ERROR CORRECTED IMPEDANCE MEASUREMENTS WITH A NETWORK ANALYZER

This paper presents a new class of self-calibration procedures for the error-correction of network analyzer measurements. The ZU, YU, ZUU, a nd the YUU self-calibration procedures only need one known and one or two unknown impedances for the calibration process. The ZY, ZYU, ZZU, and YYU calibration techniques provide calibration measurements with t wo impedance standards with known resistances and unknown reactances. The very good performance of the ZZU impedance calibration procedure i s demonstrated by experimental results up to 20 GHz. Measurements of s eries resistors verify this new calibration procedure and the measurem ents of capacitors connected to ground in two different mounting style s show the efficiency of the impedance calibration procedures.
