question about the input impedance
Hello world
I tried to measure a voltage with internal impedance 10kohm source, and I connect to the source directly with the NI USB 6009. When the voltage source is 5.043V, the data recorded by labview are about 4.8V. I checked the manual of the USB-6009 case and found that the input circuit (see attachment). So I guess when the device was taken from data, it actually takes the data on the node of crossing and converted, then return with impedance numbers shown in the graph. That's why I'm given to me below that it should have been.
I was wondering is it possible to treat it, other than the calculation of return and convert it with correct impedance?
Kind regards
Jude
Hi Jude,.
you could use an op amp to boost your signal (1:1), one so reduce the impedance seen by the USB6009. You can also use some other DAQ hardware with a higher input impedance.
In the end, the conclusion is: you must choose your DAQ hardware according to the specifications of the signal source. You have selected the wrong hardware...

Establishment of environment of Visual Studio 2015 for the creation of plugins for InDesign CS6
Hello, I am currently developing plugins for Adobe InDesign CS6 and I am currently using Visual C++ in Visual Studio 2015 and I can't import Adobe environment in visual studio, because the available guide refers to Visual Studio 2010. Should which directory I pay to go to what parts of the SDK? Thank you very much.
Hi Jacob,
Some tips for you, VS 2015 is not recommended for dev environment. CS6 InDesign plugin. You will meet all kinds of issues if you use for creating plugins CS6 2015, are some of the issues you may face
- Compilation or linking errors
- Random crashes, while the plugin is running, if you manage to get that much.
The main reason for this is the different versions of libraries CRT used by different versions of VS, which used once all causes all sorts of compatibility issues.
I would recommend that you follow the recommended by Adobe in the SDK VS version.
Now in regards to putting in place the project settings, you must configure the following paths mainly to point to different paths of the SDK
- Include paths for the C++ compiler, these are directories that contain different header files. This will contain multiple paths, see the sample project SDK for more details
- Path for libraries that need to be linked to your project, see Linker of a SDK project.
- Include the path to the resource compiler
- Apart from this, you can also set the executable directories, as shown in the screenshot you attached. This is used to designate certain executables that are used during the accumulation of the generation of the project phase.
You could refer to the sample project SDK for details, I would recommend that you base your new project on a sample project of SDK software for beginners and once you are comfortable with the settings, you can go ahead and write your own project to project depending on how you like to your Setup project the configuration files. For more details on how to write configuration files for VS projects to do a google search on it.
Hope that this info gets you started.

directly in the bb browser vs pages showing the Visual Studio plug-in
I use Visual Studio 8 with the latest Sun Java and Beta 2 of the plug-in. I'm using 32 bit Windows 7... I know that it is not directly supported, but it doesn't seem to be most of the time and I don't have an XP or Vista machine that is imparted to me.

I had an old computer get taken out by a storm. I managed to save to computer hard drives and installed them in a new computer. I can see my programs MS Word, PowerPoint, etc. and Visual Studio 2012. The problem I have is to find the executables for these programs so that I can actually use them. Is there a work around or do I still have to pay for them? VS is a pro version and more than 2K last I checked! Am I missing just the files in a folder, that I don't see? I seem to be able to find the files exc for other programs. (Rosetta Stone)
Really, I don't want to buy these programs and will probably go to another (more accessible) suite of software, if necessary. I can write the code in other IDEs and use another desktop software which ensures the compatibility of the MS products if that's the case.Thank you for your time and understanding,HHYou cannot run programs from the old hard disk, they must be reinstalled on the new installation of Windows computers.
Apart from the home folder for Office who would be in the Program Files folder, directory on the original drive Setup performs a number of other things. It will make hundreds of changes to the registry, install many libraries and sign them and put some files in the Windows directory itself.
Also, if the version of Office that was on the old computer came with the PC, it's more likely to be an OEM license. As such, it cannot be installed or run on the new computer as a limitation of the original end user license agreement.

For some reason, the Debug button is missing in Microsoft Visual Studio 2010. The other buttons that are supposed to run your program are missing as well and pressing on F5 does nothing, so I can't debug my application. The other stuff are still there, it's just that the buttons that the Debug program are missing (other ways do not work as well).
You can get a faster response or better if you like in one of the dedicated Microsoft forums Visual Studio here:
http://social.msdn.microsoft.com/Forums/en-US/category/visualstudio .
Thank you. :)
(I'm sorry, but I can't move this thread for you because the two forums are working on separate platforms)

How can I create a Windows using NOR-DAQmx application in Visual Studio 2010 64-bit
Hello
How can I create a Windows using NOR-DAQmx application in Visual Studio 2010 64-bit?
I'm transferring a 32-bit application on 64-bit. In visual Studio, I added the 64-bit project configuration. He compiled the source very well but the reports link errors:

Any help would be appreciated.
Thank you

Hi LaserShore,
Think you that you added the 64-bit platform settings target according to this page? : http://zone.ni.com/reference/en-XX/help/372636F-01/mstudiowebhelp/html/64bitcore/
Already running 32-bit application? Have you changed references to the 64-bit version?
You use Measurement Studio? If so some features are not supported with 64 bit.
Also when you say that you have added the NIDAQmx.lib, did you follow this KB:http://digital.ni.com/public.nsf/allkb/38F67B28D995C6958625706E000C580C

TestStand 2013 is compatible with Visual Studio 2013?
TestStand 2013 is compatible with Visual Studio 2013? Has anyone used together?
Code modules you build should be compatible/executables, however integration between TestStand and Visual Studio 2013 (for help debugging and development, for example the code patterns, step in the input/output between TestStand and Visual Studio and includes the updated paths automatically in Visual Studio) may not work correctly in all cases since Visual Studio 2013 is out after 2013 TestStand.
My understanding is that most of the things do not work, a few known minor issues are integration of help file does not and TestStand to what version of Visual Studio, the projects that you specify for the source of a specification of the step code section are not recognize.
Hope this helps,

Re: Cannot install Visual Studio 2008 on Vista 32-bit
Hello
I have a satellite P200 with Vista Home premium SP1 and I need to install it on Visual Studio 2008.
When the install wizzard starts it checks the compatibility of the computer and could not return this:"Setup has detected that this computer does not meet the requirements to install this software. These conditions must be met before you can install Microsoft Visual Studio 2008 Professional Edition - ENU
Requirements and software prerequisites
Windows XP Service Pack 2 update information
You must install this service pack to complete the installation. Visual Studio requires the installation of this service pack before you install Visual Studio"So the only solution I have is to exit the installation wizard, so I can not install VS2008

Hi mate,
Sorry, but just because one person in a MSDN forum has randomly the same machine you, does not mean that there is a related problem of the machine. Technically in comparing it s absolutely the same material as in an office and so why Don t you contact Microsoft technical support?
It seems that it is certainly unwanted Microsoft and has NOTHING to do with Toshiba hardware or software, so please see MS support sites or give them a call, because it s THEIR software which won´t operate according to THEIR operating system.
Welcome them

Control CWAI crashes Visual Studio
I try to read analog data from a card PCI-MIO-16-1 and OR-DAQ 7.5 installed. I want to use the old driver, because that's what my other software uses. When I go into Visual Studio (Express 2015) and add the CWAI control to the Toolbox, and then add it to the Visual Studio form hangs shortly after. The version of the control CWAI is 1.4. I try to use the free control that comes with the NOR-DAQ driver. What causes Visual Studio to crash?

Bothering you check NOR-DAQ 7.5 is compatible with Visual Studio 2015 and the version of Windows you are using?

Lack of Visual studio 2005 console
I just tried to convert my cvi application to compile with visual studio 2005, the conversion of the CVI 9.0 Wizard. It seems to work in the sense that it interacts with my application labview correctly but the console is not displayed. Is there a setting in visual studio to make appear the my console?
Thank you
in Visual Studio 2005, open the project properties (menu "Project/properties" or right click on the project name in the Solution Explorer should be and select 'Properties' from the context menu). in the tree view in the left pane, select ' Configuration Properties/Linker/System '. on the right pane, the first option is "Subsystem": select the value "Console" to have a console appears, or "Windows", if you do not want a console.

Hello
I am trying to acquire an output of my DUT using the 6552 map, and the 6552 50 ohms default channel input impedance. It's pulling down of my output, so I want to change the impedance of 10K or 50K entry but I can't seem to do.
When I run the example of the input channel Impedance.vi and change to the 10K or 50K input impedance, it remains to 50 ohms. Similarly when I add the relevant property node (to change the input impedance) to my vi, remains at 50 ohms. I use the channel 0 as my string of acquisition and channels 1 to 7 as my production lines.
Any ideas?
Kind regards
Barry

In differential Mode input impedance
Hi all
When I bought the USB-6212 card, I was impressed by the high input impedance of it - 10 GOhm.
This is indicated in the specifications, as in between HAVE + and AIGND.
So, what is the input under differential connection impedance?
Hi Navneet,
The question you have posted is actually a matter of multifunction data acquisition. You should post these questions in the Forums Multifunction DAQ. You will get much more quick answers to questions that are displayed in the correct forums.
The input impedance, in differential mode is a little less, then twice the impedance of the AI referenced to ground. What this means, is that he will be GOhms ~ 20 to 19. The actual value is not available, because it's such a high input impedance.
Best regards

Strange problem with Visual Studio
Hello.
I hope to be in the right section.
For some time (I can't say precisely how much, maybe since I've upgraded to Windows 10) I have a problem with Visual Studio 2013.
In practice, after a few minutes, what is open (without doing special things, even just type code) goes down. comes the message "Not responding" and I have to restart to continue working (say that work this way, it becomes impossible).
I tried to reinstall but I have not solved, I have also the same problem even with Visual Studio 2015.
The strange thing is that this problem is only with my user account, and with the remote desktop, sessions instead works without problem.
What is the problem?Thanks a lot to all
This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)* -
