Testing advanced radars often demands exceptional performance from measurement equipment. The RSA6100A Series sets a new industry standard for advanced radar testing, delivering performance and innovative features that greatly simplify diagnostic troubleshooting and production test. Covering the popular radar bands through 14 GHz, the RSA6100A leads the industry with up to 110 MHz of instantaneous IF bandwidth and a minimum of 73 dB of dynamic range. Combining this raw hardware performance with innovative features like live DPX displays and Pulse Measurement Suite makes the RSA6100A an excellent choice for testing advanced radars. In this application note we explore the performance and features of the RSA6100A Series of Real-Time Spectrum Analyzers (RTSA) as applied to advanced radar testing.
