- new OOT-blocks: phase_calc_ccf hier-block, measurement_sink_f
- new python submodules: flowgraphs, functions, rts_tests
- new apps: usrp_phasealignment.py - cmdline example for manual testing
OOT-Blocks:
- phase_calc_ccf takes two complex input streams and conjugate
multiplys them and extracts the phase from the result and converts
it to degree scale
- measurement_sink_f: takes a float input stream and calculates average and stddev for a
specified number of samples. Start of a measurement is invoked by a
call of start_run() on the block. After a couple of runs average and
stddev can be extracted.
Python modules:
- flowgrahps contains reconfigurable flowgraphs for different GNU
Radio RF test cases
- functions contains functions which are used in different apps/RTS
scripts
- rts_tests contains test cases which are meant to be executed from
the RTS system. Depends on TinyDB, labview_automation
Apps:
- usrp_phasealignment.py is an example how to use the underlying
flowgraph to measure phase differences. Commandline arguments of
uhd_app can be used and several additional arguments can/have to be
specified. Runs a phase difference measurement --runs number of times and averages
phase difference over --duration seconds. Between measurements USRP
sinks are retuned to random frequencies in daughterboard range.
Results are displayed using motherboard serial and daughterboard
serial
