For those interested in a comparison of the measurement uncertainties between vector network analyzers (VNA) and time domain reflectometers (TDR), W. L. Gore & Associates has prepared a white paper in which they reveal the results of their study. While both instruments are able to analyze time or frequency domain data to accelerate product development cycles, Gore designed an experiment in which to determine if both instruments possess similar levels of measurement precision. The white paper is available for free download from the Gore web site, and Gore representatives will be at booth 731 at IMS 2010 all day to discuss the findings.
