Measuring method and measurement equipment null of unnecessary

摘要

PURPOSE:To achieve a higher reliability with a simple measurement while reducing measuring time, by moving an antenna at a low speed turning a device to be measured at a high speed with the functions of a measuring device held at a max. to measure unwanted electromagnetic wave. CONSTITUTION:First, the position of an antenna 5 is initialized to select a measuring band and a function of a measuring device 8 is set for the max. holding to start the turning of a turntable 4. Then, in the measurement, a jamming level is measured doing a frequency sweeping within a selected band. To achieve this max. holding function, the measuring device 8 is so set as to hold the max. of jamming level at several of frequency points each as preset within a measuring band selected. The antenna 5 is turned once in one direction at a low speed between upper and lower positions turning the turntable at a high speed 4 to complete a measurement per band.
