In this design , the calibration and the test is done by switching the test channel . in the trl calibration , for solving the problem that one set calibration kit is not enough for three ports ’ connection , a new calibration step is added 在多端口测量系统的校准中,为解决trl校准件只有一套不够三个测试端口连接的问题,增加了校准步骤,使得只用一套校准件就能校准多端口系统而校准效果却维持不变。
