摘要
介绍了一套皮安级电流测量系统,系统以Keithley 6487B静电计作为主体,通过Labview编程实现对6487B的实时控制,测量系统的本底小于0.1 p A,可以很好的满足皮安级电流测量的要求,该系统成功的应用于直流X光机电缆辐照试验中,取得了理想的测量效果。
This paper Introduces a pieo - ampere level current measurement system, which can achieve real - time control of the Keithley 6487B via Labview programming. And the noise of the system is less than 0. lpA. So, this system can satisfy pico - ampere level current measurement requirements, and which has been applied to the DC X- ray machine experiments successfully.
