Embodiment Construction

[0012] The embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, which consists of three parts: a transient strong electromagnetic pulse test probe, a transient strong electromagnetic pulse test host and a digital storage oscilloscope. The transient strong electromagnetic pulse test probe includes a shielded antenna 1 and a fully shielded probe box 3. The antenna is a monopole antenna with a shield 2 on the periphery and has no directionality. It can be changed by adjusting the length of the exposed shield. The measurement range of the test instrument; the fully shielded probe box is equipped with an impedance conversion circuit, a follower circuit and an electro-optical conversion circuit, and the signal of the antenna is input to the impedance conversion circuit through the interface J2 and the capacitor C1. The impedance conversion circuit includes a field effect transistor Q1 (BFR30), a high-frequency transistor Q2 (...
