Yes, the final sampling rate of DAC is 128Msps which is fixed number.
But what is the default value for interpolation rate? As we know,
bitrate=128M/interpolation rate/samples per symbol* bit per symbol,
while bit per symbol could be known from modulation scheme, how to
calculate interpolation rate once the bitrate is set? Thanks!

Thank you, Brian!
Now i know how the interpolation changes, but if bitrate were set, how are
interp/decim rate and
samples-per-symbol derived respectively? Is there a default value for
interpolation rate? Thanks!!!
I believe the USRP operates at 128Msps for the TX DAC. This value
does not change.
