The Source-Measure Unit can also test other diode parameters, including forward voltage drop and breakdown voltage.
源-测量单元还可以测量其它的二极管参数，包括正向电压降和击穿电压。

The SourceMeter instrument first performs the necessary DC tests, such as forward voltage, reverse breakdown voltage, and leakage current.
源表首先进行必要的直流测试，例如正向偏压、反向击穿电压和漏流。
