Thanks much. That did produce a flatter top. Is there any way to terminate the output of the log 10 block before it goes to the scope input? I am searching for any such blocks in GRC but coming up with nothing.
What do you mean by "terminate the output"?? There's the null sink, if that's what you want.

The pulses that I get from the output of our receiver (as observed in a scope) seem to be of the same amplitude where as the pulses I observed coming out of the N200 (as observed in GnuRadio scope sink) seem to vary a lot. Attached are the plots and the grc flowgraph. I am wondering if there is anything else I should do (in the flowgraph) to get the pulses more smoother and somewhat of the same amplitude. Appreciate any response to this.

Over-the-air there will be small variations in the time domain, and that's exactly what your plot is showing. You could stick a log10 block in there to show on a log scale. That might produce a flatter "top". _______________________________________________ USRP-users mailing list [email protected] <mailto:[email protected]> http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
