Well, for one, 60Khz isn't a proper divisor of the 128MHz sample rate of
the DAC, which means it can't be properly interpolated.
The minimum sample rate that you can deliver to the USRP-E100 is
128MHz/512 = 250kHz, so you'll have to interpolate your
data stream up to 250kHz prior to "presentation" to the UHD sink block.
