We have two daughterboards XCVR2450.
One of them is rev. 272 and the other is rev. 273.
By using a USRP2 with the daughterboard rev.272, the function
“self.u.set_center_freq” works correctly.
If we replace the daughterboard rev.272 with the second one (namely the
rev.273) the same operation fails (it returns NONE) at any frequency.
We are using a USRP2 with updated firmware (shipped with gnuradio r10633
on 2009-03-18) and FPGA (downloaded on 2009-03-18).
Is this an indication that our second daughterboard (rev.273) is
What’s the difference between the two revisions?
Thanks in advance,
