+Align LOs in the front-end (SBX/WBX + N-Series)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Using timed commands, multiple frontends can be tuned at a specific time.
+This timed-tuning ensures that the phase offsets between VCO/PLL chains
+will remain constant after each re-tune. See notes below:
+
+* There is a random phase offset between any two frontends
+* This phase offset is different for different LO frequencies
+* This phase offset remains constant after retuning
+
+ * Due to divider, WBX phase offset will be randomly +/- 180 deg after re-tune
+
+* This phase offset will drift over time due to thermal and other characteristics
+* Periodic calibration will be necessary for phase-coherent applications
+
+Code snippet example, tuning with timed commands:
+::
+
+ //we will tune the frontends in 100ms from now
+ uhd::time_spec_t cmd_time = usrp->get_time_now() + uhd::time_spec_t(0.1);
+
+ //sets command time on all devices
+ //the next commands are all timed
+ usrp->set_command_time(cmd_time);
+
+ //tune channel 0 and channel 1
+ usrp->set_rx_freq(1.03e9, 0/*ch0*/);
+ usrp->set_rx_freq(1.03e9, 1/*ch1*/);
+
+ //end timed commands
+ usrp->set_clear_time();

After tuning the RF front-ends,
each local oscillator may have a random phase offset due to the dividers
