摘要

我们提出了一种改进高插入损耗测量的方法，该方法使用校准的矢量网络分析仪(VNA)，只需要两个额外的硬件。通过使用放大器和衰减器，测量波参数而不是散射参数，我们能够增加测量的动态范围，同时减少由VNA的本底噪声引起的不确定性。我们将我们的技术结果与标准方法进行了比较，插入损耗值高达110 dB。

A method for improving high-insertion-loss measurements with a vector network analyzer

We present a method for improving high-insertion-loss measurements with a calibrated vector network analyzer (VNA) requiring only two additional pieces of hardware. By utilizing an amplifier and an attenuator, and measuring wave-parameters rather than scattering-parameters, we are able to increase the dynamic range of our measurements while decreasing uncertainties due to the noise floor of the VNA. We compare the results of our technique to standard methods for insertion-loss values up to 110 dB.
