but they aren't what I need.
    Here's what I found:
    - setItemSearchPath: this allows you to specify which folders are to be displayed. We want control at the OLAP object level, not at the folder level, so this doesn't work for us
    - setVisibleDimensions: this controls which dimensions are available in the Dimensions tab, not which dimensions can be selected in the Items tab. Doesn't work for us
    - setDimensionContext/setMeasureContext: These might work for us but I haven't been able to get them to retrieve anything yet. It also seems to me that these might set which dimensions/members are initially selected in the Items tab, not the list of dims/measures that are available for selection.
    Any assistance on this matter would be greatly appreciated.
    s.l.

    Reply from one of our developers:
    The get/setMeasureContext and get/setDimensionContext methods are currently only used by the Thick CalcBuilder (in a few limited scenarios) and cannot be used "to scope the dimensions and measures listed in Query and Calc builder based on user access rights".
    The scoping of dimensions and measures based on user access rights should be performed at the MetadataManager/Database level.
    This may change going forward as the real issue here is the static nature of the metadata and a general issue with the GRANT option within the database. So from the database perspective it is not possible to grant select priviledges on a single column of a table.
    The metadata issue is more complex as the OLAP API reads the metadata only once on startup of a session. The list of available measures is based on the GRANT priviledge, so for relational OLAP this limits the data scoping capabilities. In 10g, the metadata for AW OLAP becomes more dynamic and contained and read directly from the AW. Therefore, with an AW OLAP implementation with 10g it could be possible to scope boht dimensions and measures quickly and easily.
    Hope this helps

  • Error while defining alt unit of measurement in material master

    All SAP gurus,
    i am trying to define a alt unit of measurement in a finished material, the base unit of measurement is in MT, and the sales unit is nos. the conversion formula is 53 nos = 1kg i.e. 1MT = 53000 nos. as conversion can be done only with base unit of measurement i am giving 53000 nos = 1 MT, but system unable to calculate the conversion as it is not taking mere than 3 digit after decimal.
    e.g.    if 53000 nos = 1 MT
    then  1 nos should be = 0.000018 MT
    but system not taking this value as this value contain 6 digit after decimal
    suggest me what can be the way out? with detailed steps. can i increase the post decimal value or i have to define another middle alt unit of measurement (like KG). and if that is to be done then how.

  • Can not display long derived measure - ORA-33674

    I would need calculated measures for compiling some special URL, but there seems to be now way to have results longer than 60 characters. I tried creating the measure using AWM and using OLAP API. Both will result in:
    ORA-33674: Data block exceeds the maximum size of 60 bytes.
    ... so its not possible to view the auto-generated view any more. The whole thing seems to be similar to this [Cannot view dimension if description is more than 60 characters|http://wiki.oracle.com/thread/2121955/Cannot+View+Dimension+If+Description+Is+More+Than+60+Characters]

    This is similar, bot not quite the same problem as for attributes. In the case of attributes, the problem was bad defaulting of the VARCHAR2 length by AWM. To fix it is was just necessary to give an appropriate length.
    Your issue is more serious since it lies in the server itself, which attempts (badly in this case) to derive the data type from the expression. In this it determines that the data type is VARCHAR2, but it defaults the data length to 60 instead of deriving the length from the contents. I am not aware of any workarounds in 11.1.0.7 for this problem. CAST, for example, does not solve the problem. The bug is addressed in 11.2 beta releases, but it was a non-trivial project that is no likely to be back ported to 11.1.0.7. It may be possible to bump up the default of 60 to something higher, but this is not a general solution.
    The TO_CLOB error is due to the fact that the CLOB data type (and hence TO_CLOB function) is not supported by the AW. It is supported by relational tables, which is why it is listed in the OLAP API. It can be used, for example, in the mapping between cube and table as long as you resolve the CLOB into an AW data type again.

  • Triggerring PXI-4110 to measure 1 current value while HSDIO PXI-6552 generating waveform

    Hi,
    Some question about PXI-4110 to measure current while PXI-6552 is generating the waveform. 
    1. Let say, I need to measure 3 points of current values, i.e. while PXI-6552 is generating sample-1000, 2000 and 3500. On the edge of sample 1000,2000 and 3500, the PXI-6552 will send a pulse via PFI line or via PXI backplane trigger line. My question is, is it possible to trigger PXI-4110 (hardware trigger or software trigger) to measure current values at these points ?
    2. Let say I need to measure the current on 0ms (start of waveform generation by PXI-6552) , 1ms, 2ms, 3ms, 4ms... and so on for 1000 points of measurement, code diagram as shown at the figure below. It is possible for the VI "niDCPower Measure Multiple" to measure exactly at 1ms, 2ms, 3ms .. ? How much time will have to spend to complete acquire 1 point of measurement by "niDCPower Measure Multiple" ?
    Thanks for viewing this post. Your advice on hardware used or software method is much appreciated. Thanks in advance.

    Hi engwei,
    1. Unfortunately, the 4110 does not support hardware triggering. Therefore you cannot implement direct triggering through the backplane or anything like that. However, there are a couple of possible workarounds you can try:
    a) Use software triggering: Say your 6552 is generating in one while loop, and your 4110 is to measure in another while loop. You can use a software syncrhonization method like notifiers to send a notification to your 4110 loop when your 6552 has generated the desired sample. This method, however, will not be very deterministic because the delay between the trigger and the response depends on your processor speed and load. Therefore, if you have other applications running in the background (like antivirus) it will increase the delay.
    b) Use hardware triggering on another device: If you have another device that supports hardware triggering (like maybe an M-series multifunction DAQ module), you can configure this device to be triggered by a signal from the 6552, perform a very quick task (like a very short finite acquisition) then immediately execute the DCPower VI to perform the measurement. The trigger can be configured to be re-triggerable for multiple usage. This will most likely have a smaller time delay then the first option, but there will still be a delay (the time it takes to perform the short finite acquisiton on the M-series). Please refer to the attached screenshot for an idea of how to implement this.
    2. To make your 4110 measure at specific time intervals, you can use one of the methods discussed above. As for how long it will take to acquire 1 measurement point, you may find this link helpful: http://zone.ni.com/devzone/cda/tut/p/id/7034
    This article is meant for the PXI-4130 but the 4110 has the same maximum sampling rate (3 kHz) and so the section discussing the speed should apply for both devices.
    Under the Software Measurement Rate section, it is stated that the default behavior of the VI is to take an average of 10 samples. This corresponds to a maximum sampling rate of 300 samples/second. However, if you configure it to not do averaging (take only 1 sample) then the maximum rate of 3000 samples/second can be achieved.
    It is also important to note that your program can only achieve this maximum sampling rate if your software loop takes less time to execute than the actual physical sampling. For example, if you want to sample at 3000 samples/second, that means that taking one sample takes 1/3000 seconds or 333 microseconds. If you software execution time is less than 333 microseconds, then you can achieve this maximum rate (because the speed is limited by the hardware, not the software). However, if your software takes more than 333 microseconds to execute, then the software loop time will define the maximum sampling rate you can get, which will be lower than 3000 samples/second.
    I hope this answers your question.

    Noooo! Actually I too had d same prob wit my iPhone 4S. When I connect to my wifi network it won't get connected or it wil be grey scaled! I took it to d istore and since I had warranty they replaced my IPhone. It iPad charger has high volt than ur iPhone charger so when u connect wit it, there is a chance where large amount of current passes thru ur iPhone. So for sure it wil damage ur motherboard and its parts! Many said that iOS 6 or 6.0.1 or 6.1 was d reason for tis wifi prob! But apple never made its mistake wit it's software. If and only if u hav hardware prob u wil hav these sort of wifi prob Bluetooth prob! So best way s to replace ur iPhone!

  • [Forum FAQ] How do I create calculated measure using AMO in SQL Server Analysis Services?

    Introduction
    In SQL Server Analysis Services (SSAS), you can create a calculated measure in SQL Server Data Tool (SSDT)/Boniness Integrated Development Studio (BIDS). Sometimes you may need to create calculated measure by using AMO in a C# or VB project.
    In this article, I will demonstrate so how to create calculated measure using AMO in SSAS?
    Prerequisites
    Before create calculated measure using AMO, you need to ensure that the following components were installed in your server.
    The multidimensional database AdventureWorks Multidimensional Model 2012
    A SQL Server with SSIS and SSAS installed
    The AMO libraries installed:
    X86 Package (SQL_AS_AMO.msi)
    X64 Package (SQL_AS_AMO.msi)
    Solution
    Here is the detail steps to create calculated measure using AMO in SSAS.
    Open SSDT and create a new SSIS project.
    Drag Script Task to the design surface.
    Click SSIS-> Variables to open the Variables window and add two variables that used to connect to the server and database.
    Create a connection to connect to SSAS server.
    Rename the connection name to ssas.
    Double click the Script Task to open Script Task Editor.
    Add Connection and Database variables to ReadWriteVariables textbox and then click Edit Script button.
    Add AMO reference in the Solution Explore window.
    Copy the script below and paste it into the script.
    Dim objServer As Server
    Dim objDatabase As Database
    Dim strDataBaseID As String
    Dim objCube As Cube
    Dim objMdxScript As MdxScript
    Dim objCommand As Command
    Dim strCommand As String
    objServer = New Server
    objServer.Connect("localhost")
    objDatabase = objServer.Databases("AdventureWorksDW2012Multidimensional-EE2")
    strDataBaseID = objDatabase.ID
    If objDatabase.Cubes.Count > 0 Then
    objCube = objDatabase.Cubes("Adventure Works")
    If objCube.MdxScripts.Count > 0 Then
    objMdxScript = objCube.MdxScripts("MdxScript")
    objMdxScript = objCube.MdxScripts(0)
    Else
    objCube.MdxScripts.Add("MdxScript", "MdxScript")
    objMdxScript = objCube.MdxScripts("MdxScript")
    End If
    objCommand = New Command
    strCommand = "CREATE MEMBER CURRENTCUBE.[Measures].[Multipy Measures By 3]"
    strCommand = strCommand & " AS [Measures].[Internet Sales Amount] * 3, "
    strCommand = strCommand & " VISIBLE = 1 ; "
    objCommand.Text = strCommand
    objMdxScript.Commands.Add(objCommand)
    objMdxScript.Update()
    objCube.Update()
    End If
    objServer.Disconnect()
    Then you can run this SSIS package to create the calculated measure.

    Is this a supported scenario, or does it use unsupported features?
    For example, can we call exec [ReportServer].dbo.AddEvent @EventType='TimedSubscription', @EventData='b64ce7ec-d598-45cd-bbc2-ea202e0c129d'
    in a supported way?
    Thanks! Josh

  • Why writes LabVIEW only every 2 seconds the measured Value to a Excel (In a while loop with 100 ms tact)?

    Hi everybody,
    I use the myDAQ to measure speed, ampere, and voltage of a battery driven motor. (For Current measurement, i use a Sensor which outputs a 0-10 V signal). I placed all DAQ-Assitants in a while loop with a [Wait until next ms multiple] clock and set a value of 100 ms. I thougt, Labview will now write into my text file 10 times a second all values. In fact, as you can see in the attached text file, Labview only writes in a unsteady interval of 1-2 seconds a value, which is too less.
    The question: Did I do anything wrong, how can you create VI that writes you lets say 10 values a second into text file? Or is simply the DigitalMultimeter input of the myDAQ not able to sample a rate of 10 Hz? I couldn´t find any information in the specification handbook about the sample rate of the DMM?
    If anyone can help me would be great! Thanx a lot, Markus

    File I/O is not very efficient. I recommend that you do you file logging in a parallel task. Have one task do your data acquision. This task would then pass the data to be logged to the logging task via a queue. That way your file operations do not impact your data acquision. Also, express VIs are not very efficient. You would be better off accessing that directly using the DAQ VIs. The express VIs contain lots of steps that do not need to be done every time you call it such as initializing the device.

  • [svn:fx-trunk] 9407: Reordering the if-statement in isMeasureFixed() exposed that hostFormat can be null when measure() is called if styles changed and measure is done before the next commitProperties .

    Log Message:
    Reordering the if-statement in isMeasureFixed() exposed that hostFormat can be null when measure() is called if styles changed and measure is done before the next commitProperties.  This states test exposed this.
    We should rethink if we want to clear hostFormat rather than have a hostFormatChanged flag.  If there is no hostFormat at measure then it has to be fixed because there is no line break format to check for auto-size.

    Oh my god, it is too long! You definitely check out types, casting and especially ODP.Net (it does everything for you)... etc. They can help you to simplify your code. I do not have enough time to copy paste it to Studio and understand and solve your issue, so I got title of your message as your main question.
    In Oracle, you can create an autonumber field by using sequences object. This is really useful when you need to create a unique number to act as a primary key.
    Basically you can create a sequence simply typing;
    CREATE SEQUENCE MY_SEQUENCE;
    now you have a sequence called "MY_SEQUENCE"... Then, I advice you select a number from sequence;
    select MY_SEQUENCE.nextval from dual;
    I said I advice actually kinda must, although it called sequence, I cannot be sequential. Do not even try to predict the value. You can be sure that it is unique number so you can use it.
    Then insert you record and use that number part of your primary key. I think that's it. Have fun.
