SDR Reception

Introduction

The following examples demonstrate how to initialize an SDR, record a signal, and transmit a custom waveform. These examples assume familiarity with Python and SDR concepts.

In this example, we use the bladeRF. However, because this package presents a common interface for all SDR devices, the same code can be used to interface with additional supported radios.

Note

Most SDR devices require additional setup after installing RIA Toolkit OSS. See the SDR Guides for device-specific configuration instructions.

Code

In this example, we initialize the Blade SDR and configure it to record a signal for a specified duration.

import time

from ria_toolkit_oss.data.recording import Recording
from ria_toolkit_oss.sdr.blade import Blade

my_radio = Blade()
print(my_radio)
print(type(my_radio))

my_radio.init_rx(
    sample_rate=1e6,
    center_frequency=2.44e9,
    gain=50,
    channel=0,
)

rx_time = 0.01
start = time.time()
my_rec = my_radio.record(rx_time=rx_time)
end = time.time()

print(f"Total time: {end - start} seconds")
print(f"Length of the recording: {len(my_rec)} samples")

Conclusion

This example demonstrates how to use the Blade class to receive samples into a Recording object. By customizing the parameters, we can adapt this example to various signal processing and SDR tasks.
