描述目前的低水平的设备需要的知识,技能,及正确的测试设备。即使使用所有三种,实现在低精度目前的水平可能是一个挑战,因为当前的水平往往是位于或低于测试设置的噪音水平。若要确保成功的低级当前的度量单位,这是重要的是要知道测试设备的类型对使用、 不同来源的测量误差和相应的尽量减少这些错误的技术。例如,检查测试的几个例子,碳纳米管场效应晶体管 (FET) 表征可以在学习过程中的帮助。 Optimizing Low-Current Measurements and Instruments

Characterizing devices at low current levels requires knowledge, skill, and
the right test equipment. Even with all three, achieving accuracy at low
current levels can be a challenge because the level of the current is often
at or below the noise level of the test se
