今、PyQtGraphを使おうとしています。

PyQtGraphとは何か？

PyQtGraph is a graphics and user interface library for Python that provides functionality commonly required in engineering and science applications. Its primary goals are 1) to provide fast, interactive graphics for displaying data (plots, video, etc.) and 2) to provide tools to aid in rapid application development (for example, property trees such as used in Qt Designer).

私のPythonプログラムで、IQ信号を正常に受け取れるか試して見ましょう。

弱いCW信号を、Airspy HF+に与えます。

user1@Asrock ~ % airspyhf_rx -z -d -r stdout -f 7.025 -m on > iq.bin
user1@Asrock ~ % python3 airspyhf.py

DCオフセットがありますが、良さそうに見えます。
