| Signal Generator Script 1.0 |
| =============================================================================== |
| This script takes command line arguments to broadcast the sum of various signals |
| with differing strengths. The script takes in arguments by specifying a type of |
| signal to broadcast followed by the corresponding parameters for that signal. |
| This script requires the user to specify at least 1 signal in order to operate. |
| In order to broadcast from file, use the '-f' flag and specify the path to the |
| file as well as a factor which corresponds to a db-gain on the specific signal. |
| A general db-gain can also be specified by using the '-g' flag to amplify the |
| combined signal. |
| |
| Options: |
| -h, --help Show this help message and exit |
| -f FILENAME,FACTOR, --file=FILENAME,FACTOR |
| Add signal from file (raw 64 bit complex) which can be |
| generated using the 'bandpass_recorder.py' script. The |
| raw file can be read using scipy.fromfile. |
| -u FREQUENCY, --frequency=FREQUENCY |
| Specify the desired frequency in KHz, defaults |
| to 2412KHz (Wifi Channel 1) |
| -g DB_GAIN, --gain=DB_GAIN |
| Specify the db-gain amplification, defaults to 50db |
| |
| Note: If you are playing from a file and are getting Underruns (U), try moving |
| the file to local storage. |
| |
| A set of useful recordings have been placed at "/google/data/rw/teams/gfiber/sdr/recordings" |
| that can be used for testing or other purposes. |
