Hi, I am using mixed types of USRPs in my applications, namely, X310 and N310. The signals are timed. I find 0.2-second time difference between these two USRPs.Details:Each USRP is controlled by a Linux server; The same Linux version in all PCs;All USRPs are connected to the same Octoclock; UHD version is 4.1.0 in Linux servers;All Linux servers are connected to a control PC which is the client;The sampling rates are different: 184.32MHz in X310 USRP and 245.76MHz in N310 USRP Control PC sends command to set time 0 after PPS in all USRPs, then query the time in each of them.The time difference between USRPs of the same type is small, ~2ms, but the time difference between different types of USRP is much bigger, ~0.2s.Times should be impacted by sampling rate; when setting timers, no signal is transmitted. 2ms time difference between USRPs could be due to network delay; 200ms can't be because of network. It seems to be due to HW in USRPs. Does this mean that X310 and N310 are not synchronized? Thanks for any comment, Hongwei
