PROBLEM TO BE SOLVED: To shorten a time to measure a transmission signal of a CATV station, to unify measuring method and further, to make the unification and labor saving of data management possible. SOLUTION: A spectrum analyzer 13 and a computer 15 are connected, and the computer 15 automatically measures the frequency and level of a CATV channel which are preliminary set by the analyzer 13 that is controlled by the computer 15. In such cases, a transmission signal that is used by a CATV station can efficiently be measured by automatically correcting the loss part of a measuring cable through the computer. Also, by processing it in a file format, it is possible to unify measuring methods and further to permit the unification and manpower saving of data management. |
