Dear Anil,
the thing I've replied on usrp-users still applies here; I'll
include the original text, so that others don't take the time to
write the same:
Hi Anil,
You'll have to ask yourself: How does the time in your for loop
correspond to samples?
In a simulation (ie. signal source/sink, no hardware blocks), the
"wall clock time" has absolutely nothing to do with how fast
samples pass through your flow graph. In a flow graph with
hardware sinks, the wall clock time of your PC will very
loosely correspond to some sample time.
I've already hinted at the GNU Radio guided tutorials and the GR
mailing list. Right now, I'm explaining basic concepts together
with the quite advanced stuff you want to do; this won't work very
well for neither of us, so I'd ask you to really work through
tutorials 1-6, and things will be much clearer, making you able to
work much faster!
Best regards,
Marcus

Hello everyone,
I have got a serious problem while implementing
frequency hopping spread spectrum using USRP B210.I tried to
generate a python file using a GRC file containing a signal
source followed by a sink.Then I applied the logic for hopping
using a for loop.But there's no output visible on the gui. The
terminal shows the hops in frequency but the GUI doesn't and it
stops abruptly. So what should I do in order to solve the
problem. I need to show somehow the hops on the GUI in real time
.
Regards,
Anil
