本文对超高频或微波频段双通道外差法相移测量系统中的交义耦合误差和寄生调制误差作了理论分析,并讨论了它们之间在各种不同情况下的正确合成规律。
In this paper, the theoretical analysis of the transconductance error and the parasitic modulation error in the UHVDC or microwave frequency bandpass heterodyne phase-shift measurement system are discussed. The proper synthesis between them is discussed in different situations.
