Detailed description of the invention
As it is shown in figure 1, this utility model includes interference source analog controlling unit, high-voltage amplifier and high-voltage discharging electrode,
The low-voltage output of interference source analog controlling unit is connected with the input of high-voltage amplifier, and the outfan of high-voltage amplifier is with high
The input of pressure sparking electrode is connected, and interference source analog controlling unit is used for producing low-voltage control signal, is simultaneously used for setting
Putting the parameter of low-voltage control signal, such as amplitude, frequency and persistent period etc., high-voltage amplifier is for controlling single to interference source simulation
The low-voltage control signal that unit produces is amplified, and high-voltage discharging electrode is used for carrying out electrion, so that superfrequency office is put demarcation
System is disturbed.
Interference source analog controlling unit includes signal source and signal controller, the outfan of signal source and signal controller
Input is connected, and signal controller includes controller and display screen, display screen is provided with and arranges key, start key and stop key,
Signal source is used for producing low-voltage control signal, and signal controller is for arranging the parameter of low-voltage control signal, including amplitude, frequency
And the persistent period, it being additionally provided with timer in signal controller, timer electrically connects with signal controller.
High-voltage amplifier uses 0-10kV high-voltage amplifier, for the low voltage control to the output of interference source analog controlling unit
