Re: USRP2 1pps synchronization delay

GNU Radio
1

I’m seeing the same order of values as Cliff is. The delays specified
in the
link that you posted Josh are too small - the delta is that I’m not
using UHD
(I’m strictly using gnuradio 3.3.0).

The link you posted Josh mentioned that the delays could be calculated.
Is
there a formula readily available? Otherwise, I’ll try to figure it out
myself.

Also, I’m noticing that my sync_and_start_rx_streaming_at command
hangs about
15 out of 16 tries (the other 1 of 16 times or so everything works) - I
didn’t
know if others are seeing this too. Maybe I’m restarting it too fast in
succession? I’ve noticed sometimes I’ve had better luck waiting a minute
or so
between restarts.

Thanks,
David

I asked about problems with sync_and_start_rx_streaming_at in
No data from start_rx_streaming_at, sync_and_start_rx_streaming_at - GNU Radio - Ruby-Forum. Your symptom sounds a little
different, though.

I’ve since moved on to UHD and had better results.
