Time Domain Measurement System

Abstract

The report describes investigations and modifications, both in hardware and software, to improve the accuracy of an AFAL time domain metrology system for measuring the constitutive properties of materials. Experiments revealed that the systematic error observed in the data was due to small mismatches in the connectors adjacent to the material sample. The reflections and the systematic error were reduced by improving the design of one of the connectors and replacing the other delay line and connector by precision air line. Software procedures to further remove the effects of line mismatches from the data were also developed.
