This application note provides an overview of field testing radar systems and Line Replaceable Units (LRU) using high-performance FieldFox combination analyzers having multiple measurement modes including a peak power analyzer, vector network analyzer, spectrum analyzer and vector voltmeter. This application note will show several measurement examples of pulsed and secondary radar signals and also reviews the basics of monopulse radar.
Modern Vector Network Analyzer (VNA) architectures such as those based on Nonlinear Transmission Line (NLTL) samplers and distributed harmonic generators now offer a beneficial alternative to traditional sampling VNAs. They allow for a simplified architecture and also enable VNAs that are much more cost effective. It is shown that NLTL technology results in miniature VNA reflectometers that provide enhanced performance over broad frequency ranges, and reduced measurement complexity, providing VNA users a unique and compelling solution for their high-frequency measurement needs.

Read this application note for an overview of the key challenges in testing power amplifiers and front end modules with envelope tracking. Learn about how to reduce test cost, achieve fast throughput, and maintain high test quality using the modular Keysight M9381A PXIe VSG, and the M9391A or M9393A PXIe VSA, as well as how to perform high speed harmonic test using the M9393A PXIe VSA.
The theories and operations of intermodulation distortion (IMD) are well understood. It is one of the key metrics in categorizing the linearity of active and passive electronic components and devices. There are various instruments available from leading equipment manufacturers to perform IMD measurement in the RF and microwave region - two signal generators, a power combiner and a spectrum analyzer; a vector network analyzer with a signal generator and a power combiner. However, extending the IMD measurement to the millimeter wave and sub-millimeter wave frequency ranges is quite another matter.
A newly developed superconducting RF MEMS varactor provides additional capabilities for digital transmission, including tunable filters for improved signal selectivity and noise rejection. Development of the superconducting circuitry at cryogenic temperatures takes advantage of advanced probe station technology from Lake Shore.
Low noise amplifiers (LNAs) play a key role in radio receiver performance. The success of a receiver's design is measured in multiple dimensions: receiver sensitivity, selectivity, and proclivity to reception errors. The RF design engineer works to optimize receiver front-end performance with a special focus on the first active device. This paper considers device- and board-level variables that affect LNA performance and confront the engineer at each level of design in accommodating the various requirements of specific applications.
