实验先进超导托卡马克（EAST）上安装了一套基于电压和电流探头的新型测量系统，安装在匹配系统和离子回旋加速器频率范围天线之间的传输线上，以测量天线输入阻抗。这些数据可用于阻抗匹配点优化，以及通过从天线输入阻抗推导天线耦合电阻来评估耦合系数。幅度和相位差的测量误差对耦合电阻有明显的影响。一般来说，幅度测量误差对耦合电阻影响较小，而相位测量误差对耦合电阻影响较大。可以从功率测量中提取相位，而不是使用相位检测器。这样，根据电压探头的幅值、电流探头的幅值以及天线馈电功率就可以推导出天线的输入阻抗和耦合电阻。在之前的实验中，采用基于电压探针阵列的阻抗测量技术来评估耦合电阻。在EAST 2016活动中，对使用这两种技术计算出的负载耦合电阻进行了检测，结果一致。
A new set of measurement system on the Experimental Advanced Superconducting Tokamak (EAST), based on voltage and current probes, is installed on transmission line between matching system and ion cyclotron range of frequencies antenna to measure the antenna input impedance. The data can be used for impedance-matching points optimizing, as well as coupling coefficient assessment by deducing the antenna coupling resistance from antenna input impedance. The measurement error of amplitude and phase difference show distinct impact on the coupling resistance. Generally, the amplitude measurement error has a small impact on coupling resistance, while the phase measurement error significantly affects the coupling resistance. Instead of using phase detectors, phases can be extract from the power measurements. Thus, the antenna input impedance and coupling resistance can be deduced from the amplitude of voltage probe, amplitude of current probe, as well as the antenna feeding power. on previous experiments, the impedance measurement technique based on voltage probes array is utilized to evaluate coupling resistances. In EAST 2016 campaign, the load coupling resistance calculated by using such two techniques were detected and the results showed agreement.
