The test reference: now for terrestrial digital TV too: DVB-T Test Receiver EFA-T
After successful startup of the first European DVB-T network (terrestrial digital video broadcasting) in Britain with currently over 500000 users, DVB-T is gaining ground in Europe at an ever faster pace. In this context the new DVB-T model of the EFA family of test receivers meets the demand for high-precision reception measurements. Compact in design and featuring comprehensive automatic test func-tionality, the instrument is ideal in R&D, transmission modulator production and
operative monitoring of TV signals.

Out in the wilds - air traffic control in no-man's-land Photo Werk Köln: Mobile Air Traffic Control Tower MX400
Mobile Air Traffic Control Tower MX400 (FIG 1) from Rohde &Schwarz was designed for versatility. It is used worldwide wherever reliable air traffic has to be taken up within a minimum of time and the necessary infrastructure is lacking. It has been tried and tested on many occasions under the most adverse conditions and is being used by international customers, among them the peacekeeping forces in Kosovo.

Unique measuring instruments for wavelength division multiplex: Optical Network Analyzer Q7750 and Optical Chirpform Test Set Q7606
The enormous amount of data distributed today around the globe is mostly trans-mitted
via fiber-optic cables, submarine cables featuring largely in this. An efficient way of increasing the data rate in fiber-optic cable networks is to transmit several optical wavelengths using the wavelength division multiplex method. ADVANTEST, a cooperating partner of Rohde &Schwarz for many years, has launched two completely new and unique instruments on the world market for measurements on active and passive components in this application.

Clear layout instead of cable jungle - flexible wiring of test systems: Communication System Panel TS-CSP
Automatic test systems for functional tests and final testing of electronic products require a large variety of DUT fixtures, stimulus signals, etc. Soon there is a tangle of connecting cables and it gets even worse if something has to be changed. Communication System Panel TS-CSP with its switch matrix modules is the solution to this problem. It was specially designed for use in production test systems and establishes any kind of connection between DUT and measuring instruments efficiently and cost-effectively. Convenient software makes it easy for the user to have everything under
control and to make changes quickly and error-free.

Measurements made easy: firm grip on complex problems: Monitoring DAB and DVB-T transmitter systems
To identify transmitters, handle interference and verify compliance with stipulated conditions for authorization, the monitoring services of licensing authorities must be capable of measuring the technical parameters of transmitter systems off air. Rohde & Schwarz offers an extensive range of monitoring and measuring equipment for this purpose.

Let's go west: ATSC ready for takeoff: MPEG2 measurement generators and decoders
A special standard complying with national requirements is used in the US for terrestrial broadcasting of digital TV signals: ATSC (Advanced Television Systems Committee). Same as the European DVB standard, ATSC is based on MPEG2 coding but it differs in some essential features. Several countries in South America and Asia are about to adopt this standard. So Rohde &Schwarz has integrated the ATSC standard in all its measuring instruments concerned.

A precision instrument that also analyzes arbitrary QAM signals: TV Test Receiver EFA
Quadrature amplitude modulation (QAM) is increasingly gaining in importance in modern communication and transmission systems, offering, as it does, particularly high spectrum effi-ciency
and reliability in digital data transmission. This applies to wired and wireless links alike. TV Test Receiver EFA from Rohde & Schwarz, the test reference for analog and digital TV signals, analyzes and displays even arbitrary QAM signals with high precision without special synchronization sequences.

EMC test centers of any size - precise,fully automatic and universal:
Decades of experience and an allround product range have made Rohde & Schwarz a market leader in the field of EMC test technology and EMC test centers. A large number of renowned companies of the automobile, consumer electronics and mechanical engineering industry have for many years relied on its EMC technology, covering everything from small EUTs to wide-body aircraft. Recently Audi put its new EMC test center into operation, fully equipped with Rohde & Schwarz technology. This article gives an example of the EMC test center concept that has already proven
itself at other well-known companies.
