**2. Overview of the experimental device**

**Photo 1:** Experimental device.

**Computer**: for control, acquisition, and data processing;

**NLTL**: electrical nonlinear transmission line;

**HS3–100**: which accommodates the arbitrary signal generator and digital oscilloscope;

**GPS-3030d**: generator of analog tension to polarize the line;

**Voltmeter**: for the control of the tension of polarization of the line;

**Amperemeter**: for the control of the current, which crosses the line.
