Abstract (in Japanese) (See Japanese page) 
(in English) S parameters of high frequency circuits are measured by a network analyzer. Calibration is performed before measurement using the network analyzer in order to remove influences of secular change, temperature, moisture, etc. in the internal circuit and connected cables. Reference planes are determined by calibration. S parameters are calculated using waves passing through the reference planes. There are several methods in calibration such as the method using Open/Short/Load(Match)/Thru, which is referred to as SOLT or TOSM, the method using Thru/Reflect/Line, which is referred to as TRL, and the method called electronic calibration (ECal) which does not require replacement of calibration kits. Sometimes ripples are observed in S parameters of simple circuit although the influence of internal circuit and cables are removed by calibration. The cause of ripples is difficult to identify. A consideration on the cause of ripples will be presented and discussed.
