See the documentation here: https://files.ettus.com/manual/structuhd_1_1stream__cmd__t.html On Wed, Aug 7, 2019 at 7:15 AM Cherif Diouf via USRP-users <usrp-users@lists.ettus.com<mailto:usrp-users@lists.ettus.com>> wrote: Hello guys, I have developed a custom RFNoC CE connected to one radio core of the X310. The core will act as receiver and provide samples to my CE for further processing (Antennas-> RX frontend + noc_radio_core -> custom CE). However, I would like the radio core to start sampling and providing data only after a deterministic and fixed duration t0 consistent with the 5ns time counter and likely synchronized to an external PPS used as time reference. From python, I know I can use the "set_time_next_pps" call to initialize the USRP X310 time. But how to tell the radio core to stay in a idle state until the time keeper matches my duration t0? Can it be done by software? Or the only option is to use CHDR packets and VITA timing?
