• Audio analysis today and tomorrow: Audio Analyzer UPL

  Rohde & Schwarz has extended its range of audio analyzers by UPL, the “younger brother” of UPD, which still holds the top position in audio measurements. UPL is mainly for use in production tests on digital and analog audio units both in the consumer and professional sectors.

• Compact EMC test cell of high field homogeneity and wide frequency range: EMC Test Cell S-LINE

  In S-LINE, Rohde & Schwarz offers a favourably priced test cell for measuring susceptibility to electromagnetic fields in the frequency range 150 kHz to 1 GHz in the development phase. The test cell, which comes in two sizes, is an attractively priced alternative to compact anechoic chambers. By generating the field using a symmetrical line, S-LINE offers a larger test volume than conventional cells.

• Analog and digital signals for receiver measurements up to 6 GHz: Signal Generator SME06/SMT06

  The boom in the communications sector is continuing. More and more mobileradio networks and new radiocommunication applications are being devised. As the frequency bands below 3 GHz are already densely occupied, increasing use will have to be made of the region above 3 GHz. Rohde & Schwarz has responded to this trend by extending its line of signal generators by two new models: SME06 and SMT06 for the frequency range up to 6 GHz.

• TV reception with analog and digital sound from outer space: Satellite Receiver CT200RS

  As an extension to the CATV Headend Equipment CT200, Rohde & Schwarz now offers a satellite receiver for analog TV programs able to receive both conventional two-channel analog and digital ADR programs. Thanks to the comprehensive remote-control capabilities of the system components, a new concept for broadband cable networks can be implemented.

• Data transmission without data line, audio measurements without program interruption: Audio Data Transmission System ADAS and Audio Monitoring System AMON

  Broadcasting 24 hours a day leaves no time for classic transmitter measurements. With Audio Monitoring System AMON it is now possible for the first time to monitor the quality of the supplied and transmitted television/radio program during program time. This means programs no longer have to be interrupted to carry out measurements, not even for a short time. Moreover, no additional data lines from the studio to the transmitter are required since additional data – such as dynamic RDS data – are transmitted via modulation feed lines by AMON and/or Audio Data Transmission System ADAS.

• Testing GSM/PCN/PCS base stations in production, installation and service with CMD54/57:

  Base stations for digital mobile radio must function reliably at all times. To guarantee this, the transceivers are subjected to stringent quality tests at all stages of production from the individual module to the ready-made product, and key RF parameters are measured during on-site installation and during service. However different the measurement tasks may be, they can all be performed with a single compact test system – Digital Radiocommunication Tester CMD54/57 (FIG 1)*.

• Container location from space:

  In COLOS (Container Location System) Rohde & Schwarz offers one of the most advanced and powerful systems for locating straddle carriers. Rohde & Schwarz is the first company worldwide to install an automatic, satellitebased position location system of this type in a container terminal, situated at the Buchard quay in Hamburg, with turnover of around 15 million tons of goods and space for 35,000 standardized containers (FIG 1).

• Automatic measurements on tape recorders using Audio Analyzer UPD:

  Live transmission of sound and TV programs tends to be the exception. Normally programs are stored on magnetic tapes and replayed whenever required or when broadcast. Sound and TV programs are also filed away on magnetic tapes. It must be ensured, of course, that this conservation does not impair audio or video quality.

• DVTS – video sequence for assessing MPEG encoders:

  What is picture quality? How do you define TV picture quality? Up to now things were relatively simple. The picture quality determined in subjective tests with large groups of viewers on representative examples was closely correlated with a number of measurement results, the assessment of which allowed reliable conclusions to be drawn. That was the world of analog TV.

• RF switch units simplify type-approval tests for mobile radio:

  A variety of measurements are stipulated for type-approval tests of mobile radios and base stations. The specifications of the European Telecommunication Standards Institute (ETSI) define measurements of RF parameters and measurements at different layers. These can be carried out fully automatically by systems for mobile-radio type-approval testing from Rohde & Schwarz.

• Digital modulation and mobile radio (II):

  2 Basic modulation techniques The amplitude, frequency and/or phase of the RF or baseband signal described by equations (2) to (6) are modified by the data signal so that the information it represent is impressed on the RF signal. The terms M-ary amplitude, frequency or phase modulation are used to indicate which parameter is varied to represent the information. The term keying is used for digital modulation. The abbreviations ASK for amplitude-shift keying, FSK for frequency-shift keying and PSK for phase-shift keying are widely used internationally.

• ESxS-K1 – attractively priced Windows software for EMC measurements:

  The automation of EMC measurements in development and production has become a topic of interest since the coming into force of the electromagnetic compatibility law (European EMC Directive 89/336/EEC) this year. Labelling electrical and electronic products with the CE mark is now stipulated by law to indicate compliance with international standards for electromagnetic interference and susceptibility.

• ALADIN and ARAMIS message-handling software – convenient data transmission by shortwave:

  It is a popular fallacy that data transmission by shortwave is unreliable, complicated and out of date. With the aid of Message-Handling Software Packages ALADIN (Automatic Link And Data Interchange Network) and ARAMIS (Automatic Radio Message Interchange System), shortwave becomes increasingly attractive in the modern communications world.

• Object-oriented software development for computer-aided, mobile data transmission:

  Object-oriented software development is in part based on concepts already known for some time; it is however only in the past five years that it has become a topic of general interest. There are various definitions as to when an approach can be regarded as object-oriented. In contrast to the commonly employed function- or data-oriented approaches, object-oriented software development combines data and functions in such a way that they reflect as closely as possible the concrete and abstract objects of the real world.

• The “lifeline” to rescuers in the air:

  In summer 1995 Rohde & Schwarz won the order to supply a blanket radio network for the SAR service (search and rescue) of the German Air Force. This organization of the Federal Armed Forces is primarily a service to support military operations. And as part of the national search and rescue service of the Federal Republic of Germany, it helps any aircraft and – in cooperation with Deutsche Gesellschaft zur Rettung Schiffbrüchiger (German society for rescuing shipwrecked persons) – any vessel in an emergency situation.

• Rohde & Schwarz FM and TV transmitters provide Greater Brussels with entertainment:

  It can hardly be overlooked, the 300-m high tower in a rural area around Leeuw-Saint-Pierre, directly located on the route to Pepingen in the heartland of Flemish Brabant (FIG). Extremely powerful sound-broadcast and TV transmitters from Rohde & Schwarz are operated in this tower. The whole story began because of an accident.

• A vision comes true – trunked radio for United Arab Emirates:

  The United Arab Emirates (UAE) with approx. 2.2 million inhabitants are a federation of seven emirates (Abu Dhabi, Dubai, Sharjah, Ras Al Khaimah, Fujairah, Um Al Qaiwain, Ajman) that were united in a common state in 1971. The Emirates stretch over an area of 90,600 km2.
