From 76e9e6393fe1d5a0ccc9e05deb431694921850ec Mon Sep 17 00:00:00 2001 From: Andrej Rode Date: Mon, 24 Oct 2016 10:25:42 -0700 Subject: gr-usrptest: Initial creation - 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 --- tools/gr-usrptest/lib/qa_usrptest.h | 38 +++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 tools/gr-usrptest/lib/qa_usrptest.h (limited to 'tools/gr-usrptest/lib/qa_usrptest.h') diff --git a/tools/gr-usrptest/lib/qa_usrptest.h b/tools/gr-usrptest/lib/qa_usrptest.h new file mode 100644 index 000000000..94ce3f33b --- /dev/null +++ b/tools/gr-usrptest/lib/qa_usrptest.h @@ -0,0 +1,38 @@ +/* -*- c++ -*- */ +/* + * Copyright 2012 Free Software Foundation, Inc. + * + * This file is part of GNU Radio + * + * GNU Radio is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 3, or (at your option) + * any later version. + * + * GNU Radio is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
