Wideband and Narrowband Detection for Pulsed-RF Component Testing

Application Notes

Introduction

Vector network analyzers are the primary tool for accurate characterization of RF and microwave components, providing precision measurements of both magnitude and phase responses. For many devices, a continuous-wave (CW) stimulus/response coniguration is suficient.

However, many RF and microwave ampliiers used in commercial and aerospace/defense applications require testing using a pulsed-RF stimulus. This application note focuses on new pulsed-RF Sparameter measurement techniques and capability provided by Keysight Technologies, Inc. PNA Series of microwave vector network analyzers. This application note discusses the advantages and disadvantages of the two detection techniques commonly used (wideband and narrowband detection), and compares and contrasts the PNA series network analyzers (including the PNA-L) with the former industry standard for pulsed S-parameter measurements, the 85108A pulsed RF-network analyzer system.
