Is it possible to make a Frequency Domain Reflectometer using LabView? For waveguide frequency measurement?

Hi everyone
I have a tricky question that I have looking around for the answer but couldn't find it!
I want to know if I can build a Frequency Domain Reflectometer (FDR) to measure frequency return in waveguide. Telecommunication engineers would understand what I mean! It a bit like TDRs but its frequency instead of time. 
I would like to build a Frequency Domain Reflectometer using labview application, how can I do that? What sort of code do I need and what equipment do I need to operate with the NI code?
Please give me the chance to thank you all very very much for your help and support and for looking here,
regards
Fezz

Hi Fezz,
I am not familiar with using FDR systems but know there is a good example of producing a TDR in LabVIEW available on the community. This might provide you with a base and a grasp of the architecture you could use to create the functionality.

Regarding the equipment you would require to achieve this I strongly recommend contacting your local NI office who will be able to adviser you fully as this will depend upon your desired specification.

  • How to make a multimeter in multisim using LabVIEW

    Hello there, I want to make a multimeter in Multisim using LabVIEW. And I have read this article http://zone.ni.com/devzone/cda/tut/p/id/5635#toc3 before.
    And now I have these questions:
    1. How to measure a resistor? The Impedometer.llb in lvinstruments folder made me confusing.
    2.how to measure the current? I can measure the voltage but I dont know how to measure the current.
    3.What's the meaning of "instrument version" in every _multisimInformation.vi, whether I can modify it?

    Hello,
    A question for you: your multimeter will acquire real data (using a data acquisition board) ? or, is it just for simulation (like the Multimeter included in Multisim)?
    The Impedometer.llb is a library that contains all the files for the Impedance Meter instrument in Multisim. As stated in the template, the instrument version constant is an internal reference that must not be modified.

  • Is it Possible to make a Tuesday as a due day for payment. in terms of payment obb8

    Hi Gurus
    I need to make terms of payment 28 days from the base line date of posting date. and payment should made on every Tuesday once the invoice is due after 28th day.
    Is it possible to make Tuesday is the base for Payment. instead of Date e.g instead of 2nd payment i need to make payment on every Tuesday.
    Thanks in advance
    Ravi

    Hi Ravi
    In SD and MM you can do it with BADI or enhancements. Please, see these notes:
    Note 1156325 - BAdIs in the Logistics Invoice Verification environment
    Note 301077 - User exits for the interface to accounting
    For invoices in FI (FB60/FB70 and so on), maybe with the BTE 00001610
    I hope this helps you

  • Possible to make Phone Vibrate twice in a row for a text

    I been wondering lately if there is a way to make your Iphone vibrate twice for a text. I know after a few mins it will vibrate again but a lot of the time i never even feel it cause the Iphone vibrate is so weak compared to most phones. So from what i know you can not do this, but maybe in the future they could provide this option. Would be a great little upgrade that would matter a lot to me and possibly to many other people. Cause i know that if im wearing jeans or moving around chances are i wont feel it unless i have sound turned on and i cant always have that.

    You can submit feedback to Apple: http://www.apple.com/feedback/iphone.html.

  • Is it possible to preset to JPEG High when using 'Save for Web...'?

    Hi,
    I am using photoshop elements 10. When I am ready to save an image under 'SAVE FOR WEB..' can I preset it to 'JPEG HIGH' cos right now it will pop up 'GIF'.
    When I am using PSE2, I am able to launch it as JPEG HIGH. Now, I have to click on the popdown menu to select 'JPEG High'.

    You need to right-click on the PSE desktop icon and choose "Run as Administrator".
    Then, open a file in PSE, use Save for Web and change all the settings to what you prefer. Hold down the Alt key and the "Done" button will change to a "Remember" button. Click it and then save your image. The settings will be saved and you do not have to run PSE as an administrator again.

  • Can you make a fully automated Action using Save for Web? - Illustrator CC

    I have been trying to create a simple action using the Save for Web feature. When I run the created action it stops on the Save to Web window until I click on "Save" then it brings up the finder window asking me to select where to save it and I then have to click "Save" At that point the Action continues to run and completes.
    I'm using this process to export JPEGs of client labels for an web based government submission. The guidelines are pretty tight and the Save for Web gives me the best results for File Size, Image Size, and Quality... basically the files have to be small, but legible. Our files are organized in a Client/Project/SKU structure so batch processing with the Export command is not really an option.
    I have created many actions & batches over the years, but never had this kind of issue with such a simple action. Is there a way to bypass these prompt similarly to what a batch would do?

    I would love to know the answer to this as well. I am having the exact same issue. Super annoying

  • Is it possible to develope an applicatio​n in Atmel AT91SAM926​3 using Labview

    Hi friends,
     I have exp in labview automation but totally new in Embedded applications . I have one Atmel AT91SAM9263 EK (including touch screen disply) borad with m. is it possible to develop applications using labview. for this purpose which module we required. From where i can start. please help me for that.
    thanks,
    niks

    You have multiple options:
    Since, it is supported by Keil (Atmel AT91SAM9263) you can follow the LabVIEW for ARM Microcontrollers porting guide (http://zone.ni.com/devzone/cda/tut/p/id/6994). You may be especially interested how Phytec board has been ported.
    Also, if you want other RTOS, you can use Microprocessor SDK and read again about Phytec (http://digital.ni.com/manuals.nsf/websearch/AB597F​3FD5D9011886257448005F4A0C).
    Eiso-risky:
    Even if you posted two times, I shouldn't click the button because this is a ARM926EJ-S and not Cortex-M3.
    Would it were a Stellaris or SAM3U ..., but where is such a button?

  • Is it possible to publish to personal domain name and publish blog to .mac?

    I just finished publishing my website to a personal domain via iweb and .mac. Now I want to create a blog to post to .mac. Is this possible or will it automatically publish to my personal domain? I really don't want to mix business (website) with pleasure (blog). Thanks to all who post.

    Create a separate site and put the blog page in it. You can make it easy to make two separate domain files, one for each site, and manage them with iWebSites or Multisite for iWeb. That will keep your personal site separate form your business one. Each will have a separate URL. The personal one will be http://web.mac.com/your .Mac account name/the site name/the site name.html (or index.html).
    I use iWebSites to manage multiple sites.. It lets me create multiple sites and multiple domain files.
    This lets me edit several sites and only republish the one I want.

  • Valid Frequency Domain Analysis ?

    There seems to be two issues with using the MyDAC for frequency domain analysis ( Bode Plots etc. )
    1) The system does not employ  Anti-Aliasing Filters . This can create major frequency fold-back problems.
    2) The analog inputs are multiplexed which leads to a channel to channel phase error .. up to 180 degrees at the Nyquist frequency.
    Is there any 'behind the scenes' processing done to mitigate these issues ??
    Thanks in advance
    Solved!
    Go to Solution.

    Hello ProfP,
    Thanks for the post! Sorry to leave you hanging for so long. I have some answers for the 2 points you asked about above.
    1. You are correct, the myDAQ system does not employ Anti-Aliasing Filters. The ELVISmx Bode Analyzer artificially limits the input frequency when using the myDAQ to 20 kHz. At that frequency, you
    only get 10 points per period from both the AO and AI. 
    Anti-alias filters behind the multiplexer would slow down settling behavior, so they were not included. You can add filters in front of the multiplexers (at the AI0 and AI1 pins). I'd recommend they be buffered, though. Charge injection on the multiplexer makes high speed scanning very sensitive to source impedance. Note the effect in the Settling Time versus Different Source Impedance figures (21 and 22) of the myDAQ manual: http://www.ni.com/pdf/manuals/373060b.pdf 
    2. You are correct. Two-channel acquisitions are phase-skewed by the 1/(2*scan rate) when the scan speed is faster than 40 kSps/ch. For example, if you acquire at 200 kSps/ch, the interval between consecutive measurements on AI0 and AI1 is 1/(2 * 200 kHz) = 2.5 us. Below 40 kSps/ch, the phase skew is constant at 12.5 us. This is intended to help very slow acquisition rates appear more like simultaneous acquisitions rather than keeping 180 degree phase skew unnecessarily. These are default configurations. You can adjust the conversion interval parameter through the DAQmx API if you prefer to customize the behavior.
    Let us know if this is the information that you needed and thanks for using NI myDAQ!
    Cheers

  • Octave analysis of frequency domain data in SVT

    Hello!
    How can I make the octave analysis of frequency domain data in Sound & Vibration Toolkit?
    Thanks,
    Alfrednovi

    Hi!
    To make the octave analysis of frequency domain data you have to pass in your time domain data to the Octave Analysis VIs. The time domain data will allow you to window the signal using the correct values.
    The Sound and Vibration toolkit has several examples that show how to do this. You can find them under Help>>Find Examples and then browsing to Toolkits and Modules>>Sound and Vibration. This directory has Traditional DAQ and NI-DAQmx examples as well as Octave and Third Octave analysis.
    You can also look for other examples using the Example Code Library.
    Good Luck,

  • UFF in frequency domain

    Hello,
    I'm new in Labview. I'm trying to extract data from a Frequency Response Function to a UFF file. I know there is an example in the "Sound and Vibration toolkit" but is to extrat data from time waveforms in the Time Domain, but I wanted to extract data from the Frequency Domain.
    Could anyone help me?
    Thanks,

    Hi, I have been reading this post It is very interesting and also I
    need help. I am doing a project involving scattering matrix (S

    use of S parameter in frequency domain from Vector Network Analyzer, I
    need to convert S parameters from frequency domain (sweep from 8.2 GHz
    to 12.4 GHz) to time domain using inverse chirp z transform or any. I
    have no idea how to implement it. Could you please help or guide me how
    to implement them. I am using Labview 8.0 and matlab. Please see the attached file for the data in frequency domain both linear , dB magnitude and phase.

  • Image Watermarking in Frequency Domain

    I am working on a Project which aims at studying the digital watermarking on image, with both spatial domain and frequency domain.
    I have finished the spatial domain but is frustrated with the frequency domain right now. I have no idea on how I can possess the frequency domain of a image. Is there a built-in function which can help us to do so?
    Thank you for your help.

    i have no clue what a frequence domain is, but with logical thinking I can quickly rule out that such an API will exist in core Java. Java was not built to contain standard solutions for every exotic business requirement out there. It contains the basic functionality to work with images only, the rest is up to you.
    However, you could direct a google search towards a third party API that might deal with your problem domain. One possible search area is Java Advanced Imaging, which contains complex image processing functionality.

  • Frequency domain analysis

    Does photoshop offer frequency domain analysis of an image?
    The standard way to remove noise, i.e. background spots, is do spectrum analysis and remove those high-frenquency signal. Is photoshop image-> adjustment -> level a frequency analysis?

    NR not very trivial. IMO anyway.
    I had much the same questions when I moved from frequency domain to time domain. A strong preparation in analog engineering treated time domain sparsely, particularly noise. We dealt with detector noise in a nuclear physics lab by running the detectors in pairs at cryogenic temps. The detectors were connected to a coincidence circuit (and gate to you digital folks!). Even then, the output of the gate had to be carefully amplified, then subjected to an A to D converter where the output was displayed as a histogram. I'm sure things have progressed mightily since then, (ca 1950's).
    I used the coincidence idea back about 2004 or so when I needed an image absolutely as noise free as possible by shooting the object (an exposed wooden frame for a building constructed from Port Orford Cedar.) twice, then constructing a curve applied to each image to allow adding them together to match the colors and values of a single shot.  Extended versions of PS now allows this without any curve inventions!
