相对于静止空气测试箱,伺服控制风洞提供了一个强制对流、均匀一致的测试环境。在测试对气流比较敏感的器件时，我们能够更加准确地测量出器件在不同风速下的热阻。4、Rjc测试夹具（风冷型）风冷型Rjc测试夹具是一个高性能的风冷型热沉，可以很方便地固定被测器件，是测量JEDEC标准定义Rjc的理想夹具。Rjc测试夹具采用了一种特殊的装置可以准确的测量壳温。5、Rjc测试夹具（水冷型）水冷型Rjc测试夹具需要配合循环冷水机使用，具有散热迅速的特点，通常用来测试IGBT和MOSFET等功率较大的器件。6、Rjb测试夹具完全按照JEDECJESD51-8的要求设计，用来测试结到电路板的热阻。

当被测LED的正向压降高于5V,可以选择LED高压放大器，提供28V的测试电压。8、功率放大器提供高达200A，400A和1000A的加热电流。9、热阻分析仪校准仪
