Until now, large scale testing of device linearity has been both time-consuming and prone to measurement errors. An automated system is described which measures Nth order intermodulation products of devices operating in the 1-18 GHz range. Measurement time is significantly reduced and both accuracy and repeatability improved.","PeriodicalId":101637,"journal":{"name":"25th ARFTG Conference Digest","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133550507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NASA has an ongoing program to develop the new technologies required to meet the demands of future systems. Under this program, higher frequency components and more efficient system techniques are being developed and tested.
