建立在扫频基础上的同轴反射测量和传输测量的精度直接取决于测量系统的元件所达到的宽频带匹配的程度。即使在窄带应用和单频率应用时,采用良好匹配的元件也可简化测量的步骤,并且有可能避免使用阻抗匹配调配器和复杂的误差修正。这里叙述的是一系列的同轴元件,包括功率分配器、衰减器、终端负载及八端口总和接头(eight port suming junc tion),其中等效集中参数电阻元件已经得到利用,已达到剩余驻波比在 The accuracy of coaxial reflection measurements and transmission measurements based on swept frequencies is directly dependent on the degree of broadband matching achieved by the components of the measurement system. Using well-matched components simplifies the measurement step even in narrow-band applications and single-frequency applications, and it is possible to avoid the use of impedance matching adapters and complex error correction. Described here are a series of coaxial components, including power dividers, attenuators, terminal loads, and eight port summing junctions, where equivalently concentrated parametric resistive components have been utilized and the remaining standing waves have been reached Than in
