I am using USRP 2955 R and I have connected an antenna to one end of a two channel splitter and connected the other two ports of the splitter to the two RX1 pors of USRP. I am getting different phase difference in each run of USRP though in one particular run the phase difference is constant for all channels. The tuned frequency is 2.4 GHz and sampling rate is 1 MSps so as expected that channel phase differences are almost same. But when I stop acquiring data and restart it using gnuradio or the API, then I am getting again a new value of phase difference across all channels, which is again same across channels. Is USRP so unstable that it gives different value of phase difference for each run for the same frequency, and sampling rate? The setup in the runs are also the same.
