Keysight Technologies Launches New N5511A Phase Noise Test System

Keysight Technologies introduced a new phase noise measurement system to optimize and prove performance of new designs and meet operational requirements. The N5511A Phase Noise Test System (PNTS) is the foundation of test setups that can measure down to kT (-177 dBm/Hz). The N5511A’s flexible architecture solves specific challenges faster, accepts any reference source that is electronically frequency tunable, and suppresses excess noise from the system itself or from reference sources and test accessories (amplifiers, attenuators etc.).

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.
