From version 3 transmission or signal generation is supported for BladeRF and HackRF (since version 3.1) using a sample sink plugin. These plugins are:
- [BladeRF output plugin](https://github.com/f4exb/sdrangel/tree/dev/plugins/samplesink/bladerfoutput) Linux only
- [HackRF output plugin](https://github.com/f4exb/sdrangel/tree/dev/plugins/samplesink/hackrfoutput) Linux only
- [BladeRF output plugin](https://github.com/f4exb/sdrangel/tree/dev/plugins/samplesink/bladerfoutput)
- [HackRF output plugin](https://github.com/f4exb/sdrangel/tree/dev/plugins/samplesink/hackrfoutput)
- [File output or file sink plugin](https://github.com/f4exb/sdrangel/tree/dev/plugins/samplesink/filesink)
Transmision with "real" devices (BladeRF and HackRF) is supported in Linux versions only. Be also aware that this is **very experimental**. Code is not very efficient so you may experience **performance problems**. Contributions are welcome to enhance the transmission side.

The baseband stream is interpolated by this value before being sent to the BladeRF device. Possible values are:
- **1**: no interpolation
- **2**: multiply sample rate by 2
- **2**: multiply baseband stream sample rate by 2
- **4**: multiply baseband stream sample rate by 4
- **8**: multiply baseband stream sample rate by 8
- **16**: multiply baseband stream sample rate by 16
- **32**: multiply baseband stream sample rate by 32
Larger values introduce performance problems.
Be aware that the main samples buffer is based on the final sample rate so the larger the integration factor the larger will be the delay introduced by this buffer.
