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

Hi everyone Smiley Happy


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,

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.

Hi Aaron

thanks very much for your help. i relise it is kind of the same consept and background as TDR and FDR are in simular operations however i just wanted to get more info and share others view to see if i am on the right tracks. however your advice has trully supported me and i think i have a better view of what i need to do next. thank you
