Hi, Some of our USRPs are using UHD 3.10 because they are in old systems. and I am also using UHD 4.1.0 in some other USRPs in new system. The USRP products are all NI USRP 2944 (X310).In my applications, I need to use PPS signal to synchronize multiple USRPs. After applying PPS signals, I read back the time in USRPs one by one. Because of network delay, there is some difference between the readings. However, the difference is much bigger in UHD 4.1.0. The interval between two USRPs using UHD 3.10 is about 0.2ms while it is about 1.4ms in UHD 4.1.0 Does this mean that UHD 4.1.0 is slower than UHD 3.10? Thanks for any suggestion, Hongwei
