Practical Test & Measurement: Attenuators for Measurement

In this article for audioXpress, Jonathan Novick explains why the use of external attenuators are an effective and cost-effective way to measure signals above the maximum input voltage of an audio analyzer. Novick explains why there needs to be some consideration of the topologies and different attributes offered by such components for audio noise measurements. He compares the impact different attenuators’ thermal noise will have on measurements of distortion. This article was originally published in audioXpress, March 2019.
