HSDPA – accelerator for WCDMA: Universal Radio Communication Tester R&S ® CMU 200
HSDPA1), the expansion of WCDMA in third-generation mobile radio, increases transmission rates in data links from base stations to UMTS user equipment to more than 10 Mbit/s. Such high transfer rates allow fast loading of videos to mobile radio equipment, for example. This article examines new principles that are being applied to expand a defined mobile radio standard in this way, and which requirements they place on T&M equipment.

Excellent measurement accuracy up to 50 GHz and higher: Spectrum Analyzer R&S ® FSU 50
The new Spectrum Analyzer R&S ® FSU50 extends the upper frequency limit of the successful product family to 50 GHz. While the existing members of the R&S ® FSU family offer top-quality characteristics with respect to dynamic range, measurement speed and accuracy at lower frequencies, the R&S ® FSU50 provides these same excellent characteristics for frequencies that extend into the microwave range. Options for the rest of the product family can, of course, also be added to the R&S ® FSU50, enabling it to handle a wide range of applications.

Extended measurement functions for analog modulation analysis: Spectrum and Signal Analyzers R&S ® FSP / FSU / FSQ
The R&S ® FS-K7 firmware option for the R&S ® FSP, FSU and FSQ families of spectrum and signal analyzers enables you to measure analog modulation types such as AM, FM and φM. In addition to being able to measure modulation depth or frequency deviation, the latest version of this demodulator also measures modulation distortion such as SINAD or THD. It even performs frequency-selective measurements of modulation harmonics and measures frequency or phase settling.

Signal analysis now up to 40 GHz: Signal Analyzer R&S ® FSQ 40
The new Signal Analyzer R&S ® FSQ 40 expands the product family in the upper microwave range. Large analysis bandwidths, very high dynamic range and sensitivity as well as unique measurement functions – e. g. the Vector Signal Analysis R&S ® FSQ-K70 – are now also available in the frequency range up to 40 GHz.

Compact yet sophisticated: Industrial Controller R&S ® PSL1
Controllers are expected to ensure smooth operation, making them a pivotal part of complex measurement systems. The R&S ® PSL1 from Rohde & Schwarz, the latest member of the R&S ® PSL industrial controller family, is a controller that satisfies ambitious requirements and whose low height is virtually unrivalled.

When it comes to power measurements, a reliable sensor is a must: New Power Sensors for R&S ® NRP, NRT und FSH
Power measurements are pivotal in RF and microwave. Even though frequency-selective measurements with spectrum analyzers are gaining in importance, broadband power sensors will remain your first choice when it comes to high measurement speed, low measurement uncertainty and a favourable price/performance ratio. Rohde & Schwarz has again expanded its sensor families by adding four new types.

Complex signal scenarios at almost no effort: Vector Signal Generator R&S ® SMU 200 A
The high-end Vector Signal Generator R&S ® SMU 200A can house two complete generators with digital modulation capability in a single instrument [1]. This design not only saves 50% in space but also enables you to use applications that have previously either not been possible at all or only at high cost and effort.

Universal test platform for digital TV: Broadcast Test System R&S ® SFU
At NAB 2004, Rohde & Schwarz presented the Broadcast Test System R&S ® SFU as a “test transmitter for innovative TV standards” (FIG 1). Yet the very name of this innovation already led people to suspect “test transmitter” to be an understatement. At IBC 2004 in Amsterdam, Rohde & Schwarz then brought all facts to light: The R&S ® SFUshowed its true colours as a comprehensive system for all test applications related to TV. This article now provides a detailed look at this future-oriented platform.

DVB-T in Germany – the second setup phase is in full swing:
Digital terrestrial TV in Germany – there’s no turning back now. In a concerted effort, a new chapter in terrestrial DVB transmission is being written. Network operators, media companies, program providers, politicians, suppliers and, last but not least, consumers are making DVB-T a full success. The evolution of DVB-T in Germany proves that new transmission methods can be successfully introduced, provided the political environment is favourable, i.e. the transition periods must be clearly defined and predictable. As a leading supplier of DVB-T transmission and T&M equipment, Rohde & Schwarz is right at the forefront.

Software defined radios – software aspects and the future (2):
Part 1 of this article in the previous issue of News from Rohde & Schwarz (No. 182) discussed the effect of the software defined radio concept on radio equipment architecture. This follow-up article examines the effect on software structure and the software development process. It also provides a brief look at the future.

VHF/UHF DF network of German RegTP subject to nationwide modernization:
For decades, the German Regulatory Authority for Post and Telecommunication (RegTP) has operated a network of VHF/UHF direction finders to carry out governmental tasks defined within the scope of the International Telecommunication Union (ITU). In 1995, 1997 and 2000, the RegTP issued international tenders for modernizing its DF network. Rohde & Schwarz was selected over international competitors.
