Traceable S-Parameter Measurements Up to 165 GHz Using 0.8 mm Coaxial Standards Open
To extend SI-traceable calibration for coaxial measurements up to 165 GHz, seven calculable offset short standards in the 0.8 mm coaxial system are used. The standards are calculated based on dimensional measurements and used for an overde…

Influence of LO cable movements on VNA measurements using Frequency Extensions Open
In this study, the impact of local oscillator cable movements or drift during VNA measurements using frequency extenders is investigated. A non-reciprocal measurement error caused by alterations of the local oscillator signal in R 900 (WR …

Uncertainties of S-Parameter Measurements in Rectangular Waveguides at PTB Open
In this work the determination of measurement uncertainties in scattering parameter measurements for waveguide interfaces ranging from R 100 (WR 90) to R 2.6k (WR 3, WM-864) is presented. For each waveguide band a Thru Reflect Line calibra…

Connector effects and reference plane influence in the N-Type connector Open
In this paper we outline the impact of mixing slotted N-type and slotless N-type connectors during a vector network analyzer calibration. We want to point out that making precise measurements of typical transfer standards, while using both…

Comparison of <i>S</i>-Parameter Measurement Methods for Adapters Open
In this work two methods for the characterization of adapters meaning reciprocal two-ports with different connector styles on both ports are analyzed and compared in detail. The focus is on the comparison of these approaches in terms of re…
