开放式同轴线和计算机控制的网络分析仪已被广泛用于在无线电和微波频率下测量活体组织的介电常数。分析了网络分析仪的校准误差和随机误差引起的测量误差[1]、[2]。系统的不确定度为= 0.05 dB和= 0.3°。关键词-射频，微波介电常数，自动网络分析仪。
An open-ended coaxial line and a computer-controlled network analyzer have been extensively used for measuring the tissue permittivity in vivo at radio and microwave frequencies. An analysis is presented of measurement errors resulting from calibration and random errors of the network analyzer [1],[2]. The uncertainties in our system are ¿¿ = 0.05 dB and ¿¿ = 0.3°. Key Words-Radio frequency, Microwave permittivity in vivo, Automated network analyzer.
