2021-11-04 Thread Carey, Samuel Craig via USRP-users
Howdy, I'm trying to verify whether an E310 is synchronizing its clock based on a PPS input signal. I tried running the test_pps_input UHD example with -source option set to "gpsdo", "external", and the default. Even after I had disconnected the PPS input and GPS input, this test reported "SUCC
