Measurement deviations due to systematic errors of a network analysis system can be drastically reduced by an appropriate system error calibration. After system error correction, the residual measurement uncertainties are - besides the stability, linearity, and dynamic range of the network analyzer system - mainly affected by the quality of the calibration standards and the repeatability of the connections. The effective measurement accuracy of the network analysis system can be determined using the results of successive verification measurements utilizing highly precise verification standards.

Integrating automotive radar sensors into cars is very challenging. Radars operate behind bumpers, design emblems, in side mirrors or other plastic parts of the car. All radome materials need to be sufficiently transparent and homogeneous for automotive radars, which operate in the 77 GHz and 79 GHz band or even both simultaneously. The new system measures, visualizes and analyzes radar radomes in a manner you have never seen before. Optimize your radome material for best performance and effective integration of modern automotive radar sensors.

This document presents a simple procedure for network analysis that is more cost-effective than the use of scalar network analyzers. It allows the accurate measurement of the transmission characteristics of filters, amplifiers and frequency converters over a large frequency and dynamic range. In order to reach very high measurement speeds, Rohde & Schwarz signal generators are operated in 'List Mode', and Rohde & Schwarz power meters are operated in 'Buffered Mode.' The required programming for the signal generator and the power meter is illustrated by excerpts from a Visual Basic program which is available, free of charge, upon request.

How to configure generic devices in R&S®ELEKTRA
R&S®ELEKTRA is able to communicate with many devices. Still, it is impossible to integrate drivers for all devices. Hence, R&S®ELEKTRA offers the possibility to integrate any device by configuring a generic driver. The configuration file contains commands that translate the language of the device for R&S®ELEKTRA and vice versa.

Synthetic aperture radar (SAR) uses radar wavelengths for airborne or spaceborne ground mapping. The resolution of the SAR ground map depends on the range and cross-range SAR processing resolution. Cross-range resolution is determined by integrating pulses along a flight path for a period of time to create a synthetic aperture. Longer synthetic apertures result in finer cross-range resolution. Range resolution is achieved by radar waveform bandwidth in the form of a linear frequency modulated (LFM) chirp. Wider bandwidth enables finer range resolution.

Testing multi carrier power amplifiers of the 3rd Generation requires test signals with a high dynamic range. This application note describes how a 4 carrier 3G WCDMA signal can be generated and measured with the application software SET_MC4. The software sets up to 4 SMIQ03HDs to generate the signal, and an FSU or FSQ to immediately evaluate and analyze the Adjacent Channel Leakage Ratio (ACLR) of the power amplifier. The setups are controlled remotely.The SET_MC4 source code is also included. Modify the code to meet your individual requirements or adopt the IEEE-commands into your own setup script.

After a communications satellite is on its target orbit, several routines need to be performed in order to ensure proper performance from the transponders in the payload. The on-orbit measurements are a vital part of the maintenance of a live satellite as well. Operating a satellite channel for an on-orbit measurement rather than the intended application comes with significant opportunity cost and hence test duration needs to be minimized as much as possible. Rohde & Schwarz test and measurement equipment recommended in this paper is market leading not only in terms of measurement accuracy but also offers unparalleled speed of measurement. This application note focuses on satellite post-launch or on-orbit measurement and monitoring strategies used for satellite functionality checks when running maintenance routines. A complementary paper treats pre-launch payload measurements.
