LRR

SEMINAR ON LRR : LRR - LINE REFLECTS-account is a new self-calibration calibration procedure of vector network analyzers (VNA). AVI measure the complex transmission and reflection characteristics microwave devices. Analyzers must be calibrated so that eliminate systematic errors of measurement results. LRR calibration circuits are partly composed of known standards where L is a line item and is a symmetric R reflection standard. The calibration circuits are all the same mechanical length. The obstruction is a symmetric network on three mutual consecutive positions. The network consists of reflections that can indicates the transmission. Calibration of the structures can be easily reached as etched structures in microstrip technology. During calibration [G] [H], which represents the systematic errors in the AVI is removed to determine the unknown line barrier parameters.
