I am doing some preliminary tests to check the behaviour of two USRPs. The setup is simply an USRP B210 connected via cable to a N310. The B210 is sending a constant 1 at 2,48 GHz, the N310 is just receiving and saving the data to a file, both USRPs operating at a sample rate of 25,6 MHz. As expected, one can see the carrier frequency offset due to the LO frequency offset between the two USRPs as a result. However, there are periodic "jumps" that shift the signal up and down for some time. I am mainly bothered by the fact that these jumps happen instantly between two singular samples. What kind of effect am I seeing here?
Thank you for your help, Michael
