Try the code in gnuradio-examples/python/digital, and be sure to read the README. [EMAIL PROTECTED] digital]$ ./benchmark_tx.py --help Usage: benchmark_tx.py [options] Options: -h, --help show this help message and exit -m MODULATION, --modulation=MODULATION Select modulation from: cpm, d8psk, qam8, dbpsk, dqpsk, gmsk [default=gmsk] -s SIZE, --size=SIZE set packet size [default=1500] -M MEGABYTES, --megabytes=MEGABYTES set megabytes to transmit [default=1.0] --discontinuous enable discontinous transmission (bursts of 5 packets) --from-file=FROM_FILE use file for packet contents -f FREQ, --freq=FREQ set Tx and/or Rx frequency to FREQ [default=none] -r BITRATE, --bitrate=BITRATE specify bitrate. samples-per-symbol and interp/decim will be derived. -T TX_SUBDEV_SPEC, --tx-subdev-spec=TX_SUBDEV_SPEC select USRP Tx side A or B --tx-amplitude=AMPL set transmitter digital amplitude: 0 <= AMPL < 32768 [default=12000] -v, --verbose Expert: -S SAMPLES_PER_SYMBOL, --samples-per-symbol=SAMPLES_PER_SYMBOL set samples/symbol [default=none] --tx-freq=FREQ set transmit frequency to FREQ [default=none] -i INTERP, --interp=INTERP set fpga interpolation rate to INTERP [default=none] --log Log all parts of flow graph to file (CAUTION: lots of data) --use-whitener-offset make sequential packets use different whitening --excess-bw=EXCESS_BW set RRC excess bandwith factor [default=0.35] (PSK) --no-gray-code disable gray coding on modulated bits (PSK) --bt=BT set bandwidth-time product [default=0.35] (GMSK) -B FUSB_BLOCK_SIZE, --fusb-block-size=FUSB_BLOCK_SIZE specify fast usb block size [default=0] -N FUSB_NBLOCKS, --fusb-nblocks=FUSB_NBLOCKS specify number of fast usb blocks [default=0] _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
