在高频电特性测试中，具有良好的测量稳定性和重复性是非常重要的。传统上，同轴连接器用于高质量和稳健的测量。质量合格的手持式探头经过验证并被广泛采用，以减少测量资源。然而，在循环研究中，不同用户的测量质量存在很大差异，这些差异可能由探头设计、接触质量、测量设置、工程师操作等因素造成。如何减少工程师操作对大批量测量的影响是至关重要的，特别是对于20 GHz以上的高频应用。因此，半自动化Delta-L解决方案被提出并开发用于PCB损耗表征，以提高测量稳定性并减少工程师操作引起的变化。
In high-frequency electrical characterization, it is very important to have good measurement stability and repeatability. Conventionally, co-axial connector is used for the high quality and robust measurement. Handheld probes with the accepted quality were validated and widely adopted to reduce the measurement resource. However, the measurement quality by different users are much different in the round robin study and these difference may cause by the probe design, contact quality, measurement setup, engineer operation and etc. How to reduce the measurement variation affected by engineer operation in high-volume measurement is critical, especially for over 20GHz high-frequency application. Therefore, semi-automation Delta-L solution was proposed and developed for PCB loss characterization to improve the measurement stability and reduce the variation caused by engineer operation.
