Hi Marcus,
Thanks for your attention.
I have upload a bigger size image below. the x axis is sampling point which
reflects time and the y axis is margin which reflects the power.
I plot the image from the rx block of the gen2_reader project. The signal is
transmitted by the tx block of gen2_reader

Dear All,
my device: USRP N200
System: Ubuntu 13.04
1. I always get this on first connections (the next ones are okay):
$ uhd_usrp_probe

Go google information on how to disable Ubuntu from automatically managing
