Werner Almesberger e445fe1b01 usrp/: a set of utilities for testing board performance with an USRP2
- usrp/d.c: reduce the number of data points in a file produced by
  usrp2_rx_cfile.py and print them as text suitable for gnuplot
- usrp/p.c: determine the peak amplitude in a series of transmissions,
  filtering noise and artefacts at the beginning of the data file
- usrp/step: step through all channels and measure TX power (for antenna
  tuning)
- usrp/Makefile: built "p" and "d"
