FYI, the new git repo doesn't seem to have usrp2_siggen.py under gr-utils. usrp_siggen.py seems to work in the same way with minor differences but the naming makes it seem like it's for the original usrp. I probably wouldn't have thought it was compatible if I was just poking around for the first time.
