Background technology
It is coupled to check test specimen to bear with test specimen about the ability of the pulse signal on cable, work needs
Simulated field cable is exposed in rising edge or trailing edge pulse electromagnetic field quickly, the sensitive situations of detection test specimen.Army of state
Mark GJB151B-2013 " military equipment and subsystem Electromagnetic Launching and sensitivity require and measure " is corresponding is made that CS115 cable
The requirement of bundle injected pulse excitation conducted susceptibility test.To the waveform of required analog pulse signal, frequency, amplitude in standard
It is made that etc. index and is distinctly claimed.
At present highpowerpulse signal generate mainly by by energy in the time, be spatially compressed, to realize existing
High-peak power output is obtained in very short time.After the pulse signal source realized in this way is once shaped, parameter is non-adjustable,
And it is the most of a relatively high to realize cost.
