How To Generate And Measure Noise Power Ratio (NPR) Signals
By O.Gerlach and F.Schütze, Rohde & Schwarz GmbH & Co. KG
In order to generate noise power ratio stimulus signals and to measure the resulting noise power ratio of a device under test (DUT), Rohde & Schwarz offers the Noise Power Ratio (NPR) as an add-on tool for WinIQSIM / WinIQSIM2™ software. This NPR measurement technique drastically reduces measurement time compared to classic gain wobbling, and is able to characterize the linearity of a wideband amplifier over a custom frequency range. Download this application note for an overview of the software, its features, hardware and software requirements, installation, parameters, and more.
