我们表征了一个50 GHz的梳状发生器与采样示波器。通过仔细控制输入功率、输入谐波和梳状发生器温度，我们测量的输出频谱的标准不确定度为0.1 dB和0.5度。我们校正测量的时基失真，阻抗失配，一个内联衰减器，和示波器的采样器的复频率响应。我们还报告的梳状发生器频谱的稳定性和记录的时间窗口，驱动水平，和温度的影响。这些结果为高速测量的实践者提供了一般指导，并为未来谐波相位基准校准的实验室间比较提供了基准。
We characterize a 50-GHz comb generator with a sampling oscilloscope. With careful control of the input power, input harmonics, and comb generator temperature, we measure the output spectrum with a standard uncertainty of 0.1 dB and 0.5 degrees. We correct the measurements for time-base distortion, impedance mismatch, an inline attenuator, and the complex frequency response of the oscilloscope's sampler. We also report on the stability of the comb-generator spectrum and the effects of the recorded time windows, drive levels, and temperature. These results provide general guidelines for practioners of high-speed measurements and a benchmark for future inter-laboratory comparisons of harmonic phase-reference calibrations.
