在本文中，我们提出了第一个出版的商业谐波相位标准（HPS）的重复性研究测量的非线性矢量网络分析仪。具体来说，我们测量两个谐波相位标准，其中一个是指定为20 GHz，另一个为50 GHz。通过进行5次校准，并在每次校准时从600 MHz到19.8 GHz进行100次测量，我们确定了复波变量矢量的重复性界限以及每个谐波分量的相关相位和幅度。我们还将平均相位值与制造商提供的相位值进行比较。虽然我们实现了标准的不确定性不大于0.73/spl度/，我们发现显着的变化，平均值与不断变化的HPS条件，并显示出大量的热贡献的证据。
In this paper, we present the first published repeatability study of commercial harmonic phase standards (HPS) measured by a nonlinear vector network analyzer. Specifically, we measure two harmonic phase standards, one of which is specified to 20 GHz and the other to 50 GHz. By performing 5 calibrations and making 100 measurements from 600 MHz to 19.8 GHz at each calibration, we determine the repeatability bounds for the complex wave-variable vectors and associated phases and magnitudes of each harmonic component. We also compare the mean phase values to those supplied by the manufacturer. While we achieve standard uncertainties of no greater than 0.73/spl deg/, we find significant variations in the mean values with changing HPS conditions and show evidence of a substantial thermal contribution.
