摘要

本文介绍了如何校准示波器的相位响应，特别是在10mhz到1ghz的低频范围内。该方法采用三混频器法校准的标准混频器的相位响应作为参考相位。我们描述了基本原理，并展示了使用平衡混频器和实时示波器(1ghz BW)获得的结果。

Phase calibration of oscilloscopes at low frequencies

This paper describes how to calibrate phase response of oscilloscopes, especially at low frequencies from 10 MHz to 1 GHz. The method uses the phase response of a standard mixer calibrated by three-mixer method as the reference phase. We describe basic principles and show results obtained using a balanced mixer and a real-time oscilloscope (1 GHz BW).
