Vector-Network-Analyzer Calibrations
نویسنده
چکیده
We develop an uncertainty analysis that captures the dominant sources of measurement error in state-of-the-art WM-380 (WR 1.5) rectangular-waveguide vector-network-analyzer measurements over the frequency range 500–750 GHz. We use the analysis to assess thru-reflect-line, thru-short-match, and thru-short-radiating-open calibrations. The comparison shows that thru-short-match and thru-short-radiating-open calibrations outperform thru-reflect-line calibrations, and that this is true even when multiple lines and optimal averaging are used to improve the thru-reflect-line calibrations.

A low-cost and portable vector network analyzer (VNA) which covered operating frequency between 1MHz to 3GHz is used for vector reflection coefficient and standing wave ratio (swr) of the various microstrip antennas. This paper presents measurements of various ultra wideband (uwb) microstrip antennas for applications in biomedical field. Selection of antenna is an important key for detection of...
متن کاملNew theoretical analysis of the LRRM calibration technique for vector network analyzers
In this paper, a new theoretical analysis of the fourstandards line-reflect-reflect-match (LRRM) vector network-analyzer (VNA) calibration technique is presented. As a result, it is shown that the reference-impedance (to which the LRRM calibration is referred) cannot generally be defined whenever nonideal standards are used. Based on this consideration, a new algorithm to determine the on-wafer...
متن کاملA Unified Approach for Reformulations of LRM/LRMM/LRRM Calibration Algorithms Based on the T-Matrix Representation
This paper investigates a unified theory to derive vector network analyzer calibration algorithms based on the T-matrix representation, by which means the line-reflect-match (LRM), line-reflect-match-match (LRMM), and the line-reflect-reflect-match (LRRM) calibrations are formulated. The proposed calibration theory is more general than other versions of LRM, LRMM, and LRRM in that an arbitrary ...
متن کاملCalibration of a Measurement System for High Frequency Nonlinear Devices
The research work described in the thesis is situated in a broad technological context. It is explained what vectorial “nonlinear network” analyzers are and why they are needed. The importance of traceable calibrations is highlighted, in general as well as applied to the vectorial “nonlinear network” analyzer.
