Abstract

The UK’s National Physical Laboratory has recently introduced a primary national standard system for S-parameter impedance measurement in the millimetre wave region. The system consists of a vector network analyser used in conjunction with a desktop PC. The PC runs in-house written software for VNA control, data collection and processing. The system is used to perform measurements in metallic waveguide sizes WG 23, WG 25, and WG 27, covering a frequency range from 33 GHz to 110 GHz. This paper describes the measurement system, the method of measurement and outlines the dominant uncertainty contributions along with typical measurement uncertainties obtained with the system.
