receive FM spectrum with USRP 2920

[Aristocrate]

Hello,

I am trying to monitor the whole FM Band (88 - 108MHz). I actually use the USRP 2920 as SDR to capture the HF signal. However, I don't know how to properly set the niUSRPvi for this purpose. Attached is the block diagram of my application.

thanks

Well you should be able to get the bandwidth.  The question comes down to can you fit it all across your eithernet port?

What errors are you seeing when you run your code?

Hallo Jeff-P-Bohrer,

I think, I can sent to host computer across ethernet cable. First of all, it is a 1Gbits link, second the USRP process up to 20MS/s. However the band I wish to monitor is also 20MHz wide which is the maximum Bandwidth of Low pass filter.

My VI actually generate no Error. But the plot seems no displaying the frequency range 88 - 108MHz.

My question : Do my block diagramm needs rewriting for the USRP  to receive spectral representation of the whole band?

Thanks

Its impossible to say without seeing some data.

Sure, I did it! I received data with up to 680MB/s.  The sulution to my Question was just setting IQ rate = Bandwidth.  The center frequency being the carrier frequency, LabVIEW can  receive up to 20MHz signal Bandwidth from USRP and store them provided you have an (rescent) HDD Drive installed and enough RAM. I implemented the producer/ consumer architectur for this endeavor.
