|
> Raw data recorder for RTL-SDR receivers.
|
|
> Data is encoded using I/Q sampling (aka quadrature sampling).
|
|
> More information: <https://osmocom.org/projects/rtl-sdr/wiki/Rtl-sdr>.
|
|
|
|
- Save RAW data from a frequency (specified in Hz) to a file:
|
|
|
|
`rtl_sdr -f {{100000000}} {{path/to/file}}`
|
|
|
|
- Pipe data to another program:
|
|
|
|
`rtl_sdr -f {{100000000}} - | {{aplay}}`
|
|
|
|
- Read a specified number of samples:
|
|
|
|
`rtl_sdr -f {{100000000}} -n {{20}} -`
|
|
|
|
- Specify the sample rate in Hz (ranges 225001-300000 and 900001-3200000):
|
|
|
|
`rtl_sdr -f {{100000000}} -s {{2400000}} -`
|
|
|
|
- Specify the device by its index:
|
|
|
|
`rtl_sdr -f {{100000000}} -d {{0}} -`
|
|
|
|
- Specify the gain:
|
|
|
|
`rtl_sdr -f {{100000000}} -g {{20}} -`
|
|
|
|
- Specify the output block size:
|
|
|
|
`rtl_sdr -f {{100000000}} -b {{9999999}} -`
|
|
|
|
- Use synchronous output:
|
|
|
|
`rtl_sdr -f {{100000000}} -S -`
