Qpsk in python
WebThe code below assumes you have the Pluto’s Python API installed. This code initializes the Pluto, sets the sample rate to 1 MHz, sets the center frequency to 100 MHz, and sets the gain to 70 dB with automatic gain control turned off. Note it usually doesn’t matter the order in which you set the center frequency, gain, and sample rate.
