Re: Valve Problem

I tried with throotle block before Valve but same thing happens, flow
graph seems to stop working. I think the problem is with Probe Avf Mag^2
block because when i removed this block the valve start working. Now a
new thing happens, whenever I make it open using a variable during
execution, the scope stops but when I re-enable (close) the valve again
an error occurs that is,

usrp2::rx_samples() failed
usrp2: channel 0 not receiving

THere is one more problem when i try to run any flow graph in 64-bit
machine. When I enable “Realtime Scheduling” to ON or when I try to
change USRP2 source frequency or decimation value during execution
(using a variable) the error occurs

Failed to enable Realtime Scheduling
