Eric,
Whe I try to run a recent version of usrp_siggen.py from CVS on Mac OS X,
it produces the requested output signal for just a second or so, then exits.
I see in the source code, at the end of main:
try:
fg.start()
except KeyboardInterrupt:
pass
fg.stop()
As I understand it, this code executes fg.start(), which returns
almost immediately, and then executes fg.stop(), and then exits from main.
On my system, the code does not wait in fg.start() for a keyboard interrupt.
For now, in my working version I've changed the end of main back to:
fg.start ()
raw_input ('Press Enter to quit: ')
fg.stop()
That works as it should - usrp_siggen keeps running until I type ^C.
