Hi Martin,

These are the rates I need to able to change between: { "50.0" "25.0" "20.0" "10.0" "5.0" "2.5" "2.0" "1.0" "0.8" "0.5" "0.2" } MHz
It seems to work fine even tough i get the Error and I have no need to time align or sync the two RX channels.
But still I'm a bit worried about it and would like to get rid of it.

Regards Simon

From which rate to which new rate are you changing your sample rates?

Hi,

For several reasons I need to change the sample rate during runtime (i.e
flowgraph running) in my gnuradio program. I use Ettus X310 and receive
on two UBX-160 cards. The error that I get when I change the sample rate
is the following:

UHD Error:
    The receive packet handler failed to time-align packets.
    1002 received packets were processed by the handler.
    However, a timestamp match could not be determined.

Any ideas on how to address this?

Regards Simon
