[Discuss-gnuradio] available sample rates for USRP2

[Kyle Zhou]

When I use uhd_fft.py –s 8M –f ….

It reported that

UHD Warning:

    The hardware does not support the requested RX sample rate:

    Target sample rate: 8.000000 MSps

    Actual sample rate: 7.692308 MSps

 

I am wondering how the actual rate 7.692308M is determined?

Is there any formula that I can use to ascertain that a given sample rate is available on USRP2?

Thanks
