CalPod更正持续时间

这取决于两件事：1）用于初始化calpod的原始校准的时间。
如果初始化时IFBW为低电平，或者通道平均值设置为1以上，则会影响时间。
2）在calpod控制中使用的OSL平均值。
您可以判断所需的平均值，但我的指导原则是：a）如果从测试端口到坐标元件的损耗小于10 dB，则不需要平均b）如果损耗是10-16 dB，并且
频率低于18 GHz，无需平均;
如果频率高于18 GHz，则使用2个平均值c）如果损耗大于16，则使用低于18 GHz的2个平均值，高于4个平均值。
d）如果损耗大于约20 dB，则需要单独调查获得良好结果所需的内容。

  This depends upon 2 things:

1) the time of the original calibration used for the initialization of the calpod.  If the IFBW is low at this initialization, or channel averaging is set above 1, it will affect the time.
2) the OSL averaging used in the calpod control.  You can be the judge of the averaging needed but my guideline would be:
          a) if the loss from the test port to the calpod is less than 10 dB, no averaging is needed
          b) if the loss is from 10-16 dB, and the frequency is below 18 GHz, no averaging is needed; if the freq is above 18 GHz, use 2 averages
          c) if the loss is greater than 16, use 2 averages below 18 GHz, 4 averages above.
          d) if the loss is greater than about 20 dB, you need to individually investigate what is needed to get good results.
