I've got a modification to scopesink.py, gr_trigger_mode.h, and
gr_oscope_guts.cc to allow viewing of an eye pattern. I added an "eye" trigger
mode selection to the trigger menu, and an eye trigger mode that triggers on
either a rising or falling edge (rather than only on one or the other). Wh
I've been looking at the bpsk.py code within the gmsk2 folder in
gnuradio-examples. I want to see what the complex signal looks like before and
after the gr_clock_recovery_mm_cc block. (On my version of a bpsk receiver,
I'm not able to get anything that makes sense to me out of the Mueller and
I forgot to modify the subject line. Oops.

Has anyone already created an eye pattern modification (e.g.
http://en.wikipedia.org/wiki/Eye_pattern) for scopesink.py?
For BPSK, it requires triggering on any rising or falling edge, resetting the
trigger after .75Tsymbol, making the horizontal axis match the width of
Tsymbol, and make the di
Thanks, that was indeed the problem!

Hello,
I am working on demodulating a BPSK signal (a manchester coded stream of
pseudorandom bits.) I'd like to use a gr_costas_loop_cc block to recover the
carrier. However, when I try to create the block with all five args (alpha,
beta, max_freq, min_freq, and ref_phase) as floats, python r
Hello,
I am using a FLEX900 daughterboard with the USRP board. I am trying to run
usrp_oscope.py, an example program contained within gnuradio-examples-0.7. I
have installed the latest usrp updates from

First, usrp_oscope would not run due to inco
