 I just got usrp_oscope.py working with my new usrp. It took a bit of work 
getting past the "import Numeric", but once I figured out it really was 
Numeric, not numarrays, and found the rpm file through python.org, things 
went a bit more smoothly.

 I can input from a signal generator a sine (cosine?) wave from a low of 10kHz 
to a max of a couple Mhz and amplitudes from 40mv to almost 4volts.

 The usrp_scope.py software is a bit fragile and likes to seg fault when the 
trigger input, pos/neg or %value trigger are changed, but once I stopped 
pushing those buttons, things worked just fine.

 The same usrp_oscope.py file will load firmware.ihx and usrp_fpga.rbf from a 
usrp that is just powered up, then plugged into the USB2.0 (getting one of 
those helped a lot), and then just running usrp_oscope.py and nothing else.
