set_tx_center_freq expects a frequency in Hz.

Most of the python executables will accept a frequency expressed with
a trailing SI suffix.  E.g., 1800M 1.8G.

You can ask what the valid tuning range is using:

  double min = u2->tx_freq_min();
  double max = u2->tx_freq_max();

If you're using the usrp2, you may find it helpful to look at the
doxygen generated docs:
