Using 6015 to measure acceleration

How can I use the "acceleration" option of the NI-DAQmx/Measurement Explorer to measure accelerations via the DAQ-Pad 6015?

Hello Zschocke,
it is not possible to measure acceleration with the DAQPads 6015/6016 directly. You only can measure voltage, therefore you need a "acceleration-voltage-converter" and you have to know which acceleration corresponds to which voltage.
If you want to measure acceleration try e.g. the SCXI 1531.

Using a Custom Measure w/ BI Beans

In order to create month-to-date and year-to-date totals, I have created a custom measure using the create_custom_measure procedure in the dbms_aw_utilities package. These two new measures, MTD and YTD, are simply cumulative sum functions applied over the date dimension. I have created this new measure as 'permanent' and it will exist beyond the current session, persisted in the analytic workspace views. I would now like to enable this new measure for use with the OLAP API and BI Beans so that I can simply display the measure along with my other 'static' measures. However, after refreshing and re-enabling the cube, the measure is still not available outside AWM.
Is it possible to use a custom measure with BI Beans? Is there a simpler way to accomplish this?
Thanks,
Jeff

You need to post this question on the database OLAP forum as the enablement for OLAP process is owned by the database team.
I presume you did run the 'enable Analytic Workspace for OLAP API and BI Beans' option from within AWM after you added the two new measures? If not you will need to generate the CWM2 metadata to register the new measures.
Hope this helps

Can I use xbootmgr to measure what causes a failure to present credentials screen after ctrl-alt-del?

Hello,
I have several machines that are producing the same issue that when a user reboots, they are greeted as usual with the "please press ctrl-alt-del to logon" screen. When that key combination is hit, the info screen is gone, but the "User
logon box" never appears. By never, I mean it doesn't appear within 2-5 minutes, and the users tend to hard reboot their computers (generally leading to more problems).
I've read that this can be caused by a variety of issues, such as DNS, cable, speed negotiation with the switch port, etc. However, I am interested in learning if I can use xperfmgr to determine the issue.
From my testing, the ETL is only written once a user logs on to the system.
The invocation I used is as follows:
"C:\Program Files\Microsoft Windows Performance Toolkit\xbootmgr.exe" -trace boot -traceflags base+latency+dispatcher -stackwalk profile+cswitch+readythread -notraceflagsinfilename -postbootdelay 10 -nopopups -resultPath C:\Boot_Trace
Is it possible to use xbootmgr to measure this situation?
Thanks,
Matt

Hi,
Yes, this tool could to be used to record the boot information.
Let's make clear something below.
1. Could you see this screen after pressing "Ctrl+Alt+Delete":
2. Did you mean that the password inbox disappear?
3. Could you see above login screen when you start the computer normally？
If all is Ok when you start computer, the xbootmgr.exe - trace boot is not applied.
Meanwhile, go to Clean Boot
to see if there is some third-party software to troubleshoot.

Using a Dimension/ Measure in a Where clause of Another Dimension/ Measure in IDT

Hi All
I am building a Universe using Information Design Tool. In the Business Layer, I need to use a created Business Layer Dimension (not Tables) in a Where clause of another dimension as follow:
Dimension: "Current Week No"
     SELECT
          budgets.dbo.Calenderweeks.WeekNo
     WHERE
          budgets.dbo.Calenderweeks.EndDate = convert(SMALLDATETIME, fn CURDATE()})
Dimension: "Last Week No"
     SELECT
          budgets.dbo.Calenderweeks.WeekNo
     WHERE
          budget.dbo.Calenderweeks .WeekNo = @Select(Dimension\Current Week No) - 1
The first dimension is working well. However, the "Last Week No" shows NOTHING (I do not get any value)
Anyone can explain why I am not get any value from the second dimension, and how I can use a Dimension/ Measure in a Where clause of another Dimension/ Measure ?
Thanks

Short answer:
Beware of object WHERE clauses. They are rarely (I'd almost say never) the solution to the problem you're trying to solve.
Long answer:
It doesn't work because you are inadvertently filtering the same value twice in two incompatible ways in the same SQL statement. Both objects SELECT the same column in the database. The first object uses a WHERE clause to set it to the current week. The second object attempts to use a WHERE clause to set it to the previous week, but does so by selecting the first object, so you end up with both objects in your data provider.
Remember that BO is going to place all the objects in your data provider in the same SQL (except of course where your context definition has ensured otherwise.), so you have two WHERE clauses in your generated SQL which attempt to find a line equal both the current week and the previous week... and returns, naturally, no results.
Rewrite it with a derived table (as explained in the response above) and you'll get what you want.

Using a javascript to change the font size used by the measurement tool

A couple years ago I saw a javascript written that would allow me to chang the font size used by the measurement tool in Acrobat 9. When the IT department deliverd my new laptop with Acrobat X Pro, they had wiped out the script and I am not expert enough to recreate it from scratch. Any suggestions? I believe it was in an older post by Dave Merchant, but I truly can't find the post or a way to recreate the script. Thanks for any help.

Executing this code from the JS console will change the font size of all the Measurement annotations to 20. You can change the value in the first line to use a different font size:
var newTextSize = 20;
this.syncAnnotScan();
var annots = this.getAnnots();
for (var i in annots) {
    var annot = annots[i];
    if (annots[i].type=="Line") {
        var richText = annot.richContents;
        for (var i in richText) {
            richText[i].textSize = newTextSize;
        annot.richContents = richText;

Use SE30 to measure performance in background

Hi,
I want to measure performance of an existing program by running it in background because it takes a really long time to run.
I m trying to use the "Schedule Measurements for user service" option from the menu. But when I click on the new icon after going to Schedule Measurements for user service menu, I get a short dump with message
MOVE_NOT_SUPPORTED.
on the following line of code of standard SAP program SAPMS38T
> convert time stamp l_ts time zone sy-zonlo.
My question is
1. Am I using the right option to measure the performance in bacground or is there any other way (except changing code to put log statements)
2. How can I fix the above problem.
Will give points to the right answer. Thanks for reading.

I generally use ST05 to measure performance.

Use GPIP for measure six point by six DMM at the same time

First Question
I will use GPIB for measure six point by six DMM at the same time. I will record the data in every mins.Could it avaiable? Is this method not accuray?
I aslo wanna to run 3 labview programme at the same. time.Each programme is same and use GPIB to measure by 2 DMM and 2 Digital In .Could i do this?

The first question is easily handled by triggering all instruments at the same time and then querying each in turn for the measured value. You can use eaither a hardware or software trigger (i.e. the gpib GET command). For your second question, are these 3 LabVIEW programs started by a single main program? How you want to run them will make a difference but in any case, the programs will have to have some sort of synchronization mechanism if you want measurements to be taken at the same time or if independent, a blocking mechanism to prevent simultaneous reads and writes. More details on the second question would help.

Using graphs in measurement studio

I have written in multiple languages, and this �easy� �user friendly� software package has left me completely stumped. How on earth do you put data in to a graph and display it????? Can someone please show me code examples of firstly how to shove an entire array of numbers into a graph in VB.net using the new Measurement Studio and secondly how I could update a graph plot with a next acquired sample. Please help

"Where would I find "Creating Measurement Studio Strip Charts, Scope Charts, and Graphs" document. if it is on the website it is extremeley well hidden even from its own search engine. Does this specifically talk about VB .NET and measurement studio"
You can find this topic, as well as several other conceptual topics about the Measurement Studio .NET features with VB.NET/C#, in the Measurement Studio help that installs with Measurement Studio. You can find this help in two ways:
Integrated into VS.ET 2003/MSDN Help - Go to the table of contents, then the "NI Measurement Studio Help" node.
Measurement Studio standalone help - Go to the Start Menu, then Programs->National Instruments->Measurement Studio 7.1 for VS.NET 2003->Measurement Studio Documentation
Once you're in the table of contents, you can find the topic above by navigating to:
- NI Measurement Studio Help
- NI Measurement Studio .NET Class Library
- Using the Measurement Studio .NET Class Libraries
- Using the Measurement Studio Windows Forms .NET Controls
- Using the Measurement Studio Graph .NET Controls
The topic above is the second link in the list. If you have Measurement Studio 7.1 installed, this link will take you directly there.
"Using Measurement Studio ActiveX controls I wouldn't even know where to start, there is no AxCWGraph on any toolbar."
AxCWGraph is the name of the interop wrapper that is automatically generated by VS.NET when you add CWGraph to your project, so you won't see it in the toolbox. WaveformGraph/ScatterGraph is what you should use in .NET applications if you have Measurement Studio 7.0 or higher. I only mentioned CWGraph because this was posted to the Measurement Studio for Visual Basic forum instead of the Measurement Studio for Visual Studio .NET forum, so it wasn't clear if you were using the Measurement Studio .NET controls or the Measurement Studio ActiveX controls.
"If NI could just stick an example of exactly how to use VB.NET with measurement studio on displaying data and the various options available and stick it for all to see on the measurement studio home page it would be great."
There are several examples that are installed with Measurement Studio 7.1. If you installed Measurement Studio to the default location, you can find this examples at:

MeasurementStudioVS2003
DotNET

"I write in over ten different languages and scripts and fluent in two of them. It worries me that I can't even find the front door let alone open it."
I can understand how this could difficult if you were not aware of the Measurement Studio help and examples. Is it easier now that you know about this content that installed with Measurement Studio? If not, what else do you feel is missing?

Labview 8 crashes when using Read Labview Measurement File

Hi All,
I am a new user for Labview. I installed Labview 8.0 from the CD (evaluation copy). I was just testing the sample code provided by NI. I opened the "Load from File and Display" example and I was trying to open the properties for the Read Labview Measurement File component when Labview crashed. I tried it a couple of times and everytime it happens the same way (when I double click the component or right click on it).
I am using Windows XP with all the updates done. In the Windows crash report, the application version is 8.0.0.4005.
Other problem I encountered is a missing component on the Input Palette (no DAQ Assistant present) and the Instrument I/O Assistant raises the error "Measurement & Automation Explorer or the Instrument I/O Assistant is not installed correctly. Please install these from the Labview Driver CD". For the last problem, I will try to run the Labview Driver CD, once I get it. But I am not sure if the DAQ Assistant will show up then or not.
Any ideas?
Regards,
Nick

Hello Nick,
While it is not my area of expertise, I would expect the DAQ Assistant would appear after installing the driver CD as you said you would be trying.
What caught my attention was the crash. The easiest way to resolve the crash is to delete the instance of the Read LabVIEW Measurement File on the diagram and place a new one from the Express Input palette (now called "Read From Measurement File"). In that situation, I would expect just pressing OK to accept the default configuration should work. The crash occurs in certain circumstances when the Read / Write Measurement File Express VIs are dropped from a previous version of LabVIEW and then their config page is opened in 8.0.x. This issue should be resolved in a future release, sorry for the inconvenience.

Has anyone tried to use labview to measure tcp/ip throughput between 2 computer using labview?

I was wondering is LabVIEW can be used to measure throughput of the ethernet connection between 2 computers. Data in Mbps such as uplink and downlink on the connection.
Thanks

I've included a link to an article for determining the maximum TCP/IP transfer rate in LabVIEW. You can download the example that is included in the article. This example VI measures the communication from a real-time target to a host PC, so you'll need modify it for your application. Please let me know if you have anymore questions, thanks!
Measuring the Maximum Amount of Data Sent Out of a Real-Time Target Device

What product(s) should I use to replace Measure?

Hello,
I have a customer who has been using Measure in Excel to communicate with GPIB and possibly DAQ devices. He has been experiencing unstability with Measure and is interested in moving away to another product. Which product(s) would provide the simplest transition? I'm interested in any feedback/ideas you may have.

Solved!
Go to Solution.

Much of what Measure does today can be pretty easily still accomplished from within Excel using the macro editor although it does require that you write some code to do it instead of using the interactivity that Measure provides. Measure includes a conversion utility that will convert a Measure task to Excel VBA which leverages some of the ActiveX controls from Measurement Studio. Alternatively you could use Excel VBA (or in newer versions of Excel, .NET) directly with our language interfaces for DAQ and GPIB. Again, this would require some amount of programming in Excel. We also have examples which show how to acquire data using LabVIEW and then send that data to a spreadsheet.

OBIEE - Reporting using different time measures - year - month

I have a request where the user wants to enter in an account period (YYYYMM - example: 200911). The report should display the YTD amount up to the end of that month, the same YTD amount for last year, and then show the amount for that month and the amount for the same month last year. So basically it would be:
YTD Amount (Year: 2009 Months: Between 1 and 11)
YTD Amount Last Year (Year :2008 Months: Between 1 and 11)
Month Amount (Year: 2009 Month: 11)
Month Amount Last Year (Year: 2008 Month:11)
I can get these to work independently. Like I can get the YTDs to work by themselves and the Months to work by themselves. I just can't get them both on the same report. I have tried setting these as level based measures, but when I do, the YTD Amounts are displaying the amount for the entire year (pulling in December data).
Any advice on how to achieve this?
Thanks.

Hi Raghu
Could you pls. let me know , the syntax how to use this.
User would select Year and Month from the Prompt and measures should be rolloup for the last year YTD. e.g the fiscal calendar is Apr - Mar . so if user selects 2012 - Jan , then last yr YTD should be caluclated from 2010-Apr to 2011 Jan.

How to populate column titles for y values when using Write to Measurement File Express VI with a tab delimited text-based .lvm file?

The .lvm file generated by the Write to Measurement File Express VI includes column heading titles for the y values, but they are a default value of "untitled". See attached example of a sample file when opened in Excel, the values in question are highlighted. Is there a way to specify the column titles when the file is written?
This is a similar question to this posting, which received a work around response to use the Write to Spreadsheet File.vi, rather than a solution when using this VI.

Sorry for the late reply. I was out of the office Friday.
You can do it, but the code can get rather ugly. Under the hood, the dynamic data type (the dark blue wire) is an array of waveforms. In your case, the scalar values you convert to a dynamic data type are being converted to an array of waveforms, each waveform having one element. You have two options.
Explicitly convert your scalars to one-element waveforms (t0=0, dt=1) and add the title before conversion to a dynamic data type.
Convert your dynamic data type to an array of waveforms and loop through them to add the column labels. The conversion blocks are in the Signal Manipulation Express palette.
I would recommend 2, since it is the easiest to add. It is also the easiest to run only on the first iteration. Just put a case selector around the loop, wire the selection to the While loop iterator, and set the case containing the label code to 0. The default case simply passes through the dynamic data.
My apologies for not including a screen shot. I am in the process of upgrading my machine and can't run LabVIEW. If you need one, let me know and I can post one tomorrow.
