Dear gr / USRP fellows, I'm currently experimenting with USRP B100 Local Oscillator relocation time. I've done some experiments on the RX path by tuning towards and away from an OFDM beacon signal.
I have flushed into the received signal some recognizable "relocation marks" which allowed me to analyze the received signal integrity in the temporal vicinity of the relocation instant. It looks like the LO responds to the steering command in some milliseconds to about two tens of millisecs, still "artifacts" such as unsuppressed, dominant carrier or unstable gain remain there for some hundreds of millisecs. I saw that the wiki states "perhaps a second" as the LO settling time. But can anybody confirm the above behaviour analysis ? best regards vince -- Vincenzo Pellegrini http://www.youtube.com/user/wwvince1
