What type connectors should the line standards have? What are the advantages of using two lines instead of one line and a through connection when test port imperfections are considered? How many lines are optimum from a quality control point of view? What should the lengths be? The answers to these questions appear to be: ¿ The quality of the line is much more important than that of the test port. A perfect line will calibrate out most imperfections in the test port. An example is given where 75-¿ test ports are calibrated with 50-¿ lines, and then used to measure reflection coefficient relative to 50 ¿ with very little error. ¿ Greatest accuracy is achieved with line standards having male connectors. ¿ Two lines get rid of many test port imperfections that one line cannot. Three lines will show up a problem if one line is bad. Five lines will identify which line is bad. Five is probably optimum. ¿ There may not be an optimum for the actual lengths of a set of lines, but there does appear to be an optimum difference in the lengths.","PeriodicalId":287736,"journal":{"name":"29th ARFTG Conference Digest","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126531153","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}

The method applies the phase discriminator error model described in an eariler paper (\"Coherent I/Q Detector Performance Under Extended Drive Signal Conditions\", 27th IEEE ARFTG, June, 1985) in such a way as to account for discriminator and system signal sampling channel phase and attenuation imbalance. The calibration results refer I & Q measurements directly to the device under test (DUT) input and output ports. The method accounts for discrimiator error as a function of device gain. The calibrated system is effective over 18 dB of dynamnic device gain with no phase ambiguity. Phase and gain accuracy is better than 1 degree and .1 dB respectively. For calibration reference, the system utilizes two standard step attenuators and a bi-phase modulator precalibrated on an Automatic Network Analyzer under continuous wave conditions. These devices provide known gain and phase conditions referenced to the DUT ports. The method and hardware yield a simple and cost effective way to generate accurate, repeatable pulsed RF phase and gain measurements.","PeriodicalId":287736,"journal":{"name":"29th ARFTG Conference Digest","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131607585","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}
