Embodiment Construction

[0017] Below in conjunction with accompanying drawing of description, the present invention will be further described.

[0018] according to figure 1 , a vibrator replacement structure for a pulse field strength probe, comprising an antenna receiving rod 1, an antenna base 3, and a PCB circuit board 4, characterized in that the antenna receiving rod and the antenna base are detachably connected, and the antenna base and the PCB circuit board Detachable connection, the PCB circuit board is located in the metal shielding shell 6, the antenna base and the antenna receiving rod are vertically arranged, and the PCB circuit board and the antenna base are perpendicular to each other. The length of the antenna receiving rod can be adjusted.

[0019] The load resistance and capacitance of the PCB circuit board are respectively the equivalent input resistance and input capacitance of the field effect transistor.

[0020] The antenna receiving rod passes through the surface of the meta...

Abstract

The invention relates to an oscillator replacing structure, in particular to an oscillator replacing structure of a pulse field strength probe. The oscillator replacing structure comprises an antenna receiving rod, an antenna pedestal and a PCB, and is characterized in that the antenna receiving rod is detachably connected with the antenna pedestal, the antenna pedestal is detachably connected with the PCB, the PCB is arranged in a metal shielding shell, the antenna pedestal and the antenna receiving rod are vertically arranged, and the PCB is vertical to the antenna pedestal. Compared with the prior art, the oscillator replacing structure has the beneficial effects that: the antenna receiving rod is detachably connected with the antenna pedestal, and the antenna pedestal is detachably connected with the PCB, thus the replacement of a rod antenna is facilitated, length of the antenna receiving rod is adjustable, and the antenna performance can be adjusted flexibly.

Description

technical field [0001] The invention relates to a vibrator replacement structure, in particular to a vibrator replacement structure of a pulse field strength probe. Background technique [0002] The existing transient electromagnetic environment measurement antenna in the laboratory consists of two parts: the rod part and the circuit part. The circuit part is mainly composed of a field effect tube amplifier, a small signal radio frequency amplifier and a photoelectric conversion part composed of a laser diode and a photodiode. There are some problems in the antenna that need to be further studied and improved: 1) The connection method of the rod antenna part to the PCB board is currently soldered, which is not conducive to the replacement of the rod antenna, and the performance of the antenna cannot be adjusted; 2) The circuit part The part of the voltage dividing capacitor cannot be adjusted, and the low frequency performance of the antenna is limited.
