Plot IQ signals from Airspy HF+ (2)

Now, trying to use PyQtGraph.

What is PyQtGraph?

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).

Plot IQ signals from Airspy HF+

Let’s see if I can receive the IQ signals correctly with my Python program.

A weak CW signal is fed into Airspy HF+.

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

There is a DC offset, but looks reasonable.
