Re: [Discuss-gnuradio] Timestamping baseband samples

Hi Marcus, If USRP crystal has a ppm of +-25ppm, then its RF deviation, and the baseband decoder detects this drift and correct it by resampling till it gets the required number of samples. So my question is this input side drift is corrected by baseband synchronization, and this should not be

Hi Brandon, As this isn't really a GNU Radio question, I'm including the usrp-users mailing list; if you could follow up there (you'll need to sign up first[1]), that would help us keep the lists clean :) So, there's a lot of things that might or might not be right here; I'm picking my "most

Hi ben, the Ettus USRP series of devices (N2x0, B2xx, E3xx, X3xx, N3xx) have RX sample time stamping that you can find as tags in your sample flow. That means they can annotate a sample buffer with the device time of the first contained sample. The device time can be set according to an external
