Hi All,

As I understand it, the B210 has maximum master clock rate of 61.44[MHz]
for one channel, and 30.72 [MHz] per-channel while using two channels.

I am receiving through two channels, and would like to use a sample rate of
20[MHz] with central freq. of 98 [MHz]. I set the master frequency to max
by editing the following line in the python file:

*        self.uhd_usrp_source_0.set_clock_rate(30.72e6, uhd.ALL_MBOARDS)*

(Which is equivalent to writing "30.72e6" under "clock rate" in the
USRP-SOURCE block in the grc).

To my utmost disappointment, I receive the following error:

*[WARNING] [MULTI_USRP] The hardware does not support the requested RX
sample rate:*
*Target sample rate: 20.000000 MSps*
*Actual sample rate: 15.360000 MSps*

Why is the master clock rate only half of what I assigned it?
(I did try to insert anything above 30.72e6 and received an error that it
exceeds the limit)

Thanks for your time,
Steve.
