Peak and Mean Power measurements on wideband FMCW radar signal
Modern automotive radar systems occupy very wide bandwidth in order to have a good location resolution. In most cases the bandwidth is a result of frequency modulation or fast frequency hopping techniques, in some cases also pulse modulation is used. Besides the measurement of the frequency variation over time like deviation and linearity, the verification of emissions according to EN or FCC standards is mandatory. ETSI regulations for measuring peak transmission power from radar operating at 77-81 GHz require 50 MHz resolution bandwidth for the measurements. Publications are available that describe the measurements on pulsed UWB or MB-OFDM signals in detail, for frequency-modulated signals the information is limited.This application note provides information how to perform spectral emission measurements on frequency modulated CW signals with spectrum analyzers using RBW filters with very wide bandwidth, and explains the capabilities and the limiting factors of the Rohde & Schwarz FSW signal and spectrum analyzer to perform this measurement.

Introduction to MIMO
Modern radio communication systems have to provide higher and higher data rates. As conventional methods like using more bandwidth or higher order modulation types are limited, new methods of using the transmission channel have to be used. Multiple antenna systems (Multiple Input, Multiple Output – MIMO) gives a significant enhancement to data rate and channel capacity. This application note gives an introduction to basic MIMO concepts and terminology and explains how MIMO is implemented in different radio communications standards.

用于 50 GHz 以上相位噪声测试的测量装置
随着近来半导体技术的增强，50 GHz 以上的微波频率范围越来越具有吸引力，尤其是对 802.11ad、微波链路或汽车电子雷达等宽带通信应用而言。为确保这些应用正常工作，低相位噪声是一个重要因素。这需要准确测量相位噪声以增强性能。但是，这些频率范围内的测试装置存在挑战，特别是需要利用两个接收路径的互相关以抑制本振或混频器增加的相位噪声。两个外部谐波混频器结合商用相位噪声测试仪可用于分析相位噪声。理论上而言，此装置可以测量频率高达 500 GHz 的信号源。

Network Analysis Video Tutorials
Welcome to this introductory video show about the R&S® ZVA family of network analyzers. Network analysis is sometimes considered to be cumbersome and difficult to understand, a very offputting reputation for newcomers to network analyzers. To help you look at network analyzers in a different light, we have created this video series. We have intentionally refrained from explaining any theory in depth. Rather, we want to show you how to operate our analyzers for simple and useful applications. As well as just watching this video show, you can also use it as a guide and try yourself. All the operational steps shown only require a standard RF power amplifier which should be available in almost every lab. So, before we get properly started, we hope you enjoy this video show and much success in becoming familiar with network analysis in general, and our R&S products in particular.
