Parasitic Probe Effects in Measurements of Coplanar Waveguides with Narrow Ground Width

Gia Ngoc Phung & Uwe Arz
On-wafer measurements contain a large variety of parasitic effects degrading the accuracy of multiline Thru-Reflect Line (mTRL) calibration. These effects are caused by internal and external disturbances such as probe effects, multimode propagation, crosstalk between adjacent structures and radiation effects. While a lot of investigations have been performed for the most common coplanar waveguides (CPW) with nominal ground width, CPW with too narrow ground width have not been investigated thoroughly. This paper demonstrates how the...

Calibración estática de instalaciones de calibración para llaves dinamométricas : Directriz DKD-R 10-8

Braunschweig Physikalisch-Technische Bundesanstalt
En este documento, las instalaciones de calibración para llaves dinamométricas se denominan también dispositivos de calibración de llaves dinamométricas (o brevemente dispositivo de calibración). Esta directriz se aplica para calibrar instalaciones de calibración para llaves dinamométricas mediante llaves de transferencia de par de torsión sirviendo como patrones de transferencia y respalda los requisitos correspondientes de la norma DIN EN ISO 6789. Se describe un procedimiento para determinar la incertidumbre relativa de estos dispositivos. Esta directriz...

Calibration and verification of the torque measuring device of torsion testing machines : Guideline DKD-R 9-1

This guideline is applicable to the static calibration and verification of torsion testing machines using a procedure based on the calibration of materials testing machines according to DIN EN ISO 7500-1. The verification implies a general inspection of the torsion testing machine, including the parts used for the application of torque; a calibration of the torque measuring device of the torsion testing machine and a confirmation that the determined properties of the torsion testing machine...
