Analyzing and Validating Experiments for the Performance of Small Space Electrostatic Discharge Test Device

To satisfy the demands of small space tests which are applied in electrostatic discharge(ESD) transient pulse field under nuclear radiation,an economical sensor based on active optical electric modulation method was designed and employed to build a fiber-optical electric field test device.Moreover,the sensor designing guideline was outlined,and some experiments for analyzing the performance of the test device were discussed in detail.Through experiments of frequency signal injection,square impulse injection and square impulse radiation,the response time and the linear degree of the proposed device were analyzed.Furthermore,the performances of the device were validated by means of ESD radiation.The experimental results show that the response time of the device is less than 1 ns,which is capable of ns level radiating field test,and the linear degree is well.The sensitivity can be adjusted by means of regulating the load capacitance of the receiving antenna.The proposed device can be utilized in time domain tests for ESD radiating field and in small space tests for ESD transient pulse field.
