Alexander,

The hard-coded magic numbers below the assert need to be corrected to
to be a function of the clock rate.  You're not seeing the problem
because of the daughterboard you're using, but if you're using a Basic
Tx, they come into play.

The existing magic numbers are particular percentages of 128e6.
The replacements, f(clock_rate), should be the same percentages.
They control when and which "coarse modulator" is used in the AD9862.

Can you please submit a slightly bigger patch?

I apologize for not writing earlier about what the problem was.

Thanks,
Eric
