489acc49a5 usrp/fft: one more analysis tool for antenna measurements
- usrp/fft.c: utility to read a set of samples obtained with
  usrp2_rx_cfile.py and to perform a Fourier transform on them
- usrp/Makefile: use LDLIBS for libraries, not LDFLAGS
- usrp/Makefile: added "fft"

417ef7b8c1 usrp/p: cleanup and more command-line control
- usrp/p.c (find_peak, main): moved data processing to separate function
- usrp/p.c (find_peak, usage, main): new option -s skip to set the number
  of samples to skip (default: 0)
- usrp/p.c (find_peak, usage, main): new option -d to dump the histogram
  instead of picking the peak
- usrp/p.c (find_peak, usage, main): the percentile can now be set on the
  command line (default: 0.9)

7f9488e156 The Great ATSPI Renaming, part 11: TODO update and fix script using a tool
- TODO: changed reference to atspi-txrx to atrf-txrx
- TODO: removed renaming from the list of pending issues
- usrp/step: atspi-txrx is now called atrf-txrx

fe7d55dc8b Small improvements to spectrum walk script.
- usrp/step: the default number of runs (10) can now be overridden on the
  command line
- usrp/step: usrp2_rx_cfile.py likes to busy loop from time to time. Add
  a CPU time limit to prevent this from getting out of hand.

dce0a19794 Measurement results and a script to view them.
- usrp/plot: convenience script to plot the signal strength scans
- usrp/step-A, usrp/step-I, usrp/step-II: signal strength scans for three
  boards

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"
