Hi!
I'm a newbie to gnuradio, and am designing a simple radiometer with an Ettus USRP x300 SDR, which has a board mounted GPSDO (and antenna, of course). What I want now is to get the (GPS) timestamp(s) of my data stream, so that I can match datapoints to correspondig UTC (gps)time. So what I have done is I've set "Mbx Time Source" in the USRP Source Block to "O/B GPSDO". I understand that I'm missing a step, possibly in the File Meta Sink block, so gps time is included in the data stream and contained in the data header (possibly in "rx_time")? Btw, what exactly is this rx_time (only info I've found is "format from UHD")? Is it expressed in days, hours? Referred to what date? Thanks in advance! /Manuel -- Mag.
