Save Power Spectrum from ni5660

[Om]

I am using ni5660 to capture the power pectrum using "ni5660 Power in Band" example.

Is it possible to save the power spectrum for later use?  In which format can it be saved?  Is there a VI that will do it for me?

When I mean the spectrun data I mean the output of "ni5660 Read Averaged Power Spectrum".

Thanks.

Hi,

Using any of the File I/O VIs within LabVIEW should work fine for this.  I have attached an example of how this could be implemented by writing to a binary file.  When streaming data in the way you intend to with this example, the binary file format is recommended because it is more efficient in terms of space than other file formats.  In addition to the modified example I have also attached a sample VI that shows how you can read back the data written to the file and confirm that the spectrum actually was saved.  Let me know if you have any questions.

Hi 

i have a similar question to this, it is possible to save power spectrum cluster as a tdsm file. is there any way to covert  the cluster to an array

Hi philip_97,

Hi,

DO u know how to overlay power spectrum graph over each other as it is generated  in order to have all power spectrum graphs on one graph

Hi Philip,

create an array of plots for your graph…

(You don't have "several graphs in graph", you can have "multiple plots per graph"!)
