NPR – Noise Power Ratio Signal Generation and Measurement

  • Author: O. Gerlach
Noise Power Ratio (NPR) is an add-on tool for WinIQSIM / WinIQSIM2™ to generate noise power ratio stimulus signals and measure the resulting noise power ratio of a device under test (DUT) using Rohde & Schwarz instruments via IEEE or LAN interface. The Noise Power Ratio measurement technique can characterize the linearity of a wide band amplifier over a custom frequency range. Since NPR drastically reduces measurement time compared to classic gain wobbling, it is particularly interesting for production specific applications.
