本工作旨在开发一种低成本的测量系统，用于检测食品中的盐分和糖含量。采用Mini-Circuits ZX 95 -2800+压控振荡器（VCO）、Mini-Circuits ZGDC 10 - 362 HP+高功率定向耦合器、Mini-Circuits PWR-6 GHS + USB智能功率传感器和由半刚性同轴电缆RG 402/U制成的开放式同轴探头。这项工作的主要思想是基于电磁反射由于阻抗失配。为了验证该检测系统的效率和准确性，与P系列网络分析仪（PNA）的测量结果进行了比较。讨论了Agilent 85052 D高温探头、RG 405/U和RG 402/U开放式同轴探头在所研制系统中测量反射系数的结果。索引术语-盐度;糖;开口同轴探头;反射系数;微波检测系统
This work is proposed to develop a low cost measurement system to check the salinity and sugar content of food. A Mini-Circuits ZX95-2800+ voltage controlled oscillator (VCO), Mini-Circuits ZGDC10-362HP+ high power directional coupler, Mini Circuits PWR-6GHS+ USB Smart power sensor and open-ended coaxial probe made of semi-rigid coaxial cable RG402/U are used. The main idea for this work is based on electromagnetic reflection due to the impedance mismatch. In order to verify efficiency and accuracy of this developed detection system, comparison with measured result from P-series network analyzer (PNA) is conducted. The measured reflection coefficient from developed system was discussed among Agilent 85052D High-Temperature probe, RG405/U and RG402/U openended coaxial probe.
