Example 1: 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](https://www.nuand.com/bladerf-1/). However, because
this package presents a common interface for all SDR devices, the same code can be used
to interface with additional supported radios.

Code
----

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

.. code-block:: python

    import time

    from ria_toolkit_oss.datatypes.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.
