You can controll the analyzer as an application for Windows
And with the Anroid application
The setup process is very simple. In arduino nano you need upload a sketch
which controls the analyzer in it specified quartz frequency.
The device is power on by USB. The device is calibrated once without load,
and the second time with a load of 100 ohms. Now it can be used.
And now slides)))
