[USRP-users] Tx RF chain still on after transmission?

2021-11-03 Thread Chang, Kaixin
Dear all, I have a questuon regarding the TX chain. I wanna measure some data transmitted from TX antenna to Rx antenna and without any stop measure the noise. So for example I configure the program to send 1000samples and receive 1500samples (so 500 noise samples). My question is, when the tra
