Amplitude phase graph

[Zosky]

Hello experts,

      I have some questions about getting the graph of amplitude and phase.

      As attachment, fig 1 is my vi, I use 'extract single tone information' to get the phase, and I get fig 2. This is not right one I need, so is there any other vi can get the phase? Thank you very much.

I don't have labVIEW at the moment in my PC but I think you have some VI's related to this phase magnitude's in signal processing pallet. Go to signal processing--> waveform measurements--> here may you can find what you want.

Hi ,

In block diagram, in search palettes type phase.you will fing many functions which gives phase.

Thank you very much, I will try to find another one, hope it can work.

Thank you vey much to answer my question. Actually, I have use the search function, but I can not find the useful one.  I want to find a vi which after reveiving the signal it can output the the amplitude and phase.

Hey Zosky,

Have you tried the "Tone Measurements" Express VI? It's located in the Functions palette under Express -> Signal Analysis. You should be able to output amplitude & phase as numeric or graph indicators.

Let me know if this helps.
