What is an embedded signal in labview?

What I have to do is this:
I need to Generate 2 2D arrays and make a subvi (done) but I need to do this with an embedded signal (I don't know what this is at all)
Then I have to multiply the 2D arrays and display it on an intensity plot (easy)
My main issue comes with the topic of an embedded signal, I have absolutely no clue what this is.

Our Project is this:
Develop a program with the following Specifications:
The program mast contain:
Comments for each data and structures (10 points)
Use at least two vector, two arrays    (10 points)
Save and read from files                                                                        (10 points)
Graduate students only (search specific data in multiple files )    (10 points)
Use at least one SubVI. (10 points)
Perform at least two mathematical operation with matrices        (10 points)
Display intensity plots                                                                                 (10 points)
Graduate Students only (Show a 3D plot)                                      (10 points)
Use at least one local and one global variable    (10 points)

Want to input interference signal in labview + perform bandpass filtering/demodulation

Hello to whom it may concern,
I have a fiber-based OCT system linked to a Tektronix TDS 2024B digital oscilloscope, with which is showing the interference fringes of the low-coherence lightsource. The signal is linked to the computer using the NI DAQ Board USB-6251. I want to input the fringes using Labview and not only that, but to perform a high-pass filter command, along with an active full-wave rectifier and a lowpass filter to see the group velocity of the interference pulse. Now I am new to using Labview so this question be a little elementary, however I am struggling here. Any helps are greatly appreciated.

Hello!
Basically you will need to measure a signal in LabVIEW and then perform some processing on it. First I suggest, if you haven’t, getting familiar to LabVIEW and DAQmx that are basically what you will use for acquisition. For processing, you might find useful some toolkits we have for filters and signal processing. I’m linking information on these subjects, if you wish, you can download them in evaluation mode and take a look at the examples on how to use those functions.

Thanks smercurio the link appears to be broken so anyone who tries just remove the "." at the end.

Unfortunately, we were not able to migrate the polls and topics to the new system when we launched. The good news is that we still have access to the data and are investigating our migration options available.
We will also focus on getting some new topics and polls out to the community in the next few weeks.

What's it take to get LabView up and running?

Hello. I'm new to LabView and in the process of learning what I can about it by working through a couple of training books. Anyway, what do I need to get LabView 6.1 to control Agilent and Anritsu test equipment -- specifically voltage supplies, a network analyzer, and a spectrum analyzer. I presently have a GPIB card in the computer. Is any other hardware required to get this operational? Where do I find drivers? Thanks for any response.

Assuming you've got cables to connect your GPIB card to your instruments, I don't think you need any additional hardware in order to use LabVIEW to automate the control of the instruments.
I'll assume that your GPIB card is installed and functional if not, try its self-tests or go to http://www.ni.com/support/gpib/ for help.
To install LabVIEW instrument drivers for your instruments, go to http://ni.com/idnet and browse or search your way to the drivers you need. This will give you a suite of LabVIEW VIs to programmatically control your instruments from LabVIEW.
After you download and install the drivers (instruction links on the driver pages), you can get up to speed by examining the Application Example that will likely appear in the palettes for your i
nstruments. There's also a CD available of all of our instrument drivers; you can request one from your NI sales engineer.
As a final note, the LabVIEW Basics I training course (http://ni.com/training) does an excellent job of teaching this topic (the final day of the course) as well as teaching LabVIEW programming fundamentals.
Best of luck,

What are the limitations of using labview 8.5.1 developers suite verses a real-time module in field point applications?

What are the limitations of using labview 8.5.1 developers suite verses a real-time module in field point applications? Can an exe. be loaded onto a field point controller or does the controlling program have to reside on a PC for example?

centerbolt is correct, you can't load a .exe or even run a program on the fieldPoint controller unless you have the Real Time module. However, that does not mean you can't use your FieldPoint bank without the Real Time module.
From LabVIEW for windows you can make calls to the fieldpoint IO using the fieldpoint read/write functions.
This program runs on the PC not the FieldPoint controller. If you loose network connection to the fieldpoint, your program will loose connection to the IO. For many data logging applications this type of arrangement can work just fine. However, if this is the only type of application you are ever going to run, then you may as well not buy the Real Time controller for your fieldpoint but the network controller only.
If your application requires more reliability, and/or greater determinism than can be achieved by running a program on windows, then you should use the LabVIEW Real Time module and develop a program that can run down on the FieldPoint controller independent of windows.

What is the data throughput in labview. I want to use the parallel as acheap digital i/o to drive a stepper motor.

I am trying to use the parallel port on a win xp machine to send data a@ up to a 3k rate. This is for the the purpose of driving a stepper motor. I have tried the port.out vi and placed this vi in a loop and it on a scope it looks like I am limited to a a 200hz rate. What am I doing wrong??? Can labview do this or is it too slow ???
Thanks

Basically the way the Port I/O VIs are implemented they call through a
device driver for each port access. This slows down the maximum port
accesses to something like 1000 times per second depending on the speed
of your CPU.
There is a way to do it faster but that is a little more trick
y. The
idea is to use a device driver to enable particular port addresses to be
accessed directly from the application level instead of always going
through the kernel.
I have written such a VI library and accompagning DLL and device driver
and made it available on OpenG. It is not yet part of the standard
binary distribution packets so you will have to get it from the CVS
repository.
Go to:
http://cvs.sourceforge.net/viewcvs.py/opengtoolkit/portIO/built/portio/
and download all the files in there including the ones in the
subdirectory "ogportio.llb" and if you like "docs"
If you want the nitty gritty technical details you can also look at
http://cvs.sourceforge.net/viewcvs.py/*checkout*/opengtoolkit/portIO/c_source/Description.htm?rev=1.5
On my 866 MHz Pentium mobile I can increase the number of port accesses
in this way from 440 ms for 4000 read byte port accesses (100us ms per
access) to 20 ms for the same number of read accesses (5 us per access).

What are the advantages of using LabVIEW projects in TestStand, as apposed to just a path to a vi

What are the advantages of using LabVIEW projects in TestStand, as apposed to just a path to a vi ?
I am modifying an existing workspace for a new product, and it seems like more work to add the vi's into a LabVIEW project
does it gain anything in the long run

Hi Rusty,
I wanted to quickly clarify on the integration between TestStand and LabVIEW Projects.
As Jeff mentioned, some of the big benefits of using LabVIEW Projects is to organize code and to namespace them.
For instance if you had a project called "Power Supply" that housed all your power supply code and had a VI in that called "Initialize", and another project called "Temperature Chamber" that also had a VI called "Initialize", both these VIs are namespaced by the project, so there is no longer confusion about which "Initialize" VI is being used.
Now from a TestStand point of view, in prior version of TestStand, we lost some of this benefit because TestStand did not know about TestStand projects and called VIs simply as un-namespaced VIs. However, in TestStand 2010 (released last year, free eval available at ni.com/teststand), we added the ability to (optionally) call VIs within the context of their projects. This means that:
VIs are now namespaced by their project, even when called from TestStand
VIs can use project specific constructs like NI-DAQmx tasks and conditional compilation settings
Note: When creating deployments, the VIs maintain their projects and namespacing, so this benefit holds true for deployments as well.
Additionally, someone had mentioned looking into using lvlibs to namespace your VIs for deployment. Two comments:
With TestStand 2010, this is no longer neccessary since the project itself namespaces the VIs
You might also want to look into LabVIEW Packed Project Libraries, which combined several VIs into a single file. Think of it as a DLL specific to LabVIEW that is as easy to call as normal LabVIEW VIs. TestStand 2010 can call VIs that are exposed by PPLs. In addition, the deployment utility can automatically pack your VIs into PPLs for deployment.
Hope this is helpful!

If you already have IIS web server running, you need to run the LabVIEW web server on a different port to avoid conflicts. It probably won't start because the port 80 is already in use.
Check options.."Web Server: Configuration" within LabVIEW.

Hi,
Remember that when we are deploying a wireless setup we should always do a site survey to determine the amount of APs you need, power levels to use on each AP, where to locate each AP so that you can get the required mbps per client on each AP since as you know wireless is half duplex and also a shared medium.
Also depending on how god the signal quality is too each client they will get a required data rate.
There would not be a specific number since this will all depend on the amount of clients you need to support on the site and bandwidth per client.
Here is the link for the FAQ of a site survey.

what's the last version of labview to support classic FieldPoint?
Solved!
Go to Solution.

In general, yes. Others with more experience than I do might be able to help.
I think there is a chance you can get some older versions of LabVIEW to work on Win7. There are occasional message threads where people have asked about a particular version and others said they have been able to get them to work. Just that official support for older versions of LabVIEW for a Win7 OS has ended.
