• Universal Radio Communication Tester CMU200: Adding CDMA now provides full 2G capability

  Since the first commercial CDMA network started up in Hong Kong in September 1995, this digital mobile radio standard has established itself internationally. With growth rates rocketing unabated, it today ranks - besides GSM - among the major standards of the second generation. New options now add CDMA test capability to CMU200.

• Signal Analyzer FSIQ: Ready for all measurements on 3GPP base station transmitters

  The selection of broadband CDMA for the third mobile radio generation created testing requirements that cannot or barely be met by conventional instrumentation. Signal Analyzer FSIQ is now in shape for all measurements on base station transmitters defined by the 3GPP standard.

• Spectrum Analyzers FSP/FSU: GSM and EDGE measurements with Application Firmware FS-K5

  GSM, EDGE, HSCSD, GPRS, 3.... /8 shifted PSK - GSM evolution calls for new or modified measurements on the RF signal. Application Firmware FS-K5 for measurements on transmitted GSM/EDGE signals keeps you firmly in touch with all the new developments. Plus FS-K5 combines flexibility for development with very high measurement speed in production.

• Web over DTV: Broadcasting and the Internet: convergence through new applications

  Web over DTV is a convenient and cost-effective solution for distributing Internet resources to TV viewers, for example, and enabling TV providers to integrate extra services into their programs. This article describes a number of new services and applications that will make a major contribution to the success of digital TV (DTV).

• Broadcasting: Transmitter network monitoring

  With NetLink, Rohde&Schwarz is worldwide the first transmitter manufacturer to offer an essential module for service-oriented, standardized remote control and monitoring of broadcast equipment units. The integrated Web server allows access to components of broadcast equipment from the World Wide Web. An SNMP agent ensures connection to a full-coverage network management system.

• Coverage Measurement System ARGUS-FMTV: Optimum use of frequency thanks to reliable forecasts in planning

  New transmitter sites for FM and TV broadcasting are planned with the aid of special software that predicts the wanted field strength of a planned transmitter and the interfering field strength of transmitters already existing in the coverage area by model calculations. To date, however, the real coverage area of a planned transmitter could not be measured until after it was commissioned. So leeway for optimum frequency utilization was not always recognized. With the new Coverage Measurement System ARGUS-FMTV, reliable conclusions can be drawn on the expected coverage limits of a transmitter in the planning phase already.

• TV Test Transmitter SFQ: Now signals to digital cable standard ITU-T/J.83B

  Rohde&Schwarz proves again the innovative and universal concept of TV Test Transmitter SFQ. Equipped to match the North-American terrestrial ATSC standard a year ago, SFQ now comes with a coder for the North-American cable standard ITU-T/ J.83B.

• TV Test Transmitter SFQ: High-precision internal noise source enhances measurement functions

  TV Test Transmitter SFQ can now be fitted with an optional noise generator (SFQ-B5) with internal self-calibration ensuring high carrier/noise ratio (C/N) for all modulation modes (FIG 1). In addition, any number of TV test transmitters featuring this option can be interconnected to produce RF signals of the same and coupled frequency with different interference. Diversity reception of mobile DVB-T receivers can be tested in this way.

• Continued from No. 169: Measurements on MPEG2 and DVB-T signals

  Part 3 of the refresher topic continues the discussion of measurements on DVB-T transmitters. This time the focus is on masks for out-of-band components and measurement of the shoulder distance.

• Rohde&Schwarz direction finder convinces Chinese authority on site:

  Last year China’s State Radio Monitoring Center (SRMC), the national authority responsible for radiomonitoring to ITU guidelines, issued an international ITB for three broadband HF direction finders. This was the first step towards establishing a nationwide shortwave DF network. Rohde& Schwarz won out against strong competition.

• Remote Monitoring and Remote Control System ARCEMIS: Central control of radio systems for air traffic control and air defense

  Air traffic control and air defense require full-coverage ground-to-air communication. This is why VHF/ UHF ground radio equipment is normally distributed countrywide. Frequently, transmitters and receivers are located at separate sites (split-site operation) to prevent collocation interference. ARCEMIS ensures remote-control access to any number of transmitters and receivers from one control center.

• Control Unit GB 208: Reliable radiocommunication with minimum manpower

  The operators of small airports cannot afford whole teams to handle their radio traffic. Consequently they need fast and flexible assignment of radio channels to the operator positions. The new 8-channel Control Unit GB208 is specially matched to the requirements of regional or corporate airfields.
